Overhauls for LNER’s Remaining Class 91s And Mk 4s

The title of this post, is the same as that of this article on Rail Magazine.

This is the introductory paragraph.

Eversholt Rail, which owns the trains, has confirmed that 12 London North Eastern Railway Class 91s and the remaining Mk 4 coaches will undergo overhauls at Wabtec Rail, Doncaster.

It had been expected, that LNER would purchase more trains, as I wrote about in More New Trains On LNER Wish List.

The article gives more details of the trains to be retained.

  • Twelve Class 91 locomotives, seven rakes of Mark 4 coaches and two spare coaches will be retained.
  • They will be confined to routes between London Kings Cross and Bradford, Leeds, Skipton and York.

How many trains will be needed to cover these routes?

  • Trains take two hours and fifteen minutes between London Kings Cross and Leeds and run at a frequency of two trains per hour (tph)
  • Trains take two hours and twenty-one minutes between London Kings Cross and York and run hourly.
  • I suspect that a round trip to Leeds or York can be five hours.

So a crude analysis says, that will mean fifteen trains will be needed,

But some of these trains will be extended past Leeds.

These are, electrification status and the times and distances between Leeds and the final destinations.

  • Bradford – Electrified – 22 minutes – 13.5 miles
  • Harrogate – Not Electrified – 40 minutes – 18 miles
  • Huddersfield – Not Electrified – 33 minutes – 17 miles
  • Skipton – Electrified  – 45 minutes – 26 miles

It appears that the following is true.

  • Trains serving Harrogate and Huddersfield must be worked by bi-mode Class 800 trains.
  • Trains serving Bradford and Skipton could be worked by InterCity 225 trains or an all-electric nine-car Class 801 train.

Note.

  1. Some times are those taken by LNER services and some are estimates from TransPennine Express.
  2. I have assumed 8-10 minutes for the Split-and-Join at Leeds and included it in the times.
  3. Class 800 trains seem to take around ten minutes to turnround at Harrogate.
  4. Times between London Kings Cross and Doncaster will decrease by a few minutes, with the addition of digital in-cab signalling on the route, which will allow 140 mph running by InterCity 225s, Class 800 trains and Class 801 trains.

I estimate that it will be possible for an InterCity 225, Class 800 train or Class 801 train to do a round trip between London Kings Cross and Bradford, Harrogate, Huddersfield or Skipton in six hours.

The round trip between London Kings Cross and York will be the five hours, I estimated earlier.

Wikipedia also says this.

LNER expects to introduce two-hourly services to Bradford and a daily service to Huddersfield in May 2020 when more Azuma trains have been introduced.

So would the pattern of trains to Leeds/York be as follows?

  • One tph – One pair of five-car Class 800 trains to Leeds, of which some or all split and join at Leeds, with one train going to and from Harrogate and the other going to and from Huddersfield.
  • One tph per two hours (tp2h) – An InterCity 225 or nine-car Class 801 train to Leeds, of which some or all are extended to Bradford.
  • One tp2h – An InterCity 225 or nine-car Class 801 train to Leeds, of which some or all are extended to Skipton.
  • One tph – An InterCity 225 or nine-car Class 801 train to York.

I estimate that it will be possible for an InterCity 225, Class 800 train or Class 801 train to do a round trip between London Kings Cross and Bradford, Harrogate, Huddersfield or Skipton in six hours.

This would need the following trains.

  • Six pairs of five-car Class 800 trains for the Harrogate and Huddersfield services.
  • Six full size all electric trains, which could be an InterCity 225, a nine-car Class 801 train or a pair of five Class 801 trains, for Bradford and Skipton services.
  • Five full size all electric trains, which could be an InterCity 225, a nine-car Class 801 train or a pair of Class 801 trains, for York services.

So why have LNER changed their mind and are retaining the InterCity 225?

Are InterCity 225 Trains Already Certified For 140 mph Running?

I wouldn’t be surprised, if a large part of the certification work for this had been done for 140 mph running and for it to be allowed, it needs digital in-cab signalling to be installed on the East Coast Main Line.

The Wikipedia entry for the InterCity 225 says this about the train’s performance.

The InterCity 225 has a top service speed of 140 mph (225 km/h); during a test run in 1989 on Stoke Bank between Peterborough and Grantham an InterCity 225 reached 162 mph (260.7 km/h). However, except on High Speed 1, which is equipped with cab signalling, British signalling does not allow trains to exceed 125 mph (201 km/h) in regular service, due to the impracticality of correctly observing lineside signals at high speed.

The Wikipedia entry for the East Coast Main Line says this about the future signalling.

A new Rail operating centre (ROC), with training facilities, opened in early 2014 at the “Engineer’s Triangle” in York. The ROC will enable signalling and day-to-day operations of the route to be undertaken in a single location. Signalling control/traffic management using ERTMS is scheduled to be introduced from 2020 on the ECML between London King’s Cross and Doncaster – managed from the York ROC.

A small fleet of InterCity 225 trains could be the ideal test fleet to find all the glitches in the new signalling.

Are InterCity 225 trains Already Certified To Run To Bradford and Skipton?

If they are, then that is another problem already solved.

A Fleet Of Seven Trains Would Cover Bradford And Skipton Services

Six trains are needed to run a one tp2h service to both Bradford and Skipton, so they could fully cover one tp2h to Bradford and occasional trains to Skipton with a spare train and one in maintenance.

Using InterCity 225s To Bradford and Skipton Would Not Require A Split-And-Join At Leeds

The number of trains that would Split-and-Join at Leeds would be only two tph instead  of four tph, which would be simpler with less to go wrong.

Not Enough Five-Car Bi-Mode Class 800 Trains

LNER’s full fleet of Azumas will be as follows.

  • 13 – Nine-car bi-mode Class 800 trains.
  • 10 – Five-car bi-mode Class 800 trains.
  • 30 – Nine-car electric Class 801 trains.
  • 12 – Five-car electric Class 801 trains.

This would appear to be a major problem, if Harrogate and Huddersfield were to be served hourly by Class 800 trains, existing services are to be maintained or even increased to Hull and Lincoln and extra services are to be added to Middlesbrough and perhaps Nottingham and other destinations.

The InterCity 225s only help indirectly, if they provided the London Kings Cross and Bradford and Skipton services.

Conversion Of Class 800 and Class 801 Trains To Regional Battery Trains

Hitachi have launched the Regional Battery Train, which is described in this Hitachi infographic.

For LNER, they will be useful for any Journey under about 90 kilometres or 56 miles.

The trains should be able to serve these routes.

  • Leeds and Harrogate and back – 36 miles
  • Leeds and Huddersfield and back – 34 miles
  • Newark and Lincoln and back – 33 miles
  • Northallerton and Middlesbrough and back – 42 miles

Whilst Class 800 trains and Class 801 trains are converted, the InterCity 225 trains would act as valuable cover on services like London to Leeds and York.

Conclusion

I think it is a good plan.

£35m Station Transformation Launched By Tees Valley Mayor

The title of this post, is the same as that of this article on Rail Technology Magazine.

This is the introductory paragraph.

Tees Valley Mayor Ben Houchen has announced (June 9th) a £35m transformation of Middlesbrough Station to transport more train services to the town, including the first direct rail link to London in decades.

The Rail Technology Magazine article indicates that Platform 2 at Middlesbrough station will be extended to handle Azuma trains. As the current platform looks to be around 150 metres long and this would be long enough for a five-car train, does this mean that in the future nine-car and ten-car Azumas will be able to run services to Middlesbrough?

Currently, LNER run one train per two hours (tp2h) between London and York. Could some or all of these trains be extended to Middlesbrough?

  • TransPennines’ trains between York and Middlesbrough take fifty-eight minutes, but they are timed for slower Class 185 trains.
  • I would expect faster Class 800 trains could go between York and Middlesbrough and back to York in under a convenient two hours.
  • In addition, the lengthened Platform 2 at Middlesbrough would allow longer trains on the service between London and York to turn back at Middlesbrough.
  • As the York service, which has a frequency of 1tp2h shares a path with the Lincoln service of a similar frequency, there must be the possibility to run a 1tp2h between Kings Cross and Middlesbrough.
  • The same path is also used to run one train per day (tpd) to and from Hull.
  • It should also be noted that all Class 800 trains have the ability to split and join together in under two minutes.

There would appear to be a large amount of scope to develop a comprehensive timetable between Kings Cross and Hull, Lincoln and Middlesbrough.

  • If the first train left at 07:06 and the last at 22:06, there could be sixteen trains per day on the Kings Cross and Lincoln, Hull, York and Middlesbrough route.
  • Each train could be two five-car trains that split and joined en route, which means there would be a total of 32 tpd.
  • If five tpd went to both Lincoln and Middlesbrough and perhaps three tpd to Hull, that would leave nineteen tpd trains for other destinations.
  • As many trains as possible would need to call at York.

I can certainly see extra destinations built into a intricate pattern in Lincolnshire, Yorkshire and County Durham.

  • Nottingham could be served from Newark.
  • Grimsby and Cleethorpes could be served by extending services from Lincoln.
  • Sheffield, Hull, Scunthorpe, Grimsby and Cleethorpes could be serves from Doncaster.
  • Scarborough could be served from York.
  • Washington and Newcastle could be served on an alternative route using a reopened Leamside Line.
  • Sunderland could be served by extending services from Middlesbrough along the Durham Coast Line.
  • Saltburn and Redcar could be served by extending services from Middlesbrough.

Splitting and joining could occur at the following stations.

  • Newark for Nottingham and Lincoln, Grimsby and Cleethorpes
  • Doncaster for Sheffield, Hull and Scunthorpe, Grimsby and Cleethorpes.
  • York for Scarborough and Middlesbrough.
  • Middlesbrough for Sunderland and Redcar and Saltburn

Middlesbrough station would need to be able to take two five-car trains for splitting and joining, so the platform extension is required.

Kings Cross and Middlesbrough Could Be A Zero-Carbon Route

In Could Some of Hitachi’s Existing Trains In The UK Be Converted To Battery-Electric Trains?, I indicated that as Middlesbrough station is only 21 miles and 29 minutes from Northallerton and the East Coast Main Line, that a five-car Azuma train converted to battery-electric operation should be able to run between Middlesbrough and Kings Cross, totally on electric power, which would be zero-carbon, if the electricity were to be renewable.

Fuelling The Change On Teesside Rails

The title of this post, is the same as that of an article in Edition 895 of RAIL Magazine.

The article is based on an interview with Ben Houchen, who is the Tees Valley Mayor.

Various topics are covered.

Hydrogen-Powered Local Trains

According to the article, the Tees Valley produces fifty percent of UK hydrogen and the area is already secured investment for fuelling road vehicles with hydrogen.

So the Tees Valley Combined Authority (TVCA) is planning to convert some routes to hydrogen.

The Trains

Ten hydrogen-powered trains will be purchased or more likely leased, as the trains will probably be converted from redundant electrical multiple units, owned by leasing companies like Eversholt Rail and Porterbrook.

The RAIL article says that the first train could be under test in 2021 and service could be started in 2022.

That would certainly fit the development timetables for the trains.

Lackenby Depot

A depot Will Be Created At Lackenby.

  • The site is between Middlesbrough and Redcar.
  • It already has rail and hydrogen connections.

This Google Map shows the area.

Note the disused Redcar British Steel station, which is still shown on the map.

I remember the area from the around 1970, when I used to catch the train at the now-closed Grangetown station, after visits to ICI’s Wilton site. It was all fire, smoke, smells and pollution.

Darlington Station

Darlington station will also be remodelled to allow more services to operate without conflicting with the East Coast Main Line.

Wikipedia says this under Future for Darlington station.

As part of the Tees Valley Metro, two new platforms were to be built on the eastern edge of the main station. There were to be a total of four trains per hour, to Middlesbrough and Saltburn via the Tees Valley Line, and trains would not have to cross the East Coast Main Line when the new platforms would have been built. The Tees Valley Metro project was, however, cancelled.

It does sound from reading the RAIL article, that this plan is being reinstated.

Would services between Bishop Auckland and Saltburn, use these new platforms?

Saltburn And Bishops Auckland Via Middlesbrough and Darlington

Currently, the service is two trains per hour (tph) between Saltburn and Darlington, with one tph extending to Bishop Auckland.

  • I estimate that the current service needs five trains.
  • If a two tph service were to be run on the whole route, an extra train would be needed.
  • I suspect, the limitations at Darlington station, stop more trains being run all the way to Bishops Auckland.

I could also see extra stations being added to this route.

The Mayor is talking of running a service as frequent as six or eight tph.

These numbers of trains, will be needed for services of different frequencies between Saltburn and Darlington.

  • 2 tph – 6 trains
  • 4 tph – 12 trains
  • 6 tph – 18 trains
  • 8 tph – 24 trains

As the London Overground, Merseyrail and Birmingham’s Cross-City Line, find four tph a more than adequate service, I suspect that should be provided.

After updating, Darlington station, should be able to handle the following.

  • Up to six tph terminating in one of the new Eastern platforms, without having to cross the East Coast Main Line.
  • Two tph between Saltburn and Bishops Auckland could use the other platform in both directions.

I would suspect that the design would see the two platforms sharing an island platform.

Alternatively, trains could continue as now.

  • Terminating trains could continue to use Platform 2!
  • Two tph between Saltburn and Bishops Auckland stopping in Platforms 1 (Eastbound) and 4 (Westbound)

This would avoid any infrastructure changes at Darlington station, but terminating trains at Darlington would still have to cross the Southbound East Coast Main Line.

If the frequencies were as follows.

  • 4 tph – Saltburn and Darlington
  • 2 tph – Saltburn and Bishop Auckland

This would require fourteen trains and give a six tph service between Saltburn and Darlington.

Ten trains would allow a two tph service on both routes.

There would be other services using parts of the same route, which would increase the frequency.

Hartlepool And The Esk Valley Line Via Middlesbrough

This is the other route through the area and was part of the cancelled Tees Valley Metro.

  • Service is basically one tph, with six trains per day (tpd) extending to Whitby.
  • A second platform is needed at Hartlepool station.
  • There is a proposal to add a Park-and-Ride station between Nunthorpe and Great Ayton stations.
  • One proposal from Modern Railways commentator; Alan Williams, was to simplify the track at Battersby station to avoid the reverse.
  • Currently, trains between Whitby and Middlesbrough are timetabled for around 80-100 minutes.
  • Hartlepool and Middlesbrough takes around twenty minutes.

Substantial track improvements are probably needed to increase the number of trains and reduce the journey times between Middlesbrough and Whitby.

But I believe that an hourly service between Hartlepool and Whitby, that would take under two hours or four hours for a round trip, could be possible.

This would mean that the hourly Hartlepool and Whitby service would need four trains.

Providing the track between Nunthorpe and |Whitby could be improved to handle the traffic, this would appear to be a very feasible proposition.

Nunthorpe And Hexham Via Newcastle

There is also an hourly service between Nunthorpe and Hexham, via Middlesbrough, Stockton, Hartlepool, Sunderland and Newcastle, there would be two tph.

  • It takes around two hours and twenty minutes.
  • I estimate that five trains would be needed for the service.
  • I travelled once between Newcastle and James Cook Hospital in the Peak and the service was busy.
  • A new station is being built at Horden, which is eight minutes North of Hartlepool.
  • The service could easily access the proposed fuelling station at Lackenby.
  • It would reduce carbon emissions in Newcastle and Sunderland stations..

Surely, if hydrogen power is good enough for the other routes, then it is good enough for this route.

Hartlepool Station

Hartlepool Station could become a problem, as although it is on a double track railway, it only has one through platform, as these pictures from 2011 show.

Consider.

  • There is no footbridge, although Grand Central could pay for one
  • There is a rarely-used bay platform to turn trains from Middlesbrough, Nunthorpe and Whitby.

This Google Map shows the cramped site.

The final solution could mean a new station.

Nunthorpe Park-And-Ride

This Google Map shows Nunthorpe with thje bEsk Valley Line running through it.

Note.

  1. Gypsy Lane and Nunthorpe stations.
  2. The dual-carriageway A171 Guisborough by-pass running East-West, that connects in the East to Whitby and Scarborough.
  3. The A1043 Nunthorpe by-pass that connects to roads to the South.

Would where the A1043 crosses the Esk Valley Line be the place for the Park-and-Ride station?

The new station could have a passing loop, that could also be used to turn back trains.

Battersby Station

Alan Williams, who is Chairman of the Esk Valley Railway Development Company, is quoted in the RAIL article as saying.

If you’re going to spend that sort of money we’d much rather you spent it on building a curve at Battersby to cut out the reversal there.

Williams gives further reasons.

  • Battersby is the least used station on the line.
  • It’s in the middle of nowhere.
  • The curve would save five minutes on the overall journey.

This Google Map shows Battersby station and the current track layout.

Note.

  1. The line to Middlesbrough goes through the North-West corner of the map.
  2. The line to Whitby goes through the North-East corner of the map.

There would appear to be plenty of space for a curve that would cut out the station.

LNER To Teesside

LNER, the Government and the TVCA are aiming to meet a target date of the Second Quarter of 2021 for a direct London and Middlesbrough service.

Middlesbrough Station

Middlesbrough Station will need to be updated and according to the RAIL article, the following work will be done.

  • A new Northern entrance with a glass frontage.
  • A third platform.
  • Lengthening of existing platforms to take LNER’s Class 800 trains.

This Google Map shows the current layout of the station.

From this map it doesn’t look to be the most difficult of stations, on which to fit in the extra platform and the extensions.

It should also be noted that the station is Grade II Listed, was in good condition on my last visit and has a step-free subway between the two sides of the station.

Journey Times

I estimate that a Kings Cross and Middlesbrough time via Northallerton would take aroud two hours and fifty minutes.

This compares with other journey times in the area to London.

  • LNER – Kings Cross and Darlington – two hours and twenty-two minutes
  • Grand Central – Kings Cross and Eaglescliffe – two hours and thirty-seven minutes.

I also estimate that timings to Redcar and Saltburn would be another 14 and 28 minutes respectively.

Frequencies

Currently, LNER run between three and four tph between Kings Cross and Darlington, with the competing Grand Central service between Kings Cross and Eaglescliffe having a frequency of five trains per day (tpd).

LNER have also started serving secondary destinations in the last month or so.

  • Harrogate, which has a population of 75.000, is served with a frequency of six tpd.
  • Lincoln, which has a population of 130,000 is now served with a frequency of six tpd.

Note that the RAIL article, states that the Tees Valley has a population of 750,000.

I feel that Middlesbrough will be served by a frequency of at least five tpd and probably six to match LNER’s new Harrogate and Lincoln services.

Will LNER’s Kings Cross and York Service Be Extended To Middlesbrough?

Cirrently , trains that leave Kings Cross at six minutes past the hour end up in Lincoln or York

  • 0806 – Lincoln
  • 0906 – York
  • 1006 – Lincoln
  • 1106 – York
  • 1206 -Lincoln
  • 1306 – York
  • 1406 – Lincoln
  • 1506 – York
  • 1606 – Lincoln
  • 1906 -Lincoln

It looks to me that a pattern is being developed.

  • Could it be that the York services will be extended to Middlesbrough in 2021?
  • Could six Middlesbrough trains leave Kings Cross at 0706, 0906, 1106, 1306, 1506 and 1706 or 1806?
  • York would still have the same number of trains as it does now!

LNER certainly seem to be putting together a comprehensive timetable.

Could Middlesbrough Trains Split At Doncaster Or York?

I was in Kings Cross station, this afternoon and saw the 1506 service to York, go on its way.

The train was formed of two five-car trains, running as a ten-car train.

If LNER employ spitting and joining,, as some of their staff believe, there are surely, places, where this can be done to serve more destinations, without requiring more paths on the East Coast Main Line.

  • Splitting at Doncaster could serve Hull, Middlesborough and York.
  • Splitting at York could serve Scarborough, Middlesborough and Sunderland.

Scarborough might be a viable destination, as the town has a population of over 100,000.

Onward To Redcar And Saltburn

One of the changes in the December 2019 timetable change, was the extension of TransPennine Express’s Manchester Airport and Middlesbrough service to Redcar Central station.

The RAIL article quotes the Mayor as being pleased with this, although he would have preferred the service to have gone as far as Saltburn, which is a regional growth point for housing and employment.

But the extra six miles would have meant the purchase of another train.

Redcar Central Station

This Google Map shows Redcar Central station and its position in the town.

It is close to the sea front and the High Street and there appears to be space for the stabling of long-distance trains to Manchester Airport and perhaps, London.

TransPennine seem to be using their rakes of Mark 5A coaches on Redcar services, rather than their Class 802 trains, which are similar to LNER’s Azumas.

Surely, there will be operational advantages, if both train operating companies ran similar trains to Teesside.

Saltburn Station

Saltburn station is the end of the line.

This Google Map shows its position in the town.

Unlike Redcar Central station, there appears to be very little space along the railway and turning back trains might be difficult.

There may be good economic reasons to use Saltburn as a terminal, but operationally, it could be difficult.

Will Redcar And Saltburn See Services To and From London?

Given that both towns will likely see much improved services to Middlesbrough, with at least a service of four tph, I think it will be unlikely.

But we might see the following.

  • LNER using Redcar as a terminus, as TransPennine Express do, as it might ease operations.
  • An early morning train to London and an evening train back from the capital, which is stabled overnight at Redcar.
  • TransPennine Express using Class 802 trains on their Redcar service for operational efficiency, as these trains are similar to LNER’s Azumas.

It would all depend on the passenger numbers.

A High-Frequency Service Between York And Teesside

After all the changes the service between York and Teesside will be as follows.

  • LNER will be offering a train virtually every two hours between York and Middlesbrough.
  • Grand Central will be offering a train virtually every two hours between York and Eaglescliffe, which is six miles from Middlesbrough.
  • TransPennine Express will have an hourly service between York and Redcar via Middlesbrough.
  • There will be between three and four tph between York and Darlington.

All services would connect to the hydrogen-powdered local services to take you all over Teesside.

Could this open up tourism without cars in the area?

Expansion Of The Hydrogen-Powered Train Network

Could some form of Hydrogen Hub be developed at Lackenby.

Alstom are talking of the hydrogen-powered Breeze trains having a range of over six hundred miles and possibly an operating speed of 100 mph, when using overhead electrification, where it is available.

In Breeze Hydrogen Multiple-Unit Order Expected Soon, I put together information from various articles and said this.

I am fairly certain, that Alstom can create a five-car Class 321 Breeze with the following characteristics.

  • A capacity of about three hundred seats.
  • A smaller three-car train would have 140 seats.
  • A near-100 mph top speed on hydrogen-power.
  • A 100 mph top speed on electrification.
  • A 1000 km range on hydrogen.
  • Regenerative braking to an on-board battery.
  • The ability to use 25 KVAC overhead and/or 750 VDC third rail electrification.

The trains could have the ability to run as pairs to increase capacity.

The distance without electrification to a selection of main stations in the North East from Lackenby is as follows.

  • Newcastle via Middlesbrough and Darlington – 21 miles
  • Newcastle via Middlesbrough and Durham Coast Line – 53 miles.
  • York via Northallerton – 27 miles
  • Doncaster via Northallerton and York – 27 miles
  • Leeds via Northallerton and York – 52 miles
  • Sheffield via Northallerton, York and Doncaster – 45 miles

I am assuming that the trains can use the electrification on the East Coast Main Line.

From these figures it would appear that hydrogen-powered trains stabled and refuelled at Lackenby could travel to Doncaster, Newcastle, Leeds, Sheffield or York before putting in a days work and still have enough hydrogen in the tank to return to Lackenby.

Several things would help.

  • As hydrogen-powered trains have a battery, with a battery range of thirty miles all these main stations could be reached on battery power, charging on the East Coast Main Line and at Lackenby.
  • Electrification between Darlington and Lackenby.
  • Electrification between Northallerton and Eaglescliffe.

I am fairly certain that a large proportion of the intensive network of diesel services in the North East of |England from Doncaster and Sheffield in the South to Newcastle in the North, can be replaced with hydrogen-powered trains.

  • Trains could go as far West as Blackpool North, Carlisle, Manchester Victoria, Preston and Southport.
  • Refueling could be all at Lackenby, although other refuelling points could increase the coverage and efficieny of the trains.
  • Green hydrogen could be produced by electrolysis from the massive offshore wind farms off the Lincolnshire Coast.
  • Hydrogen-powered trains would be ideal for re-opened routes like the proposed services from Newcastle to Blyth and Ashington.

The hydrogen-powered trains on Teesside could be the start of a large zero-carbon railway network.

The Alstom Breeze And The HydroFlex Would Only Be The Start

As I said earlier, the initial trains would be conversions of redundant British Rail-era electrical multiple units.

Thirty-year-old British Rail designs like the Class 319 and Class 321 trains based on the legendary Mark 3 carriages with its structural integrity and superb ride, may have been state-of-the-art in their day, but engineers can do better now.

  • Traction and regenerative braking systems are much more energy efficient.
  • Train aerodynamics and rolling resistance have improved, which means less energy is needed to maintain a speed.
  • Interior design and walk-through trains have increased capacity.
  • Crashworthiness has been improved.

Current Bombardier Aventras, Stadler Flirts or Siemens Desiros and CAF Civities are far removed from 1980s designs.

I can see a design for a hydrogen-powered train based on a modern design, tailored to the needs of operators being developed.

A place to start could be an electric CAF Class 331 train. or any one of a number of Aventras.

  • From the visualisation that Alstom have released of their Breeze conversion of a Class 321 train, I feel that to store enough hydrogen, a large tank will be needed and perhaps the easiest thing to do at the present time would be to add an extra car containing the hydrogen tank, the fuel cells and the batteries.
  • Alstom have stated they’re putting the fuel cells on the roof and the batteries underneath the train.

Although, it is not a hydrogen train, Stadler have developed the Class 755 train, with a power car in the middle of the train.

Stadler’s approach of a power car, must be working as they have received an order for a hydrogen-powered version of their popular Flirts, which I wrote about in MSU Research Leads To North America’s First Commercial Hydrogen-Powered Train.

I think we can be certain, that because of the UK loading gauge, that a hydrogen-powered train will be longer by about a car, than the equivalent electric train.

I can see a certain amount of platform lengthening being required. But this is probably easier and less costly than electrification to achieve zero-carbon on a route.

Batteries can be distributed under all cars of the train, anywhere there is space., But I would suspect that fuel cells must be in the same car as the hydrogen tank, as I doubt having hydrogen pipes between cars would be a good idea.

Alstom have resorted to putting hydrogen tanks and fuel cells in both driving cars and they must have sound reasons for this.

Perhaps, it is the only way, they can get the required power and range.

As I understand it, the Alstom Breeze draws power from three sources.

  • The electrification if the route is electrified.
  • The electricity generated by regenerative braking.
  • The hydrogen system produces electricity on demand, at the required level.

Energy is stored in the batteries, which power the train’s traction motors and internal systems.

The electrical components needed for the train are getting smaller and lighter and I feel that it should be possible to put all the power generation and collection into a power car, that is somewhere near the middle of the train. Stadler’s power car is short at under seven metres, but there is probably no reason, why it couldn’t be the twenty metres, that are typical of UK trains.

Suppose you took a four-car version of CAF’s Class 331 train, which has two driver cars either side of a pantograph car and a trailer car.

This has 284 seats and by comparison with the three-car version the trailer car has eighty. As the pantograph car is also a trailer, I’ll assume that has eighty seats too! Until I know better!

Replacing the pantograph car with a hydrogen car, which would be unlikely to have seats, would cut the seats to 204 seats, but a second trailer would bring it back up to 284 seats.

I actually, think the concept of a hydrogen car in the middle of a four-car electric train could work.

  • The five-car hydrogen train would have the same capacity as the four-car electric version.
  • The train would need an updated software system and some rewiring. Bombardier achieved this quickly and easily with the train for the Class 379 BEMU trial.
  • There are several types of four-car electrical multiple units, that could possibly be converted to five-car hydrogen-powered multiple units.
  • Some five-car electrical multiple units might also be possible to be converted.
