Diesel traction was pioneered in Britain by the LMSR in the 1930s, with a variety of shunting locomotive types, and by the late 1940s steps had been taken towards the arrival of the first diesel locomotive intended for main line work. Under the guidance of the LMSR’s C.M.E., H.G.Ivatt, and the co-operation of English Electric Ltd.,1600hp diesel-electric No.10.000 took to the rails in December 1947.
Here was the first of an entirely new breed – the 16-cylinder English Electric diesel engine operating a generator, supplying power to the six electric motors driving the road wheels of the two bogies. English Electric had long been involved with non-steam design and build, mostly for overseas railways, and were at the forefront of most development and innovation around the world.
The use of traction motor/gear drives had already replaced the jackshaft/side rod drives of the pioneer shunters, but No.10,000 was its ultimate development on the LMS. Diesel power was also the first step towards the elimination of steam locomotives as the principal source of main line motive power. But nobody looked at it that way then; it was the train of the future, something for small boys to marvel at on station platforms.
These first main line diesel types were perhaps considered along the lines of proposed ‘atomic trains’, a far-off concept in the post-war era. Strangely enough, by the time BR came to embark on its dieselisation programme, diesel locomotives had become smelly tin boxes on wheels, and the seeds of steam nostalgia were sown. It’s doubtful that steam era footplatemen were anything other than happy with improved conditions.
So much for the train of the future!

The Southern Railway too was progressing with main line diesel traction in the post-war era, but it was not to be for a further three years after nationalisation that their locomotive appeared. Meanwhile the GWR had decided as usual to pursue an independent course, with plans for gas turbine types, although these too would not be completed until 1950.
This cartoon appeared in the April 1948 issue of the railway’s “Carry On” magazine, and reflected the new technology, and its need for heavy fuel oil to power the locomotive, and not coal.
There is a new word in town – it’s “digital” – and you can use it for anything to make it sound big, clever, or a technological marvel. Take the “digital railway” for instance, what is it? This is what they said on their website in 2019:
“Digital Railway aims to deliver the benefits of digital signalling and train control more quickly than current plans, deploying proven technology in a way that maximises economic benefit to the UK.”
In 2021, this was changed slightly and now reads:
“What’s the Digital Railway programme?”
“The rail industry’s plan to transform the rail network for passengers, business and freight operators by deploying modern signalling and train control technology to increase capacity, reduce delays, enhance safety and drive down costs.”
Now, a couple of short videos are posted on the opening page:
That said, hundreds of signalboxes are now on their way into history, and the UK has come a long way from mechanical, through electro-mechanical and electronic systems, and is changing at an even faster pace today.
Chris Grayling, the then Transport Secretary, stated in 2017 he was taking £5 million from the £450 million pot for the UK’s “Digital Railway”, to enable Network Rail to investigate options for making the Manchester to Leeds route “digital”. But why Network Rail – implementing ETCS at even Level 1 will require work from the train operating companies and rolling stock owners to retrofit their locomotives and trains. On top of which, some have already been fitted with what will become non-standard TPWS, and cab signalling/driver advisory systems, which would add to the cost, although today ETCS has been used on lines in mid-Wales, and under test on the Hertford loop.
Clearly Mr Grayling – and maybe even the “Digital Railway” web pages are highlighting what they might like to see, and there is still much work to be done.
Yes – I know about the WCML upgrade work – but, although it was included in the EU “TENS” programme – I can’t help but wonder if it will be fully complete without more private investment, or ideally perhaps state investment. ETCS together with GSM-R telecoms was and remains an integral part of the ERTMS platform, which perhaps not surprisingly has progressed in fits and starts over the years.
I remember first writing about this over 20 years ago, and whilst yes, historians will say that automatic train control systems have been around on London Underground, the Great Western Railway (in steam days), and even British Railways in the 1950s, this is really about ETCS. Back in the 1990s, as Solid State Interlocking and IECCs (Integrated Electronic Control Centres) began to arrive on BR, the old fixed block systems were gradually being phased out and replaced by the new technology, which today we are obliged to call the “digital railway”.
Ironically perhaps the video on the Digital Railway website states that the UK needs a new signalling system designed for the 21st century – what a pity the UK didn’t invest sooner in the 20th century system that this Digital Railway will use. Perhaps the one thing I would take issue with in their promotional video is that this nirvana will provide “better connections” – well only if you provide more stations and more trains on new or re-opened lines perhaps!
A current version of the same video, and the “better connections” feature seen previously seems to be missing, and more attention focussed on the improved capacity, and CDAS (Connected Driver Advisory System) included.
Automatic Train Operation (ATO) still features, the ‘autopilot’ for trains, along with real time train performance information gathering – oh yes – and being able to update passengers in real time about delays. This latter presumes that stations have information displays on the platform – many still do not have this, and it seems to depend on the train operating company (TOC) to put these facilities in place. But it is progress – albeit slow.
Still we do have the experience of the Cambrian Line ETCS at Level 2 to gather data from, analyses and provide that next step. However, despite Mr Grayling’s proposition, Thameslink is next in line, along with Crossrail – and presumably Crossrail 2, which has replaced the planned work on the Transpennine electrification. The Thameslink core will be receiving in addition, a system from Hitachi that allows automated route setting, and claims to minimise signaller involvement, but does not control the interlocking directly, but responds to status information, with sophisticated software used to set or amend the route.
In 2018, details were published of the ETCS rollout projects for the remainder of Control Period 5 (CP5), which took us up to the end of 2019, and these included:
From that list – intriguingly – the ETCS deployment on Crossrail has been described as a “Metro based” signalling system, which is apparently not compatible with mainline deployment. So, here we have a “digital strategy” to deploy ETCS Level 2, but which is not being deployed in a strategic way. This is what the strategy document actually said:
“The Crossrail core section utilises Metro based signalling that is not scalable from either a technology or procurement perspective for widespread mainline applications.”
Given that Crossrail is supposed to provide a cross London route for main line trains, why would you deploy such a system? Does it provide full ETCS/ERTMS compatibility, and does calling is a “Metro based” system just mean that its name is the only thing that has changed?
More recently, the rollout of ETCS has been proposed to the East Coast Main Line, and in 2018, the “Digital Railway Strategy” indicated that this would be done in a ‘discrete’ manner, as and when signalling was due for renewal and/or replacement. Is this just a piecemeal approach? This is what was stated as the 2018 strategic approach to signalling:
So, further deployments were planned in line with funding through CP6 and CP7, and in late 2020 it was announced that £350 million was to be used to deploy “digital signalling” on the southern section of the East Coast Main Line. This is the section from King’s Cross to just north of Peterborough, and will be migrated to ETCS level 2 with no lineside signals in a phased approach. At the same time existing passenger and freight trains will be fitted with the new technology. The major changes to the infrastructure and signalling systems, including the provision and deployment of ETCS, was set to be carried out by a partnership of Network Rail, WS Atkins and Siemens in a framework contract.
With a new Transport Secretary in place – Grant Shapps replaced Chris Grayling in July 2019 – the development and rollout of the “digital railway” is still not a strategic plan, but based on business cases for the routes, and often only sections of the main routes. Much of the national rail network’s main routes will not see ETCS in either Level 1 or Level 2 form until the next two control periods have passed – sometime in the next 10 years. In fact, according to the Long Term Deployment Plan, most work on the infrastructure – based on a business case for the specific renewals, and retrofitting trains – will happen between 2028 and 2039. Presumably that depends on funding being available, and whether or not the private train operating companies – passenger and freight – buy into this evolving strategy.
Goodbye to the Signalbox
With the reliance on in-cab signalling and in formation, lineside signals will gradually reduce in importance to the operation of the train, and as innovation and technical developments take place, the control of train movements will become ever more centralised. That said, controlling traffic flow will still need to have multiple – if fewer – points of control, and changes to movements and/or direction can be implemented more rapidly with 21st century communications. This will have perhaps its greatest impact on the lineside feature that is the signalbox.
The traditional signalbox – IECCs and SSI as well? – is being replaced by the ROC (Railway Operating Centre) – which although essentially a Network Rail facility, will be a shared facility with the private train operators’ staff working alongside Network Rail at 12 locations.
So close to nationalisation surely?
Of the ROCs being rolled out by Network Rail, Manchester was first, and kitted out with the latest software and systems for train control, planning, and automated route setting, opened in July 2014 by Sir Richard Leese. In the UK this is the Hitachi platform for train management, known as“Tranista”, which was developed initially for GE Transportation Systems, but works with both Alstom MCS and Siemens Westcad
Nice, but functional, and behind the walls lies the heart of the operation, computer systems and traffic management software.
I’m guessing they’re not necessarily using Windows!
This has been a long time coming. Back in 2002 I wrote this item for ‘Engineering‘ summarising some of the platforms available, and what was being used and proposed on the UK rail network – much has changed and developed with technology, but it makes an interesting review.
For all the talk of Nigel Gresley and his exceptional express passenger types, the LNER were in dire need of a easy to build, easy to maintain and all-round workmanlike mixed traffic locomotive. This arrived with the company’s last CME – Edward Thompson – and who provided the basis for the locomotives to meet the operating departments exacting demands during and after the Second World War.
These were the 2-cylinder 4-6-0s of Class B1, or “Antelope Class”, which arrived in 1942, and quickly acquired the nickname “Bongos”. The early examples were named after Antelopes, and included Springboks, Gazelles and Waterbucks – but it was after the 6th member appeared in February 1944, and sporting the name Bongo that that name stuck, and they were affectionally forever known as “Bongos”.
They were a great success, adapting and adopting the latest ideas and techniques in design and construction, and with only two sets of outside cylinders and valve gear, were destined to give Stanier’s ubiquitous “Black Five” a run for its money as the 1940s came to an end and nationalisation took place. Thompson’s approach – in this case supported by the two main loco builders of North British Locomotive Co. and Vulcan Foundry – who built 340, with the remaining 70 from BR’s Darlington and Gorton Works – was a forerunner of the approach taken when the BR Standard classes were built.
The Thompson era on the LNER was in sharp contrast to the previous twenty years, under the guiding hand of Sir Nigel Gresley. During Gresley’s day there were a number of notable designs, and the locomotive stock was represented by a large number of different types, often designed for specific purposes, produced in response to current business and commercial demands. Gresley’s designs could almost be described as bespoke, or niche products, aimed at satisfying an immediate business need, and not providing a standard range, or designing motive power which could be used on a wide variety of services.
The services that the new B1 was intended to operate were very wide ranging, and it was achieved in practice, bearing some testimony to the soundness of the idea, and as a cost-effective locomotive design they were succesful and amongst the best of their era.
The first part of their story is outlined below, so please click on the link to read on …..
35 years ago in February 1986, UK Prime Minister Margaret Thatcher signed the Canterbury Treaty with French President Francois Miterrand, and this began the joint construction and operation of the Channel Tunnel. Equally important was the Concession Agreement, signed a month later in March 1986, which provided France Manche and the Channel Tunnel Group with the responsibility for construction and operation of the Channel Tunnel. This agreement ends in 2086.
Back in the 1990s the UK was still planning the route into London from the tunnel, to connect into the much larger European high-speed rail network as shown in this map from a BRB Report in 1993:
Today, ironically perhaps, Eurostar the passenger train operating company, are in the headlines again, with a plea to the UK Government for support, and potential collapse unless funding is made available, since passenger numbers have fallen by 95% due to the Covid-19 pandemic. Quite why Eurostar should seek government funding support in the UK is a mystery, since under PM David Cameron, the UK involvement was sold off to a financial investment group including Caisse de dépôt et placement du Québec, and Federated Hermes from Pittsburgh, USA. French national railways, SNCF retain 55% ownership, and Belgian Railways, SNCB 5%.
This was the headline in yesterday’s Guardian:
In the UK, the Eurostar services only operate to London, as previous options and recommendations to run to UK regional city hubs like Manchester and Leeds were ruled out by previous UK governments. Whilst the present health crisis remains the greatest challenge for passenger traffic, almost all rail traffic in the UK is heavily subsidised, and it is unlikely now that the UK has sold its interest in Eurostar, there will be any support forthcoming.
In Paris too, the French Government appear reluctant to provide further support, and despite its limited extent in the UK, Eurostar carried 11 million passengers in 2019, with, as is noted in the press, plans to expand cross-channel and international services further. That is obviously on hold at the moment – but could it become permanent.
Freight traffic is impacted both by the Covid-19 crisis and Brexit “teething troubles”, although it may become a greater benefit to the UK economy as a whole over time, for export and import of goods, as the changes to regulations and restrictions are implemented. Maybe we could see a return of greater volumes of freight traffic to compensate for reduced passenger traffic between Britain and Mainland Europe, but the present crisis has certainly highlighted more than one transport challenge.
The North East Corridor of the Amtrak rail network has been, and remains, the most important rail route in the USA, connecting the major cities of the Eastern Seaboard with the federal capital of Washington D.C. It has been at the forefront of the deployment of high-speed trains for decades, way back to the days of the Pennsylvania Railroad’s grand electrification work, and the use of the world famous GG1 locomotives, with Raymond Loewy’s streamlining.
When Amtrak – more precisely the National Railroad Passenger Corporation in 1971, under the ‘Railpax Act’, passenger rail services were and had been run down to a very considerable extent, and the Federal Government decided it was important to rescue the most important routes. Of greatest importance were the lines in the North East States, and the infrastructure was just not fit to provide late 20th century passenger services, and so began the NECIP – North East Corridor Improvement Project.
Back in the 1980s, high-speed rail was dominating the headlines, and by 1986, the USA had experimented with, and was developing that membership of the high-speed club, and only the UK, despite the technology, research and the ill-fated APT, was being left behind. In the USA had had in mind high-speed rail transport since 1965, when it enacted the “High Speed Ground Transportation Act” in 1965, which was a direct response to the arrival of the ‘Shinkansen’ bullet trains in Japan the previous year. There followed trials of ingenious gas-turbine trains from the United Aircraft Corporation – the UAC Turbotrains – which were in revenue earning service on NEC services between 1968 and 1976. These overlapped the formation of Amtrak, and ran in Amtrak colours for a time.
To provide improved passenger services on the NEC, in the late 1960s, Penn Central ordered and operated the Budd built “Metroliner” trains for its electrified route out of New York. These trains were sponsored by the DOT (Department of Transportation) as a “Demo Service” for high-speed inter-city working along the corridor. They were a success and led, a few later to the appearance and styling of the first “Amfleet” cars.
But, next on the high-speed agenda were the ANF-RTG “Turbotrains”, which, once again, were powered by gas turbines, with the first two fixed formation sets built and imported from France from 1973. However, these were not set to work on the NEC initially, but sent out to Chicago, where they worked services to and from the mid-west. They were based on a very successful design running on SNCF metals in France, and whilst the first 4 were direct imports, Amtrak “Americanised” the design with another 7 of the 5-car sets, to be built by Rohr Industries, and powered by the same ANF-Frangeco gas turbine. These Turbo Trains were put to use on the “Water Level Route” out of New York, and were fitted with contact shoes for 3-rail working in and out of Grand Central Terminal. These were a success – if not super fast, they were very economical, and cut oil consumption compared to the earlier designs by about 1/3.
South of New York, the Pennsylvania Railroad had electrified its main line into and out of New York back in the 1930s – and of course bought the unique and classic GG1 electric locomotives. These hauled the most prestigious passenger trains on the Pennsylvania’s lines for many years, but the dramatic collapse in passenger operations in the 1950s and 60s was a major challenge. Railroads were going bust at a rate of knots, and there were mergers that perhaps shouldn’t have been, and with railroads focussing on freight, the track and infrastructure was not good enough for high-speed passenger trains. The Government decided that something needed to be done to protect and provide passenger services in the North East, and following the examples of other countries, provide high-speed services.
The end result was the North East Corridor Improvement Project, and of course the formation of Amtrak.
Having taken on the PRR’s ‘Metroliner’ and GG1 for passenger duties under the wires, it was time to look for replacement and improvements. The first changes came by way of 6,000hp E60CP electric locomotives from General Electric, and to marry up with the ageing passenger cars, these Head End Power (HEP) units also had steam heating fitted. Mind you, so did some of the new ‘Amfleet’ cars that were converted to provide HEP in the early days.
The E60s were not a success, and their planned operational speeds of up to 120 mph was never achieved, and in part due to the suspension and transmission arrangements, together with the less than satisfactory state of the infrastructure. The E60s had their speed limits capped at 85 mph, even after suspension design changes, and were later sold off to other railroads. High-speed passenger working was not something the American railroads and the NEC in particular had any great experience with at that time, and it was playing catch up with other countries. The next high-speed proposal out of the blocks was much more successful, as Amtrak turned to Sweden and a version of its 6,000hp Bo-Bo locomotive, which, built by General Motors in the USA was nicknamed ‘Mighty Mouse’.
The imported trial locomotive was the ASEA built Rc4, and was half the weight of the General Electric E60, and more aerodynamic. It was an outstanding success on trial, and despite GE being the only US manufacture of electric locos at that time, its rival, General Motors, was licensed to built ASEA equipment, which of course made it so much simpler to introduce a modern, high-speed design to the corridor. After trials, Amtrak ordered 15 of the new AEM7 ‘Mighty Mouse’ locos from General Motors, and this was rapidly followed by another 32, bringing the class total to 47. It would be wrong to suggest they ‘revolutionised’ high-speed rail in the Northeast Corridor – but they certainly paved the way for future successes – after the $multi-million NEC Improvement Project got under way.
The fixed formation sets of the ‘Metroliner’ fleet in Amtrak service on the NEC as a high-speed option dates back to 1971, when the DOT reported its preference for IHSR-1 (Improved High-Speed Rail), with the ‘Metroliners’ as the minimum investment. These self-propelled electric trains were not a great success, and were plagued with reliability problems, and even after refurbishing in the early 1970s they proved no better than the electric locos hauling the new ‘Amfleet’ cars along the corridor.
Since electrification at the time was not being progressed further – although obscure ideas such as underground tubes, STOL/VTOL aircraft and magnetic levitation systems were discussed as high-speed options – on the rail, more gas-turbine powered trains were tried. This time, the options came from France and Canada – the old UAC ‘Turbotrains’ were very heavy on fuel, alongside their perhaps questionable performance on non-electrified section.
The new gas-turbine trials featured a French multiple unit design from ANF-Frangeco, which was already in regular use on SNCF. The two on lease from ANF were followed by an order for 4 more, and they were highly successful on mid-west routes out of Chicago, with their turbines driving the axles through mechanical cardan shaft drives. An option for more was taken up by building an ‘Americanised’ version at Rohr Industries in California – these were 5-car sets, ordered in 1974 and put to work in the mid-west, whilst the UAC ‘Turbotrains’ saw out their days on the NEC between New York and Boston. The new Rohr turbotrains were also intended for the ‘Water Level Route’ north from New York, and modifications included fitting traction motors and third rail collector shoe gear for working in and out of Grand Central Station.
The poor old UAC ‘Turbotrains’ were a failure on the New York to Boston section, and the decision to scrap the extension of electrification north from New Haven left Amtrak without suitable power to run high-speed passenger services. In 1980, a pair of 5-car LRC (Light, Rapid Comfortable) trains appeared on the corridor. These were an existing design from Canadian builders Bombardier/MLW, and already in service with Via Rail, and featured automatic body tilt mechanism that would prove a useful benefit for Amtrak. In fact, the Corporation had been considering this option for Vancouver-Seattle-Portland run, but first set them to work on the northern end of the NEC between New Haven and Boston. They were initially restricted to 90 mph, but on test demonstrated that a curve previously restricted to 50 mph could safely be taken at 70 mph – a major improvement in journey times was clearly possible.
Sadly the LRC sets were returned to Canada at the end of the trial period, as Amtrak once again came up against its perpetual enemy – budget and funding constraints.
So where is the Corporation today? Well, it has genuinely embarked and delivered on a high-speed rail offering for the Northeast Corridor, with over 700 miles of track, serving the most densely populated part of the country, and now has genuine high-speed trains and technology. But it took almost 20 years to deliver the first of the fixed formation train sets.
Once again, Amtrak turned to European expertise to test and determine what was the most suitable offering, and following on from the experience gained with the successful ‘Mighty Mouse’ AEM7 paired with Amfleet cars, returned to Sweden and borrowed an X2000 tilting train set in 1992. With support from ABB, the X2000 not only worked on the NEC, but toured the USA – obviously in part to raise awareness and popularity for trains and railroads. Its regular – if not full time – working was between New Haven, New York and Washington, and during the X2000’s stay, Amtrak agreed with Siemens to test the German ICE train on the same route.
A year later, Amtrak went out to look for bidders to build a new high-speed train for the Corporation, and of course, both Siemens and ABB were in the running, but there was also the Bombardier/Alstom consortium. Bombardier of course had already had some exposure in the USA with the trials of its LRC tilting train. It looked in the 1990s as though Amtrak was heading towards membership of the high-speed club.
The end result was the Acela Express, with an order for 20 of the high-speed fixed formation trains to be designed, tested, built and delivered by the Alstom/Bombardier consortium. The train was operationally intended to be an ‘incremental improvement’ rather than a step change in rail technology as the Japanese “Bullet Trains” or France’s “TGV” had been. It was necessary to further improve the right of way in the northeast, with extensive replacement of existing track with continuous welded rail and concrete ties/sleepers, as well as provide three new maintenance facilities. Some of the right of way work had been carried out under the NEC improvement programme in the 1980s, but even more was needed before “Acela” could be fully operational. This included the rapid completion of electrification work from New Haven to Boston.
In November 2000, the Acela Express made its inaugural run. This was a train like no other seen in the USA before, with 12,000hp available from two power cars, and 6 trailers sandwiched between, to provide a smooth, quiet ride at speeds of up to 240 km/hr. No less than 20 of these trains were built between 1998 and 2001, and their popularity with the travelling public dramatically raised Amtrak’s share of the passenger market. Between New York and Washington DC, passenger share grew from 36% to 53%, and between New York and Boston it was even more marked, going up from 18% to 40%. At the same time, airline passenger share declined from 64% to 47% between the Big Apple and Washington.
It has been a huge success, and in part at least has driven the demand for kickstarting investment in other high-speed rail corridors, from 1992 to 2009. The five corridors defined in 1992 were:
Midwest high-speed rail corridor linking Chicago , IL with Detroit , MI , St. Louis MO and Milwaukee WI
Florida high-speed rail corridor linking Miami with Orlando and Tampa.
California high-speed rail corridor linking San Diego and Los Angeles with the Bay Area and Sacramento via the San Joaquin Valley.
Southeast high-speed rail corridor connecting Charlotte, NC, Richmond, VA, and Washington, DC.
Pacific Northwest high-speed rail corridor linking Eugene and Portland, OR with Seattle, WA and Vancouver, BC, Canada.
Six years later in 1998 the Transportation Equity Act for the 21st Century designated another group of high-speed rail corridors, and extensions to existing plans including:
Gulf Coast high-speed rail corridor.
The Keystone corridor
Empire State corridor
Extension of the Southeast corridor
Extension of the Midwest High-Speed Rail Corridor (now called the Chicago Hub corridor)
Improvements on the Minneapolis/St. Paul- Chicago segment of the Midwest High-Speed Rail Corridor.
Extensions has already been approved to the Southeast corridor in 1995, with further extensions to the Chicago Hu, and the Northern New England route and a new South Central Corridor in 2000, and to date further extensions and expansion of these key corridors are either in plan or approved. On top of this, for the original corridor – the NEC – new generation of Acela high-speed trains has been promised, and already under test, as the attached video shows.
Finally, after almost total dependence on the automobile for long distance as well as commuter travel, the age of the train in the USA is coming into its own. Environmental credentials are high, it is sustainable mass transportation, and popular.
Some 34 years ago, I wrote a feature for the PA Features entitled “High Speed Trains for the 21st Century”, which was essentially a look at some of the then ground breaking innovation, research and ideas in development for rail transport. In 1986, we were in the grip of an explosion of ideas, and that despite the axing by the UK government of the British Rail APT, with its tilting technology. This would later come back to us via Fiat in Italy, and the Virgin operated Pendolino trains – it is perhaps equally ironic that Italy would today, in 2020, also now be operating the UK’s West Coast Pendolino trains.
The railway network of India is vast, and its cities have extensive suburban and metro networks, with Delhi seeing one of the most recent projects to build a 122 km double-track Orbital Rail Corridor. The route will run around the west of Delhi from Palwal in the south to Harsana Kalan in the north, and provide some relief for the severe congestion on the capital’s inner routes. The metro routes in and around Kolkata have also been expanded in recent years, with October seeing the first underground station on the East-West metro line opened for revenue service.
But the first electrification work for India was sanctioned by the government in August 1922, as the railway’s traffic continued to increase, and the escalating costs of coal for steam hauled services. Contracts were let to the Tata Hydro Electric company to provide the power supplies, and English Electric for the supply of substation equipment including rotary converters, circuit breakers and control panels. The 110,000V a.c. supply was delivered to three principal substations at Dharavi, Kalyan & Thane, where it was converted through the English Electric rotary converters to 1500V d.c. as the feed to the overhead catenary.
Each of the substations was equipped with a pair of 1,250 kW, 750V converters, connected in series – the total installed power was 15,000kW. At Kalyan, three of these 2,500kW units were installed, and used English Electric’s own design of automatic switching equipment. The line’s outdoor switchyard was located here too, and included electrically operated oil circuit breakers and the step up transformer for the 110,000V incoming supply, along with other control and auxiliary equipment.
First there was horse, and then steam followed by diesel and electric – and some of these concurrently – and now the future may be a hydrogen fuel cell powered train. In a tenuous link back to the atomic trains proposals of the mid 20th century perhaps, the University of St Andrews is looking to design and test a power plant for rail vehicles, using hydrogen fuel cells, and fit this to an existing rail vehicle platform.
In September, the university published a ‘Prior Information Notice’, to indicate the key boundaries of this home grown project, with a power source that further reduces the rail industry’s dependence on fossil fuels for traction. The idea itself has been around for some time – well since 2018 at least – and no doubt much earlier theoretically.
Back then Birmingham University’s Centre for Railway Research and Education (BCRRE) began development of a project to utilise hydrogen fuel-cell technology on a railway vehicle – their test bed being a former British Rail Class 319 multiple unit. British Rail Engineering Ltd. originally built these electric multiple units, from 1987 onwards, and after privatisation, they were rented by various train operating companies. A number of the class were modified, upgraded in various ways, including a number that were converted to bi-mode units in 2016.
Back in 2018, BCRRE demonstrated a 10 ¼ ins gauge locomotive “Hydrogen Hero” at the Quinton Rail Technology Centre, in Warwickshire, and in partnership with Porterbrook Leasing the Birmingham team went on to design and demonstrate the ‘HydroFLEX’ demonstrator. This was based on Class 319 No. 319001 from Porterbrook, and successfully demonstrated at Quinton in June 2019. Mainline testing followed, and the “HydroFLEX” project was awarded a £400,000 funding grant from a £9.4 million fund for innovative projects this month to develop the final, detailed design for the world’s first bi-mode electric hydrogen train.
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)
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.
Of 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.
The BTC published a series of Temporary Painting Schedules for its inhgerited motive power in late 1948 covering these experimental liveries:
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.
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.
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.

Lettering 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).

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.
