Chiltern Railways New Trains For Aylesbury
This page on the Chiltern Railways web site, is entitled Chiltern Railways 2030 Vision.
This is an extract from the page.
It covers how investing in our fleet is:
- The Right Route for people by driving forward improvements in punctuality, level of crowding, frequency and seating capacity.
- The Right Route for connections by making it easier for people to travel by train to the places they need to go, and bring people and businesses closer together through a stronger network.
- The Right Route for our environment by reducing carbon emissions and helping customers to use their cars less across our route.
- The Right Route for innovation by helping create jobs and economic activity across our route and the national supply chain.
- The Right Route for the future of our communities by helping reach communities reach their full potential as more people move to towns, villages and cities across the route.
We plan to work closely with the Department for Transport to agree the scope and funding for new trains between London and Aylesbury soon.
These trains run to Aylesbury and/or Aylesbury Vale Parkway stations.
- London Marylebone and Aylesbury via High Wycombe – 43.5 miles (70 km.) – 17 stops
- London Marylebone and Aylesbury via Amersham – 38.8 miles (62.4 km.) – 10 stops
- London Marylebone and Aylesbury Vale Parkway via Amersham – 41.2 miles (66.3.) – 11 stops
- Princes Risborough and Aylesbury – 7.2 miles (11.6 km.) – 2 stops
Note.
- The longest round trip is under 150 km.
- Trains terminating at Aylesbury Vale Parkway take around twenty minutes to go from Aylesbury to Aylesbury Vale Parkway and back to Aylesbury, which is more than enough time to charge a battery-electric train.
- It is mainly single-track between Aylesbury Vale Parkway and Aylesbury stations.
- Princes Risborough shuttles seem to wait be at Aylesbury station for about ten minutes, which is more than enough time to charge a battery-electric train, for the short route.
- Direct Marylebone services via Amersham 80 miles (appear to be at Aylesbury long enough to charge a battery-electric train.
It looks to me that if Aylesbury and Aylesbury Vale Parkway stations and the track between the two stations were to be electrified, that a battery-electric train with a range in excess of 87 miles (140 km.) can run all services to Aylesbury and Aylesbury Vale Parkway stations.
Is there a battery-electric train with a range of say 150 km?
This page on the Hitachi Rail website is called Battery Commuter Trains.
If you download the fact sheet, it says that their four-car battery-electric train has a range of 150 km.
I suspect that other manufacturers can also produce a four-car battery-electric train has a range of 150 km, that would suit Chiltern’s needs.
Electrification At Aylesbury
I estimate that only about four miles of single-track electrification will be needed at Aylesbury.
The cost of this can surely be bundled in with the cost of the new trains.
Conclusion
It looks to me, that with a few miles of electrification at Aylesbury, Hitachi can deliver trains, that will electrify services to both Aylesbury stations.
Derby Station – 15th December 2023
I took these pictures of Derby station, when I changed trains.
It’s the first time, that I’ve been in the station since it has been extended.
This Google Map shows the current station layout.
Note.
- There are now seven platforms.
- Platforms are numbered from the West.
- There is a bridge with lifts giving access to all platforms from both sides of the tracks.
Although, the station will be electrified, there is no sign of any pre-electrification works.
Huddersfield Station – 15th December 2023
I took these pictures at Huddersfield station today.
Note.
- The station is a Grade I Listed building.
- The station will be fully-electrified under the TransPennine Upgrade.
- St. George’s Square in front of the station is pedestrianised.
- There is a pub in each wing of the station.
This OpenRailwayMap shows the tracks between Huddersfield and the next station to the East; Deighton.
Note.
Huddersfield station is in the South-West corner of the map, where the tracks lead to Manchester.
Deighton station is in the North-East corner of the map, where the tracks lead to Leeds.
The tracks between the two stations will be electrified as part of the TransPennine Upgrade.
This second OpenRailwayMap shows the layout of platforms and tracks in Huddersfield station.
Currently, there are the following platforms.
- Platforms 1, 4 and 8 are through platforms.
- Platform 2 is a bay platform at the Manchester end of the station is used by trains on the Penistone Line to Sheffield.
- Platform 5 and 6 are two bay platforms at the Leeds end of the station, that are used by services to and from Bradford Interchange.
The Wikipedia entry for Huddersfield station says these changes will be made under the TransPennine Upgrade.
Work is underway on Network Rail’s Transpennine Route Upgrade project, which will see electrification of the Huddersfield Line, allowing many of the services through the station to switch to newer, faster electric rolling stock. As part of this project the signal box on platform 4 which was decommissioned previously will be removed, its control area already passed to the York Rail Operating Centre as a part of the Huddersfield Re-signalling project. To match the quadrupling of the line north of Huddersfield, the project will in effect split the existing island platform, extending the existing bay platforms 5 and 6 to form two new through platforms covered by a new roof, and add a new footbridge at the Leeds end. The process will also include relocating the 1880s island platform tea room, and rotating it through 180 degrees.
It looks like the functionality of the station for passengers, staff and operators will be upgraded to the level of style of the station.
Performing The Upgrade
I learned today, that during some parts of the upgrade work, Deighton station will be used as a temporary station for Huddersfield.
Three New Battery-Only Revolution Very Light Rail Vehicles
This title of this post, is the same as that as this press release from Eversholt Rail Group.
These are the three bullet points.
- Eversholt Rail funding three brand-new Revolution Very Light Rail vehicles for passenger trials and ongoing operation.
- Manufactured in the UK by Transport Design International.
- Battery-only propulsion, providing zero-emissions operation.
These three paragraphs fill out the story.
Innovative new lightweight passenger trains that will help decarbonise Britain’s railways are to be trialled after a new deal was announced this week.
The new Revolution Very Light Rail vehicles will run entirely on battery power and could be carrying passengers within three years. A new system of lineside fast charging will mean the whole operation has zero emissions.
Some of Britain’s major rail operators are already showing interest in the RVLR vehicles as they seek to fulfil promises to make rail ‘cleaner’.
This is also said about looking for routes, to trial the new vehicles.
Eversholt Rail and TDI are working with key stakeholders across the UK rail industry to agree routes and services where operators can run passenger-carrying trials using these new vehicles. These trials will generate actual passenger demand data to support business cases for long-term deployment of RVLR vehicles as well as providing further passenger and operator feedback on their design and capabilities.
I have some thoughts and questions.
What Is The Top Speed?
A lot of questions like this are answered by this article on Rail Engineer, which is entitled Very Light Rail – A Revolution.
These can be ascertained from this comprehensive article.
- Top Speed – 65 mph
- Seats – 56
- Wheelchair space
- PRM TSI accessibility compatible
- Tare Weight – 24.8 tonnes
- USB Charging
For comparison these figures relate to a PRM-compliant Class 153 diesel train.
- Top Speed – 75 mph
- Seats – 59
- Tare Weight – 41.2 tonnes
This picture shows one of the Class 153 trains at Matlock Bath station.
There are still around thirty in service in the UK.
Can Two Revolution VLRs Run As A Two-Car Train?
From the pictures on the web, the trains have buffers and space for a coupler, so until someone says they must always run as single units, I’ll assume they can at least run as a pair.
Can A Revolution VLR Recharge Its Batteries Using Conventional 25 KVAC Overhead Electrification?
One route, that is a possibility for running using Revolution VLR must surely be the Greenford Branch, which connects to the electrified Great Western Main Line at West Ealing station.
In this and at several other places on the network, it could be easier to charge the trains using the existing overhead electrification or an extension of it.
Another possibility; the Marston Vale Line is also electrified at both Bedford and Bletchley.
In New Mobile Rail Charging Facility For Long Marston, I talked about how Siemens are developing a mobile charger, which initially will be deployed at Long Marston.
It could be very useful for efficient operation, if the batteries on a Revolution VLR could be charged in a number of places, which included conventional electrification.
If charging only happened, whilst trains were stationary, a lightweight pantograph and appropriate electrical gubbins might be sufficient.
Can A Revolution VLR Replace A Class 153 Train?
I suspect on some routes this will be possible, but on others, the speed or hill-climbing requirements might be too stiff for the lightweight train.
But, if I was designing a train like the Revolution VLR, I’d make sure it fitted as many markets as possible.
The picture was taken at Matlock Bath station on the Derwent Valley Line, which is a single track with a fifty mph limit and an uphill climb. I suspect that the Revolution VLR would be designed to handle the uphill part of the route, but would the train be able to handle the speed of the Midland Main Line to Derby.
The Revolution VLR would probably attract more passengers, so it might be necessary to double up the service by running a pair.
Can A Pair Of Revolution VLRs Replace A Class 150 Train?
I don’t see why not!
Could The West London Orbital Use Revolution VLRs?
This might be a proposed route that could use Revolution VLRs.
The two routes would be.
- West Hampstead and Hounslow.
- Hendon and Kew Bridge.
Both services would use the Dudding Hill Line and serve Neasden, Harlesden, Old Oak Common and Acton, with a frequency of four trains per hour (tph).
Although this service could be run using conventional multiple units, it might be more affordable to use Revolution VLRs charged on sections of line that are already electrified.
Could the Greenford Branch Use Revolution VLRs?
The Greenford Branch would be a classic application and trains could be charged by fitting a charger in the bay platform at West Ealing station.
In An Automated Shuttle Train On The Greenford Branch Line, I did a rough calculation to see if an automated shuttle could achieve four tph.
Four tph might be too ambitious, but automatic trains shuttling along a branch line might be an affordable way to provide zero-carbon trains with an adequate capacity.
- The driver would drive the train using the sort of remote control used for drones.
- The driver would sit in a convenient place on the train, with CCTV to help them see everything.
- When the train was ready to leave, the driver would push a button to tell the train to move to the next station.
- On arrival at the next station, the doors will open.
- The process would repeat along the line.
If this method of operation sounds vaguely familiar, the Victoria Line has used it since 1067.
Although the Victoria Line drivers always sit in the front.
But on a line with no other trains running at the same time, all they need is a good view of the doors.
Branch lines that could be run in this way could include.
Bodmin Parkway and Bodmin General
Brockenhurst and Lymington Pier
Grove Park and Bromley North
Lancaster and Morecambe
Liskeard and Looe
Lostwithiel and Powey
Maidenhead and Marlow
March and Wisbech
Par and Newquay
Plymouth and Gunnislake
Romford and Upminster
Sittingbourne and Sheerness-on-Sea
Slough and Windsor Central
Southall and Brentford
St. Erth and St. Ives
Truro and Falmouth Docks
Twyford and Henley-on-Thames
Watford Junction and St. Albans Abbey
West Ealing and Greenford
Wickford and Southminster
Wymondham and Dereham
Crafty Electrification On The Rhymney Line
I was puzzled on Wednesday, when I took the Class 231 train to Caerphilly on the Rhymney Line, when I saw no signs of electrification.
These are pictures I took at Caerphilly station.
These two OpenRailwayMaps show the tracks through Caerphilly.
Note.
- The map on the left shows infrastructure, with the Rhymney Line shown in yellow.
- Caerphilly station is in the top third of the map.
- The white section of the Rhymney Line is the Caerphilly tunnel.
- The map on the right shows electrification, with the sections of the Rhymney Line that will be electrified are shown in red.
- Black sections will not be electrified.
- North of Caerphilly, the Rhymney Line is electrified, but through the station and the Caerphilly tunnel, there will be no electrification.
Trains will use battery power, where there is no electrification.
This article on Modern Railways gives more information.
This OpenRailwayMap shows the electrification around Cardiff Central and Queen Street stations.
Note.
- Electrified lines are shown in red.
- Unelectrified lines are shown in black.
- The four-platform Cardiff Queen Street station is marked by the blue arrow in the North-East corner of the map.
- There appears to be no plans for electrification in Cardiff Queen Street station.
- The electrified line across the map is the South Wales Main Line.
- The nine-platform Cardiff Central station sits on the South Wales Main Line.
- The main line platforms at Cardiff Central station are electrified, but it appears that Platforms 6.7 and 8. that will serve the South Wales Metro, will not be electrified.
- The line going to the South-East is the branch to Cardiff Bay station.
- The Southern part of this branch appears to be planned to be electrified. so that it can charge the tram-trains before they return North.
This article on Modern Railways says this about catenary-free sections (CFS) in the electrification of the South Wales Metro.
Catenary-free sections are concentrated on areas where it is disproportionately expensive to erect overhead wires. These include the area around Cardiff Queen Street station and the adjacent junction, which has complicated switches and crossings. North of Queen Street, the Cathays area adjacent to Cardiff University and the hospital would present a significant electromagnetic compatibility challenge, so a CFS avoids this complication. Other catenary-free areas will include Pontypridd, where the station features listed canopies and the track is curved, and around the new depot at Taff’s Well, where there will be a significant number of new switches and crossings as well as challenges around highway bridges.
I am in touch with two major electrification companies and I am sure we’ll be seeing a lot more crafty electrification and the use of battery-electric trains.
High Speed Two To Holyhead
Rishi Sunak has just announced that the North Wales Main Line will be electrified, along with the cancellation of further phases of High Speed Two.
I have written about this topic before in Could High Speed Two Serve Holyhead?.
In that post, I started with this question and answer.
Why?
It could be a way to create a zero- or low-carbon route between the islands of Great Britain and Ireland.
In Could High Speed Two Finish At Lichfield?, I discussed, what might happen if the Birmingham to Manchester leg of High Speed Two were to be scrapped.
This was my main conclusion.
I strongly believe that an upgraded Trent Valley Line linked to a shortened High Speed Two at Lichfield could improve journey times between London, Birmingham and the North.
As the current Holyhead services will pass this junction between the Trent Valley Line and High Speed Two, there is no reason, why they couldn’t take High Speed Two to and from London, if the service was run by High Speed Two Classic-Compatible Trains.
These are further thoughts.
Timings
These would be the times in hours:minutes.
- Bangor – 2:42
- Chester – 1:28
- Holyhead – 3:10
- Llandudno Junction – 2:24
Currently, Holyhead is three hours and forty-five minutes.
Would the Electrification Be Full Or Partial Between Crewe And Holyhead?
This question will be increasingly asked about electrification.
Consider.
- CAF, Hitachi, Siemens and Stadler are all developing battery-electric technology for trains.
- The UK’s first battery-electric train service goes into service tomorrow between Liverpool and Headbolt Lane station.
- Freight locomotives are increasingly being ordered with both electric and diesel power.
- Some of the castles, countryside and other monuments wouldn’t be enhanced, with lots of overhead electrification.
I think it is likely, that electrification will increasingly have gaps for visual, technical or heritage reasons.
Electrification of the North Wales Coast Line with other small improvements could probably reduce the journey time between London and Holyhead to around three hours.
Would There Be Enough Paths On The Trent Valley Line And High Speed Two?
This graphic shows High Speed Two services after Phase 2b is completed.
Note.
- Services shown in blue are run by High Speed Two Full Size trains.
- Services shown in yellow are run by High Speed Two Classic-Compatible trains.
- There are a total of 23 train paths of which eleven would need to go along the Trent Valley Line.
- The three London-Manchester services and the two Birmingham-Manchester services would have to be run by High Speed Two Classic-Compatible trains.
- The second Liverpool train is only a single train, but it could be a pair, that split at Crewe, with one train going to Liverpool and the other to Chester and North Wales.
- All the Avanti West Coast services, currently using the Trent Valley Line would probably be replaced by High Speed Two services.
There would have to be a bit of reorganising, but I suspect an hourly path could be found for a train between London and Holyhead.
A Fast Green Route To The Emerald Isle
Electrification of the North Wales Coast Line with other small improvements could probably reduce the journey time between London and Holyhead to around three hours.
This service could be paired with a fast zero-carbon ferry to the island of Ireland?
Conclusion
I am fairly sure that an HS2 service to Holyhead could be run, once the North Wales Coast Line is electrified.

Cunning Electrification On The North London Line
I took a trip on the North London Line from Highbury & Islington station to Richmond station.
I took various pictures on the way.
25 KVAC Overhead Electrification
East of Acton Central station, typical 25 KVAC overhead electrification is used.
It may need to be beefed up, if more large electric locomotives haul freight trains along the North London Line.
Gunnersbury Station
Gunnersbury station is a two-platform station with London Underground four-rail electrification.
It can be used by London Underground S-Stock and London Overground Class 378 trains.
It must help that both trains were built by Bombardier in Derby.
Kew Gardens Station
Kew Gardens station is a two-platform station with London Underground four-rail electrification.
As with Gunnersbury station, both types of train can use both platforms.
Richmond Station
Richmond station is both a through and terminal station.
Note.
- Platforms 1 and 2 are through platforms for South Western main line services.
- Platforms 3 to 7 are for terminating London Underground and Overground services.
- Platforms 1 to 3 have traditional third-rail electrification.
- Platforms 4 to 7 have London Underground four-rail electrification.
- If needed, it may be possible to add another platform between platforms 3 and 4.
It looks like a lot of flexibility has been built in.
I have a few general thoughts.
Getting The Voltages Right
London Underground’s system used to use 630 VDC for its four-rail system, whereas Network Rail’s system uses 750 VDC.
I wouldn’t be surprised to find out that both trains use quality power electronics that can work on a range of voltages. This would enable London Underground to up their voltage to the same 750 VDC as used by Network Rail.
In Chiltern Sets Out New Fleet Ambitions, I talked about how Chiltern Railways could use London Underground’s four-rail electrification between Harrow-on-the-Hill and Amersham stations to charge the batteries.
As an electrical engineer, I don’t think this is outrageous.
Liverpool Lime Street And Newcastle By Battery-Electric Class 802 Train
After my visit to Morley station, which I wrote about in Morley Station – 17th August 2023, in this post, I look at how a battery-electric Class 802 train might run between Liverpool Lime Street And Newcastle stations.
These are the various sections of the route.
- Liverpool Lime Street and Manchester Victoria – 31.6 miles – 36 minutes – Electrified
- Manchester Victoria and Huddersfield – 25.7 miles – 30 minutes – Not Electrified
- Huddersfield and Dewsbury – 8 miles – 7 minutes – Currently Being Electrified
- Dewsbury and Leeds – 9.1 miles – 14 minutes – Not Electrified
- Leeds and York – 25.8 miles – 30 minutes – Currently Being Electrified
- York and Newcastle – 80.2 miles – 58 minutes – Electrified
Note.
- Liverpool Lime Street and Manchester Victoria, Leeds and York and York and Newcastle are all long enough to fully charge a battery-electric train.
- There is electrification of both ends of the route.
- Manchester Victoria and York is a distance of 68.6 miles.
- The total route length is a distance of 180.4 miles.
In the August 2023 Edition of Modern Railways, there is an article, which is entitled GWR Seeks Opportunities To Grow.
This is the sub-heading.
Managing Director Mark Hopwood tells Philip Sherratt there is plenty of potential to increase rail’s economic contribution.
This is a paragraph.
Meanwhile, GWR had announced plans with Eversholt Rail to trial the replacement of a diesel generator unit with batteries on a Class 802 IET. However, Mr. Hopwood says this would not be useful for GWR and so the trial is not proceeding; instead, a TransPennine Express Class 802 will be the subject of a battery trial.
Could the trial be conducted on TransPennine Express’s Liverpool Lime Street And Newcastle route?
- The total route length is a distance of 180.4 miles.
- The two electrified sections at the ends of the route; Liverpool Lime Street and Manchester Victoria and York and Newcastle are both long enough to fully charge a battery-electric train.
- The central section between Manchester Victoria and York is not overly long at 68.6 miles.
- The route is convenient for Hitachi’s headquarters at Newton Aycliffe.
It looks like, the Liverpool Lime Street And Newcastle route would make an ideal test route for battery-electric Class 802 trains.
Manchester Piccadilly And Newcastle By Battery-Electric Class 802 Train
This is a very similar route to the Liverpool Lime Street And Newcastle route with a different Western terminal.
These are the various sections of the route.
- Manchester Piccadilly and Huddersfield – 25.5 miles – 42 minutes – Not Electrified
- Huddersfield and Dewsbury – 8 miles – 10 minutes – Currently Being Electrified
- Dewsbury and Leeds – 9.1 miles – 14 minutes – Not Electrified
- Leeds and York – 25.8 miles – 30 minutes – Currently Being Electrified
- York and Newcastle – 80.2 miles – 58 minutes – Electrified
Note.
- Turnround time at Manchester Piccadilly and York and Newcastle are all long enough to fully charge a battery-electric train.
- There is electrification of both ends of the route.
- Manchester Piccadilly and York is a distance of 68.4 miles.
- The total route length is a distance of 148.5 miles.
Like the Liverpool Lime Street And Newcastle route, I believe the Manchester Piccadilly And Newcastle route would make an ideal test route for battery-electric Class 802 trains.
