Alstom Hydrogen Aventras And Extension Of The Birmingham Cross-City Line

In Alstom And Eversholt Rail Sign An Agreement For The UK’s First Ever Brand-New Hydrogen Train Fleet, I give my thoughts on Alstom’s new hydrogen train, which I have called the Alstom Hydrogen Aventra.

In that post, decide that the proposed Alstom Hydrogen Aventras are based on the three-car Class 730/0 trains that have been ordered by West Midlands Trains for Birmingham’s electrified Cross-City Line.

I then go on to say.

There are plans to expand the line in the future and I do wonder if the proposed Alstom Hydrogen Aventras could be the ideal trains for extending the network.

Expansion plans are detailed a section called Future, in the Wikipedia entry for the Cross-City Line, where these plans are indicated.

In addition, the Walsall and Wolverhampton Line is being reopened to passenger trains.

These new and possibly other services will need no new tracks, but more electrification and extra new trains.

In 2015, I wrote Electrification May Be In Trouble Elsewhere, But The Brummies Keep Marching On, which looked at electrification progress in the UK and the Birmingham in particular, where the electrification of the Chase Line seemed to be going well. So unlike in some places, where electrification seems to be accident-prone, Birmingham seems to avoid the sort of problems, that happened in the Preston and Blackpool and GOBlin electrifications.

But the Alstom Hydrogen Aventra gives Birmingham and the West Midlands a unique advantage compared to say Leeds or Manchester.

Birmingham can obtain a unified fleet, which to the passengers and the drivers looks the same, but in fact are two separate classes of three-car trains;  the Class 730/0 electric train and the Alstom Hydrogen Aventra.

  • Where electrification exists, the Class 730/0 trains will be used and where there is no electrification, the Alstom Hydrogen Aventra will work the route on hydrogen.
  • All that is needed is to provide good tracks and signalling and the Alstom Hydrogen Aventras will take you where you want to go.
  • Through the centre of Birmingham, these trains will use the existing electrification.
  • It would be a network, that would be simple to expand.

The only other English city to use a similar technique will be Liverpool, where Merseyrail’s new Class 777 trains will use battery power outside of the electrified core.

Conclusion

If Birmingham uses their disused but still existing railway lines and adds new trains as required, they can create a world-class suburban network, with the Cross-City Line at its centre

Alstom Hydrogen Aventras And Great Western Branch Lines Between Paddington And Oxford

In Alstom And Eversholt Rail Sign An Agreement For The UK’s First Ever Brand-New Hydrogen Train Fleet, I give my thoughts on Alstom’s new hydrogen train, which I have called the Alstom Hydrogen Aventra.

One reader suggested these lines in a comment, as they are all run by diesel Class 165 trains.

These are the lines, that could be converted to Hydrogen operation.

Greenford Branch

The branch runs between West Ealing and Greenford via Drayton Green, Castle Bar Park and South Greenford.

  • It has a frequency of two trains per hour (tph).
  • The branch is 2.5 miles long.
  • Services take eleven minutes.
  • It needs a single train to run the service.

Note.

  1. In GWR To Test Battery Train On Branch Line, I wrote about Great Western Railway’s plans to test battery-eclectic trains on this line.
  2. The platform at Greenford station may need lengthening to accommodate the Alstom Hydrogen Aventra.
  3. It is my view that the branch needs four tph.
  4. It might also be possible to run Peak hour services to and from Paddington.

I do think that if the train length issue is solved that a single Alstom Hydrogen Aventra could work this branch.

A two-car Class 230 train would certainly fit.

Windsor Branch

The branch runs between Slough and Windsor & Eton Central.

  • It has a frequency of three tph
  • The branch is 2.8 miles long.
  • Services take six minutes.
  • It needs a single train to run the service.

Note.

  1. The extra capacity of the Alstom Hydrogen Aventra could be welcome.
  2. Prince Charles would like it.

I do think that a single Alstom Hydrogen Aventra could work this branch.

Marlow Branch

The branch runs between Maidenhead and Marlow via Furze Platt, Cookham and Bourne End.

  • It has a frequency of one tph
  • The branch is 7.1 miles long.
  • Services take twenty-three minutes.
  • The service reverses at Bourne End.
  • It needs a single train to run the service.

Note that the three-car Alstom Hydrogen Aventra may be too long to execute the reverse at Bourne End.

I do think that if the Bourne End problem can be solved that a single Alstom Hydrogen Aventra could work this branch.

The two-car Class 165 train, that currently works the branch is 46 metres long, so a two-car battery-electric train may be needed for this branch. A two-car Class 230 train would certainly fit.

Regatta Line

The branch runs between Twyford and Henley-on-Thames via Wargrave and Shiplake.

  • It has a frequency of two tph
  • The branch is 4.6 miles long.
  • Services take twelve minutes.
  • It needs a single train to run the service.

Note.

  1. If this line needed more capacity trains could be doubled up, as there are no length issues.
  2. It might also be possible to run Peak hour services to and from Paddington.

I do think that a single Alstom Hydrogen Aventra could work this branch.

North Downs Line

The line runs between Reading and Gatwick Airport via Wokingham, Crowthorne, Sandhurst, Blackwater, Farnborough North, North Camp, Ash, Guildford, Shalford, Chilworth, Gomshall, Dorking West, Dorking Deepdene, Betchworth, Reigate and Redhill

  • It has a frequency of two tph
  • The route is 53.1 miles long.
  • The route is partially-electrified with 750 VDC third-rail electrification.
  • The route has been planned for 100 mph trains.
  • Services take eighty-two minutes.
  • It needs six trains to run the service.

Note.

  1. The route is proposed to be run by four-car Class 769 bi-mode trains.
  2. Would a three-car train be sufficient for this route?
  3. The Alstom Hydrogen Aventras are only 90 mph trains and would they be fast enough?

I do think that Alstom Hydrogen Aventras could work this route, but given the number of trains and possible capacity and speed issues, a four-car battery-electric train could be better suited to the route.

Reading And Basingstoke Line

This line runs between Reading and Basingstoke via Reading West, Mortimer and Bramley

  • It has a frequency of two tph
  • The route is 15.4 miles long.
  • There is 25 KVAC overhead electrification at Reading.
  • There is 750 VDC third-rail electrification at Basingstoke, but the platform used by the service is unelectrified.
  • The route has been planned for 100 mph trains.
  • Services take twenty-eight minutes.
  • It needs two trains to run the service.

Note.

  1. For a battery-electric train to work this route, it might need a charging system at Basingstoke.
  2. The Alstom Hydrogen Aventras are only 90 mph trains and would they be fast enough?

I do think that a pair of Alstom Hydrogen Aventras could work this service.

Oxford Canal Line

This route runs between Didcot Psrkway and Banbury via Appleford, Culham, Radley, Oxford, Tackley, Heyford and Kings Sutton.

  • It is effectively two routes with a combined frequency of two tph between Didcot Junction and Oxford and half that between Oxford and Banbury.
  • The full route is 33 miles long.
  • There is 25 KVAC overhead electrification at Didcot Parkway.
  • Services take forty-one minutes.
  • It probably needs four trains to run the service.

I do think that a small fleet of Alstom Hydrogen Aventras could work this service.

Some General Thoughts

These are a few general points.

Stabling And Hydrogen Fuelling

Reading Train Care Facility is a large depot to the west of Reading.

  • It is ideally placed for all the lines, that I’ve mentioned.
  • It is connected to all the lines by electrified lines.

I am sure that it would be possible to build a hydrogen fuelling facility at the depot.

Two-Car Battery-Electric Trains

It looks like the Greenford and Marlow Branches might need to be served by two-car battery-electric trains.

Four-Car Trains

Some of the services might be run by four-car trains, as these would be more suitable for the number of passengers.

Total Number Of Trains

My rough estimates of numbers of trains are as follows.

  • Greenford Branch – 1 train
  • Windsor Branch – 1 train
  • Marlow Line – 1 train
  • Regatta Line – 1 train
  • North Downs Line – 6 trains
  • Reading And Basingstoke Line – 2 trains
  • Oxford Canal Line – 4 trains

This would be a total of sixteen trains or ten, if the Class 769 trains were used on the North Downs Line.

Additional Routes

There may be other routes, where the trains could be used, that are handy for Reading Train Care Facility.

Hydrogen or battery power may give advantages in opening new routes.

Would Hydrogen Trains Attract Passengers And Tourists?

I think they could, as if nothing there is a curiosity value.

Conclusion

This collection of routes surround Reading Train Care Facility and would be a nice package to run with hydrogen or battery-electric trains.

Will JCB Dig The Whole World Out Of A Hole?

JCB and the Bamford family in general have form, where hydrogen is concerned.

  • JCB have developed internal combustion engines, that will run on hydrogen.
  • Jo Bamford owns Wrightbus and they are building hydrogen-fuelled buses in Northern Ireland.
  • JCB were an early investor in hydrogen electrolyser company; ITM Power.
  • JCB have signed a large contract for the delivery of hydrogen with Fortescue Future Industries.

I have just watched this amazing video, where Lord Bamford explains his philosophy on hydrogen.

Ballard Buys UK Fuel Cell Specialist Arcola

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

This is the first paragraph.

The Canadian fuel cell manufacturer Ballard Power Systems acquires Arcola Energy, a British specialist for the integration of fuel cell systems in heavy commercial vehicles such as buses, trucks and trains. Both sides had previously worked together for years.

The price is stated as around forty million dollars in cash and shares.

As Arcola started just round the corner from where I live in Dalston, I wish them well!
