New Chiltern Railways Trains Set To Unlock 10,000 More Seats A Day
The title of this post is the same as that of this press release from Chiltern Railways.
This picture from Chiltern Railways shows the train at Marylebone.

These three paragraphs are from the press release and add more details.
Chiltern Railways today (Tuesday 14 October) showcased for the first time its newest (Mark 5A) trains, set to add 10,000 more seats for customers each weekday from December 2026.
The trains, to be introduced between London to West Midlands from early 2026, will enable Chiltern to deliver more capacity across each of its West Midlands, Aylesbury, and Oxford routes as part of the operator’s efforts to deliver better journeys for customers.
The newest fleet will consist of 13 modern trains set to transform customer journeys during 2026. The trains will replace Chiltern’s oldest carriages, which are nearly 50 years old, with state-of-the-art equivalents, and provide a significant improvement to the on-board experience.
Today, I also received an update from Modern Railways, which was entitled Chiltern Railways Mk 5As To Enter Traffic Early Next Year, and included this delivery schedule.
From December 2026 there will be ten Mk 5A sets in traffic each day, with one ‘hot spare’ and one undergoing maintenance. That leaves one extra set which, CR has suggested, could eventually be pressed into traffic.
I have a few thoughts.
How Do The Trains Compare Physically?
These are basic figures for the two different types of train sets.
- The current Mark 3 are five-car sets of 23 metres coaches, that weigh about 36 tonnes. The driving van trailer is 18.83 metres and 43.7 tonnes
- The future Mark 5A are four-car sets of 22.2 metres coaches, that weigh about 43 tonnes. The driving trailer is 22.37 metres and 43 tonnes.
Lengths and weights of various sets will be as follows.
- Mark 3 – five-car and driving van trailer – 133.83 metres and 223.7 tonnes.
- Mark 5A – four-car and driving trailer – 111.17 metres and 215 tonnes
- Mark 5A – five-car and driving trailer – 155.57 metres and 258 tonnes
Note.
- Chiltern Railways and TransPennine Express use the same Class 68 locomotives.
- The five-car Mark 3 and the four-car Mark 5A sets are quite similar in length and weight
- This could mean that both sets would perform similarly with the same locomotives on the same route.
- I wouldn’t be surprised that the new Platform 4 at Birmingham |Snow Hill station will be able to handle all configurations.
I almost feel that when CAF designed the Mark 5A sets for TransPennine Express, they also had Chiltern in mind as another possible sale.
How Many Trains Would Be Needed To Run Between London Marylebone And Birmingham?
Consider.
- Trains currently run half-hourly on the route between 06:00 to 23:30, which is up to 36 services per day.
- When Platform 4 is operational at Birmingham Snow Hill station, all services could probably stop at both Birmingham Moor Street and Birmingham Snow Hill stations.
- A round trip between London Marylebone and Birmingham Snow Hill stations currently takes about five hours.
I’m fairly certain that to run a half-hourly core service would need ten trains.
Could Chiltern Develop Another Network On The Other Side Of Birmingham?
Consider.
- Trains could run twice an hour from 06:00 to 23:30, which is up to 36 services per day.
- When Platform 4 is operational at Birmingham Snow Hill station, all services could probably stop at both Birmingham Moor Street and Birmingham Snow Hill stations.
- Chiltern Railways already run several services a day to Stourbridge Junction.
- Chiltern Railways have run services to Kidderminster station in the past.
- Wrexham & Shropshire used to run locomotive-hauled Mark 3 four-car sets with driving van trailers, as far as Wrexham via Shrewsbury.
It looks to me, that with the right rolling stock configurations, Chiltern’s network can be developed on the other side of Birmingham.
- Destinations could include Stourbridge Junction, Kidderminster, Shrewsbury, Wolverhampton, Chirk, Ruabon and Wrexham General.
- Some services would need longer trains.
Obviously services would only be run if they were viable.
Would It Help Growth In A Town Or Area, If It Had A Rail Connection To London And/Or The Nearest Major City?
I know Lincoln is on the other side of the country, but I asked Google AI if Lincoln’s rail link to London has brought growth to the city and received this answer.
Yes, Lincoln’s rail link to London has brought significant growth by improving tourism, business travel, and student mobility, and is expected to spur further economic benefits through faster journey times and increased services. The direct link has made Lincoln more accessible for visitors and is a key part of the city’s long-term strategy for economic growth and development.
That was fairly definite.
How would that apply to an extended Chiltern Main Line.
- Politicians are always saying growth is important.
- An extended Chiltern Main Line servicewould improve connections of a lot of places to London and Birmingham.
- Shrewsbury is the easiest connection for West Wales.
- Surely a rail connection to a major city, might tempt someone to open a branch or a new factory.
Would a rail service make people feel more included?
Midlands Rail Hub Looks To The Future With Preferred Alliance Partners
The title of this post, is the same as that of this press release from Network Rail.
The press release has a spectacular picture, which I’m showing here.
Note.
- High Speed Two’s Curzon Street station is on the left.
- Birmingham Moor Street station is in the centre.
- There appears to be parkland between the two stations.
- Is that the West Midlands Metro running across in front of Moor Street station?
This OpenRailwayMap shows the railway lines in the area.
Note.
- Electrified tracks are shown in red.
- Tracks without electrification are shown in black.
- West Midlands Metro tracks are shown in mauve.
- The red tracks going diagonally across the map are the four electrified tracks going into Birmingham New Street station.
- Birmingham New Street station is off the map to the West.
- To the North of the tracks going into Birmingham New Street station, there are the seven platforms of High Speed Two’s Curzon Street station.
- The four platforms without electrification are shown South of the tracks into Birmingham New Street station.
- Two platforms at Birmingham Moor Street station are through platforms, that pass under Birmingham City Centre to Birmingham Snow Hill station.
- The other two platforms at Birmingham Moor Street station are bay platforms.
- The West Midlands Metro appears to take a loop around the stations.
But when you get into the words of the press release, there are a lot of vegetables and very little meat.
- The Midlands Rail Hub could cost around £1.75bn if delivered in full.
- The government’s recent spending review committed to progress the next stage of Midlands Rail Hub.
- Alongside this, planning is underway to begin to deliver two smaller but significant upgrades to benefit passengers as quickly as possible.
- The Alliance partners will be VolkerRail, Laing O’Rourke, AtkinsRéalis, Siemens Mobility, and Network Rail.
These four paragraphs indicate the work, that could be done.
The biggest change will be connecting the Chiltern main line, which runs into Moor Street, with the Camp Hill lines which run towards the South West and East Midlands via two new chords in Bordesley, near Birmingham city centre.
The transformation of the network will include running more train services on key routes through Birmingham and significantly improving connections for the millions of people who use the railway every day.
Work will be prioritised to explore how smaller, but vital, pieces of work which will provide passengers and communities with quicker benefits, including new journey options and more trains can be delivered as soon as possible.
They include reopening platform 4 at Snow Hill station so additional Chiltern Railways services can run directly between Birmingham’s business district and London Marylebone, and redeveloping Kings Norton station and the lines through it so extra Cross City trains can be added and new Midlands Rail Hub-enabled services can call there.
Three projects are specifically mentioned.
- The new chords in Bordesley.
- The reopening of platform 4 at Snow Hill station.
- The redeveloping of Kings Norton station.
I shall now look at each in detail.
The New Chords At Bordesley
This OpenRailwayMap shows the tracks going into and around Birmingham Moor Street station.
Note.
- Electrified tracks are shown in red.
- Tracks without electrification are shown in black.
- West Midlands Metro tracks are shown in mauve.
- The red tracks going diagonally across the map are the four electrified tracks going into Birmingham New Street station.
- Birmingham New Street station is off the map to the West.
- To the North of the tracks going into Birmingham New Street station, there are the seven platforms of High Speed Two’s Curzon Street station.
- The black track running NW-SE is the Chiltern Main Line between London Marylebone and Birmingham Moor Street stations.
- Birmingham Moor Street station is indicated by the blue arrow in the North-West corner of the map.
- The black track running NE-SW is the Camp Hill Line, that allows services to cross Birmingham.
Two new chords will be built where the Chiltern Main and the Camp Hill Lines cross, to allow services on the Camp Hill Line to call at Birmingham Moor Street station.
Consider.
- The press release described these chords as the biggest change.
- The chords will probably not be fully used, until the new stations are built on the Camp Hill Line.
- There may be need for extra platforms at Birmingham Moor Street station to accommodate any new services.
For these reasons, I suspect that these chords could well be the project that is pushed back to a later date.
The Reopening Of Platform 4 At Snow Hill Station
This OpenRailwayMap shows the track layout at Birmingham Snow Hill station.
Note.
- The two lilac tracks are the West Midlands Metro.
- The two orange tracks are the two through tracks between Birmingham Moor Street and Stourbridge Junction stations.
- Platform 3 is the Southbound track to Birmingham Moor Street on the right.
- Platform 2 is the Northbound track to Stourbridge Junction on the left
- Platform 1 is a loop on left.
- Platforms 1, 2 and 3 are all bi-directional.
- The closed Platform 4 is on the right and is shown by the black track.
I would expect that this reopening could be fairly straightforward and may also have worthwhile benefits.
- Would an extra platform, allow all Chiltern services to serve both Birmingham Moor Street and Birmingham Show Hill stations?
- Chiltern would probably find it easy to extend services from Birmingham to the North-West of the city.
- In this century, services have run as far as Wrexham from Marylebone.
- If all Chiltern services terminated at Birmingham Show Hill station would this have operational and/or marketing advantages?
- If all Chiltern services terminated at Birmingham Show Hill station would this, make it easier for some passengers to get a train to London and the South?
- If all Chiltern services terminated at Birmingham Show Hill station would this release a platform at Birmingham Moor Street station for other services?
These are a few pictures of Birmingham Snow Hill station.
Platform 4 at Birmingham Snow Hill station could be a Build One Platform-Get One Free At Another Station situation!
The Redeveloping Of Kings Norton Station
This will probably be needed for running services on the Camp Hill Line, so why not get some of the work done early, so the rebuilding doesn’t effect existing services?
This OpenRailwayMap shows the Eastern end of Kings Norton station
Note.
- Electrified tracks are shown in red.
- Tracks without electrification are shown in black.
- The station has four platforms, but some are unused.
- Two platforms are on an island, with a single platform on either side.
This OpenRailwayMap shows the Western end of Kings Norton station.
The notes to the previous map apply.
These two paragraphs from the Wikipedia entry for Kings Norton station, describe the station.
With the development of both bus and tram services, the need for such a large facility reduced from the 1930s onwards. The result is that today although all four platforms remain in place, only the outer two are in passenger use, with the middle island platforms now derelict.
Refurbished as part of the Cross-City line in 1978, it retained some of its original features following refurbishment, unlike the other ‘cross city line’ stations. The original station building survived, leased out for commercial purposes, until it was demolished in February 2006 for safety reasons. An extension car park provides a Park and Ride facility.
Disabled-access doesn’t seem to be the best either.
These pictures show the station.
Note.
- As I guessed, there is no disabled-access.
- But there are Braille markings on the handrails down to the platforms.
- Two CrossCountry trains are seen going through the station.
- The local Class 730 trains, lights and information screens appeared to be new.
- Three platforms are electrified, but the fourth is not.
- The electrification structure could probably be used to electrify the fourth platform.
- Only the two outside platforms ; 1 and 4 are in use, with the central island platforms ; 2 and 3 left derelict.
- There is car parking and possibly space for more.
- The two active platforms are 150 metres long and the six-car Class 730 trainstrains appear to be 144 metres long.
- The Class 220 trains, that are run by CrossCountry Trains appear to be 93 metres long.
It was one of the scruffiest stations, that I’ve ever seen.
These are my thoughts on the station.
Handling The Camp Hill Line
Refurbishing Kings Norton Station
I don’t feel, that this will be the most horrendous of jobs, as it is very much a job, where all the rubbish and wild forest is removed and new platforms and a bridge are built.
CrossCountry’s Bournemouth And Manchester Piccadilly Service
Whilst I was at Basingstoke station yesterday one of CrossCountry‘s services between Bournemouth and Manchester Piccadilly came through, so I took these pictures.
It was a long formation of Class 220 trains.
Could This Service Be Replaced By Hitachi Regional Battery Trains?
This Hitachi infographic gives the specification of the Hitachi Regional Battery Train.
I feel that in most condition, the range on battery power can be up to 56 miles.
I can break the Bournemouth and Manchester Piccadilly route into a series of legs.
- Bournemouth and Basingstoke – 60 miles – 750 VDC third-rail electrification
- Basingstoke and Reading – 15.5 miles – No electrification
- Reading and Didcot North Junction – 18 miles – 25 KVAC overhead electrification
- Didcot North Junction and Oxford – 10 miles – No electrification
- Oxford and Banbury – 22 miles – No electrification
- Banbury and Leamington Spa – 20 miles – No electrification
- Leamington Spa and Coventry – 10 miles – No electrification
- Coventry and Manchester Piccadilly – 101 miles – 25 KVAC overhead electrification
Note.
- 63 % of the route is electrified.
- The short 15.5 mile gap in the electrification between Basingstoke and Reading should be an easy route for running on battery power.
- But the 62 mile gap between Didcot North Junction and Coventry might well be too far.
The train would also need to be able to work with both types of UK electrification.
If some way could be found to bridge the 62 mile gap reliably, Hitachi’s Regional Battery Trains could work CrossCountry’s service between Bournemouth and Manchester Piccadilly.
Bridging The Gap
These methods could possibly be used to bridge the gap.
A Larger Battery On The Train
If you look at images of MTU’s Hybrid PowerPack, they appear to show a basic engine module with extra battery modules connected to it.
Will Hitachi and their battery-partner; Hyperdrive Innovation use a similar approach, where extra batteries can be plugged in as required?
This modular approach must offer advantages.
- Battery size can be tailored to routes.
- Batteries can be changed quickly.
The train’s software would know what batteries were fitted and could manage them efficiently.
I wouldn’t be surprised to see Hitachi’s Regional Battery Train able to handle a gap only six miles longer than the specification.
Battery And Train Development
As Hitachi’s Regional Battery Train develops, the following should happen.
- Useable battery capacity will increase.
- The train will use less electricity.
- Actions like regenerative braking will improve and recover more electricity.
- Driving and train operating strategies will improve.
These and other factors will improve the range of the train on batteries.
A Charging Station At Banbury Station
If some form of Fast Charge system were to be installed at Banbury station, this would enable a train stopping at Banbury to take on enough power to reliably reach Oxford or Coventry depending, on their final destination.
This method may add a few minutes to the trip, but it should work well.
Electrification Of A Section Of The Chiltern Main Line
This could be an elegant solution.
I have just flown my helicopter between Bicester North and Warwick Parkway stations and these are my observations.
- The Chiltern Main Line appears to be fairly straight and has received a top class Network Rail makeover in the last couple of decades.
- There are a couple of tunnels, but most of the bridges are new.
- Network Rail have done a lot of work on this route to create a hundred mph main line.
- It might be possible to increase the operating speed, by a few mph.
- The signalling also appears modern.
My untrained eye, says that it won’t be too challenging to electrify between say Bicester North station or Aynho Junction in the South and Leamington Spa or Warwick Parkway stations in the North. I would think, that the degree of difficulty would be about the same, as the recently electrified section of the Midland Main Line between Bedford and Corby stations.
The thirty-eight miles of electrification between Bicester North and Warwick Parkway stations would mean.
- The electrification is only eight-and-a-half miles longer than Bedford and Corby.
- There could be journey time savings.
- As all trains stop at two stations out of Banbury, Leamington Spa, Warwick and Warwick Parkway, all pantograph actions could be performed in stations, if that was thought to be preferable.
- Trains would be able to leave the electrification with full batteries.
- The electrification may enable some freight trains to be hauled between Didcot and Coventry or Birmingham using battery electric locomotives.
Distances of relevance from the ends of the electrification include.
- London Marylebone and Bicester North stations – 55 miles
- London Marylebone and Aynho junction – 64 miles
- Didcot North and Aynho junctions – 28 miles
- Leamington Spa and Coventry stations – 10 miles
- Leamington Spa and Birmingham Snow Hill stations – 23 miles
- Leamington Spa and Stratford-upon-Avon stations – 15 miles
- Warwick Parkway and Birmingham New Street stations – 20 miles
- Warwick Parkway and Birmingham Snow Hill stations – 20 miles
- Warwick Parkway and Kidderminster – 40 miles
- Warwick Parkway and Stratford-upon-Avon stations – 12 miles
These figures mean that the following services would be possible using Hitachi’s Regional Battery Train.
- Chiltern Railways – London Marylebone and Birmingham Moor Street
- Chiltern Railways – London Marylebone and Birmingham Snow Hill
- Chiltern Railways – London Marylebone and Kidderminster
- Chiltern Railways – London Marylebone and Stratford-upon-Avon
- CrossCountry – Bournemouth and Manchester Piccadilly
- CrossCountry – Southampton Central and Newcastle
- Midlands Connect – Oxford and Birmingham More Street – See Birmingham Airport Connectivity.
Other services like Leicester and Oxford via Coventry may also be possible.
As I see it, the great advantage of this electrification on the Chiltern Main Line is that is decarbonises two routes with the same thirty-eight miles of electrification.
Conclusion
CrossCountry’s Bournemouth And Manchester Piccadilly service could be run very efficiently with Hitachi’s proposed Regional Battery Train.
My preferred method to cross the electrification gap between Didcot North junction and Coventry station would be to electrify a section of the Chiltern Main Line.
- The electrification would be less than forty miles.
- I doubt it would be a challenging project.
- It would also allow Hitachi’s proposed trains to work Chiltern Main Line routes between London Marylebone and Birmingham.
I am fairly certain, that all passenger services through Banbury would be fully electric.
Midland Metro Arrives In New Street
These pictures show the Midland Metro and its new extension to Birmingham
New Street station.
I’d taken a train to Birmingham Snow Hill station and my only criticism, is that the signage at Snow Hill didn’t indicate how to get to the new tram stop.
