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 Crossrail Tracks To The West Of Paddington Station

This map from carto metro, shows the track layout to the West of the Crossrail platforms at Paddington station.

Note.

  1. The Crossrail tunnels are shown in dotted purple at the Eastern end of the map.
  2. The tracks change from purple to black at the Royal Oak tunnel portal.
  3. Two tracks named CRL Eastbound and CRL Westbound appear to pass either side of two turnback sidings.
  4. These tracks change to purple in colour and can be followed to the Western end of the map.
  5. Tracks break off from this route to the North and serve the depot at Old Oak Common.

It appears to be a very clean and simple layout.

Crossrail Formally Hands Paddington Station Over To TfL

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

Ian says this about the current status of the stations.

This is the sixth of the Elizabeth line stations to be transferred over to TfL, following Custom House, Farringdon, Tottenham Court Road, Woolwich and Liverpool Street stations, which leaves only Canary Wharf, Whitechapel and the late running Bond Street to go.

Paddington station certainly looked very ready, when I visited yesterday and took the pictures in The Main Crossrail Entrance At Paddington Station.

The Main Crossrail Entrance At Paddington Station

These pictures show the entrance to Crossrail at Paddington station, which is by Platform 1.

Note.

  1. The whole entrance is under a massive glass roof.
  2. Eastbourne Terrace is above the station and connected to it by stairs and a pair of lifts.
  3. There is a bus stop and short-term parking on Eastbourne Terrace.
  4. There are a large number of escalators between the main line station and the Crossrail level.
  5. There are plenty of seats everywhere.
  6. It is only a short walk between one set of escalators to Crossrail and the shops in the Lawn.

I think Brunel would have liked it, as it has a touch of the over-the-top.

This is a 3D Google Map of the new entrance.

Note.

  1. The cloud pattern on the roof is clearly visible.
  2. The lifts to the station are in the middle and the stairs are at the ends of the roof.
  3. The blue dot shows the position of the bus stop, where about five routes stop.

Will cars and taxis be able to drop people off in Eastbourne Terrace?

Conclusion

It’s an impressive new entrance to the station.

Crossrail’s New Opening Plan

This article on the excellent and well-informed IanVisits is entitled Crossrail Changes Its Staged Opening Plans.

Ian states that Crossrail will be split into two routes.

  • Shenfield and Paddington
  • Abbey Wood and Heathrow/Reading

Frequencies will be reduced, but Ian states there could be two positive benefits.

  • Abbey Wood and Paddington could open earlier in 2022.
  • The full integrated service could be brought forward six months.

Why is this possible?

These are my thoughts.

The Covid-19 Pandemic

The current TfL Rail service between Shenfield and Liverpool Street stations coped well before the pandemic  and now with reduced passenger numbers it is able to handle current passenger loads without a problem.

I have used Crossrail from Paddington to Heathrow and Reading during the pandemic and Crossrail’s nine-car trains are handling passenger numbers with ease.

It would appear to me, that by using two platforms at Liverpool Street and Paddington stations, the benefits of Crossrail have been delivered to the East and West of the massive Greater London conurbation.

Stratford Station

Stratford station is more or less complete with respect to Crossrail.

  • It can handle ten-car trains, if they run in the future.
  • The two dedicated platforms for Crossrail, can probably handle the maximum frequency of trains, the line will ever carry.

But Stratford’s biggest advantage is the connections to the Central and Jubilee Lines, and the North London Line of the London Overground, which between them give access to most of Central and North London.

Ealing Broadway Station

A few weeks ago, a fully step-free Ealing Broadway station opened, as I wrote about in Ealing Broadway Station – 31st May 2021.

As with Stratford station, Ealing Broadway station is ready for any future Crossrail service.

It also has connections to the Central and District Lines to give access to most of Central London.

Can The Underground Cope In Central London?

All Lines except the Northern and Piccadilly Lines have seen improvement to signalling and/or trains in recent years and in my meandering around London, they seem to be coping well with the current passenger levels.

Liverpool Street Station

I use Liverpool Street station regularly and changes are happening at the station.

  • Platforms have been lengthened so that ten-car Crossrail trains can be handled.
  • The main entrance to the Underground was updated a few years ago and has a very wide gateline.
  • A wider gateline is being installed for Crossrail and other suburban services on the East side of Liverpool Street station.
  • A new entrance to Crossrail has been completed in front of Broadgate and appears ready to open, as I observed in Crossrail’s First Inclined Lift Is Now Available To View!.

A second high capacity step-free entrance has opened on Moorgate. When Crossrail opens through Liverpool Street station opens it will enable the following.

Passengers will be able to walk underground between Liverpool Street and Moorgate, with a substantial section of the route up and down escalators. I described the route in detail in London’s First Underground Roller Coaster.

The Crossrail entrance inside the Underground station at Liverpool Street station is now visible.

Note.

  1. Crossrail is behind the two pairs of massive stainless-steel doors.
  2. Peeping through the window, construction appeared to be almost at completion.
  3. If you turn right here, you take the escalator down to the Central Line.

Eventually, Liverpool Street and Moorgate stations could even be considered a single station with a massive escalator connection between the two original stations.

Liverpool Street And Stratford Stations Together Give Crossrail A Comprehensive Under/Overground Connection

These Under/Overground lines connect to either or both stations.

  • Central Line – Connects to both stations, but at Stratford it’s a cross-platform interchange with Crossrail. Ideal for Oxford Street, the City of London and St. Paul’s.
  • Circle Line – Connects to Liverpool Street. Ideal for Euston, Kings Cross, Paddington, St. Pancras, Victoria and large parts of South Central and West London.
  • Hammersmith And City Line – Connects to Liverpool Street. Ideal for Euston, Kings Cross, Paddington, St. Pancras and large parts of West London.
  • Jubilee Line – Connects to Stratford. Ideal for Bond Street, Canary Wharf, London Bridge, Waterloo and Westminster.
  • Lea Valley Lines – These Overground Lines connect to Liverpool Street. Ideal for Enfield, Hackney, Haringey, Waltham Forest and North East London and South East Hertfordshire.
  • Metropolitan Line – Connects to Liverpool Street. Ideal for Euston, Kings Cross, Paddington and St. Pancras, Wembley Stadium and North-West London.
  • North London Line – This Overground Line connects to Stratford. Ideal for Acton, Brent, Dalston, Hackney, Hampstead and a large proportion of North and West London.

Liverpool Street and Stratford certainly have comprehensive connections to the Underground and Overground.

Liverpool Street And Shenfield Is Signalled With TPWS

TPWS is the only signalling system used on the section of Crossrail between Liverpool Street And Shenfield stations.

It offers these benefits, as opposed to the ETCS used in Crossrail’s core tunnel.

  • It eased the replacement of the original Class 315 trains with new Class 345 trains.
  • It allows Crossrail’s trains to share tracks with other trains not fitted with ETCS.
  • Drivers only have to handle one signalling system on the route.

The single signalling system must make commissioning and operating the service between Liverpool Street And Shenfield stations easier.

Liverpool Street Station Gives Crossrail Flexibility In The East

The distance between the two current Crossrail platforms at Liverpool Street station and the steel doors will probably be no more than a couple of minutes walk with just a couple of steps down into the Underground station, which can be by-passed by a lift.

Currently, the service between Liverpool Street and Shenfield station has a frequency of eight trains per hour (tph)

  • These trains are currently nine-cars long.
  • The two Crossrail platforms at Liverpool Street have been lengthened to handle ten-car trains.
  • The gateline for the Crossrail platforms is being improved to handle a higher volume of passengers.

If overcrowding should become a problem between Liverpool Street and Shenfield, then there is a quick fix of adding a tenth car to the trains, which would increase capacity by eleven percent.

The extra cars would be borrowed from Crossrail trains sitting in sidings, that are not needed because of the reduced train frequencies.

When Crossrail opens between Abbey Wood and Paddington stations, passengers needing to go between say Ilford and Paddington will be able to take the short walk between both pairs of Crossrail platforms at Liverpool Street station.

But the big advantage comes, when Crossrail starts running between Shenfield and Paddington.

Trains can be gradually swapped between Liverpool Street and Paddington as a terminus.

If there is a problem in Crossrail’s central tunnel, then services can be swapped back to Crossrail’s two current platforms in the National Rail station.

It looks to be a well-designed system.

Could The Pedestrian Route Between Liverpool Street And Moorgate Stations Be Opened Early?

This article on IanVisits is entitled Northern Line Bank Branch To Close For 4 Months Next Year.

The Northern Line will be closed between Moorgate and Kennington stations from the 15th January to mid-May.

Extra buses will obviously be run between Moorgate and Kennington to help during the closure.

  • Finsbury Square is already used to turn buses and could be used as a Northern terminal.
  • London Bridge has a bus station and could be used to turn buses.
  • In his article Ian talks of buses between Oval and the City.
  • The 21 and 141 bus routes run between Moorgate and London Bridge.

Would opening the pedestrian link help a lot of people by providing an easier route between Bank and Moorgate stations, by using the Central Line to Liverpool Street and then the tunnel?

  • It would be fully step-free.
  • Passengers from say St. Paul’s or Chancery Lane stations on the Central Line needing to get to say Angel station might find it an easier route.
  • The weather isn’t always good enough for a walk.

It would be an escalator connection par excellence.

I suspect that this pedestrian route could open before January 15th.

  • It will obviously need to be open when Crossrail opens between Abbey Wood and Paddington.
  • As a pedestrian route, it will improve connectivity at both Liverpool Street and Moorgate stations.
  • The Crossrail station at Liverpool Street, has been handed over to Transport for London.
  • It could allow the opening up of the step-free tunnel from the Northern and Northern City Lines to the new entrance at Moorgate station.

Could the last point be the most significant, as it would make the Northern Line platforms at Moorgate station fully step-free in time for the blockade between Moorgate and Kennington stations?

As Transport for London have accepted Liverpool Street station, opening of the pedestrian route is surely their sole decision.

Could The Pedestrian Route Between The Bakerloo Line And Crossrail Be Opened Early?

Access to the Bakerloo Line at Paddington is being transformed by two projects.

  • The addition of a step-free pedestrian tunnel, which will be around eighty metres long, that will link the Bakerloo Line and Crossrail.
  • A new step-free entrance and booking hall for the Bakerloo Line,that will replace the current Praed Street entrance.

This page on the Transport for London web site, which is entitled Paddington Bakerloo Ticket Hall, gives more details of the new entrance.

Transport for London indicate that the second project will be completed by mid-2022.

But I do wonder, if after Paddington station is handed over to Transport for London, if this tunnel could be opened to give interim step-free access to the Bakerloo Line, until either Crossrail or the new entrance opens.

When Crossrail and these two projects are completed, will this mean that the Bakerloo Line will see a lot more passengers?

Abbey Wood And Paddington

Crossrail between Abbey Wood And Paddington has the following characteristics.

  • It is a new twin-track railway, that it doesn’t share with other trains.
  • Most of the route is in tunnel, with just three sections on the surface.
  • The route is signalled with ETCS.
  • All new underground stations will have platform-edge doors.

It is very much a railway designed to the highest modern standards.

The Surface Section At Abbey Wood

The surface section at Abbey Wood has these purposes.

  • To provide an interchange station with the North Kent Line.
  • To turn back trains towards the West.
  • To provide stabling for trains and service trains to enable a smooth operation of the Abbey Wood and Paddington section of Crossrail.

This map from cartometro shows the track layout to the East of Plumstead station.

Note.

  1. Crossrail is shown in purple.
  2. Abbey Wood station has two platforms for Crossrail and two for the North Kent Line.
  3. The platforms appear to be numbered one to four from the South.
  4. There appears to be a turnback for Crossrail trains in Platform 3, which also appears to have crossovers to connect to the North Kent Line.
  5. Crossovers to the West of Abbey Wood station allow trains to use either Crossrail platform.
  6. These crossovers also allow access to the sidings at Plumstead.
  7. The Plumstead tunnel portal can be seen below Plumstead Depot.

If Abbey Wood station follows the two National Rail platforms at Liverpool Street in handling a total of 8 tph, then initially Abbey Wood could handle this frequency of trains.

Ian says this in the first article about the frequencies of Crossrail during testing.

Before the blockade, Crossrail was testing the line with an 8 trains per hour (8tph) service, but this week they are going to be ramping that up to 12tph, which will mirror the timetabled service that the line will offer when it opens early next year.

Note that 12 tph will require Abbey Wood station to handle 6 tph on each platform.

Transport for London also intend to simulate 24 tph through the central section, which will be the Peak frequency when the line fully opens.

The Surface Section At Custom House

This map from cartometro shows the track layout around Custom House station.

Note.

  1. Crossrail is shown in purple.
  2. The DLR is shown in light green.
  3. The tunnel portal for the central Crossrail tunnel is to the West of Custom House station.
  4. The tunnel portal for the Connaught tunnel is in the area of the former Connaught Road station.
  5. Between the other end of the Connaught tunnel and Woolwich station, some of the route is in a cutting.
  6. There are crossovers either side of Custom House station.

I suspect a lot of the complications are because an old route was reused.

The Surface Section At Paddington

This map from cartometro shows the track layout around Paddington station.

Note.

  1. The Crossrail station at Paddington is a straight-through two platform station.
  2. The Royal Oak portal, where Crossrail comes to the surface is just to the West of Royal Oak Underground station.
  3. Two lines are labelled CRL Eastbound and CRL Westbound are connected to the Crossrail lines.
  4. Between and around these lines is Paddington New Yard
  5. There are two full crossovers between Paddington New Yard and the Royal Oak portal.

To reverse at Paddington, trains proceed to Paddington New Yard, where the driver changes ends and then returns to Paddington, when needed.

Trains for Reading and Heathrow use the CRL Eastbound and CRL Westbound lines to connect to Crossrail’s Western surface tracks and the Central core tunnel.

It all looks well-designed to my untrained eye.

Platform Edge Doors

This page on the Crossrail web describes the platform edge doors.

This is the first paragraph.

Crossrail has installed floor-to-ceiling platforms screen doors at each of the eight new underground stations on the Elizabeth line – that’s roughly 4 kilometers of platform edge screens in total.

The new stations between Abbey Wood and Paddington are,

  • Paddington
  • Bond Street
  • Tottenham Court Road
  • Farringdon
  • Liverpool Street
  • Whitechapel
  • Canary Wharf
  • Custom House
  • Woolwich

This is eight underground stations and one surface station; Custom House.

So does it mean that Custom House station doesn’t have platform edge doors?

 

I took these pictures of Custom House station today.

Note.

  1. The Crossrail trains were running at a frequency of 8 tph.
  2. , The pictures don’t show any platform edge doors or structures capable of supporting platform edge doors.

Could the regulations allow a surface station like Custom House to be built without doors, or were they left out to save money?

Safety is assured by being able to shut off all entrances to the platforms.

But it does appear that between Custom House and Paddington stations, passengers and trains are separated by platform edge doors.

  • Platform edge doors are controlled by the signalling, so with the correct interlocking a lot of things are possible.
  • Suppose, a station is not ready for passengers, then by locking the doors closed, trains can still pass through.
  • Does this mean that at stations like Liverpool Street, where passengers might need to walk between the Moorgate and Liverpool Street ends of the station to change trains, that these pedestrian routes could be opened? I think it does?

It does appear to me, that platform edge doors are the key to opening a partially-completed railway.

When Could Abbey Wood And Paddington Open?

It strikes me that the following conditions must be met.

  • Paddington station must be handed over to Transport for London.
  • Platform edge doors at all stations must work reliably.
  • The trains must work reliably with the signalling.

It looks like Bond Street, Paddington and Whitechapel stations, are the only stations that have not been handed over to Transport for London.

  • I suspect, as Paddington is a terminal station, it must be handed over.
  • Crossrail have said they could live with Bond Street opening later.
  • Whitechapel appears to have been a difficult station to build, so perhaps it could open later.

Could Crossrail open partially, earlier than anyone thinks?

Perhaps this post called Your First Crossrail Service May Arrive In Time For Christmas, was based on fact and not rumour in the Sunday Times.

800009 – John Charles

On my way to Wales on Tuesday, I travelled in the Class 800 train, that is numbered 800009 and named after the great Welsh footballer; John Charles at one end.

I actually saw him play for Leeds in a match against Spurs at White Hart Lane. Leeds played in a blue kit in those days and I am fairly sure John Charles played up front.

I suspect, it likely, that it must have been the  1956-57 season as it would be the only season where Leeds were in the First Division, before John Charles left in 1957 to go to Juventus.

I wonder how many people, who saw John Charles play, have actually ridden in the train named after him?

It was good to see that Great Western Railway have also put his Italian nickname; Il Gigante Buono on the train.

Thoughts On Train Times Between London Paddington And Cardiff Central

I went to Cardiff from Paddington on Tuesday.

These were the journey details.

  • Distance – Paddington and Cardiff – 145.1 miles
  • Time – Paddington and Cardiff – 110 minutes – 79.1 mph
  • Time – Cardiff and Paddington- 114 minutes – 76.4 mph

There were four stops. Each seemed to take between two and three minutes.

I do feel though, that the trains are still running to a timetable, that could be run by an InterCity 125.

I watched the Speedview app on my phone for a lot of both journeys.

  • There was quite an amount of 125 mph running on the route.
  • Some stretches of the route seemed to be run at a line speed of around 90 mph.
  • The Severn Tunnel appears to have a 90 mph speed.
  • Coming back to London the train ran at 125 mph until the Wharncliffe Viaduct.

These are my thoughts.

Under Two Hour Service

The current service is under two hours, which is probably a good start.

Improving The Current Service

It does strike me that the current timetable doesn’t take full advantage of the performance of the new Hitachi Class 80x trains.

  • Could a minute be saved at each of the four stops?
  • Could more 125 mph running be introduced?
  • Could the trains go faster through the Severn Tunnel?
  • If two trains per hour (tph) were to be restored, would that allow a more efficient stopping pattern?
  • The route has at least four tracks between Paddington and Didcot Parkway and the Severn Tunnel and Cardiff.

I would reckon that times of between one hour and forty minutes and one hour and forty-five minutes are possible.

These times correspond to average speeds of between 87 and 83 mph.

Application of In-Cab Digital Signalling

Currently, a typical train leaving Paddington completes the 45.7 miles between Hanwell and Didcot Parkway with a stop at Reading in 28 minutes, which is an average speed of 97.9 mph.

This busy section of the route is surely an obvious one for In-cab digital signalling., which would allow speeds of up to 140 mph.

  • Services join and leave the route on branches to Bedwyn, Heathrow, Oxford and Taunton.
  • The Heathrow services are run by 110 mph Class 387 trains.
  • There are slow lines for local services and freight trains.

If an average speed of 125 mph could be attained between Hanwell and Didcot Parkway, this would save six minutes on the time.

Would any extra savings be possible on other sections of the route, by using in-cab digital signalling?

I suspect on the busy section between Bristol Parkway and Cardiff Central stations several minutes could be saved.

Would A Ninety Minute Time Between Paddington And Cardiff Be Possible?

To handle the 145.1 miles between Paddington and Cardiff Central would require an average speed including four stops of 96.7 mph.

This average speed is in line with the current time between Hanwell and Didcot Parkway with a stop at Reading, so I suspect that with improvements to the timetable, that a ninety minute service between Paddington and Cardiff Central is possible.

It may or may not need in-cab digital signalling.

My Control Engineer’s nose says that this signalling upgrade will be needed.

Would A Sixty Minute Time Between Paddington And Cardiff Be Possible?

A journey time of an hour between Paddington and Cardiff Central would surely be the dream of all politicians the Great Western Railway and many of those involved with trains.

To handle the 145.1 miles between Paddington and Cardiff Central would require an average speed including four stops of 145.1 mph.

It would probably be difficult to maintain a speed a few mph above the trains current maximum speed for an hour.

  • How many minutes would be saved with perhaps a single intermediate stop at Bristol Parkway station?
  • Perhaps the Cardiff service could be two tph in ninety minutes and one tph in sixty minutes.
  • Full in-cab digital signalling would certainly be needed.
  • Faster trains with a maximum speed of up to 155-160 mph would certainly be needed.
  • There may be a need for some extra tracks in some places on the route.

A journey time of an hour will be a few years coming, but I feel it is an achievable objective.

The Extended Route To Swansea

Cardiff Central and Swansea is a distance of 45.7 miles

A typical service takes 55 minutes with three stops, at an average speed of 49.8 mph.

This would be an ideal route for a Hitachi Intercity Tri-Mode Battery Train, which is described in this Hitachi infographic.

It would probably be needed to be charged at Swansea station, to both enable return to Cardiff Central or extend the service to the West of Swansea.

Conclusion

Big improvements in journey times between Paddington and Cardiff Central are possible.

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.

Are These Two Good News Articles From Crossrail?

This press release from Crossrail is entitled Tottenham Court Road Elizabeth Line Station Enters Final Commissioning Phase.

These are the first three paragraphs.

The Tottenham Court Road Elizabeth line station has reached an important milestone with construction works sufficiently finished for final commissioning activities to start, Crossrail has confirmed.

The station has reached the T-12 landmark, this means the station is now considered to be 12 weeks away from being ready for handover to Transport for London (TfL), who will operate the Elizabeth line.

Work at the station will now primarily focus on the extensive testing and commissioning of systems ahead of the Elizabeth line opening. The railway is still on track to open in the first half of 2022.

This video from Crossrail explains what needs to be done before Trial Running can start.

This article on New Civil Engineer is entitled Crossrail | All But One Central London Station Is ‘Ready For Use’.

These are the first two paragraphs.

All but one of Crossrail’s central London stations has been signed off as “ready for use”, Crossrail chief executive Mark Wild revealed in his latest update to the London Assembly.

Paddington is the only station yet to have its assets assured and certified as ready to enter trial running.

It looks like Crossrail is finally getting there.

Bond Street Station

In both articles there is no mention of Bond Street station, which in many reports has been described as running behind the other stations.

So when the New Civil Engineer article said that only one station wasn’t ready for use, I assumed it was Bond Street, rather than Paddington, as noted in the article.

So has progress at Bond Street station improved? If it has that that would appear to be more good news.

In Your First Crossrail Service May Arrive In Time For Christmas, I was speculating, when I said.

Bond Street station certainly seems to have caught up with the others and there is no longer any suggestion it could open a year later.

Perhaps, I was right.

Conclusion

The news certainly isn’t bad!

ORR Rejects Grand Union’s London Paddington To Cardiff Train Service Bid

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

I wrote about this service in Grand Union Seeks ’91s’ To Cardiff and this was my conclusion.

I like this proposal.

    • The important Paddington and Cardiff route gets a fifty percent increase in train frequency.
    • There could be genuine competition on the route.
    • Grand Union would be using five of the thirty InterCity225 sets, which are in good condition, judging by my recent journeys.
    • Could we see a customer service and catering war between the two operators?

If Grand Union Railway runs to Cardiff, I’ll give it a go.

I can see a revised proposal being successful.
