British Rail – InterCity Catering

Standard

I have travelled on the West Coast Main Line in Britain for many years, from the days of steam, to the days of the Pendolino, and it seems to me all that the general public are fed is a diet of stories about the curly sandwich. This seemed especially true of the nationalised network.

Inter City Press Release Images March 1993 1The last time I made a journey by a main line service, all that seemed to be on offer was a vending machine, several varieties of crisp, bread rolls, burgers and a coffee from an automated dispensing device. Fast food seems to have taken a stranglehold on train travel in the 21st Century.

Well clearly that’s not much better than the impression that the nationalised system was offering nothing more than a dried up sandwich, and watery tea – or coffee.

Inter City Press Release Images March 1993Back in the later British Rail years, where InterCity was making a profit, the food offering could be quite impressive too. In fact, under BR’s Sectorisation – InterCity was set up in 1987, and made an operating profit of £57 million in its first year, £56 million in 1989, and £49 million in 1990. That despite a cut by the Government of 29% in the passenger grant for rail operations. (Yes, I know it covered other BR sectors, but it would have been impacted.)

In the Spring of 1993, under the custodianship of Chris Green, BR InterCity embarked on a marketing campaign, following a successful introduction in 1992 of what were described as “Express Diner light menus”. This resulted in a 20% increase in the demand for restaurant car meals, and in 1993 more innovation was introduced, including the “Great British Afternoon Tea”

The “Express Diner” menu had a wider choice of meals, including: Rack of Ribs with Barbecue Sauce, Cumberland Sausage and Mash, and Steak and Kidney Pudding alongside existing items such as Fish and Chips and Rib 
Steak. They also went on to include innovations as Chicken Tikka Masala, Beef Stew and Dumplings and Thai-style vegetables with rice
, Jacket Potatoes and even Pizza. (Obviously a novelty in the 1990s!) Oh, yes, and of course a selection of reasonably priced wines was available for lunch and dinner.

Now I’m not suggesting that they were all a great success – but considering the sector’s profitability as a nationalized enterprise, they were giving it a go. At the same time this was happening, of course the 1991 EU Directive about separating infrastructure from operations was being put in place, and the next few years became chaotic, and these innovations dried up.

Mark III Coach Interiors – 1980s

A nice spacious interior in the Mark III coaches from the late 1980s – in this case a First Class Open.

Another generation of the Mark III design was – unsurprisingly the Mark IIIb, but in this example a First Open with an on board telephone. After your meal, why not make a phone call from the train – so long as you had cash or a phone card in 1986 you could.

Today’s fare is a staggering list of coffees – or at least, various ways of serving coffee – together wraps, bagels, burgers and ciabatta rolls, along with a range of wines, beers and spirits, and even porridge. But that’s in the on-board shop section, alongside the usual vending machines. The only way to get a meal served at a table is in first class though, and only on certain trains – and the menu, like our tastes may have changed – and now includes such as mushrooms in a pastry case with butternut squash.

Not something that was common 20 years ago – but then neither were the veggie and deli specials. Even first class travel on some trains does not mean you get a meal, it may be just wraps, sandwiches or rolls for lunch, or perhaps grilled salmon, beef and potato pie, or salad for an evening repast.

Train Innovations Too

But the on-board food and menu changes were not the only improvements to be planned for the early 90s, in BR days. The existing HST sets and coaches were goiung to be fitted with a range of facilities, many of which we take for granted today. This is what was planned in 1993 – 26 YEARS AGO! :-

  • Audio entertainment system with a selection of CD and FM radio channels available at seat.
  • Electronic seat reservation information on luggage racks and new information displays (including time and journey information using a satellite-based system).
  • Improved toilets with new vanity units and lighting.
  • Brighter entrances to provide a better, warmer welcome for customers.
  • Improved tables, seat access and luggage storage.

Inter City Press Release Images March 1993 3Changes to the internal layout of the coaches was intended to break the saloon into smaller areas, with the Senior Conductor’s office located in the centre of 
the train; near the buffet and accommodation for the disabled, for better customer accessibility.

Clearly some of these were incorporated into the Pendolino trains in later years – some 10 years after BR had planned to introduce them.

Not long after the 1993 innovations, along came the likes of the Pendolino and Voyager fixed formation trains from Bombardier and other makers, and hey presto, the above seat reservation details appeared – and of course in-coach entertainment.

When all is said and done though, it has always been unfair to cast aspersions at the state of the on-board catering on British Rail, as undoubtedly, there are occasions when even 20 odd years later, there are no doubt examples of failures. It is not nationalised rail system that was the cause of these issues, but maybe it was us – our changing tastes in food and service.

Inter City Press Release Images March 1993 4

Maybe the initiatives were from BR’s InterCity Sector, but we just took a different path to get there. At least that sector was profitable – but then, maybe there is another story there too.

 

 

 

The whole idea behind this marketing campaign was to persuade travellers not to do this:

Hong Kong Metro – 40 Years On

Standard

It was once described as the largest building project in Asia, and it carried its first fare paying passengers on 1 October 1979 when the 8.5km section of the Metro between Kwun Tong and Shek Kip Mei was opened to the public.

Mtrc79It is also 40 years ago this month that another order was placed with Metro-Cammell for the growing Hong Kong MRT, just three years after they were awarded a £35 million order for 140 trains in November 1976. GEC traction and Metro-Cammell’s combined success with the first orders, was followed in November 1979 by another £40 million order for a further 135 multiple unit vehicles for the Kowloon-Canton railway.   This came hard on the heels – just five weeks later – of the order for a further 150
 metro cars worth £50 million for the MTR routes.

Original MRT train - from Railpower 39

Almost straight out of the box. An original Metro-Cammell built MRT train for Hong Kong. Though much changed in appearance, passenger facilities and traction control systems, they are still at work today.

By that time, contracts worth over £100 million for electrical, mechanical and civil engineering work had already been placed with UK engineering firms. The initial multi-contract E11 awarded by the MRTC involved GEC Traction and Metro-Cammell, requiring close co-operation between the three organisations for the supply and installation of the electrical and mechanical equipment.

The first contracts on the Modified Initial System were placed almost ten years after a report on the problems of road traffic congestion was published by the Hong Kong Government. This was aimed at resolving the territory’s transport question further.

Hong Kong MTR MapThe mechanical and electrical contracts placed by the Hong Kong Government for the Modified Initial System (MIS), were awarded against an extremely tight schedule. The first train set was scheduled for delivery in 1979 and the whole 15.6 route km system was planned to open early in 1980.  The MIS for Hong Kong was swiftly followed by the Tsuen Wan extension, with the obvious demand for more rolling stock, and by 1982, GEC Traction had supplied more than 400 sets to the MRT Corporation.

Alongside this, the 34km route of the Kowloon to Lo Wu line was being doubled and electrified at 25kV a.c. using a simple, overhead catenary construction, similar to that used by British Rail in the UK.

In the export market, the Hong Kong MRT was considered the first major project success for GEC Transportation Projects, established as a subsidiary of GEC Traction and based in Manchester, to design and manage such turnkey projects. The Mass Transit system was entirely new, with two lines providing links between the Central District of Hong Kong Island and the business and residential areas of Kowloon. The mass transit railway used an overhead contact system, electrified at 1500Vd.c. It was intended at one time that this line would be
 electrified using a shrouded conductor
 rail, but it was decided that safety
 margins would be improved using 1500Vd.c. catenary. At the same time, two extensions to the MRT were planned 10.6km to Tuen Wan, and the 12.5km Island Line, with completion in 1986.

Kowloon to Canton (Lo Wu)

Work began on the modernisation of the 34km Kowloon-Canton Railway, in early 1980, with the design, installation, supply and commissioning of the overhead equipment awarded to Balfour Beatty Power Construction.

Metro-Cammell
 had also signed a contract with the Hong Kong
 Government to supply 135 electric
 multiple unit vehicles, to operate 
inner and outer suburban services on the
 Kowloon Canton Railway, which was being
 modernised and electrified. The fleet of rail
cars, worth £40million, were designed to be operated as
 three-car sets with up to four sets running in 
multiple.

The electrical equipment and traction power infrastructure was again being supplied by GEC Traction, from Preston and Stafford, with the MRT and extension lines electrified at 1500V d.c overhead, and the Kowloon to Canton route at the standard 25kV a.c., overhead.

Rolling stock

The trains for both the
 Mass Transit and Kowloon-Canton 
Railways, were built by Metro-Cammell. The original mass transit cars
 had a very high capacity, with seats 
for 48 passengers, and standing room
 for more than 300, in a length of 22m
and overall width of 3m. At the time, the MRT cars were believed to have the highest capacity of any metro car in the world. With such high density, getting passengers on and off required the provision of five pairs of sliding doors on each side of the car.

GEC Traction Hong Kong BrochureThe cars for
 the Modified Initial System, and Tsuen
Wan Extension were arranged in six-car formations, and due to the demanding operating requirements, all axles were motored, to give a nominal acceleration of 1.3m/s 2. Though this was increased in practice, because many of the stations along the route were constructed on ‘humps’. The MRT cars, ultimately in eight-car formations were required to operate at 90 seconds headway between trains, and a two minute intervals with ATO (Automatic Train Operation) in use.

The body shell was common for the three types of car on the KCR, and similar to that for the Hong Kong Mass Transit cars. They differed largely only because the KCR sets had fewer side doors, and narrower gangways between cars than the MRT vehicles. Electrically the KCR propulsion equipment was almost entirely derived from that supplied to British Rail.

GEC Traction supplied the propulsion equipment, which included conventional, camshaft control systems,· although consideration had been given in the early stages to using more advanced, thyristor chopper control. An important advantage of using chopper control is the system’s ability to regenerate during braking, but the hump layout ofmany ofthe mass transit stations rendered its application less useful. By 1982, Metro-Cammell had received orders for 558 vehicles for the mass transit system, with the final contract covering 22 power and 106 trailer cars for the Island Line extension. A total of 18 powered cars were ordered with thyristor control equipment in later years, in orders worth some £l0m.

In the UK, during the 1970s, the Tyneside Metro was constructed, which proved beneficial for both Metro-Cammell and GEC Traction, since te first Hong Kong MRT cars were sent for trials on the Tyneside Metro’s test track, prior to dispatch to the Far East.

The orders for Metro-Cammell and GEC Traction continued to come in during the 1980s, with additional MTR trains for the Island Line extension, and more three-car trains for the KCR. The last order for what was later classed as M-Class trains, were delivered from Metro-Cammell in Birmingham in 1988/89. However, it was not the last order, as in 1992, and order was placed with GEC Althom (who had by then acquired Metro-Cammell), for another 64 cars, for the MRT.
The MIS trains built by Metro-Cammell were – indeed are – classified as “M-Stock” by the MRT in Hong Kong, and they have undergone various improvements and changes. The initial modifications included altering the front end, to “modernise” its appearance, and the fitting of passenger information systems. All of the original builds were fitted with GTO Chopper control between 1992 and 1995.

This final order included an option for 24 further vehicles, and all 88 were supplied to Hong Kong as a set of parts, which were assembled at the Kowloon Bay Depot. Some of these – by now classed as H-Stock – were refurbished for use on Hong Kong’s Disneyland Line.

The original Kowloon-Canton units were designed for longer journeys, and included slightly different layouts or inner and outer suburban trains, but the general construction is similar to the mass transit trains, with main structural profiles common to both designs. In three-car sets – up to four sets could be coupled in multiple to give a 12-car train), the outer suburban sets have a capacity for 884 passengers and 961 for the inner suburban sets. With full width driving cabs at each end, every three-car set is a self-contained unit.

We see climate as a 21st century issue, but of course in tropical, and sub-tropical climates, there has always been the ever present problem of torrential downpours, from storms – be they hurricanes or typhoons, along with dramatic temperature variations. The climate is such in Hong Kong, that the vehicles, and their passengers were expected to withstand extremes of temperature, from 0 to 40 degrees, up to 100% humidity, and even required to run through flood water in some sections, as a result of the impact of Typhoons.

These trains are still in service today, but have undergone a number of changes, and the original Hong Kong MTR and Kowloon-Canton Railways have seen considerable changes and modifications since the 1980s.  The original KCR trains were converted by Alstom to 12-car sets, and the original 3 sliding doors were increased by the adition of a further 2 doors per side, and an emergency door in each cab front. The cab fronts were also modified, and entirely new passenger information systems were installed – all of this work was carried out between 1996 and 1999, to extend the life of these trains. Further changes included the fitting of ATO/ATC control systems, and today, 20 years later, they are still in use – now classed as Mid-Life Refurbishment Train (MLR).

So much has changed over the years in Hong Kong, what with the new airport at Chek Lap Kok, and the suspension bridge carrying the metro to the airport, along with further new lines, and a link to the Disney resort. On the railway, several refurbishments of the original M-Trains – which are still running, and the fitting of automatic train Control (ATC), the now almost universal Platform Screen Doors on metros around the world – but the trains from

Class 158 – New Lights for Old

The BREL built “Express Sprinter” dmu’s of 1989-92, constructed at Derby’s Litchurch Lane Works are some 30 years old now, and have been dispersed around the UK through BR’s Regional Railways Sector, to the post-privatisation TOCs.  The 40 two-car sets allocated to Abellio/Scotrail may soon be receiving another minor refurb, with a proposal to fit LED lighting in the driving cabs and saloons – or perhaps not.

LED Procurement Tender Notice extract

Extract from the August 2019 procurement notice for Abellio Scotrail

The successful tenderer was to be retrofit the 40 2-car sets with the fitting – and the ongoing management of these installations, and the original tender was announced in December 2018, then cancelled, and re-posted in July 2019. Both the interior lighting question and these last BR built multiple units have had a bit of a chequered history, and their design has been unkindly referred to in some quarters as a “garden shed” approach. Yet still, after more than three decades of service, they are fulfilling some of the intermediate to long distance passenger train duties – at least in Scotland.

Class 158 in 1990 on Glasgow to EdinburghThe Class 158 “Express Sprinter” were the 3rd gestation of the British Rail “Sprinter” range of 2nd generation dmus. Unlike the earlier “Provincial Sector” designs, these were not designed from either older emu designs, like the ‘Sprinter’ series, but they were driven by the 1980s financial constraints on BR. At the time, between 1989 and 1991, the application of inter-city style seating and layout for these longer distance regional services were still dependent on the first generation dmu’s. These were by this time more than 30 years old, and increasingly unreliable, and the refurbishment programmes of the 1970s really did nothing other than a new paint job, or interiors. Then there was the ongoing cost of asbestos removal from the 1950s designs, which, coupled with the financial strictures and operations in the days of sectorisation in the 1980s, ultimately, led to the building of new multiple units.

The end result was the “Express Sprinter”, built at Derby, to the BREL design, and using the key features of the main line and inter-city rolling stock designs, to meet the increased needs and performance criteria for Provincial Sector. The BREL built 158s were first put to work on the Scotrail Sector, over the time when BREL was being privatised by the government, firstly as BREL Group Ltd under ABB Transportation, and later as Adtranz (ABB-Daimler Benz). Each of which is now consigned to the history books. BREL built 447 vehicles, most as 2-car sets, but with a small number as 3-car, and the last was handed over in 1991.

The idea of this latest modification for Abellio ScotRail Ltd was to gain the benefits from energy saving and an increased lighting lifespan on these trains. The most recent upgrade/refurb of the Scotrail units was carried out at the now closed Springburn Works, then operated by Knorr-Bremse, back in 2015.  The work carried out then included the current ‘Saltire’ livery and modernisation of the interiors with new carpets, surface finishes and toilets.  At the same time, the 137-seat trains were equipped with new CCTV systems and automatic passenger-counting systems.

The 2015 renovation and upgrade/update work was carried out at Springburn under the Railcare banner.

The 2015 renovation and upgrade/update work was carried out at Springburn under the Railcare banner.

So, new lights for old may be seen as another minor, but useful upgrade to this long-lived type of rolling stock.  The technology itself may not seem so new, but ranks up there with proposals some years ago that one single light source could supply – through the use of fibre-optic cable – individual lighting throughout a train.  Gone are the days of 60-watt incandescent bulbs in the centre of the passenger compartment – now departing are the harsh glare of fluorescent tubes, with or without luminaires on the coach ceiling.

Some 17 years ago, I wrote about the advances in lighting technology on stations and on trains, for passenger circulating areas, and for on-board functions.  It was back then when the use of laser-optics was being advanced as the way forward, like this:

The Future is Fibre-Optic

  • A great deal of advancement has been seen recently in the use of fibre-optics for lighting purposes. Unlike conventional lighting, with fibre-optic technology, only the light is transmitted. The principal areas where this technology can be used may be summarised as:

  • Difficult access (lack of height and space)

  • Reduced maintenance (multiple lighting points from one lamp)

  • Where objects may be sensitive to heat and ultra violet rays

  • Regulating light in specific places, with minimum visual intrusion

  • Use of fibre-optic cable in data communications, and indeed for entertainment or decorative purposes is not new, but it is state of the art as far as the specialist railway environment is concerned. In principle, its use is based on light from a single source – probably the most obvious departure from conventional practice – and transmission of light along a group of fibres, with the light emitted in a concentrated beam at the remote end of each fibre. This technology in railway use could lead to the elimination not only of the multiple lamps and luminaires, but also the costs of maintaining illumination at recommended and safe levels – especially on board trains.

  • Applications of this technology for the passenger are perhaps most obvious for such activities as reading. Other uses could benefit the train crews, on the driver’s control desk instrumentation – much like their use in cars today. A major advantage is the fact that no heat is generated at the point of illumination, so perhaps a beneficial application could see its use in areas where light but no heat is needed – fuel tank levels, or similar gauges and indicators in hazardous or hard to reach areas for instance. Alternatively perhaps, a way of providing a light source for CCTV and other monitoring systems regularly used today.

  • Ultimately, the future use of fibre-optics in railway lighting applications looks positive. As the production of second-generation metal halide and micro discharge lamps increases the efficiency of the technology, the future is indeed brighter.

This seemed to be the way forward back at the beginning of the 21st century, and now, approaching ¼ of the century, the use of LED (Light Emitting Diodes), has become the lighting source of choice. In fact, LED tube lighting is an ideal candidate for retrofitting to the good old standard fluorescent tube lighting on trains, with some designs being a simple replacement of the older tubes, using the same fittings. The technology itself is claimed to result in an energy saving of up to 75%, and has been in use with TfL in London for the past couple of years, reducing both energy and maintenance costs.

Shining a light on historical sites too, LED lighting has been installed at Rainhill on Merseyside – so even the location with one of he greatest claims to fame for Victorian ‘new technology’ is now an example in the 21st century – 190 years later. Of course, today everything has to have the adjective “smart” attached to it, and lighting on the railway is no exception, so now we also have ‘smart lighting’ – for which no doubt an ‘app’ will be available – soon?

I started off this little item just thinking about the Class 158 and its new lights, but there is much more to lighting on the rail network today, so we will revisit this story for a more detailed look at the technology shortly. So much for fibre-optic lighting!

Deltics in Retrospect – Part 1

Standard

The DeItics, or rather the 22 locomotives originally designated English Electric Type 5 Co-Co diesel-electric, over a working life of more than twenty years became top favourites with all rail enthusiasts as they carried out the express passenger duties on the East Coast Main Line. And yet, initially, the design was not in tended for the Eastern Region at all, but the London Midland. Following the highly successful operation of the prototype Deltic locomotive, on LMR and ER metals, it was decided to place an order with English Electric for a production version. In essence this retained the twin I8-cylinder ‘Deltic’ engines of the prototype in a stretched body, with a number of other detail modifications, providing BR with what was at the time the world’s most powerful single unit diesel locomotive.

The first three production Deltics appeared in March 1961 and were allocated to the Scottish, Eastern and North Eastern Regions respectively. They were numbered D9000-02 in the then current numbering scheme. They were the result of six years running experience with the prototype; which remained the property of English Electric until its withdrawal and preservation in the Science Museum in 1963. The prototype had experienced only minor problems during the 400,000miles it covered in service, almost all of which centred around the Napier ‘Deltic’ engine. It was in this, in fact, that the unique nature of the Deltic locomotive was contained. The power unit was developed from a design prepared for the Admiralty in the early 1950s for its ‘Dark’ class fast patrol boats – a lightweight two-stroke diesel, opposed piston, water cooled engine. The cylinders-eighteen in all – were arranged in banks of six around the three sides of an inverted triangle – hence the Deltic name. Happily, the engines installed in the rail version had a much more successful career than those for the Royal Navy.

The genesis of the ‘Deltic’ design was outlined in some draft notes on English Electric’s history prepared for GEC Traction’s publicity department around 1970, and included this summary:

1952

The development of a completely new ultra lightweight high speed 2-stroke diesel engine by D. Napier & Son, initiated an investigation 
into the traction potential of the new engine. In due course emerged the parameters for the design of a revolutionary single-unit diesel-electric locomotive of a power substantially greater than existed at the time (or 
for some years after it’s subsequent introduction).

Alongside the production of well established designs for export the prototype began to take shape, finally going into proving service on the L.M.Region of B.R. in 1956, the most powerful single-unit d.e. loco in the world with the highest power/weight ratio. With 3,300 hp from its two 18-cyl Napier engines, the “Deltic” loco weighed some 108 tons, max. axle loading – 18 tons.

During extensive service trials, speeds of well over 120 mile/hour were reputed to have been reached (unofficially), due, principally to the extremely smooth riding of the loco under which speeds downgrade could build up without the rougher riding more normally associated with speeds around 100 mile/hour at that time.”

The notes went on to highlight the steady development of English Electric’s diesel engines and its rail traction success. The production “Deltic” locomotives went on to become legends on a par, if not exceeding that of the Gresley or Stanier pacific steam locomotives.

Teething troubles in the design were basically the result of its transfer to rail traction use, and for the prototype, in addition to the two engines it carried, no less than three were maintained as spares. This was partly for test purposes, and partly to seek out the cause and cure for major problems of erratic valve operation. On the locomotive, with two engines, should one fail completely, it was still possible to move using only the one remaining engine.

Ironically, the prototype Deltic was withdrawn from service and returned to the Vulcan Foundry in the same month the as the first production units appeared. A piston failure occurred while the locomotive was working a Kings Cross to Doncaster service, which badly damaged one of the engines, and during March, the power plant, train-heating boiler, traction motors and control system was removed. It was planned to scrap the remaining shell, before the proposal to display it in the Science Museum was made – and fortunately this proposal was successful.

Deltic Prototype from Dec 1955 BR LM Region Magazine

The prototype as portrayed in the December 1955 issue of the London Midland Region Magazine – worth noting is the statement at the foot of the caption, stating that it had been built for export.

The table below gives the leading dimensions and other principal details of the 22 Deltic locomotives, in ‘as built’ condition.

Deltic leading dimensions

* Although when introduced, all the Deltics were fitted with both air and vacuum brake equipment, the latter being required since a majority of the passenger stock was still vacuum-fitted. The air brake equipment was for loco use only, and in 1967-8, the entire class was fitted with train air brake equipment.

Mechanical Details

(1) Power Equipment and Transmission

The two engines fitted into each locomotive were high-speed two-stroke diesels, each of which developed 1,650hp from eighteen cylinders. The design comprised three banks of six cylinders arranged around the sides of an inverted equilateral triangle, with all the piston heads opposite one another. This meant that instead of having the main crankshafts in the conventional position at the base of the engine, they were positioned at the three apexes of the triangle.

Deltic Engine ViewsThis complex construction, as previously mentioned was a development of a design produced by Napier for the Admiralty. In fact, the rail traction version, designated type D18-25 maintained the same size cylinders as some of the more powerful marine types, which in the 1950s had reached outputs exceeding 4000hp. One benefit gained from the triangular arrangement was the almost complete balancing of the reciprocating forces.

The pistons themselves were oil-cooled with an aluminium alloy skirt, and a dished alloy crown, screwed and shrunk onto the skirt. Three separate camshafts were fitted to the outer faces of the crankcases, with the fuel injection pumps mounted on the camshaft casings. Lubrication of the engine was based on a ‘dry sump system’, and all bearings and gears were supplied with oil under pressure.
The engines were constructed from three separate cylinder blocks and crankcases, secured by high tensile steel bolts – a method of construction reckoned to give a very strong and rigid structure. At the generator end of each engine a set of phasing gears was provided to drive a common output shaft. From the phasing gearcase, two flexible shafts passed through the uppermost crankcases to drive a centrifugal, double entry scavenge blower. The 5 1/8 in bore cylinders were fitted with steel ‘wet’ type liners with nine exhaust ports arranged around part of the circumference at one end of the liner, and 14 inlet ports around the full circumference at the opposite end.

The generators attached to the output shaft of the phasing gearcase were self-ventilated DC machines, with a continuous rating of 1,650 amps at 660 volts. The phasing gearcase output shaft to which the armatures were attached rotated at 1,125rpm – the speed being stepped down from the crankshaft speed of 1,500 rpm. The auxiliary generators were mounted above the main generators and driven by a take off shaft from the phasing gearcase at 1 2/3 the crankshaft speed. The 110-volt supply was used for excitation of the traction generator field coils, lighting and various ancillary circuits.

With both engines in operation, the load was shared between the auxiliary machines, and the main generators were connected in series to supply the six traction motors. Should one power unit fail, the system was designed to provide full tractive effort, but at only half normal road speed. The six English Electric Type EE 538 traction motors were nose suspended, axle hung machines, driving the respective axles through a pinion mounted on the end of the motor armature shaft, and a gear wheel on the axle. The motors were force ventilated, from blowers mounted in each nose end, and electrically connected as three parallel groups of two motors in series.

In order to improve the speed characteristics over which full locomotive power was available, two stages of traction motor field weakening were provided. Engine cooling was by means of two roof mounted radiator fans, each engine having a pair of fans driven through gearboxes and cardan shafts with universal joints.

(2) Control systems

Control of engine speed was by means of air pressure actuators acting on the spring loading of the engine governors. Excitation of each main generator was altered through the load regulators – multi contact rotary switches. The opening and closing of the contacts was via the engine governor and oil driven vane actuator. This in turn varied the resistance in the main generator field circuit, keeping the respective engine at full load for that specific position of the power handle.

All auxiliary circuits were supplied at 110volts, for the operation of pumps, blowers, compressors, etc. An electrical control cubicle was provided behind each cab bulkhead, and housed all the principal circuit protection devices. General protection devices included automatic correction of wheel slip, which involved a slight reduction in traction motor voltage and application of sand.

This arrangement for controlling wheel slip was also in experimental use in 1961 on the 2000hp English Electric Type 4 No D255.

In the event of high cooling water temperature, or low lubricating oil pressure, the engine affected was shut down automatically. Faults such as these would be indicated on the control desk in the driving cab, together with boiler shut down and general fault lights. The general fault light was linked to secondary fault indication lights in the engine compartment detailing particular faults, such as traction motor blower failure, low water or fuel level. The low fuel level indicator meant that enough fuel for only 50 miles of running remained.

(3) Bogies, Running Gear -General Constructional Features

The bogie main frames and bolsters were fabricated assemblies with the headstocks riveted to them. The general arrangement was similar to the prototype locomotive, though the wheelbase at13ft 6in, equally divided, was shorter. Underhung equalising beams of forged steel were fixed to stirrups incorporated in the axlebox assembly, with the stirrups and equalising brackets being provided with manganese steel liners. Similarly, liners were fitted to the wearing faces of the roller bearing axlebox guides, bolsters, side bearers and centre pivots. The load was transmitted to the bogie through the bolster side bearers and four nests of coil springs to two spring planks suspended by swing links from the bogie frame. Dampers were fitted between the bolster and spring planks. Four pairs of coil springs distributed the load from the solebar to the equalising beam.

This design of swing bolster bogie was also fitted to the English Electric Type 3Co-Co locomotives, and in June 1961,fractures were discovered in the transom webs of two locos, and as a result all locos with this type of bogie were withdrawn whilst a modification was made. This involved the provision of thicker gauge steel for the particular component, and no further trouble was experienced from this source on either the Type 3s or the Deltics. An interesting arrangement of ducting for traction motor cooling air was used, involving a flexible connection to two of the motors through the hollow bogie centre via the bolster, with similar ducting and flexible connections to the third motor. Clasp type brake rigging was fitted, and could be operated directly through the driver’s air brake valve, or operation of the vacuum brake on the train would cause a proportional application of the loco’s brakes to be made. In1967-68 all the Deltics were equipped with a train air brake system for working the latest stock, including air conditioning.

The underframe and body framing was designed as a load bearing structure, built up from cold formed steel sections and carried on two centrally positioned longitudinal members, and rolled steel channel solebars. A steel plate decking was welded to the top of the underframe with wells under the engine/generator units. All exterior and interior panelling was welded with joints ground flush. Fibreglass insulation was provided between the bodyside panels and in the cab, reducing noise and temperature variation. A more than usual proportion of fibreglass was used in the Deltics, with sections being adapted for battery and sand boxes, main cable ducts, instrument panels, cab and equipment compartment doors. The underslung fuel and boiler feed water tanks were welded up from light alloy sheet, and carried between the bogies. Water tanks were insulated and fitted with heating coils. A characteristic steam locomotive fitting was also provided on these advanced diesel locomotives – a water pick up scoop for use on troughs fitted between the rails.

Basically, the body could be divided into five compartments, which were as follows: No 1 end cab, engine room, boiler compartment, engine room, No 2 end cab. In front of each cab, a nose compartment housed various items of equipment. At the No 1 end these included two exhausters, CO2 fire extinguishers and a traction motor blower and air filter. The nose end in front of the No 2 cab – in addition to the traction motor blower and fire fighting appliances – also housed a toilet and the air compressor. In each case, in view of the height of the nose, both Driver and Second man’s positions were on a raised platform within the cab proper, which was provided with an access door on either side. Due to the restriction of space caused by the intrusion of part of the control cubicle into the cab, the two outer doors were sliding, whilst the engine room access doors opened into the cab.

The engines were positioned in. the engine compartments so that the generators faced outwards, ie, towards the cab, and separated by the train-heating boiler. This latter occupied a space12ft I Din in length at the mid-point of the locomotive. It was a Spanner ‘Swirlyflow’ Mk II, with a steaming capacity of 15001b/hr.

The Premier Line

Standard

The London & North Western Railway Co., or “Premier Line” as it ultimately became known, was undoubtedly one of this Country’s premier railway companies, 
The LNWR came into existence following the amalgamation in 1846,of three of the principal west coast companies; the London & Birmingham, Grand Junction and Manchester & Birmingham Railways. The latter however did not fully extend to the limits implied in its title, occupying roughly the same route as the present
 Styal Line into Manchester Piccadilly, with its connection to Birmingham made over Grand Junction metals from Crewe.

The LNWR as it existed in 1846 was divided into Northern and Southern Divisions, with separate Chief Mechanical Engineers (CMEs) for each, not to mention individual livery styles and a number of other things. Wolverton and the Southern Division was in the hands of Edward Bury, from London & Birmingham days, later followed by McConnell. The Northern Division based on Crewe began life under Alexander Allan and Richard Trevithick, and later John Ramsbottom. From 1857 onwards however, the two divisions of the LNWR were merged, with Ramsbottom assuming overall control of the C.M.E.’s side from Crewe.

Lady of the Lake 2-2-2 from BR Magazine

Described as a “Problem” Class loco, No. 531 “Lady of the Lake” was built at the LNWR’s Crewe Works in 1859. The 2-2-0 design was produced when John Ramsbottom was Loco Superintendent. These were not so successful in passenger service as his      2-4-0 ‘Newton’ and the later ‘Precent’ derivatives.

Crewe itself soon assumed considerable importance as major junction, with completion of Robert Stephenson’s Chester & Holyhead line – the “Irish Mail Route”.  The old Grand Junction Railway was also connected northwards from Crewe with the Liverpool & Manchester and Wigan & Preston Railway. The Potteries too, through the North Staffordshire Railway, also had an interest in Crewe and the flowering LNWR. Further north there was the Lancaster & Preston Junction and Lancaster & Carlisle Railways, which later became part of the LNWR empire, though not for some years after the merger of 1846.

To the south, the LNWR was anxious to improve its communication with the capital, avoiding the need for a circuitous route from the manufacturing centres of the north through Birmingham, the Trent Valley line was constructed, though not without some opposition. The opposition to this line came initially from the LNWR itself, since the Trent Valley line was projected originally as a separate company, the LNWR taking it over after the light had been seen, so to speak. At Rugby, connection was made with the fast growing empire of George Hudson’s Midland Railway. In fact, until the Midland opened its own route to London and St. Pancras, that company was obliged to rely on the LNWR for through carriage of its passengers and goods, from the manufacturing districts of the East Midlands, and of course coal from the South Yorkshire Coalfields. There was much antagonism between the two companies at one stage, the Midland threatening to send its traffic to London over the metals of the rival east coast route of the Great Northern Rly. The LNWR was to encounter the Midland again in later years, much further north, with the building of the Settle-Carlisle line.

Motive power in the early days was diminutive, both by modern standards and those of contemporary companies, particularly the broad gauge GWR, whose massive outside framed single wheelers were twice the size of Bury’s bar-framed 0-4-0 and 2-2-0 types. Coaching stock was small by comparison too, though despite this, tales are told of double, triple and even quadruple heading trains out of Euston. About this ti.me too, there appeared from Crewe, one of the Company’s famous and unique locomotive types – the now preserved “Cornwall”, a relatively small engine with massive single driving wheels. Trevithick’s original design though was rather different to the form in which it is preserved today, essentially, in order to lower the centre of gravity, its boiler was carried below the driving wheel axle!

RPBRLY-36

Originally built by Trevithick in 1847, with a boiler beneath the driving axle, “Cornwall” seen here at Crewe, was rebuilt by Ramsbottom to follow a conventional layout. The loco was withdrawn from service in 1927 – some 80 years after building!

A nightmarish proposition for those required to maintain it no doubt. However, not all LNWR motive power was quite so freakish, some solid designs were produced at Wolverton under McConnel, known for some obscure reason as ”Bloomers”. Although again, they were really quite s all designs. In fact the Company was to be beset for many years with motive power of both small size, and in many instances poor performance. Ramsbottom’s ”Newton” class 2-4-0’s though small, were the forerunner of perhaps the Campany’s most successful design of steam locomotive until the early years of the 20th Century. I refer of course to the ever famous “Precedent” class, or as they became popularly known – the “Jumbos”.

Hardwicke - large_NRM_CT_936889

Webb’s early designs for the LNWR were very successful – before he got hung up on coimpunding – and No. 790 in the national collection at the NRM is the most famous of the “Precedent” Class. Building began of 166 of these engines in 1874, but the last of the class was not withdrawn until 1934. Photo courtesy NRM. licensed under a Creative Commons Attribution 4.0 licence

Probably the LNWR’s most “colourful” period coincided with the. arrival of the autocratic F.W. Webb as Chief Mechanical Engineer, and also with those of Richard Moon as Chairman and Capt. Mark Huish as Company Secretary. This trio were, even by Victorian standards, extreme in their attitudes and formidable in the wielding of their power and influence over all who ca.ne into contact, or conflict, with them. Two interesting stories are related over the activities of two members of this trio, though the one concerning Capt. Huish serves to underline his management methods, which, it appears, were learned whilst pirating the South China Sea, in pursuit of the lucrative, but illegal, opium trade; F.W.Webb on the other hand was of a more religious upbringing, his father having been a vicar. Christianity left its mark on this man in an obscure sort of way, for on an occasion whilst paying a visit to one of the workshops at Crewe, upon entering a building which had shortly before seen some form of accident, the area being thick with smoke and fumes, a workman had been overcome by these same fumes. On witnessing this, Webb is reported to have instructed the foreman to take the hapless individual outside, revive him and sack him forthwith. Perhaps in relating this incident, all the reasons are explained for Webb’s dogmatic and obstinate pursuit of the compound locomotive.

Greater Britain 2-2-2-2 Compound

Classic Webb era design of another of the less than successful compounds. The LNWR “Greater Britain” 2-2-2-2 locomotive No. 2525 (LNWR Crewe Works 3292 / 1891) The class consisted of ten of these 2-2-2-2 compound locomotives designed for express passenger work by Francis Webb in 1891.             Photo (c) Historical Railway Images

During this period, between say 1860 and 1900, there occurred the steady expansion of the Euston empire, stretching to the Scottish border and beyond, with the lliance of the Caledonian Railway to across the Irish Sea and the Euston owned Dundalk, Newry & Greenore Railway. Its steamship services ere surpassed by few others, whilst its main line, forever known as the West Coast Route was amongst the busiest and hardest to work of any railway in the country. The LNWR even managed to gain a foothold in West Cumberland, over the Cockermout, Keswick & Penrith line, purchasing the Whitehaven Junction Railway, and having operating agreements and joint ownership with the Furness, of one or two others. By 1870, the LNWR had indeed established a fair sized and extremely profitable railway. In size, with around 1400 miles of track, even this was to more than double by the end of its independent life, it was second only to the GWR; although its 
income was very nearly double that of the company with the broad gauge. It had also, the two important arteries of the Chester & Holyhead, acquired in 1858, and the Lancaster & Carlisle, leased, optimistically perhaps, for 90 years.

Locomotives figure prominently in any account of the “Premier Line” at this time, not surprisingly in view of the almost bewildering number of designs produced by Webb during the period from 1870 to 1903. Webb, as is well known, was an ardent and staunch a supporter of compounding as a means of effecting economies in locomotive operation as any other. He was also ably backed in this respect by the company Chairman – Richard Moon. Moon too was constantly striving for economy, tempered with the desire to maintain the position of the LNWR, and his own naturally, as one of the world’s largest, wealthiest and most respected joint stock companies. This he undoubtedly achieved during his tenure of that office, between 1861 and 1891. But it was perhaps Webb’s brilliance as a mechanical engineer that is remembered most, many of the innovations on this country’s railways in the latter half of the century were the product of his inventive genius. As an example, Adam’s ”Radial Tanks” on the London & South Western Rly. possessed a design of trailing axlebox which owed much of its development to Webb’s own ideas on the LNWR, to say nothing of his patented electro-mechanical interlocking lever frames for signalling!

As a locomotive engineer, Webb was probably second to none. Although remembered most for his largely unsuccessful pursuit of compounding, in his simple expansion designs of
the “Precedent” class 2-4-0 and “Cauliflower” goods 0-6-0’s there appeared successful designs of locomotive unsurpassed by many, many others. A great number of the latter survived nearly a century, passing into the hands of British Railways. But it was in the direction of locomotive design that his genius really let him down for not being content with developing simple expansion types that would perform the work required, he became obsessed with his pursuit of the compound locomotive. It was this principle really that consisted in costing the LNWR far more than any equivalent saving in fuel consumption. His designs, such as the “Experiment”, “John Hick” and “Dreadnought” classes were almost total failures, being both heavy on fuel and difficult to operate. Moreover, he later attempted to dispense with the idea of coupling the driving wheels together, with the result that whereas often the leading wheel could be seen turning in one direction, the trailing wheel would revolve in the opposite direction!

Despite this handicap in the motive power department the LNWR’s train services provided a level of punctuality second to none, smoothness and comfort in travelling too were unmatched, for a time at least, by any other company. In appearance, the ”Blackberry Black” of its locomotives, with their complex lining in red, cream, pale blue and grey made a pleasant, and in some of the grimier industrial areas, outstanding contrast with the “Purple Brown” and white coaches.

Train speeds of the late Victorian period were not, on the whole, high, but certainly comparable with those of other railways. The crack Anglo-Scotch express, was the 2-0 pm “Corridor” from Euston, even so, it took some eight hours to reach the Scottish border from the Capital. Indeed, just prior to the famed ”Race to the North” of the late 80’s and 90’s, Edinburgh was reached in around ten hours of travelling – an interesting comparison with the 4.5 to 5 hours of today’s “Pendolinos”. These timings are roughly comparable to the speeds achieved soon after the Euston to Glasgow electrification was completed in 1974.  For the LNWR’s premier services, around 120 years ago, “slow”, would not perhaps be the right word – sedate would fit the bill much mare precisely.

Classic LNWR – and one of George Whale’s first designs after taking over as CME. The “Experiment” class 4-6-0 were built between 1905 and 1910. This class 0f 105 locomotives was intended to carry the ‘Scotch Expresses’ over the formidable Lancaster to Carlisle route, with the ascent of Shap to contend with.                           Photo (c) Lens of Sutton / R.P. Bradley Collection

Following the turn of the century, the first two decades saw yet another interesting period in the LNWR’s history, and one of considerable change. This relatively short period saw three changes of C.M.E., taking the Company up to amalgamation with the Lancashire & Yorkshire Railway in 1922, before finally merging into the LMSR on 1st January 1923. Train timings were improved somewhat after 1900, although by today’s standards, still sedate, with average speeds in the order of 55 mph for express trains. Passenger loadings were constantly increasing hence also the trailing tonnages hauled by the locomotives. It should be pointed out though, whilst we are now accustomed to reading accounts of performance with train weights cited in tons, in LNWR days it was customary for the guard to inform the driver that he had ”Eight equivalent to sixteen on”. This in effect was to say that there were eight bogie coaches behind the engine, each of which, by tradition was reckoned to be of equivalent weight to two standard four-wheelers.

The practice of quoting grain weights in terms of vehicle numbers continued for some time. Not so for the Webb compounds though, for no sooner had George Whale succeeded to the post of CME, than he embarked on a program of scrapping the three-cylinder passenger types, and modifying the 4-cylinder goods locomotives. The LNWR was desperately in need of efficient, powerful and simple, above all simple, locomotives. To this end, Whale saved the day, surprisingly quickly too, by all accounts the drawings for the ”Precursor” class 4-4-0 were prepared in March 1904 and quantity production was in full swing by September of that year. Whale also produced the “Experiment” class 4-6-0, a larger version of the “Precursor”. In fact, it has been said that both of these designs were developed from Webb’s own ”Precedent” class 2-4-0. Perhaps the last, and in some ways most outstanding LNWR locomotive type was produced under the guidance of C.J. Bowen-Cooke in 1913, the 4-cylinder 4-6-0’s of the “Claughton” class. This locomotive was the result of a series of comparative tests on the LNWR of a
 Great Western “Star” class 4-6-0, though in appearance, the “Claughton” was unequivocally a product of Crewe. The later products of the LNWR from Crewe, from various CME’s of the early Twentieth Century, were entirely successful in their work. The “Claughtons” particularly, for in fact it was on this design that the LMSR based its ”Baby Scot” or “Patriot” class 4-6-0s, some of which were “Claughton” chassis with LMS designed superstructures.

ClaughtonThe days following the 1914-18 war were something of a period of “marking time” for the LNWR, and Crewe Works, having been fully occupied with munitions work there was little prospect of recovery to pre-war levels of operation. In 1921,the Act of Parliament which sanctioned the formation of the four grouping companies, came into being, whilst the amalgamation in 1922 with the Lancashire & Yorkshire Railway was nothing more than a curtain raiser for the fun and games that beset the newly constituted LMSR in 1923. Having just emerged from a war, slightly the worse for wear; the LNWR was about to engage in another, with even greater consequences. But that, as they say, is another story.

A number of the LNWR locomotive designs lasted into the British Railways era, and even one of the “Claughton” 4-6-0s survived to be given BR No. 46004, and classed as 5XP – albeit with a new boiler fitted.  The smaller classes and freight designs from the Webb and Whale years lasted a very long time, and in 1955, the last of Webb’s 2-4-2 tank engines was withdrawn – and claimed a place in the BR London Midland Region magazine:

At the time of the 150th anniversary of the ‘Rainhill Trials’ in 1980, the LNWR was represented by another Webb Stalwart – the “Coal” tank, the last of which had been withdrawn in 1958.  Still looking good in “Blackberry Black”.

You couldn’t make it up!

Standard

Yesterday, the DfT issued a press notice asking for suggestions/volunteers to make use of redundant, soon to be removed Pacers from rail services in the north. According to the DfT’s proposals, they are launching a competition for community groups to provide ideas and plans to take one of these vehicles – no they don’t actually say if they mean a single vehicle or a 2-car set – into a new “public space”.

In their lives to date, those Pacers have indeed created public spaces, but I wonder how this “initiative” will pan out.

Any takers out there for a garden shed?

The Rail Minister (Andrew Jones) actually said this:

“The Pacers have been the workhorses of the north’s rail network, connecting communities for more than 30 years, but it is clear that they have outstayed their welcome.”

Really?!  He might have added that they have been a source of misery, complaints, discontent and overcrowding for about the same length of time.  An opinion piece in the Guardian put it rather more interestingly:

Turning Pacer trains into village halls?

The Managing Director (David Brown) of Arriva Rail North made this interesting comment too:

“Northern is introducing 101 new trains worth £500 million, the first of these new trains will be carrying customers this summer, and at the same time we will start to retire the Pacer trains. Using a Pacer as a valued community space is a very fitting way to commemorate the service they have provided since they entered service a generation ago.”

Ironically, just a short while before the Metro Mayors of Greater Manchester and Merseyside both called for Northern to have its franchise terminated immediately.  According to a report in the Guardian today (29th May), both Andy Burnham and Steve Rotherham believe:

” ….has consistently failed to show it is able to take the action required to restore public confidence or deliver its legally-binding franchise requirements …”” ….has consistently failed to show it is able to take the action required to restore public confidence or deliver its legally-binding franchise requirements …”

It is perhaps ironic too, that the first of the “Pacers” were out to work 34 years ago in May 1985, in the Greater Manchester area, although as is common knowledge, a number of prototypes were built before a major order was placed. Officially, they were described as lightweight diesel multiple units, developed for use on lightly loaded and suburban services.

The first days went reasonably well – apart from the ‘blacking’ by the rail unions of a later design – but quite soon after their introduction they ran into some operational challenges.  They were also used after privatisation on longer distance workings, including one between Middlesborough and Carlisle – a distance of over 100 miles, and well out of their intended working.  When these twin-units were sent to the south west, they were nicknamed “Skippers”, and reportedly ran into difficulties keeping to time on the South Devon banks.

RPBRLY-12 copyWhilst the entire fleet had their Leyland engines replaced by a Cummins design in the 1990s, some ‘refurbishment’ was carried out on each of the classes, from Class 142 to Class 144.  The original prototype was initially preserved, and BREL did try to sell this idea to various countries around the world, from the USA to Malaysia – but there were no takers.

Perhas fitting that some should be turned into garden sheds or community facilities, where people can reminisce about the good old days of travelling by “Pacer”.

Here’s a link to a piece I wrote earlier:

Paxman – Probably the Finest Diesel Engines on Rails

Standard

The firm of Davey Paxman, then Ruston Paxman, and in its final guise of GEC Diesels Ltd was established in 1865, in Colchester, Essex.  Their original product line included agricultural machinery, steam boilers, portable steam engines, and stationary engines, with a wide range of applications in mind.

It was not until just before the First World War that they took an interest in the possibility of ‘oil engines’, with some of the early designs arranged horizontally, just like the company’s steam designs.  From around 1925 they began designing and building engines in the more conventional, vertical layout.

What was to prove revolutionary in diesel traction’s use of quick-running engines, allied to innovative mechanical and ovcerall design. This view shows the very first diesel locomotive on British railways, built by the LMS, with its Paxman engine, on what was essentially a steam engine chassis.      Photo; Lens of Sutton

Only 5 years later, in 1930, as the LMS railway began its experiments with diesel rail traction, and the first diesel engine was installed in LMS prototype shunter No. 1831.  The engine was a 6-cylinder machine, developing 412hp at 750rpm, and designated type 6XVS.   The railway company constructed the mechanical portion of the locomotive, based around the frames of a steam engine, and other details, whilst the Paxman engine was the first rail traction diesel engine, installed in the first diesel locomotive on the standard gauge, for a major British railway company.

However, Paxman’s global reputation was based around quick-running ‘vee’ form diesel engines, and it began to make inroads in this area from around 1932, and with that step they were wholly successful, be it marine, stationary or rail traction.  Davey Paxman’s fortunes were assured.

The Second World War provided a pivotal platform for the technology,  and the Paxman 12TP engine – originally designed for a special assignment – was used in the British Landing Craft, and of course played a key part in the D-Day landings.  From that event 75 years ago, more than 4,000 Paxman 12TP engines were used in every assault operation carried out by Allied Forces in Europe.  This same engine design was refined for wider commercial use in the 1950s, including rail traction, and re-designated type RPH.

12RPH

The early 1950s saw the introduction of the YH range, direct fuel injection, and 4-valve cylinder heads.  The refinements of these designs, with ease of maintenance, provided an ideal platform for railway locomotives, with many examples used in branch line, shuntin, and in later develoipments for main line operations.  The quick-running 4-stroke diesel had certainly come of age.  By the end of the decade, a further development of these engines appeared in the shape of the “Ventura” range.

Paxman images 8 copyThe latest design was developed to meet the requirements set by British Railways, building on the design and construction of the RPL and YH engines, incorporating advanced engineering features, and competing with the best European builders were offering.  In fact, these engines were built under licence by Breda for Italian State Railways’ Class 343 locomotives, whilst further east in Ceylon (present day Sri Lanka), “Ventura” engines were fitted to a fleet of diesel hydraulic locomotives for shunter/trip and main line duties.

Paxman images 3 copyOn British Railways, the first of these new engines were fitted and trialled in one of the Western Region’s Swindon built “Warship” Class diesel-hydraulic locos – No. D830 ‘Majestic.  The “Ventura” engines were also retro-fitted to 20 of the North British Bo-Bo diesel-electrics, developing 1,350-hp at 1,500 rev/min engines, following the disappointing service experience with the locomotives’ original power units.  

D6123 from Paxman booklet

One of the NBL built Type 2 engines after refitting with Paxman engines proved much more successful.

Another order from British Railways, was for power unist for the last diesel-hydraulic type used on the Western Region – the Class 14 0-6-0 – together with 6-cylinder versions for the Southern Region’s “Electro-Diesels”.

Class 14 – The last Main Line Diesel Hydraulics

The experience with the “Ventura” design also provided background for the next step in the development of the Paxman range.  Paxmans’ working with British Railways and the MOD (Royal Navy), a new range of high-speed diesels, in the shape of the “Valenta” series were created.  These new engines were the same size and shape as the “Ventura”, but although of the same bore and stroke, gave 40% – 50% more horsepower.

The heart of high-speed, the Paxman Valenta engine. Powerful and efficient too – a good combination for rail traction use.

It was these engines that were fitted to the HST, IC125, high speed trains that provided the mainstay for British Rail’s express passenger services for more than 45 years.  Some are of course still in service today.

The prototype HST was fitted with a 12 -cyl. Valenta 12 RP200L, charge-air cooled engine developing 2,250 bhp (UIC) at 1,500 rev/min.  Announced in 1970, the production sets would consist of a pair of power cars equipped with these powerful diesels at eaither end of a 7-car formation of Mark III coaches, which included two catering vehicles.  British Rail’s plan was to order 150 of these trains over a 5-year period, which it was suggested could be extended to 10 years up to 1985, starting in 1975.  They were set to work on both the London to Cardiff and London to Newcastle routes.

In their HST guise, Paxman’s “Valenta” engines were definitely at the top of the tree.  They achieved no less than three world speed records.  The first was on 12th June 1973, when the prototype reached a speed of 143.2 mph between Northallerton and Thirsk on the East Coast main line.  The second, 22 years later, when on 27th September 1985 the Tyne-Tees Pullman, with Paxman power ran from Newcastle to London King’s Cross (268 miles) in under 2 hours 20 minutes, achieving a start to stop average speed of 115.4 mph.  Finally, just two years later in 1987, with power cars 43102 and 43104, the world speed record for diesel traction was broken again.  Over a measured mile between York and Northallerton, a speed of 148 mph was recorded, with peaks at just under 150 mph.

The longevity of their success suggests that Paxman high-speed diesels were probably the finest diesel power plant designed and operated on rail.
