Last British Steam for the Raj

Standard

Over 70 years ago, the locomotive manufacturers in Britain began supplying its last main line steam locomotives for Indian Railways – steam traction was still in abundance at home and abroad, but diesel and electric traction was making rapid progress.  UK based manufacturers like English Electric and Metropolitan Vickers were early exploiters – mainly in what were then British colonies.  Prior to World War II, more than 95% of steam locomotives were built in Britain and exported to India, for use on the various railways – which were then a range of state/privately owned companies – and on top of this, with different gauges. 

During the steam era, both pre and post nationalisation, the North British Locomotive Co., in Glasgow, and Vulcan Foundry, in Newton-le-Willows, were heavily involved in the design, construction and export of steam locomotives to the Indian sub-continent. But the British builders had to contend with competition from other countries, including the USA, Canada and Europe before, during and after World War II.

New Indian Standard loco designs were developed in India, to cater for the poorer quality coal, which the previous British standards struggled with. That said, Vulcan Foundry, North British Loco and others built examples of these new designs, including some of the last for India after 1945, and the Indian Government’s rail nationalisation of 1951.

Britain secured a number of orders after the Second World War, and construction continued within India after 1951, with the opening of the Chittaranjan Locomotive Works, where many steam engines were built.

HS2 – We’re Off – Officially

Standard

This was the main transport story on the 4th September on numerous news outlets – well after the Covid-19 quarantine issues for travellers. What does it actually mean – work has been underway for some time in site clearances, groundworks in preparation to build a dedicated line for passengers from London to Birmingham.

This is what HS2 stated on its website at what was deemed the official launch day:

“HS2 Ltd has today (4 September 2020) announced the formal start of construction on the project, highlighting the large number of jobs the project will be recruiting for in the coming months and years.

So, this controversial project continues to progress, and the objections and protests continue, but will HS2 achieve its objective? Again, according to the company’s own website, this what they are seeking to achieve:

Yes, I know it is only Phase 1, and the remaining sections will take the high speed links to Manchester, Leeds, etc. But – that’s still a long way off, as indeed is the completion of the 140 miles from London, near Euston & Paddington, to Birmingham Curzon Street. Yesterday too, Solihull gave consent to the building of the Birmingham Interchange Station, with its ‘peoplemover’ link to the NEC. Wonder if that’ll be “Maglev Revisited”? (See: Worlds First Commercial Maglev System)

“HS2 is a state-of-the-art, high-speed line critical for the UK’s low carbon transport future. It will provide much-needed rail capacity across the country, and is integral to rail projects in the North and Midlands – helping rebalance the UK economy.”

See: https://www.hs2.org.uk/what-is-hs2/

That said, much has changed in the 10 years that this idea has been cooking, and some dramatic changes have ocurred in 2020, and will doubtless occur in the years to follow. But this statement that formal construction of HS2 has begun, only refers to Phase 1, and the world may well be a very different place again by 2033, when that phase is due to complete.

The official description states that the new dedicated line will rejoin the WCML north of Birmingham, and whilst the new Curzon Street station will serve the city and the West Midlands, will passengers for Glasgow use the route? HS2 do state services “…will travel onwards to places like Manchester, Glasgow, Liverpool, Preston and Wigan.”

The next phase – 2a – is to take the line from Birmingham to Crewe, and provide onward connections to the north – Manchester, Liverpool, Preston, Lancaster and Scotland. Interestingly, HS2 state that these locations will be part of the “high speed rail network” – they already are in that category, and HS2 is unlikely to make that journey any quicker.

So, does that mean that the ticket you buy to visit relatives in Carlisle will take you all the way, or will you need to change trains at Birmingham Curzon Street. If not, that’s good, and will simply require the paths for the new HS2 services to be slotted in to existing paths on the WCML to continue north to Crewe. They will also need to be mixed into the existing freight services for some time too, as Phase 2a has not yet received approval to proceed. The intended completion date has had a number of iterations for this key section, but is currently estimated to be somewhere between 2035 and 2040. So far, only the design processes and basic mapping and groundwork preliminary tasks, environmental assessment, etc. have been carried out north of Birmingham, and sadly, Covid-19 has paused the final approvals through Parliament this year.

For phase 2a we are still a long way off starting work, and completion is at least 20 years into the future – there is perhaps a lot of uncertainty about it happening fully. Then there is the question of train operations – and perhaps whether people will choose to travel on HS2, or just take the existing trains from London Euston to the north and Scotland.

Maybe we will get to see the trains run by Italian State Railways – maybe a bit like the ‘Frecciarossa’ trains they already run in Italy – FS did start bidding to run the HS2 trains back in 2017. As is well known, they now operate the UK’s West Coast Main Line high-speed services, so at least they have experience, but who else would be on the operator short list – France, Germany, or maybe China?

In late 2017, it was announced that “Five Train Builders” had made the short list to bid for the £2.75 billion contract, which were expected to receive the award in 2019. The builders in the frame at the time were:

  • Alstom;
  • Bombardier Transportation;
  • Hitachi Rail Europe;
  • Patentes Talgo S.L.U;
  • Siemens 

Then in 2019, CAF put in an appearance, and like Hitachi, they too have a new UK base, at Newport, and currently manufacture the latest multiple unit stock used on Northern, West Midlands, and Wales & Borders. So, they have offered a train based on their “Oaris” platform. And then we had six, but thrown back to five, as Alstom have now bought Bombardier.

Mind you, HS2’s plans to award a contract in 2020 were challenged – as indeed everything on the planet has – by the pandemic that began at the start of the year. Of course, all of this will affect the opening and start date of operations on HS2 Phase 1, and perhaps even more dramatic changes will take place in the coming months, and the other phases may not come to full fruition.

The rail industry is indeed the most environmentally friendly transport sector, but although travelling as a passenger at high speed in the UK may be nice – once again iut is too little, and too late. The national infrastructure should be focussed on the movement of goods and address the growing need for more regional, and localised freight handling facilities.

A case of back to the future for freight – it remains to be seen if people really do want to travel from Birmingham to London 40 minutes quicker in 2035. In fact, in January 2020, a survey (“the post-election future of HS2”) published in “The Engineer” resulted in 52% of those polled being in favour of cancelling the project altogether.

But on the day construction of the line was formally begun, Transport Secretary Grant Shapps was quick to justify the project, and deny that the Corona Virus Pandemic had made any difference to the perceived need, he said this on BBC Radio 4’s “Today Programme”:

“We’re not building this for what happens over the next couple of years or even the next 10 years.  We’re building this – as with the west coast and east coast main lines – for 150 years and still going strong.  So I think the idea that – unless we work out a way of teletransporting people – that we won’t want a system to get people around the country… is wrong.”

Time will tell – we only have to wait another 20 years to find out.

British Railways First Locomotive Liveries

Standard

Following nationalisation, new and repainted locomotives continued to appear in traffic bearing the initials of their former owners, though replaced very quickly by a complete absence of any titling. This early period saw also a number of new engines built to the designs of their former owners, outshopped with their original works/builders’ plates fitted, but with the tell tale signs of having had the initials LNER, LMS, &c., removed before the locomotive went into traffic. The appearance of evidence of former ownership was very long lasting in some cases, with ‘sightings’ of a faded ‘GWR’, or ‘LMS’ being noted in the contemporary railway press of the late 1950s.

The full title BRITISH RAILWAYS was carried by many locomotives and numerous classes, lasting, at least officially, until the arrival in 1949 of the lion and wheel emblem, or totem as it was known.  The style of lettering adopted officially in 1949 was Gill-Sans, and had been widely used on the London Midland, Eastern, North Eastern, Scottish, and Southern Regions of BR, from 1948, although the Western Region perpetuated for a time the style of the old GWR, and some examples of former SR style on the newly formed Southern Region could also be found.

An exhibition of experimental colour schemes was held at Addison Road station in January 1948 involving a number of newly built LMR Class 5MT 4-6-0s (See Table). The first locomotive turned out with any indication of its new ownership was the WR 4-6-0 No.4946 Moseley Hall repainted in full GWR livery, but with the tender lettered BRITISH RAILWAYS using the old GWR style letters.

LMR Class 5 LiveriesOf course, it was not just locomotives that were exhibited at Addison Road, rolling stock too was displayed, with a selection of new colours, covering express passenger, suburban, and the few multiple unit types around at that time. During the first six months of 1948, the Railway Executive was concentrating equally as hard on the new image of British Railways, as with homogenising the administrative and operating procedures of the former owners.

Officially, the six regions of British Railways were colour coded from 1st May 1948, and the colours applied across most of the range of railway activity, from posters and timetables to station nameboards.

But, locomotives and rolling stock were excluded from this level of uniformity.

BR Regional colours 1948

The BTC published a series of Temporary Painting Schedules for its inhgerited motive power in late 1948 covering these experimental liveries:

1949 Liveries Table

Some of the first applications of the experimental locomotive colours were combined with similarly repainted rolling stock, and no less than 14 trains were dispatched over various routes around the country, and the public invited to comment on the new schemes. To what extent the public responded to the request is not known, and sadly, no official records of the ‘experimental’ colours now exist, other than the temporary painting schedules.The shades displayed by the locomotives came in for much retrospective comment, often incorrectly.

1949 Loco Liveries

BR’s first standard locomotive liveries, adopted from 1949 onwards. Later regional variations included some interesting changes for the Class8P passenger types in particular.

The 1948 trials brought LMS Class 5s, and GWR Kings and Castles in lined light green and lined blue, with incorrect suggestions that two different blues were used.  The appearance of the experimental colours was directly affected by the materials used. With both oleo resinous and synthetic paints applied, the latter as an alternative for the green and lined black styles, there would be perhaps appear to be differences in the colours themselves.

A4 Sir Charles Newton at York in 1950

Grelsey’s A4s certainly suited that express passenger blue – here 60005 “Sir Charles Newton” is captured at York in 1950.           Photographer unknown.

Painting of locomotives could be divided into two principal stages: Preparatory Work and Finishing Processes.

Preparatory work on complete repaints comprised a number of operations: first, a coat of primer was applied, followed by whatever stopping and filling was necessary, whilst the intermediate operations were a combination of rubbing down and undercoating. Lastly, a single coat of grey undercoat was applied, prior to the finishing processes.

The Finishing Processes took no less than three days, on the first day a single coat of sealer/undercoat was applied in the livery colour, followed by a coat of enamel/finishing paint was laid down. The second day was occupied with lining and lettering, and finally, on the third day, a coat of protective varnish was applied.

The fact that two shades of blue have been reported as ‘sightings’ in the contemporary enthusiast press could be attributed to the difference between oil based and synthetic resin paints, with the addition of extra pale varnish, or equally to the effects of cleaning. However, there was only one shade of blue, in both the experimental and early standard liveries.

Cab and side panelsLettering and numbering was also subject to variation and initially, this was affected by the regional management, and resulted for a time in the use of serif and non-serif characters, depending on whether Swindon, Brighton, or Crewe were completing the repaints. Plain white letters was the official order of the day for London Midland, whilst Swindon, independent to the last – and some would say beyond – offered its own elaborate style. But, in September 1948, the Railway Executive announced its standard instructions, whereby all letters and figures were to be in Gill Sans Medium normally be applied in gold or golden yellow, and where the outline was other than black, these letters and numbers were to be outlined in black. The statement went on to advocate not a standard size of engine cabside number, but the use of the largest possible figures that would fit in the available space.

And these were just the first steps in achieving what today would be described as the “brand image”, with the final decisions taking into account – to some degree – regional practices. The lion and wheel emblem (icon, logo or totem) was the brand that featured strongly in the years up to 1956, when it was replaced with a genuine heraldic ‘device’. Sadly, there are too few colour images of the locos carrying the early experimental liveries, and aside from the decision not to use blue for express passenger types, the 1949 standard colours were retained until the end of steam. (Yes, I well remember seeing an ex LMSR “Coronation” class pacific running through Preston in the late 1950s, but it was an exception).

RPB COLLECTION3-39

Castle Class 4-6-0 – probably 5079 “Lysander” on “The Cornishman” around 1950, complete with red & cream coaches. 5079 was previously converted to oil-burning in the late 1940s, but here seen back as a coal burner. Sadly not in colour, but it would be in standard lined green livery.             Photo: Lens of Sutton

Then from the late 1950s onwards, as diesel traction began to make its progress felt and heard, green became a favourite colour choice, and there were not a few variations there too.  The totem or logo changed in the mid 1950s too, and although often described as a crest, it was only the 1956 lion holding wheel crest was a proper heraldic device.  See “British Railways Locomotive Crests” for more details.

The liveries and styles carried by British Railways motive power in the steam era were very much suited to the motive power of the day, and provided that essential unification – and ‘brand image’ – that the nationalised railway network demanded.

Leaves on the Line : Wrong Kind of Snow

Standard

These have been the sorts of headlines that have greeted rail travellers from the mid-Autumn to early Spring, every year on Britain’s railways, and back in the days when it was just British Rail, the target for complaints and abuse was just one organisation. Today, and coming in the next 8 weeks perhaps, the same problems will doubtless occur, and delays, cancellations and complaints, along with tempers no doubt, will rise.

But, are we any further forward? The answer is yes and no – obviously!

Recently, a research paper was published identifying the tannin in leaves that mixed with the damp conditions at the railhead, and in Network Rail’s words – are “the black ice of the railway”. This in certainty will reduce friction between rail and wheel, and loss of traction. The problem, is how to remove it, and increase the adhesion levels.

This was how the media ‘broke’ the story at the end of July.

Guardian headline

Back in steam days it was, to some degree, rather more straightforward perhaps, mixing steam and sand directed at the interface ahead of the wheels as they made contact with the rail was a simple option – not infallible, but an option. Of course, that process continues to this day, as the ‘standard’ method – but improvements were and are essential.

In 2018 the University of Sheffield offered a possible solution to the leaves on the line question with an innovative idea using “dry ice”, in a trial, funded by a grant from Arriva Rail North, which led to further trials on a number of passenger lines during autumn 2019.  Working together with a Sheffield business – Ice Tech Technologies – the process was tested on little used freight lines, in sidings at depots, and later, at other locations. This is a video showing the basic elements of the process:

Fascinating, but perhaps still some way to go.

The CO2 used, is a by-product of other industrial processes, and unlike the conventional railhead cleaning and sanding, does not leave a residue on the rail head. The track cleaning trains do not have to carry 1000s of litres of water, and longer distances can be treated.

Overall the process is intended to provide improved traction and braking control.

At the heart of the challenge posed by leaves, is that layer of ‘black ice’, which in autumn and winter causes so much passenger misery and operational problems. Now, back in Sheffield, the university’s renowned skills and knowledge have identified the cause – and the answer seems to be ‘tannin’, which is present in the leaves falling from the lineside trees every year. These large molecules seems to be the key ingredient that leads to the formation of the compacted layer on the surface of the rail, providing that unwanted reduction in friction at the rail-wheel interface, in turn leading to traction and braking.

The railway environment provides many challenges in actually running changes as environmental conditions change over the year, but in Britain, winter especially has been the cause of many train cancellations and delays. Nowadays, the operation of trains and signalling systems are ever more dependent on security of communication – be that signalling centre to train, or track to train – and the on-board systems and traction drives are equally prone to the impact of our changeable weather.

Back in the 1980s, there was a famous, and often-repeated phrase used by a British Rail spokesman to respond to a journalist’s question about snow, train delays and cancellations. That remark: “the wrong kind of snow” was as historic as the BBC weatherman’s observation that a hurricane was not going to happen – and then it did, and Sevenoaks became Oneoak!

The “Wrong Kind of Snow” remark prompted me to write an article in Electrical Review looking at how the UK, dealt with extreme weather conditions, and compared these to how our near neighbours, in continental Europe managed these events. The full feature is as shown below – click on the image to read in full.

Wrong Kind of Snow3

Let’s hope these discoveries abojut tannins and the new techniques for keeping the rail head clean will work to better effect, and reduce the impact of leaves on the line in the coming months.

Merseyrail Trains’ Messy Graffiti

Standard

Fascinating and sad story – the new Merseyrail electrics have not even entered service, but stored at Tonbridge in Kent, they’ve already received a repaint, courtesy of local vandals.  The trains from Stadler’s Wildenrath test track in Germany had been sent to Tonbridge on their way to Merseyside, and are now having the graffiti removed at the Merseyrail Kirkdale depot.

These are the new Class 777 units, and 52 of the 4-car articulated sets were ordered back in 2017 from the Swiss manufacturer, with an option to buy another 60. The present Class 507 and 508 will all of course ultimately disappear. The first of the new trains was delivered in January, but this latest arrival has resulted in the need to spend a significant amount of money making the new trains look new.

This video shows some shots, courtesy of the Railmen of Kent Twitter feed –  https://twitter.com/RailinKent

 

Merseyrail’s network features one of the oldest sections of electrified rail network in Britain, opened in May 1903, it was known as the Mersey Railway, running from Liverpool Central to Rock Ferry.  It was in fact the first steam railway to be converted to electric traction.  This was a complete electrification contract, awarded to the British Westinghouse Co. (later Metropolitan-Vickers Ltd) – although all of the electrical equipment was imported from Westinghouse USA.  British Westinghouse was set up in 1899 on the Trafford Park estate in Manchester by George Westinghouse, hopin g to continue to expand the electric railway and tramway markets in the UK.

 

 

The other early component of Merseyrail was the Lancashire & Yorkshire Railway Co.’s line from Liverpool Exchange to Southport, with the section from Exchange to Crossens (just north of Southport) opened in 1904, and on to Aintree in 1906, and then Ormskirk in 1913.  As with the Mersey Railway, 600V d.c. was the preferred supply, via the conductor rail, and the same supplier.  Also, as with the Wirral line, the railway had its own power station, based at Formby, and the generating equipment was also supplied by British Westinghouse.

New Merseyrail with original

The leading coach is one of the 1920s build from Metro-Vick, but still coupled to three of the original 1903 cars of Westinghouse USA design

Over the years, the network has been expanded, and with some of the most extensive work taking place long after World War 2, in the 1970s, and in effect creating “Merseyrail”, which used variants of the British Rail designs of 3rd rail trains. The Class 507s and 508s, which provide services today were refurbished by Alstom between 2002 and 2005, but the new Class 777s provide and implement some of the latest thinking for suburban and commuter train designs.

Such a shame that delivery of these latest sets have been marred by such mindless vandalism. I know, all trains – condemned or just stabled at the end of the working day – have been subject to the works of amateur Banksy’s, but this incident even made it to the BBC’s news services:

BBC News story image

Still, once they have been cleaned up and restored to new at Kirkdale, Merseyside will have some superb new trains to travel on – from Ormskirk and Southport, to Birkenhead and Rock Ferry. Still electric after 117 years.

This video shows the new trains arriving on Merseyside, and on Merseyrail lines for the first time in January 2020:

Going Greener with Hybrid Diesels

Standard

In Ireland, the new CIE Class 22000 now features a hybrid drive, from a Rolls Royce-MTU diesel engine and Li-ion battery pack.   The principle is not new, and the Class 22000 have been around for the best part of a decade, but this latest development further enhances the railway’s green credentials.

CIE have a 10-year strategy for investment in ever more sustainable rail transport, and back in October 2019, the Government approved an order worth €150 million for 41 new “22000 Class” railcars/multiple units, on top of the current 234 car fleet. The new rolling stock will enter service in late 2021 in the Greater Dublin area, and according to CIE, will provide a 34% increase in capacity on peak commuter services.

The 22000 Class vehicles began operations in 2007, and were paired with the MTU diesel engine and Voith transmission, and were intended primarily for the Dublin – Belfast services. Between 2008 and 2011, their range of operations was extended; more vehicles were purchased, and operated as 3-car, 4-car and 5-car sets.

1080px-Drogheda_1

The classic 22000 Class dmu entering Drogheda station on 10th August 2015.  By 2011, Hyundai Rotem had supplied 63 of these, originally operated as 3 or 6-car units, later changes to 3, 4, 5, or 6 car sets provided more operational flexibility.   Diesel power was provided by the MTU 6H, 6 cylinder engine.                                                                                                         Photo:  Milepost98 – Own work, CC BY-SA 4.0, https://commons.wikimedia.org/w/index.php?curid=50261722

 

This latest order for the hybrid variety is actually part of a longer term plan to operate up to 600 battery-electric hybrid carriages on the network by around 2029. These railcars have been operating for around 12 years now, although not without some operational issues.

As ever with railways in the 21st century, buying new trains, or even power trains, is an increasingly complex process. The latest order was placed in concert with Porterbrook Leasing, who also bought the new MTU-Rolls Royce hybrid power pack, which was unveiled at Innotrans in Berlin some 4 years ago.

Rolls-Royce_MTU-Hybrid-PowerPack_

Rolls Royce MTU Hybrid Power Pack

For CIE, the hybrid power pack marks the start of much greener rail operations, and follows the path that many other national railways have started on, and whilst initially the new trains will primarily used the MTU diesel engine, too is one of the most environmentally friendly in its class. The option to link to the batteries, which are recharged during braking, will soon be the commonplace driving mode – initial starts on electric motors, then following on with the diesel that complies with EU Stage V emissions, and as the train slows, the charge used by the batteries is replenished.

But this video is a great explanation of the concept and operation.

This is a rough translation of the text with this video:

“With its Hybrid PowerPack®, MTU has been nominated for the 2018/19 innovation award by Privatbahn magazine in the Energy & Environment category. The award ceremony will take place on April 2, 2019 as part of the Hannover Messe.

The MTU Hybrid PowerPack® was developed further from the previous MTU underfloor drives. The hybrid concept consists of a modular system with various drive elements. The power-tight electrical machine is individually scalable and extremely compact. Depending on requirements, the MTU EnergyPack (scalable energy storage) can be positioned in the roof or under floor area of the railcar. This enables flexibility to procure new vehicles or to convert existing vehicles.”

MTU-Rolls Royce and CIE announced the arrival of the new Class 22000 trains with this press release:

Wellington to Paekakariki

Standard

The Wellington Suburban Electrification

Well, not strictly suburban, but the second major electrification on New Zealand’s railway lines that involved English Electric; this time on the main line linking the capital, Wellington, with Auckland, 400 miles away to the north. This was the first stage in electrifying the North Island Main Trunk (NIMT), across some of the world’s most spectacular, and challenging terrain.

ED102 nlnzimage copy

This is an image of the first of the class built in New Zealand – No. 102 is seen here in 1938 ex-works, without the skirt applied to the very first of the class, built in Preston.                               Photo Courtesy: Ref: APG-0320-1/2-G. Alexander Turnbull Library, Wellington, New Zealand. /records/22545501

 

English Electric were pioneers of electric traction, and were especially successful around the world, notably of course in former British colonies, whether India, Australia, and of course, New Zealand.  In the 1930s, increasing traffic around Wellington, and the success of the Arthur’s Pass project almost a decade earlier, the North Island electrification work led to an order for tnew main line electric locomotives.  These were the first heavyweight (my italics) locos in service on the route from Wellington to Paekakariki, which later became the North Island Main Trunk (NIMT).

At the same time, the fortmer Dick, Kerr Works of English Electric received an order for multiple units to provide faster, more efficient suburban passenger services.

The locomotives introduced a number of new, novel features, even by the emerging ‘new technology’ of the day, and yet oddly, their wheel arrangement was initially described as that of a steam loco – i.e. a 2-8-4 – but later a 1-Do-2.  It’s hard to know which sounds more compex.

The locos had a long life, and although only two survived to be preserved as static exhibits, they marked at least the start of electric traction progress in New Zealand.  The Preston company received further orders from ‘down under’ after the Second World War too, with a Bo-Bo-Bo design in the 1950s, as the “Ew” class, and as late as the 1980s English Electric – as GEC Traction – were still supplying electrical equipment.

Hopefully the overview of this design will whet your appetite further.

Updated Camels & Camelbacks

Standard

Just in case you missed a post, from a year or two back, the innovative design and use of “Camelback Locomotives” – a style that was very popular on US railroads for many years.

The heading image is from the ‘Locomotive Dictionary 1916′  and shows one of the superb “Atlantic Type” 3-cylinder simple locomotives built and operated by the Philadelphia & Reading company, for passenger service.  Many thousands of “Camelbacks”, also known as “Mother Hubbards” were built by over 30 railroads, but it is the design of the firebox that is key to its success.

(1907) The Boys’ Book of Locomotives, London: E. Grant Richards,  Public Domain, https://commons.wikimedia.org/w/index.php?curid=10548075 

There were two different types of locomotive with a centre cab, on top of the boiler – the earlier design built by Ross Winans in the 1840s, were simply known as “Camels”, but the later design with a new, and innovative design of firebox.  This also appeared initially on the Philadelphia and Reading Railroad, with the wide grate of the “Wooten Firebox”  its key component.  The design was patented by John Wooten in 1877.

I’m afraid an error crept into the original post, but I am grateful to one of my readers Jim Hansen for identifying this, and as you can see the original post has now been updated.

CLASS 47 – ALMOST 60

Standard

In 2022, BR’s most common – take that whichever way you like – diesel locomotive that started life in 1962, as the first of the 2nd generation of main line diesel-electric locomotives.  It came at a time when there was certainly competition between Britain’s locomotive manufacturers, and a fair degree of collaboration and partnership within the railway industry.  There was a considerable degree of collaboration between the private/commercial sector and the BR workshops, which only declined in the 1980s, until it almost completely disappeared by the turn of the century.

So, the Class 47 – which to be precise, was announced in the railway press as a new, highly innovative design from Hawker Siddeley – who had only recently become owners of Brush Traction Ltd and Brush Electrical machines.

Brush’s prototype “Falcon” was the model for the Brush Type 4, but with a completely different power plant.

The most widely used, most well known, longest surviving, successful – just some of the words you might use to describe the Brush Traction design ordered by British Railways in the early 1960s. Successful was not at one time a word you would have used to describe this locomotive – a bulk order, rushed through as BR’s debts were climbing, and the ‘Pilot Scheme’ diesels were still “on trial”. Brush too, was perhaps an unlikely choice as supplier, since the company did not have the same pedigree as English Electric, AEI, Birmingham RC&W Co., or Metropolitan-Vickers in the railway field. But, as Dylan said, the times they were “a-changin”.

The PDF file below, is not intended to be a fully detailed account, there are several other, very well written books and articles that cover the individual locomotives, and its design and operational history in detail.

Halls of Fame – A Mixed Traffic Masterpiece

Standard

Some might say, that the Great Western Railway’s “Hall” and “Modified Hall” class 4-6-0s were simply a do anything, go anywhere mixed traffic design – which they were – but of course, the GWR would not be able to operate without them. These locomotives were the unsung heroes of the steam railway, and yet not one was set aside for inclusion in the UK’s “National Collection”. Happily though a number of both the original Hall and Modified Hall designs can still be seen in operation, and under restoration. In fact, one of their number is being ‘re-modified’ to represent the precursor Churchward “Saint Class”, which is a tribute to the design’s longevity and importance.

This class of 4-6-0 was easily the most numerous on the GWR., and was a design whose ancestry can be directly traced to the famous Saint Class. In a number of instances they have been referred to as “6ft 0ins Saints”. No fewer than 258 of Collett’s new Hall Class engines were built between 1928 and 1943, following the highly successful modification and operation of saint class engine No. 2925 “Saint Martin”.

Designs for the new Hall Class locomotives were born out of Churchward’s practice, with some influence from the operating department.
They were perhaps the first truly mixed traffic type owned and operated by the GWR and although built when C.B. Collett was Chief Mechanical Engineer, the basic format had already been outlined by Churchward in his scheme of 1901. The success of the 43XX moguls would, in the opinion of’ the running department, be improved still further with the lengthening of the wheelbase and the provision of a leading bogie, and for greater power, a GWR Standard No. 1 boiler.

In December 1924, came off Swindon Works with 6ft 0ins coupled wheels, and the Collett side window cab. But, these were 
the most obvious differences, with others that were thought necessary on the rebuild but not included later, or modified for the production series engines.

The rebuilding of’ “Saint Martin” incorporated standard ‘Saint Class’ cylinders, which following conventional Swindon practice, required them to be carried lower in the frames, in order to line up with the centre line of the smaller coupled wheels.

So, that’s where the new “Hall Class” started life, as a combination of an earlier 4-6-0 design, paired with the operating ideas and experience with the 2-6-0 “43XX Class” moguls.

The New Kid On The Block

The appearance of’ the new mixed traffic engines was not without its troubles, despite the successful trials with the rebuilt “Saint Martin”, though fortunately, none of these related to the design, construction, 
or operation of the new engines. On the GWR, as on other companies’ lines,
 the 1930s was a time when many of the older designs were being scrapped and replaced with more modern, more efficient designs. However, the rail enthusiasts of that time regretted the arrival of the “Hall Class” only because many of the ageing 4-4-0s – some dating back to 1890s – would soon be extinct.

The first 80 of the new breed of locomotives came out of Swindon Works under Lot 254, between December 1928 and February 1930.

The first of the many – No. 4901 in photographic grey at Swindon Works in 1928. This was a very successful design, and formed the backbone of GWR and BR Western Region mixed traffic working until it was scrapped in 1960.           (c) Historical Railway Images

Unsurprisingly they were fitted with the Swindon Standard No.1 boiler, as adopted for all large 10-wheeled locos, and fitted to their predecessor “Saint Class” 4-6-0s, but with Collett now in charge, the footplate crew were provided with a larger, side window cab. On the face of it this might not seem a key design improvement, but compare the Hall cab to an older design, such as the Saints, with their Churchward cab, the protection from the elements was visibly improved.

In construction, the new design largely kept to Swindon practices, whether it was for boiler, firebox, frames, or bogie design, with the Collett changes having been proven in practice with the highly successful “Saint Martin” – rebuilt and delivered in December 1924. In fact this rebuild was so successful that an order for those first 80 “Hall Class” was placed with Swindon Works in December 1927.

Eventually, 257 of the “Hall Class” were built up until the early spring of 1943, and cost £4,375 each  in the first batch, and whilst subsequently, cost rose, they rapidly became the GWR’s workhorse, and universally operated across the network.

Boiler, Frames, Wheels and Motion

These were the Swindon “Standard No.1”, and were fitted to all the GWR’s 10-wheeled locos, and were the same as those fitted to the “Saint Class”, but the Halls boilers had the added suffix ‘A’, as prescribed in the company’s extensive classification scheme. The boilers were built in two rings, with the second ring tapered, attached at the rear to a trapezoidal shaped firebox, following ‘Belpaire’ style, and “waisted in” to fit between the frames at the cab end. The firegrate itself had a flat rear portion, with the front tapering downwards, from just in front of the training coupled axle.

The cylinders were mounted on the outside of the frames, as part of a casting with half of the smokebox saddle. The inside admission piston valves were carried above the cylinders, and a rocking shaft transferred the movement through the frames from an extension rod, expansion link, and the eccentric rods attached to the driving axle. Sounds complicated! Eccentrics mounted on the driving axle were the characteristics of the Stephenson valve gear, which, by the 1920s was standard Swindon practice.

The 6ft 0ins coupled wheels had 20 spokes, and were paired with 3ft 0ins diameter wheels on the leading bogie. Churchward’s simple design principles in the generously proportioned axleboxes, with pressed in whitemetal liners were maintained by Collett – for the Hall Class these were 10ins long and 8 ¾ ins in diameter. Coupled wheels were balanced in pairs, with steel plates rivetted to the spokes, and molten lead poured into the gap, and was a change from earlier practice, and claimed to provide greater accuracy in balancing.

That same simple design approach was equally effective in the coupling rods, which were plain, or slab sided, with no fluting – a practice adopted on many railways, ostensibly to save weight and reduce hammer blow.

Tenders

No less than three different designs of tender were paired with the class. From No. 4901 to 4942, a standard Churchward 3,500 gallon design was used, whilst from 4943 to 4957, a new Collett design of 3,500 gallon capacity was used, and finally a new 4,000 gallon Collett tender for the rest. This last type still carried the characteristic out turn to the upper sides of the bunker space, but when Hawksworth took over from 1941, this changed, and with the new ‘Modified Hall’ and ‘County’ class 4-6-0s, a simple, slab sided tender was adopted. That old simplicity rule appearing again.

Hawksworth’s Modified Hall

This was a fair bit more than modifications, and demanded changes to jigs, tools and working practices at Swindon, and so perhaps to describe this as a modification was wrong. It was much more of a development, by applying Hawksworth’s ideas to Churchward design and building a new mixed traffic locomotive for the GWR.

Hawksworth too over from C.B. Collett in 1941, and oversaw the motive power of the GWR until nationalisation in 1948. But, where Collett had largely continued the Churchward model, Hawksworth took a more radical – with a small ‘r’ – approach. He had up until that point been the company’s Chief Draughtsman, with responsibility for locomotive testing.

First out of the blocks was the 6959 Class or “Modified Hall”. These 71 locomotives were built between 1944 and 1950, and based on the Hall Class, a number of experimental ideas included that improved the performance of the 6ft 4-6-0s across its operational range.

A key change in the design of the Standard No.1 boiler used on these engines, was the fitting of a 3-row superheater, with 21 flues, which was intended to improve the speed and performance of the type, along with further boiler/firebox changes to cope with poorer quality coal. Mechanically too, the Modified Halls were a simpler construction, with full length frames, and cylinders attached to the outside faces, instead of the previous casting, which included a part of the smokebox saddle. These changes inevitably brought down building costs, and the simpler layout reduced operating and maintenance costs.

The adoption of a single mainframe construction, from drag box to buffer beam demanded a major change to the fabrication, and assembly, of the cylinders and valves. This simple change away from part plate and part bar frame to all plate frame was a radical step, and which must have caused major changes in the practices used in the works foundry and erecting shops. The cylinders, still driving the Stephenson valve motion by means of rocking shaft, were also still 18 ½ ins by 30ins, but were now cast as two separate pieces, bolted to the outer, machines faces of the mainframes. To carry the smokebox, a new cross stretcher was placed between the frames, and extended upwards to provide a support and mounting for the smokebox itself.

Modified Hall diagram

All GWR two-cylinder engines had a pronounced fore and aft motion, especially when starting, and the Modified Hall was no different, and whilst their were inconsistencies in the layout of the steam and exhaust pipes at the front, that pronounced motion continued. But, perhaps the most obvious departure was the widescale adoption of mechanical lubrication. Up to the arrival of these locomotives, GWR practice was “hydrostatic lubrication”, which consisted of the driver counting the number of drops (15 drops every 2 minutes) of oil passing through a sight glass on the footplate. The new locomotives had the mechanical lubricators mounted on the running boards, just ahead of the leading coupled wheels, and for guidance, the cab gauges included an ‘oil’ / ‘no oil’ indicator.

The tenders on the first 14 of the modified class were straightforward Collett 4,000 gallon types, but from 6974 onwards, Hawksworth provided the new, much simpler to build, slab sided design. The approach here followed that of other railway companies, in pursuing a simpler design and build process, to reduce capital and operational costs, with the intent that maintenance practices would be cheaper.

Oil Burners

The use of fuel oil for railway locomotives at the time the Hall Class arrived was not in regular use in Britain, because of the abundance of coal supplies – and no doubt the cheap cost of mining.   Even so, it had been tried back in 1893, with the most famous examples being on the Great Eastern Railway – as an experiment.

Shortly after the end of World War 2, there was a coal shortage GWR, and in particular in 1946/47, where the severe winter drove increased demand. But, of course, there was a manpower shortage as well, despite the ‘Bevin Boys’, who were recruited to replace the young miners, who had been conscripted during the early war years.

So, the railways, including the GWR, revisited the idea of equipping steam locomotives for burning fuel oil. This was also encouraged by the promised removal of the fuel-oil tax, and in October 1946 a subsidy of £1 per ton was paid to consumers – such as a railway – of fuel oil. This subsidy offset the fuel-oil tax, and with that in mind the GWR planned to convert 84 Hall Class engines to oil burning, but in the end only 11 were completed, with another 10 fitted with the oil burning equipment. In addition, the Government promised help to all companies changing over from coal to oil, which included the bulk purchase of all the necessary equipment, both on the loco and on the shed.

Converted

So, for the GWR, the first loco to be converted was No. 5955 “Garth Hall” in June 1946, and it was allocated a new number – 3950. The remaining 10 locomotives were converted in April and May 1947, and included: 4907/48/68/71/72, 5976/86, 6949/53/57. The average life of these locos as oil burners, was around 2 years, with all being reconverted to oil-burning in 1950.

By 1950, the few Hall class engines that had been running as oil-burners, were all converted back to coal burning. In this view, the original candidate “Garth Hall” is paired with a standard Hawksworth 4,000 gallon tender.

Operations

So, why were these locomotives needed? They were introduced at a time when the GWR had few modern mixed traffic designs, but plenty of the express passenger variety, and whilst Churchward’s application of new developments, especially following French practices were a great improvement on the Dean era, traffic was changing. Churchward had already introduced the 47XX series of heavy freight 2-8-0s, but a design that could be used on both passenger – long distance, or shorter – and a variety of freight workings was becoming an essential tool in railway operations.

When the Halls started to appear, all of the ‘Big Four’ companies were engaged on modernising and standardising their locomotive stock, which, in the 1930s resulted in many hundreds of the old ‘pre-grouping’ designs being scrapped, and replaced by engines with a wider operational range.

On the GWR, Churchward’s approach to locomotive design and standardisation in 1901 was mirrored in later years, by British Railways from 1948, and included elements of current best practice at home and abroad. Tapered boilers for example were introduced after studying the American approach, whilst the firebox was developed from a design popularised in Belgium, by Belpaire.

Churchward’s successor C.B. Collett applied these radical changes introduced a decade or so earlier in the “Saint Class” conversion in 1924, and delivered the most successful mixed traffic design the GWR operated, as the “Hall Class” 4-6-0.

The earlier ‘standard designs’ had included a mixed traffic loco with 5ft 8ins coupled wheels, and was a type that had been advocated by the Operating Department. The Hall experiment – which you could conclude was an exercise in recycling, delayed the introduction of a 5ft 8ins mixed traffic engine, and was entirely down to the Hall’s operating success. Collett did finally introduce a 5ft 8ins mixed traffic design – the “Grange” class, from 1936, more than a decade later.

Initially, the first 14 Halls were sent out to the West Country and based at Laira and Penzance, but as more were built, they were soon spread out across the network, and by 1947; some 30 depots had an allocation of the Hall Class.  From their earliest days, workings normally associated with Halls were as varied as the names they carried, from freight, empty stock, stopping and express passenger. Only the prestigious ‘Cornish Riviera’ express was excluded from their range, but in later years, even this was overcome.

Barring engine 4941 “Bowden Hall”, which received a direct hit from a bomb in WW2, most of the class survived into BR days unscathed, and remained so until around 1961, and as dieselisation progressed rapidly on the Western Region, only 50 Hall Class engines were at work in 1965.

The Modified Halls of course suffered similar fate at the end of steam, but they had earned a reputation as speedy machines, and were well though ouf by enginemen and maintenance crews alike. The various changes to their design and construction certainly seemed to add to their value as mixed traffic designs, and coupled with their Collett progenitors, they were indeed a mixed traffic masterpiece, shared by three different CMEs of the old GWR.

After Life

Perhaps unsurprisingly, no fewer than 11 of the Hall and 6 of the Modified Hall class engines were rescued from the breakers’ torches, and now ply their trade on a number of Britain’s Heritage Railways. There are 3 Hall Class and 3 Modified Hall Class fully operational, with 4 of the Halls either being overhauled or restored, whilst 4920 is listed as stored on the South Devon Railway. Perhaps most interestingly, a Hall Class achieved superstar status thanks to Harry Potter and J.K. Rowling – 5972 “Olton Hall” is now a static exhibit at the Warner Brothers Studios.

Of the Hawksworth Modified Halls 4 are fully operational, with one being overhauled at the time of writing, and the final member 6984 “Owsden Hall” being restored at the Buckinghamshire Railway Centre.
