The Anonymous Widower

The Development of Liverpool Street And Paddington Stations

This article in The Telegraph is entitled Row Over ‘Grotesque’ £1.5bn Liverpool Street Revamp.

There is no doubt that Liverpool Street and Paddington stations will need a higher number of trains per hour and this will probably mean more platforms. But there is no space in either station.

Suppose a long-distance version of the current nine-car Alstom/Bombardier trains were to be built with toilets, a 110 mph top speed, but dimensionally identical to the existing Class 345 trains.

The Central Tunnel of the Elizabeth Line could probably handle more trains, than it currently does, given that Dear Old Vicky handles 36 trains per hour.

So services like Southend and Oxford or Beaulieu and Newbury could be run through the Central Tunnel, replacing the current Greater Anglia and GWR services.

This would relieve platform space in the current terminals and the high-speed Elizabeth Line trains, would just be more trains going through the Central Tunnel at 80 mph.

The important Oxford and Cambridge route would be one change at either Farringdon or Liverpool Street, Or with some track modifications, it might be possible to run direct via the Central Tunnel, Stratford and the West Anglia Main Line.

Sorting out the trains, would ease the development of Liverpool Street and Paddington stations.

Could Chiltern Go Battery-Electric?

In the October 2022 Edition of Modern Railways, there is an article, which is entitled Chiltern Considers Turbo Future, with a sub-title of Battery Replacement Could Be On The Cards.

These are the first two paragraphs.

In early September Chiltern Railways was preparing to launch a market sounding exercise to consider options for the future of the Class 165 Turbo DMU fleet.

The operator has 28×2-car and 11×3-car ‘165s’. which operate alongside its more modern Class 168 DMUs and its loco-hauled sets. The market sounding exercise will consider two options for the future of the fleet – some sort of hybrid conversion, or outright replacement.

The Class 165 Trains

The Class 165 trains were built in 1990-1991.

  • Maximum Speed – 75 mph
  • Prime Movers – One per car, Perkins 2006-TWH
  • 2-car Trains – 28
  • 3-car Trains – 11

One is being converted to a diesel/battery hybrid.

The Class 168 Trains

The Class 168 trains were built in 1998-2004.

  • Maximum Speed – 100 mph
  • Prime Movers – One per car, MTU 6R 183TD13H
  • 2-car Trains – 9
  • 3-car Trains – 8
  • 4-car Trains – 11

One has been converted to a diesel/battery hybrid.

Conversion To Hybrid Operation

If this proves to be feasible, it will surely be the more affordable of the two options.

But it does leave Chiltern with a mixed fleet with two types of train with different maximum speeds and these lengths.

  • 2-car Trains – 37
  • 3-car Trains – 19
  • 4-car Trains – 11

Would a fleet of similar trains, with perhaps a maximum speed of 100 mph, be better operationally?

Battery-Electric Operation

The Modern Railways article introduces the concept of battery-electric operation with this paragraph.

If a replacement fleet is considered the best option for the Turbo units, the replacements could take the form of a straight battery EMU, taking advantage of recent advances in ‘fast charge’ technology.

The article also says this about battery technology and electrification.

There is optimism that advances in battery technology will provide a smooth pathway to decarbonise Chiltern’s operations – the company serves the only non-electrified London terminus.

In the longer-term, it is hoped electrification from Birmingham to Banbury as part of a strategy to decarbonise CrossCountry and freight services would enable Chiltern to run a battery EMU on London to Birmingham duties, running under battery power as far north as Banbury and switching to overhead wires from there, both powering the unit and enabling the batteries to be recharged.

The Modern Railways article looked at each route and I will do this in more detail.

London Marylebone And Aylesbury via High Wycombe

London Marylebone and Oxford would be under battery operation for 40 miles.

Trains would be charged at London Marylebone and Aylesbury stations.

London Marylebone And Aylesbury Vale Parkway

London Marylebone and Oxford would be under battery operation for 41 miles.

Trains would be charged at London Marylebone and Aylesbury Vale Parkway stations.

It might be better to electrify between Aylesbury and Aylesbury Vale Parkway stations.

London Marylebone And Banbury

London Marylebone and Oxford would be under battery operation for 69 miles.

Trains would be charged at London Marylebone and Banbury stations.

Leamington Spa And Birmingham Moor Street

Assuming the Birmingham and Banbury section of the route is electrified, this route will be electrified.

London Marylebone And Birmingham Moor Street Or Birmingham Snow Hill

Assuming the Birmingham and Banbury section of the route is electrified, this route can be considered to be in two sections.

  • London Marylebone and Banbury – Battery operation – 69 miles
  • Banbury and Birmingham – Electric operation – 42 miles

Trains would be charged at London Marylebone station and on the electrified section.

London Marylebone And Gerrards Cross

London Marylebone and Oxford would be under battery operation for 19 miles or 38 miles both ways.

Trains would be charged at London Marylebone station.

London Marylebone And High Wycombe

London Marylebone and Oxford would be under battery operation for 28 miles or 56 miles both ways.

Trains would be charged at London Marylebone station.

London Marylebone And Oxford

London Marylebone and Oxford would be under battery operation for 66.8 miles.

Trains would be charged at London Marylebone and Oxford stations.

London Marylebone And Stratford-upon-Avon

Assuming the Birmingham and Banbury section of the route is electrified, this route can be considered to be in two sections.

  • London Marylebone and Banbury – Battery operation – 69 miles
  • Banbury and Hatton Junction – Electric operation – 26 miles
  • Hatton Junction and Stratford-upon-Avon – Battery operation – 9 miles

Trains would be charged at London Marylebone station and on the electrified section.

Chiltern’s Mainline Service

Chiltern’s Mainline service between London and Birmingham is run by either a Class 68 locomotive pulling a rake of six Mark 3 coaches and a driving van trailer or two or three Class 168 trains.

As the locomotive-hauled train is about eight coaches, it could surely be replaced by two four-car multiple units working together.

I believe that if Chiltern obtained a fleet of four-car battery electric trains, this would be the most efficient fleets for all their routes.

Charging At London Marylebone Station

I took these pictures at Marylebone station today.

Note.

  1. It is a surprisingly spacious station and I feel that Furrer+Frey or some other specialist company could add some form of charging to the platforms.
  2. Charging would probably performed using the train’s pantograph.

It appears that the turnround time in Marylebone is typically twelve minutes or more, which should be adequate to fully charge a train.

 

Conclusion

Both solutions will work for Chiltern.

But I prefer the new battery-electric train, which has some crucial advantages.

  • Battery-electric trains will be quieter than hybrid trains.
  • Marylebone station has a noise problem and battery-electric trains are very quiet.
  • Chiltern have ambitions to built new platforms at Old Oak Common and to serve Paddington. This could be easier with a battery electric train.

Rhe only disadvantage is that Banbury and Birmingham would need to be electrified.

Extending The Elizabeth Line – Connecting Great Western Main Line Services To The Central Tunnel

If say it was ever needed to run a train between Oxford or Swindon stations and the Central Tunnel of the Elizabeth Line, three things must be possible.

Trains Would Have To Be Compatible With The Central Tunnel Of The Elizabeth Line

As any train would have to be compatible with the platform-edge doors in the central tunnel of the Elizabeth Line, the trains would have to be dimensionally identical to the current Class 345 trains.

  • Nine cars
  • Possibility of lengthening to ten cars.
  • 204.73 metres long.
  • 6 sets of doors per carriage
  • Ability to run under full digital signalling.

I covered this in detail in Extending The Elizabeth Line – High Speed Trains On The Elizabeth Line.

Trains Would Need A 125 mph Capability To Travel On The Fast Lines Of The Great Western Main Line

They would be designed for a higher speed of at least 110 or 125 mph, to enable running on the fast lines.

The faster running would ease scheduling of the trains.

Effectively, the train would be a Class 345 train with more features and considerably more grunt.

Trains Must Be Able To Connect Between The Fast Lines And The Central Tunnel Of The Elizabeth Line At Royal Oak

This map from cartometro.com shows the track layout at Royal Oak.

Note.

  1. The Elizabeth Line is shown in purple.
  2. Great Western Railway (GWR)  tracks are shown in black.
  3. Where the Elizabeth Line shares the tracks with GWR services the tracks are shown in black and purple.

This map shows an enlargement of Kensal Green East Junction in the North-West corner of the previous map.

Note.

  1. The top pair of lines lead to the Elizabeth Line Depot at Old Oak Common.
  2. the pair of lines that are shown in black and purple handle Elizabeth Line and GWR local services.
  3. The pair of black lines are the Great Western Main Line.
  4. North Pole Depot is used by GWR for their Hitachi trains.

 

This map shows an enlargement between Ladbroke Grove Junction and Royal Oak.

Note.

  1. In the South-East corner of the map is Subway junction, which appears to have two crossovers for maximum flexibility.
  2. To the East of Subway junction the curved line indicates the Royal Oak Portal of the Elizabeth Line Central Tunnel.
  3. To the West of Subway junction, there is Paddington New Yard, where there is five tracks labelled CRL Eastbound, Turnback C, Turnback B, Turnback A and CRL Westbound from North to South.
  4. Turnback C, Turnback B and Turnback A are the three turnback sidings, where trains are turned back East through the Elizabeth Line Central Tunnel.
  5. CRL Eastbound and CRL Westbound can be followed across the map to the black and purple lines of the Elizabeth Line to the West of Ladbroke Grove junction.
  6. At present the Western section of the Elizabeth Line terminates in Paddington station. Crossovers at Portobello junction appear to connect the Western section of the Elizabeth Line into Paddington station.
  7. More crossovers also appear to connect the Great Western Main Line to the CRL Eastbound and CRL Westbound through Paddington New Yard.

I am fairly sure that the track layout at Royal Oak allows trains to go both ways between Great Western Main Line and the Elizabeth Line Central Tunnel.

Extending The Elizabeth Line – High Speed Trains On The Elizabeth Line

This may seem rather fanciful, but could it be the way to maximise the use of the Elizabeth Line?

  • I feel that the Elizabeth Line will eventually serve other destinations like Basingstoke, Beaulieu, Oxford, Southend and Swindon.
  • The capacity of the Elizabeth Line will grow to over thirty trains per hour (tph) under control of digital signalling.

These are a few thoughts.

The Design Of The Trains

As any train would have to be compatible with the platform-edge doors in the central tunnel of the Elizabeth Line, the trains would have to be dimensionally identical to the current Class 345 trains.

  • Nine cars
  • Possibility of lengthening to ten cars.
  • 204.73 metres long.
  • 6 sets of doors per carriage
  • Ability to run under full digital signalling.

They would be designed for a higher speed of at least 110 or 125 mph, to enable running on the fast lines of these routes.

  • East Coast Main Line
  • Great Western Main Line
  • Midland Main Line
  • West Coast Main Line

They would also be able to run at 100 mph on the Chiltern Main Line, the Great Eastern Main Line and the North Kent Line.

The faster running would ease scheduling of the trains.

Extra facilities could include.

  • Toilets
  • Tables
  • A third-rail capability for running in Kent.

Effectively, it would be a Class 345 train with more features and considerably more grunt.

Note that in A High Speed Train With An IPEMU-Capability, I started the post with the following.

Bombardier were reported by Ian Walmsley in the April 2016 Edition of Modern Railways, to be developing Aventra, with a 125 mph capability.

Bombardier have also told me, that all Aventras will be wired so they could be fitted with on-board energy storage.

Could it be that the design of a Class 345 train could be modified to run at higher speeds? I wouldn’t be surprised.

Oxford To Southend Victoria

This could be a typical route.

  • Between Oxford and Paddington, it would follow a route similar to the GWR’s Oxford service with stops at just Reading and Slough.
  • At Paddington the train would take the Central Tunnel of the Elizabeth Line and travel under London, at the same speed as the other trains.
  • It would emerge at Stratford and move to the Great Eastern Main Line.
  • It would probably stop at Stratford, Romford, Shenfield and all stations to Southend Victoria.

Note.

  1. Digital signalling would enforce the precise timekeeping needed.
  2. Much of the Oxford and Paddington section would be up to speeds of at least 125 mph.
  3. Times in the Central Tunnel of the Elizabeth Line would be identical to the current Class 345 trains.
  4. Much of the Stratford and Southend section would be up to speeds of at least 100 mph.

I estimate that total time would be a few minutes under two hours.

Connecting To The Central Tunnel Of The Elizabeth Line At Royal Oak

I discuss this in Extending The Elizabeth Line – Connecting Great Western Main Line Services To The Central Tunnel.

Connecting To The Central Tunnel Of The Elizabeth Line At Stratford

I discuss this in Extending The Elizabeth Line – Connecting Great Eastern Main Line Services To The Central Tunnel.

 

 

Connecting To The Central Tunnel Of The Elizabeth Line At Abbey Wood

This map from cartometro.com shows the track layout at Abbey Wood.

Note.

  1. The Elizabeth Line is shown in purple.
  2. The North Kent Line is shown in black.
  3. The North Kent Line platform to London is the Southernmost platform and is numbered 1.
  4. The North Kent Line platform from London is the other Southern platform and is numbered 2.
  5. The Elizabeth Line platforms are numbered 3 and 4.
  6. Platform 4 is the Northernmost platform.

At present the Elizabeth Line service to Abbey Wood station is twelve tph, with each platform handling six tph.

This picture shows trains in both Platform 3 and 4 looking towards the station buildings.

Note.

  1. Platform 3 is on the right.
  2. Platform 4 is on the left.

In Elizabeth Line To Ebbsfleet Extension Could Cost £3.2 Billion, I talk about this proposal as described in this article on Ian Visits.

One of the key features of Crossrail To Ebbsfleet (C2E) project is that instead of all trains terminating at Abbey Wood, trains will terminate as follows.

  • Abbey Wood – 4 tph
  • Northfleet – 4 tph
  • Gravesend – 4 tph

This will mean that 8 tph would pass through Abbey Wood station.

  • Platform 4 could certainly handle the four that terminated on the Elizabeth Line.
  • Platform 3 would need to handle eight tph in both directions or sixteen tph to fulfil the proposed C2E service.
  • This would be one train every 225 seconds.

I believe that digital signalling could handle this easily and safely.

I am fairly sure that the track layout at Abbey Wood allows eight tph to go both ways between the North Kent Line and the Elizabeth Line Central Tunnel.

The Maximum Capacity At Abbey Wood Station

Because of the current track layout at Abbey Wood, I believe that without track modifications, Abbey Wood station will not be able to handle more than 12 tph.

Thameslink

These proposed trains would also be compatible with Thameslink, as this route has no platform edge doors.

No platform extensions would be needed, as the Class 345 trains are shorter than the 12-car Class 700 trains.

If they were 125 mph trains, then this would ease timetabling on the East Coast Main Line, as the trains could mix it with the expresses on the fast lines.

Could These High Speed Trains For The Elizabeth Line Have A Cruising Speed Of 140 mph?

It is likely, when full authority digital ERTMS signalling is installed on main lines out of London, that 140 mph will be possible on some at least these routes.

  • East Coast Main Line
  • Great Western Main Line
  • Midland Main Line
  • West Coast Main Line

The extra speed would maximise capacity.

The New Winslow Station Site

This Google Map shows the site of the new Winslow station, on the East West Railway.

Note.

  1. The line from north of Wolvercote Tunnel (just north of Oxford) through Bicester to Bletchley would be enabled for 100 mph (160 km/h) double-track running.
  2. There will be two platforms at Winslow station.
  3. The station is planned to open in 2024.

Services at the station are likely to be.

  • Two tph – Oxford and Milton Keynes via Oxford Parkway, Bicester Village, Winslow and Bletchley
  • One tph – Oxford and Bedford via Oxford Parkway, Bicester Village, Winslow, Bletchley, Woburn Sands and Ridgmont

Note.

  1. tph is trains per hour.
  2. It appears the current Bedford and Bletchley service will continue.

It looks like the one tph service between Aylesbury and Milton Keynes via Aylesbury Vale Parkway, Winslow, Bletchley has been deferred indefinitely.

Consider.

  • Building a single track railway between Aylesbury Vale Parkway station and Claydon Junction on the East West Railway can’t be that challenging or expensive.
  • A single track railway should be able to handle the required train service of up to two tph at Aylesbury Vale Parkway station and occasional freight trains.

It doesn’t look too difficult or costly. So why? The only valid reason I can think of is that High Speed Two doesn’t want it for some reason.

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.

The Route Map Of The East West Main Line

This image shows a schematic map of the East West Main Line.

Note.

  1. There is a lot of detail at the Eastern end. Is that the East Anglia influence in the Partnership?
  2. Bury St. Edmunds has been missed out. Is that the Ipswich influence in the Partnership?
  3. Of the four new stations only Winslow is not in Cambridgeshire. Is that the Cambridge influence in the Partnership?

It should also be noted that there are two links at the East, to the two ports of Freeport East; Felixstowe and Harwich.

Conclusion

This map makes a bold statement.

Will Hitachi Announce A High Speed Metro Train?

As the UK high speed rail network increases, we are seeing more services and proposed services, where local services are sharing tracks, where trains will be running at 125 mph or even more.

London Kings Cross And Cambridge/Kings Lynn

This Great Northern service is run by Class 387 trains.

  • Services run between London Kings Cross and King’s Lynn or Cambridge
  • The Class 387 trains have a maximum operating speed of 110 mph.
  • The route is fully electrified.
  • The trains generally use the fast lines on the East Coast Main Line, South of Hitchin.
  • Most trains on the fast lines on the East Coast Main Line are travelling at 125 mph.

When in the future full digital in-cab ERTMS signalling is implemented on the East Coast Main Line, speeds of up to 140 mph should be possible in some sections between London Kings Cross and Hitchin.

The Digswell Viaduct Problem

I also believe that digital signalling may be able to provide a solution to the twin-track bottleneck over the Digswell Viaduct.

Consider.

  • Airliners have been flown automatically and safely from airport to airport for perhaps four decades.
  • The Victoria Line in London, has been running automatically and safely at over twenty trains per hour (tph) for five decades. It is now running at over 30 tph.
  • I worked with engineers developing a high-frequency sequence control system for a complicated chemical plant in 1970.

We also can’t deny that computers are getting better and more capable.

For these reasons, I believe there could be an ERTMS-based solution to the problem of the Digswell Viaduct, which could be something like this.

  • All trains running on the two track section over the Digswell Viaduct and through Welwyn North station would be under computer control between Welwyn Garden City and Knebworth stations.
  • Fast trains would be slowed as appropriate to create spaces to allow the slow trains to pass through the section.
  • The train drivers would be monitoring the computer control, just as they do on the Victoria Line.

Much more complicated automated systems have been created in various applications.

The nearest rail application in the UK, is probably the application of digital signalling to London Underground’s Circle, District, Hammersmith & City and Metropolitan Lines.

This is known at the Four Lines Modernisation and it will be completed by 2023 and increase capacity by up to twenty-seven percent.

I don’t think it unreasonable to see the following maximum numbers of services running over the Digswell Viaduct by 2030 in both directions in every hour.

  • Sixteen fast trains
  • Four slow trains

That is one train every three minutes.

Currently, it appears to be about ten fast and two slow.

As someone, who doesn’t like to be on a platform, when a fast train goes through, I believe that some form of advanced safety measures should be installed at Welwyn North station.

It would appear that trains between London Kings Cross and King’s Lynn need to have this specification.

  • Ability to run at 125 mph on the East Coast Main Line
  • Ability to run at 140 mph on the East Coast Main Line, under control of full digital in-cab ERTMS signalling.

This speed increase could reduce the journey time between London Kings Cross and Cambridge to just over half-an-hour with London Kings Cross and King’s Lynn under ninety minutes.

The only new infrastructure needed would be improvements to the Fen Line to King’s Lynn to allow two tph, which I think is needed.

Speed improvements between Hitchin and Cambridge could also benefit timings.

London Kings Cross And Cambridge/Norwich

I believe there is a need for a high speed service between London Kings Cross and Norwich via Cambridge.

  • The Class 755 trains, that are capable of 100 mph take 82 minutes, between Cambridge and Norwich.
  • The electrification gap between Ely and Norwich is 54 miles.
  • Norwich station and South of Ely is fully electrified.
  • Greater Anglia’s Norwich and Cambridge service has been very successful.

With the growth of Cambridge and its incessant need for more space, housing and workers, a high speed train  between London Kings Cross and Norwich via Cambridge could tick a lot of boxes.

  • If hourly, it would double the frequency between Cambridge and Norwich until East-West Rail is completed.
  • All stations between Ely and Norwich get a direct London service.
  • Cambridge would have better links for commuting to the city.
  • Norwich would provide the quality premises, that Cambridge is finding hard to develop.
  • London Kings Cross and Cambridge would be just over half an hour apart.
  • If the current London Kings Cross and Ely service were to be extended to Norwich, no extra paths on the East Coast Main Line would be needed.
  • Trains could even split and join at Cambridge or Ely to give all stations a two tph service to London Kings Cross.
  • No new infrastructure would be required.

The Cambridge Cruiser would become the Cambridge High Speed Cruiser.

London Paddington And Bedwyn

This Great Western Railway service is run by Class 802 trains.

  • Services run between London Paddington and Bedwyn.
  • Services use the Great Western Main Line at speeds of up to 125 mph.
  • In the future if full digital in-cab ERTMS signalling is implemented, speeds of up to 140 mph could be possible on some sections between London Paddington and Reading.
  • The 13.3 miles between Newbury and Bedwyn is not electrified.

As the service would need to be able to run both ways between Newbury and Bedwyn, a capability to run upwards of perhaps thirty miles without electrification is needed. Currently, diesel power is used, but battery power would be better.

London Paddington And Oxford

This Great Western Railway service is run by Class 802 trains.

  • Services run between London Paddington and Oxford.
  • Services use the Great Western Main Line at speeds of up to 125 mph.
  • In the future if full digital in-cab ERTMS signalling is implemented, speeds of up to 140 mph could be possible on some sections between London Paddington and Didcot Parkway.
  • The 10.3 miles between Didcot Parkway and Oxford is not electrified.

As the service would need to be able to run both ways between Didcot Parkway and Oxford, a capability to run upwards of perhaps thirty miles without electrification is needed. Currently, diesel power is used, but battery power would be better.

Local And Regional Trains On Existing 125 mph Lines

In The UK, in addition to High Speed One and High Speed Two, we have the following lines, where speeds of 125 mph are possible.

  • East Coast Main Line
  • Great Western Main Line
  • Midland Main Line
  • West Coast Main Line

Note.

  1. Long stretches of these routes allow speeds of up to 125 mph.
  2. Full digital in-cab ERTMS signalling is being installed on the East Coast Main Line to allow running up to 140 mph.
  3. Some of these routes have four tracks, with pairs of slow and fast lines, but there are sections with only two tracks.

It is likely, that by the end of the decade large sections of these four 125 mph lines will have been upgraded, to allow faster running.

If you have Hitachi and other trains thundering along at 140 mph, you don’t want dawdlers, at 100 mph or less, on the same tracks.

These are a few examples of slow trains, that use two-track sections of 125 nph lines.

  • East Midlands Railway – 1 tph – Leicester and Lincoln – Uses Midland Main Line
  • East Midlands Railway – 1 tph – Liverpool and Norwich – Uses Midland Main Line
  • East Midlands Railway – 2 tph – St. Pancras and Corby – Uses Midland Main Line
  • Great Western Railway – 1 tph – Cardiff and Portsmouth Harbour – Uses Great Western Main Line
  • Great Western Railway – 1 tph – Cardiff and Taunton – Uses Great Western Main Line
  • Northern – 1 tph – Manchester Airport and Cumbria – Uses West Coast Main Line
  • Northern – 1 tph – Newcastle and Morpeth – Uses East Coast Main Line
  • West Midlands Trains – Some services use West Coast Main Line.

Conflicts can probably be avoided by judicious train planning in some cases, but in some cases trains capable of 125 mph will be needed.

Southeastern Highspeed Services

Class 395 trains have been running Southeastern Highspeed local services since 2009.

  • Services run between London St. Pancras and Kent.
  • Services use Speed One at speeds of up to 140 mph.
  • These services are planned to be extended to Hastings and possibly Eastbourne.

The extension would need the ability to run on the Marshlink Line, which is an electrification gap of 25.4 miles, between Ashford and Ore.

Thameslink

Thameslink is a tricky problem.

These services run on the double-track section of the East Coast Main Line over the Digswell Viaduct.

  • 2 tph – Cambridge and Brighton – Fast train stopping at Hitchin, Stevenage and Finsbury Park.
  • 2 tph – Cambridge and Kings Cross – Slow train stopping at Hitchin, Stevenage, Knebworth, Welwyn North, Welwyn Garden City, Hatfield, Potters Bar and Finsbury Park
  • 2 tph – Peterborough and Horsham – Fast train stopping at Hitchin, Stevenage and Finsbury Park.

Note.

  1. These services are run by Class 700 trains, that are only capable of 100 mph.
  2. The fast services take the fast lines South of the Digswell Viaduct.
  3. South of Finsbury Park, both fast services cross over to access the Canal Tunnel for St, Pancras station.
  4. I am fairly certain, that I have been on InterCity 125 trains running in excess of 100 mph in places between Finsbury Park and Stevenage.

It would appear that the slow Thameslink trains are slowing express services South of Stevenage.

As I indicated earlier, I think it is likely that the Kings Cross and King’s Lynn services will use 125 mph trains for various reasons, like London and Cambridge in under half an hour.

But if 125 mph trains are better for King’s Lynn services, then they would surely improve Thameslink and increase capacity between London and Stevenage.

Looking at average speeds and timings on the 25 miles between Stevenage and Finsbury Park gives the following.

  • 100 mph – 15 minutes
  • 110 mph – 14 minutes
  • 125 mph – 12 minutes
  • 140 mph – 11 minutes

The figures don’t appear to indicate large savings, but when you take into account that the four tph running the Thameslink services to Peterborough and Cambridge stop at Finsbury Park and Stevenage and have to get up to speed, I feel that the 100 mph Class 700 trains are a hindrance to more and faster trains on the Southern section of the East Coast Main Line.

It should be noted, that faster trains on these Thameslink services would probably have better acceleration and and would be able to execute faster stops at stations.

There is a similar less serious problem on the Midland Main Line branch of Thameslink, in that some Thameslink services use the fast lines.

A couple of years ago, I had a very interesting chat with a group of East Midlands Railway drivers. They felt that the 100 mph Thameslink and the 125 mph Class 222 trains were not a good mix.

The Midland Main Line services are also becoming more complicated, with the new EMR Electric services between St. Pancras and Corby, which will be run by 110 mph Class 360 trains.

Hitachi’s Three Trains With Batteries

Hitachi have so far announced three battery-electric trains. Two are based on battery packs being developed and built by Hyperdrive Innovation.

Hyperdrive Innovation

Looking at the Hyperdrive Innovation web site, I like what I see.

Hyperdrive Innovation provided the battery packs for JCB’s first electric excavator.

Note that JCB give a five-year warranty on the Hyperdrive batteries.

Hyperdrive have also been involved in the design of battery packs for aircraft push-back tractors.

The battery capacity for one of these is given as 172 kWh and it is able to supply 34 kW.

I was very surprised that Hitachi didn’t go back to Japan for their batteries, but after reading Hyperdrive’s web site about the JCB and Textron applications, there would appear to be good reasons to use Hyperdrive.

  • Hyperdrive have experience of large lithium ion batteries.
  • Hyperdrive have a design, develop and manufacture model.
  • They seem to able to develop solutions quickly and successfully.
  • Battery packs for the UK and Europe are made in Sunderland.
  • Hyperdrive are co-operating with Nissan, Warwick Manufacturing Group and Newcastle University.
  • They appear from the web site to be experts in the field of battery management, which is important in prolonging battery life.
  • Hyperdrive have a Taiwanese partner, who manufactures their battery packs for Taiwan and China.
  • I have done calculations based on the datasheet for their batteries and Hyperdrive’s energy density is up with the best

I suspect, that Hitachi also like the idea of a local supplier, as it could be helpful in the negotiation of innovative applications. Face-to-face discussions are easier, when you’re only thirty miles apart.

Hitachi Regional Battery Train

The first train to be announced was the Hitachi Regional Battery Train, which is described in this Hitachi infographic.

Note.

  1. It is only a 100 mph train.
  2. The batteries are to be designed and manufactured by Hyperdrive Innovation.
  3. It has a range of 56 miles on battery power.
  4. Any of Hitachi’s A Train family like Class 800, 802 or 385 train can be converted to a Regional Battery Train.

No orders have been announced yet.

But it would surely be very suitable for routes like.

  • London Paddington And Bedwyn
  • London Paddington And Oxford

It would also be very suitable for extensions to electrified suburban routes like.

  • London Bridge and Uckfield
  • London Waterloo and Salisbury
  • Manchester Airport and Windermere.
  • Newcastle and Carlisle

It would also be a very sound choice to extend electrified routes in Scotland, which are currently run by Class 385 trains.

Hitachi InterCity Tri-Mode Battery Train

The second train to be announced was the Hitachi InterCity Tri-Mode Battery Train, which is described in this Hitachi infographic.

Note.

  1. Only one engine is replaced by a battery.
  2. The batteries are to be designed and manufactured by Hyperdrive Innovation.
  3. Typically a five-car Class 800 or 802 train has three diesel engines and a nine-car train has five.
  4. These trains would obviously be capable of 125 mph on electrified main lines and 140 mph on lines fully equipped with digital in-cab ERTMS signalling.

Nothing is said about battery range away from electrification.

Routes currently run from London with a section without electrification at the other end include.

  • London Kings Cross And Harrogate – 18.3 miles
  • London Kings Cross And Hull – 36 miles
  • London Kings Cross And Lincoln – 16.5 miles
  • London Paddington And Bedwyn – 13.3 miles
  • London Paddington And Oxford – 10.3 miles

In the March 2021 Edition of Modern Railways, LNER are quoted as having aspirations to extend the Lincoln service to Cleethorpes.

  • With all energy developments in North Lincolnshire, this is probably a good idea.
  • Services could also call at Market Rasen and Grimsby.
  • Two trains per day, would probably be a minimum frequency.

But the trains would need to be able to run around 64 miles each way without electrification. Very large batteries and/or charging at Cleethorpes will be needed.

Class 803 Trains For East Coast Trains

East Coast Trains have ordered a fleet of five Class 803 trains.

  • These trains appear to be built for speed and fast acceleration.
  • They have no diesel engines, which must save weight and servicing costs.
  • But they will be fitted with batteries for emergency power to maintain onboard  train services in the event of overhead line failure.
  • They are planned to enter service in October 2021.

Given that Hyperdrive Innovation are developing traction batteries for the other two Hitachi battery trains, I would not be the least bit surprised if Hyperdrive were designing and building the batteries for the Class 803 trains.

  • Hyperdrive batteries are modular, so for a smaller battery you would use less modules.
  • If all coaches are wired for a diesel engine, then they can accept any power module like a battery or hydrogen pack, without expensive redesign.
  • I suspect too, that the battery packs for the Class 803 trains could be tested on an LNER Class 801 train.

LNER might also decide to replace the diesel engines on their Class 801 trains with an emergency battery pack, if it were more energy efficient and had a lighter weight.

Thoughts On The Design Of The Hyperdrive innovation Battery Packs

Consider.

  • Hitachi trains have a sophisticated computer system, which on start-up can determine the configuration of the train or whether it is more than one train running as a longer formation or even being hauled by a locomotive.
  • To convert a bi-mode Class 800 train to an all-electric Class 801 the diesel engines are removed. I suspect that the computer is also adjusted, but train formation may well be totally automatic and independent of the driver.
  • Hyperdrive Innovation’s battery seem to be based on a modular system, where typical modules have a capacity of 5 kWh, weighs 32 Kg and has a volume of 0.022 cu metres.
  • The wet mass of an MTU 16V 1600 R80L diesel engine commonly fitted to AT-300 trains of different types is 6750 Kg or nearly seven tonnes.
  • The diesel engine has a physical size of 1.5 x 1.25 x 0.845 metres, which is a volume of 1.6 cubic metres.
  • In How Much Power Is Needed To Run A Train At 125 mph?, I calculated that a five-car Class 801 electric train, needed 3.42 kWh per vehicle-mile to maintain 125 mph.
  • It is likely, than any design of battery pack, will handle the regenerative braking.

To my mind, the ideal solution would be a plug compatible battery pack, that the train’s computer thought was a diesel engine.

But then I have form in the area of plug-compatible electronics.

At the age of sixteen, for a vacation job, I worked in the Electronics Laboratory at Enfield Rolling Mills.

It was the early sixties and one of their tasks was at the time replacing electronic valve-based automation systems with new transistor-based systems.

The new equipment had to be compatible to that which it replaced, but as some were installed in dozens of places around the works, they had to be able to be plug-compatible, so that they could be quickly changed. Occasionally, the new ones suffered infant-mortality and the old equipment could just be plugged back in, if there wasn’t a spare of the new equipment.

So will Hyperdrive Innovation’s battery-packs have the same characteristics as the diesel engines that they replace?

  • Same instantaneous and continuous power output.
  • Both would fit the same mountings under the train.
  • Same control and electrical power connections.
  • Compatibility with the trains control computer.

I think they will as it will give several advantages.

  • The changeover between diesel engine and battery pack could be designed as a simple overnight operation.
  • Operators can mix-and-match the number of diesel engines and battery-packs to a given route.
  • As the lithium-ion cells making up the battery pack improve, battery capacity and performance can be increased.
  • If the computer, is well-programmed, it could reduce diesel usage and carbon-emissions.
  • Driver conversion from a standard train to one equipped with batteries, would surely be simplified.

As with the diesel engines, all battery packs could be substantially the same across all of Hitachi’s Class 80x trains.

What Size Of Battery Would Be Possible?

If Hyperdrive are producing a battery pack with the same volume as the diesel engine it replaced, I estimate that the battery would have a capacity defined by.

5 * 1.6 / 0.022 = 364 kWh

In an article in the October 2017 Edition of Modern Railways, which is entitled Celling England By The Pound, Ian Walmsley says this in relation to trains running on the Uckfield Branch, which is not very challenging.

A modern EMU needs between 3 and 5 kWh per vehicle mile for this sort of service.

As a figure of 3.42 kWh per vehicle-mile to maintain 125 mph, applies to a Class 801 train, I suspect that a figure of 3 kWh or less could apply to a five-car Class 800 train trundling at around 80-100 mph to Bedwyn, Cleethorpes or Oxford.

  • A one-battery five-car train would have a range of 24.3 miles
  • A two-battery five-car train would have a range of 48.6 miles
  • A three-battery five-car train would have a range of 72.9 miles

Note.

  1. Reducing the consumption to 2.5 kWh per vehicle-mile would give a range of 87.3 miles.
  2. Reducing the consumption to 2 kWh per vehicle-mile would give a range of 109.2 miles.
  3. Hitachi will be working to reduce the electricity consumption of the trains.
  4. There will also be losses at each station stop, as regenerative braking is not 100 % efficient.

But it does appear to me, that distances of the order of 60-70 miles would be possible on a lot of routes.

Bedwyn, Harrogate, Lincoln and Oxford may be possible without charging before the return trip.

Cleethorpes and Hull would need a battery charge before return.

A Specification For A High Speed Metro Train

I have called the proposed train a High Speed Metro Train, as it would run at up to 140 mph on an existing high speed line and then run a full or limited stopping service to the final destination.

These are a few thoughts.

Electrification

In some cases like London Kings Cross and King’s Lynn, the route is already electrified and batteries would only be needed for the following.

  • Handling regenerative braking.
  • Emergency  power in case of overhead line failure.
  • Train movements in depots.

But if the overhead wires on a branch line. are in need of replacement, why not remove them and use battery power? It might be the most affordable and least disruptive option to update the power supply on a route.

The trains would have to be able to run on both types of electrification in the UK.

  • 25 KVAC overhead.
  • 750 VDC third rail.

This dual-voltage capability would enable the extension of Southeastern Highspeed services.

Operating Speed

The trains must obviously be capable of running at the maximum operating speed on the routes they travel.

  • 125 mph on high speed lines, where this speed is possible.
  • 140 mph on high speed lines equipped with full digital in-cab ERTMS signalling, where this speed is possible.

The performance on battery power must be matched with the routes.

Hitachi have said, that their Regional Battery trains can run at up to 100 mph, which would probably be sufficient for most secondary routes in the UK and in line with modern diesel and electric multiple units.

Full Digital In-cab ERTMS Signalling

This will be essential and is already fitted to some of Hitachi’s trains.

Regenerative Braking To Batteries

Hitachi’s battery electric  trains will probably use regenerative braking to the batteries, as it is much more energy efficient.

It also means that when stopping at a station perhaps as much as 70-80% of the train’s kinetic energy can be captured in the batteries and used to accelerate the train.

In Kinetic Energy Of A Five-Car Class 801 Train, I showed that at 125 mph the energy of a full five-car train is just over 100 kWh, so batteries would not need to be unduly large.

Acceleration

This graph from Eversholt Rail, shows the acceleration and deceleration of a five-car Class 802 electric train.

As batteries are just a different source of electric power, I would think, that with respect to acceleration and deceleration, that the performance of a battery-electric version will be similar.

Although, it will only achieve 160 kph instead of the 200 kph of the electric train.

I estimate from this graph, that a battery-electric train would take around 220 seconds from starting to decelerate for a station to being back at 160 kph. If the train was stopped for around eighty seconds, a station stop would add five minutes to the journey time.

London Kings Cross And Cleethorpes

As an example consider a service between London Kings Cross and Cleethorpes.

  • The section without electrification between Newark and Cleethorpes is 64 miles.
  • There appear to be ambitions to increase the operating speed to 90 mph.
  • Local trains seem to travel at around 45 mph including stops.
  • A fast service between London Kings Cross and Cleethorpes would probably stop at Lincoln Central, Market Rasen and Grimsby Town.
  • In addition, local services stop at Collingham, Hykeham, Barnetby and Habrough.
  • London Kings Cross and Newark takes one hour and twenty minutes.
  • London Kings Cross and Cleethorpes takes three hours and fifteen minutes with a change at Doncaster.

I can now calculate a time between Kings Cross and Cleethorpes.

  • If a battery-electric train can average 70 mph between Newark and Cleethorpes, it would take 55 minutes.
  • Add five minutes for each of the three stops at Lincoln Central, Market Rasen and Grimsby Town
  • Add in the eighty minutes between London Kings Cross and Newark and that would be  two-and-a-half hours.

That would be very marketing friendly and a very good start.

Note.

  1. An average speed of 80 mph would save seven minutes.
  2. An average speed of 90 mph would save twelve minutes.
  3. I suspect that the current bi-modes would be slower by a few minutes as their acceleration is not as potent of that of an electric train.

I have a feeling London Kings Cross and Cleethorpes via Lincoln Central, Market Rasen and Grimsby Town, could be a very important service for LNER.

Interiors

I can see a new lightweight and more energy efficient interior being developed for these trains.

In addition some of the routes, where they could be used are popular with cyclists and the current Hitachi trains are not the best for bicycles.

Battery Charging

Range On Batteries

I have left this to last, as it depends on so many factors, including the route and the quality of the driving or the Automatic Train Control

Earlier, I estimated that a five-car train with all three diesel engines replaced by batteries, when trundling around Lincolnshire, Oxfordshire or Wiltshire could have range of up to 100 miles.

That sort of distance would be very useful and would include.

  • Ely and Norwich
  • Newark and Cleethorpes
  • Salisbury and Exeter

It might even allow a round trip between the East Coast Main Line and Hull.

The Ultimate Battery Train

This press release from Hitachi is entitled Hitachi And Eversholt Rail To Develop GWR Intercity Battery Hybrid Train – Offering Fuel Savings Of More Than 20%.

This is a paragraph.

The projected improvements in battery technology – particularly in power output and charge – create opportunities to replace incrementally more diesel engines on long distance trains. With the ambition to create a fully electric-battery intercity train – that can travel the full journey between London and Penzance – by the late 2040s, in line with the UK’s 2050 net zero emissions target.

Consider.

  • Three batteries would on my calculations give a hundred mile range.
  • Would a train with no diesel engines mean that fuel tanks, radiators and other gubbins could be removed and more or large batteries could be added.
  • Could smaller batteries be added to the two driving cars?
  • By 2030, let alone 2040, battery energy density will have increased.

I suspect that one way or another these trains could have a range on battery power of between 130 and 140 miles.

This would certainly be handy in Scotland for the two routes to the North.

  • Haymarket and Aberdeen, which is 130 miles without electrification.
  • Stirling and Inverness, which is 111 miles without electrification, if the current wires are extended from Stirling to Perth, which is being considered by the Scottish Government.

The various sections of the London Paddington to Penzance route are as follows.

  • Paddington and Newbury – 53 miles – electrified
  • Newbury and Taunton – 90 miles – not electrified
  • Taunton and Exeter – 31 miles – not electrified
  • Exeter and Plymouth – 52 miles – not electrified
  • Plymouth and Penzance – 79 miles – not electrified

The total length of the section without electrification between Penzance and Newbury  is a distance of 252 miles.

This means that the train will need a battery charge en route.

I think there are three possibilities.

  • Trains can take up to seven minutes for a stop at Plymouth. As London and Plymouth trains will need to recharge at Plymouth before returning to London, Plymouth station could be fitted with comprehensive recharge facilities for all trains passing through. Perhaps the ideal solution would be to electrify all lines and platforms at Plymouth.
  • Between Taunton and Exeter, the rail line runs alongside the M5 motorway. This would surely be an ideal section to electrify, as it would enable battery electric trains to run between Exeter and both Newbury and Bristol.
  • As some trains terminate at Exeter, there would probably need to be charging facilities there.

I believe that the date of the late 2040s is being overly pessimistic.

I suspect that by 2040 we’ll be seeing trains between London and Aberdeen, Inverness and Penzance doing the trips without a drop of diesel.

But Hitachi are making a promise of London and Penzance by zero-carbon trains, by the late-2040s, because they know they can keep it.

And Passengers and the Government won’t mind the trains being early!

Conclusion

This could be a very useful train to add to Hitachi’s product line.

The Hitachi Intercity Tri-Mode Battery Train Between Paddington And Bedwyn

This is probably one of the easiest services for GWR to run using a Hitachi Intercity Tri-Mode Battery Train.

This Hitachi infographic shows the specification.

Consider.

  • The route is fully electrified between London Paddington and Newbury.
  • It is 13.3 miles between Bedwyn and Newbury, with two intermediate stations.
  • There is under thirty miles without electrification in a round trip between Paddington and Bedwyn.
  • There is a turnback siding at Bedwyn, that could be fitted with a charger if required.
  • Current trains take 17 minutes for between Bedwyn and Newbury, which is an average speed of 47 mph.
  • The trains would run at up to 125 mph between Paddington and Reading.
  • If the Great Western Main Line gets full in-cab digital ERTMS digital signalling, they will be able to take advantage and run at up to 140 mph between Reading and Paddington.

If it could be shown to be able to run the route reliably, I feel that a Hitachi Intercity Tri-Mode Battery Train with a mix of diesel engines and battery packs might be the ideal train.

  • Large amounts of power would not be needed to maintain an average speed of 47 mph between Newbury and Bedwyn, which from my helicopter appears to be a fairly level railway by the side of the Kennett and Avon Canal.
  • Except in emergencies, I doubt that diesel running would be needed.

On my list of possible services for these trains, they would also be able to work GWR services between Paddington and Oxford or any other station with a less than thirty mile round trip away from the electrification

East West Railway Company To Start Second Phase Of Rolling Stock Procurement

The title of this post, is the same as that of this press release from East West Rail.

These are the three introductory paragraphs.

East West Railway Company (EWR Co) is to restart market engagement with potential train suppliers, as its rolling stock procurement process enters a new phase.

The move follows an initial phase of procurement activity, which EWR Co concluded earlier in the year. A new PIN Notice has been published today to restart engagement with potential suppliers, which includes a set of technical specifications taking account of feedback from the market gained during the initial procurement phase.

This procurement aims to secure a short-term, interim solution to leasing a small fleet of self-powered trains for the Western Section of East West Rail.

The press release has a link to the Prior Information Notice or PIN Notice on the EU database.

along with all the usual contact and other details, this is said about the specification.

The East West Railway Company (EWR Co.) is looking to leasing a fleet of 12 or 14 x 3 car self-powered units with modifications including European Train Control System (‘ETCS’) Level 2 and Driver Controlled Operation (‘DCO’) capability, supported by a full maintenance package (under a ‘wet’ lease). These units will ensure timely operation of EWR’s Western Section Phase 2 between Oxford, Milton Keynes, Bedford and Aylesbury. The lease duration would be 4 years, with an option to extend for 2 years.

The date of the notice is the 10th of November 2020, so it has been recently updated.

I commented on these trains in March 2020, when I wrote EWR Targets Short-Term Fleet Ahead Of Possible Electrification.

In the intervening eight months, a lot have things have happened.

Awareness Of Green Issues

The Covid-19 pandemic has arrived, with all its ferocity and seems to be moving people in the direction of thinking about green issues and zero-carbon transport.

Type “build back greener UK” into Google and you get lots of articles. Some feature Boris Johnson, like this article on Business Green, which is entitled Boris Johnson To Pledge To ‘Build Back Greener’.

I don’t think the public, myriad engineers and scientists and a good selection of politicians will find it appropriate for the East West Railway to use any rolling stock, that is not zero-carbon and powered by renewable energy.

Hitachi Have Launched The Regional Battery Train In Conjunction With Hyperdrive Innovation

In July 2020, I wrote Hyperdrive Innovation And Hitachi Rail To Develop Battery Tech For Trains.

Hitachi had been talking for some time, that they were developing battery electric trains for the UK, but this was the first news of a route to their design, manufacture and into service.

Hitachi also published this YouTube video and this infographic of the train’s specification.

They have also called the train, the Hitachi Regional Battery Train.

My estimate is that Oxford and Bedford are under fifty miles apart, so if Hitachi’s train could be charged at both ends of the route, one of their trains could provide a self-powered service between Oxford and Bedford.

It seems that Hitachi have an off-the-shelf train, that fits the specification for the trains required by East West Railway.

Vivarail Have Launched A Fast Charge System

Battery electric trains, like electric vehicles are not much use, if you can’t charge them when it is needed.

The initial Service Pattern of the East West Railway is given in the Wikipedia entry of the East West Railway.

  • Two trains per hour (tph) – Oxford and Milton Keynes Central via Oxford Parkway, Bicester Village, Winslow and Bletchley.
  • One tph – Oxford and Milton Keynes via Oxford Parkway, Bicester Village, Winslow, Bletchley, Woburn Sands and Ridgemont.
  • One tph – Aylesbury and Milton Keynes Central via Aylesbury Vale Parkway, Winslow and Bletchley.

There are four terminal stations.

  • Aylesbury – No electrification
  • Bedford – Full Electrification
  • Milton Keynes Central – Full Electrification
  • Oxford – No electrification

The existing electrification could be used at Bedford and Milton Keynes Central, whereas some type of charging system, would be needed at Aylesbury and Oxford.

It appears that Adrian Shooter of Vivarail has just announced a One-Size-Fits-All Fast Charge system, that has been given interim approval by Network Rail.

I discuss this charger in Vivarail’s Plans For Zero-Emission Trains, which is based on a video on the Modern Railways web site.

There is more about Vivarail’s plans in the November 2020 Print Edition of the magazine, where this is said on page 69.

‘Network Rail has granted interim approval for the fast charge system and wants it to be the UK’s standard battery charging system’ says Mr. Shooter. ‘We believe it could have worldwide implications.’

Vivarail’s Fast Charge system would surely be a front-runner for installation at Aylesbury and Oxford, if battery electric trains were to be run on the East West Railway.

Choosing A Train

East West Rail have said the following about the train specification.

  • Three cars
  • Self-powered
  • European Train Control System (‘ETCS’) Level 2 and Driver Controlled Operation (‘DCO’) capability
  • Available on a wet lease, that includes a full maintenance package

The press release from East West Rail and other documents mentions between twelve and fourteen trains will be leased.

In Trains Needed For The East West Railway, I calculated that the proposed services could need around eight or nine trains.

This must mean one of three things.

  • There are plans for extra services.
  • There are plans for the proposed services to be extended.
  • Trains will run some services in pairs.

Because, of the last reason, the trains must have the ability to run in pairs.

As sections of the East West Railway are being built for 100 mph operation, the trains must also have a 100 mph capability.

When I talked briefly about green issues earlier, I said that I felt the trains should be zero-carbon, which would rule out diesel.

That leaves two options for self-powered operation; battery electric or hydrogen.

So what trains fit the specification?

British Rail Era Trains

A large number of British Rail era trains could be suitable for updating for interim use on the East West Railway.

I even suspect, some fantasist will suggest using shortened versions of InterCity 125 trains, as are used in South-West England and Scotland.

But let’s be serious and not insult the intelligence of the three world-leading universities on the final route of the East West Railway.

A lot of money is also being spent on this railway and tarted-up forty-year-old trains would not encourage people to use the new railway.

Class 170 Trains

There are eighty-seven three-car Class 170 trains with various operators, some of which will be surplus to requirements, as they are being replaced with new trains.

But they are diesel, so surely they don’t fit my perceived need for zero-carbon trains.

That would have been true until a couple of weeks ago, when as I wrote in Vivarail’s Plans For Zero-Emission Trains, Adrian Shooter of Vivarail disclosed an audacious plan to convert, diesel trains into zero-carbon battery electric trains.

Class 170 trains like this were on the list of possible conversions.

  • They 100 mph trains.
  • Some are three-cars.
  • They meet all the disability regulations.
  • They have been used for services much longer than Oxford and Bedford.

They could also start the service as diesel trains and gradually converted to battery electric, if this would be better for operation.

Class 175 Trains

The three-car 100 mph Class 175 trains could be a possibility as there are fifteen trains, but they have two problems.

  • They are powered by diesel.
  • They probably won’t be available until 2023.

So I think they can be ruled out.

Class 185 Trains

All the fifty-one Class 185 trains are currently in service with TransPennine Express. They are due to release fifteen trains in 2021 and it was thought that these trains were in prime position for becoming the interim trains for East West Railway.

  • They 100 mph trains.
  • Some are three-cars.
  • They meet all the disability regulations.
  • They have been used for services much longer than Oxford and Bedford.
  • The fleet is the right size.

But then the Department of Transport decided to change their plans for the Liverpool and Norwich service.

I wrote about one journey on the overcrowded section of this service in Mule Trains Between Liverpool And Norwich.

The picture shows the inadequate train formed of an assorted collection of Class 153 trains, I took from Liverpool to Sheffield.

The service is now being split at Nottingham and East Midlands Railway will receive the released Class 185 trains for the Liverpool and Nottingham portion of the service.

A fleet of these Class 185 trains will surely offer more comfort on a very busy service.

So it is looking unlikely that Class 185 trains will be used on the East West Railway.

Class 220, 221 and 222 Trains

These three fleets of Voyager trains could be a possibility, as they can be shortened to three-car trains.

But they have disadvantages.

I think it is unlikely, that these trains will be used on the East West Railway.

Class 350 Trains

There are thirty-seven Class 350 trains, that were built only twelve years ago, that have been retired. The owner; Porterbrook are planning to convert them into battery electric versions, which they have called BatteryFLEX trains.

Unfortunately, they are four-cars and unlike other trains, it doesn’t appear that they can be shortened to three cars.

Class 375, 377, 379 and 387 Trains

These four fleets of Electrostar trains could be a possibility for running as battery electric trains.

  • Some are three-car trains and four-car trains can be converted to three-car trains, by simply removing a car.
  • They are 100 mph trains.
  • Bombardier converted a Class 379 train for battery operation and I have heard or seen no adverse reports from either passengers, rail staff or journalists.
  • They can work in multiple formations.
  • They are all wired for dual-voltage operation.
  • Pantographs wells have already been fitted to trains that normally work using 750 VDC third-rail electrification.

The picture shows the Class 379 train, that was converted to battery electric operation.

The Class 379 trains, also have the advantage, that there is a fleet of thirty trains, that are being replaced by Greater Anglia, who are homeless.

If I were the owner of the Class 379 trains, I’d do the following.

  • Convert them all into battery electric trains.
  • Shuffle cars around to get a mix of three-, four- and five-car trains to match market opportunities.
  • Make them compatible with Vivarail’s Fast Charge system.
  • Do a licensing deal with Vivarail, so I could supply the chargers.

This plan has some big advantages.

  • Battery electric operation of the Class 379 trains has been successfully proven.
  • Some Class 379 trains are already available for conversion, as they have been replaced by Greater Anglia.
  • The trains could easily be delivered in time for the opening of the East West Railway.
  • The trains would not need to be replaced, if the East West Railway was to be fully electrified in the future.
  • If I leased out all the Class 379 trains, I’m fairly sure that I could acquire some other Electrostars to convert.

The trains would surely be ideal for the Uckfield Branch and Ashford and Hastings, which are to be run by battery electric trains.

  • The order for these services is still to be announced.
  • This use would be a trial application of the highest quality.
  • I suspect that five-car trains would be ideal for these Southern routes.
  • In Battery Electrostars And The Uckfield Branch, I estimated that Southern would need twelve five-car trains for the Uckfield Branch and four trains for the Ashford and Hastings service.

It looks to me, the thirty four-car Class 379 trains could be converted into the following battery electric trains.

  • Twelve five-car trains for the Uckfield Branch.
  • Four four-car trains for Ashford and Hastings.
  • Fourteen three-car trains for the East West Railway.

Using battery electric Class 379 trains for the East West Railway, the Uckfield Branch and Ashford and Hastings. looks from the engineering, numbers and financial points of view to be a very efficient proposition.

Class 385 Trains

As I indicated earlier, Hitachi have the technology to create a Class 385 train with a battery capability.

  • They appear to be talking to ScotRail.
  • Are they talking to Vivarail about using their Fast Charge system?
  • As the trains would be new, East West Railway would get trains to their specification.

Battery electric Class 385 trains must be a serious proposition.

Class 600 Trains

The Class 600 train could be an interesting possibility.

The trains can be powered by both hydrogen and overhead or third-rail electrification.

  • The trains are three-cars long.
  • They are 100 mph trains.
  • First in-service dates are scheduled for 2024, which could be convenient.
  • The trains will have a state-of-the-art Renatus interior.
  • They will not need charging and could probably be refuelled as infrequently as only once per day.

I am not worried, by the train being powered by hydrogen, but because of the large tanks in the train, the passenger capacity will be lower, than a diesel, electric or battery electric train of a similar length.

I suspect though, that Alstom will be pitching for the order.

Aventras

In this article in Global Rail News from 2011, which is entitled Bombardier’s AVENTRA – A new era in train performance, gives some details of the Aventra’s electrical systems. This is said.

AVENTRA can run on both 25kV AC and 750V DC power – the high-efficiency transformers being another area where a heavier component was chosen because, in the long term, it’s cheaper to run. Pairs of cars will run off a common power bus with a converter on one car powering both. The other car can be fitted with power storage devices such as super-capacitors or Lithium-ion batteries if required. The intention is that every car will be powered although trailer cars will be available.

Unlike today’s commuter trains, AVENTRA will also shut down fully at night. It will be ‘woken up’ by remote control before the driver arrives for the first shift

This was published over nine years ago, so I suspect Bombardier have refined the concept.

Bombardier have not announced that any of their trains have energy storage, but I have my suspicions, that both the Class 345 and Class 710 trains use super-capacitors or Lithium-ion batteries, as part of their traction system design.

I believe that Bombardier, have the ability to build an Aventra to this specification.

  • Three-cars
  • 100 mph running
  • Sixty mile range on battery power.
  • Dual voltage.
  • Ability to work in pairs.

Like the Hitachi trains, they would be new build.

CAF

CAF have proposed a battery electric train based on the Class 331 train, which I wrote about in Northern’s Battery Plans.

It is a four-car development of the three-car Class 331 trains.

Can it be built as a three-car train to fit the specification?

Conclusion

There are some good candidates sir supplying an interim fleet of trains for the East West Railway.

My money’s on one of the following.

  • New Hitachi Class 385 trains
  • Converted Class 379 trains.
  • New Aventras

All would be battery electric trains.

But there is a change that Alstom’s Class 600 hydrogen trains could be used.
