Could Electric Trains Run Between St. Pancras International and Sheffield Stations With No More Electrification?
A reader suggested, that I look at this, so here goes!
- A couple of weeks ago, I took a Class 222 diesel train back from Sheffield to St. Pancras International and it seemed a few minutes quicker.
- Looking at the timetable today, at least one service on the route is now just under two hours and some others are just over.
So the new Class 810 trains may not be fully in service yet, but the trains have already had an effect on the timetable.
How Far North Is The Midland Main Line Being Electrified?
I asked Google AI this question and received this answer.
As of early 2026, the Midland Main Line (MML) is electrified as far north as Wigston, just south of Leicester.
- Northern Limit: The section from Kettering up to Wigston South Junction was energised in July 2024, representing the current northern limit of 25kV overhead line equipment (OLE).
- Pause in Further Electrification: Following a UK government spending review, the further, planned northward extension of electrification to Leicester, Derby, Nottingham, and Sheffield was indefinitely paused in July 2025.
- Current Operations: While electrification has stopped at Wigston, the line is served by new bi-mode (electro-diesel) trains, allowing for electric running from London St Pancras to Wigston before switching to diesel power.
- Previous Work: The line is also fully electrified from London St Pancras to Bedford, including the route to Corby.
Note.
- South Wigston Junction and Sheffield are 69.4 miles apart.
- The Hitachi trains can raise and lower pantographs on the move.
Distances without wires from London St. Pancras International to various destinations are as follows.
- Sheffield – 69.4 miles
- Leicester – 3.7 miles
- Derby – 36.4 miles
- Nottingham – 31.1 miles
As trains will have to go out and back to these destinations distances travelled will be doubled.
- Sheffield – 138.8 miles
- Leicester – 7.4 miles
- Derby – 72.8 miles
- Nottingham – 62.2 miles
It looks to me, that if the new Class 810 trains, can travel 138.8 miles on batteries and diesel engines as a tri-mode train, then the Midland Main Line is electrified.
Could The Sheffield Services Turn Round At Doncaster And Charge Their Batteries There?
Note.
- South Wigston Junction and Doncaster are 79.5 miles apart.
- Doncaster is a fully-electrified station.
- Sheffield and Doncaster would get two extra connecting trains per hour.
- The two services could also call at Meadowhall and/or Rotherham Central.
The Class 810 trains could charge their batteries, whilst passengers to and from Doncaster left and entered the trains.
Could A Simple Cross-Platform Change Be Arranged Between East Coast And Midland Main Line Services?
Doncaster station has two long island platforms, one of which is generally used for Northbound services and one for Southbound services.
Note.
- All electrified tracks are shown in red.
- The two wide island platforms, with Northbound on the West side and Southbound on the East side.
- Each island platform has an electrified platform face on both sides.
- The four platforms faces on the island platforms can hold pairs of five-car Hitachi trains.
- There are two through tracks or avoiding lines between the two island platforms for trains that aren’t stopping.
- There are bay platforms at the ends of the station for local trains.
- The station is fully step-free with a wide pedestrian underpass.
I know the station well and it looks to me, that East Midland Railway’s five-car services for St. Pancras could charge up in the Southern ends of the four faces of the island platforms and the two South-facing bay platforms.
I also believe that a pair of five-car Class 810 trains could be handled and charged, should it become necessary.
It looks to me, that the engineers updating the East Coast Main Line, know that they were caught out badly by High Speed Two, so the redesign for the next fifty or a hundred years will be completely future-proofed.
Doncaster and London could almost be considered to be twin main lines, with two pairs of high speed lines taking different routes, that serve different towns and cities.
How Many Travellers Go Between East Scotland And The North-East of England And The English Midlands?
It must be quite a few, as in the new East Coast Main Line timetable, more Scottish services stop at places like Doncaster and Newark.
But surely, if you could go between say Perth or Aberdeen and Derby or Nottingham in two battery-electric trains, with a relaxed change at Doncaster, you’d take it?
I certainly would!
East Coast And Midland Main Lines Compared
These are times between London and Doncaster.
- Current times between Doncaster and London are typically between 1 hour and 31-40 minutes going via the East Coast Main Line.
- I estimate times between Doncaster and London will be typically 2 hours and 22-27 minutes going via the Midland Main Line.
Note.
- Doncaster and London King’s Cross is 156 miles
- Doncaster and London St. Pancras International is 183.3 miles
- So the Midland Main Line route would appear to to be about 45 minutes slower.
- I suspect, that for passengers between between London and North of York, it will always be quicker to use an East Coast Main Line service.
These are times between London and Sheffield.
- Current times between Sheffield and London are typically between 2 hours and 4-9 minutes going via the Midland Main Line.
- I estimate times between Sheffield and London will be typically between 2 hours and 2 minutes going via the East Coast Main Line.
Note.
- Sheffield and London King’s Cross is via Retford.
- Sheffield and London King’s Cross is 162.1 miles
- Sheffield and London St. Pancras International is 183.3 miles
- Sheffield and Retford is 23.5 miles
- So the Midland Main Line route would appear to to be a few minutes slower.
I would feel that there is scope that under Great British Railways to optimise services between London and Doncaster and Sheffield.
The Master Cutler
The Master Cutler is a named train, that is described in this Wikipedia entry, that was introduced in 1947.
- Over its life it has run into both King’s Cross and St. Pancras.
- I can remember the train in the 1950s, running into King’s Cross.
- It has also been run to and from Leeds.
- It has been run as a Pullman service.
- There are reports of overcrowding in recent years.
It strikes me that the Master Cutler could do with a revamp.
- As St. Pancras can accept pairs of five-car Class 810 trains, ten-car trains could be run into King’s Cross or St. Pancras.
- An alternative would be to use a nine-car Hitachi Class 800/801 train.
- All trains would be battery electric.
- All trains would use the East Coast Main Line for a faster service.
- Services could terminate in the North at Leeds.
- The service could be run as a Pullman service.
- This article on Ian Visits, writes about East Coast Main Line trains using St. Pancras.
I would create a train service, that would attract passengers from all over the world.
Who knows?
If it was conceived in the right way, it might warrant a second service or similar service on other lines like these possibilities.
London and Blackpool via Crewe, Wigan and Preston.
- London and Aberystwyth via Birmingham and Shrewsbury.
- London and Bristol via Bath
- London and Fishguard via Cardiff and Swansea
- London and Holyhead via Birmingham and Chester
- London and Liverpool
- London and Manchester
- London and Newcastle via York and Durham
- London and Norwich via Colchester and Ipswich
- London and Plymouth via Exeter
Note.
- All routes could be run using electric or battery-electric trains.
- The Fishguard and Holyhead services would be zero-carbon routes to Ireland, connecting to appropriate zero-carbon ferries.
- Could services be arranged so that all parts of the country have at least one service in both directions every day?
- In the days of British Rail, London and Norwich had a very high-class service, that could serve a full English breakfast between Colchester and London, which certainly wasn’t like the regular joke.
Get the offering right and it could level-up the UK.
St. Pancras And Leicester Via Corby
This OpenRailwayMap shows the route between Kettering and Leicester via Corby.
Note.
- Kettering station is in the bottom right corner of the map.
- Kettering is on the Midland Main Line from St. Pancras.
- North of Kettering the route splits into two.
- The Midland Main Line goes North-West through Market Harborough to Wigston junction and Leicester.
- The Midland Main Line is electrified to Wigston junction.
- The Corby branch goes North-East to Corby, which is indicated by a blue arrow.
- The Corby branch is electrified to Corby.
On Saturday, I went to Leicester and because there were engineering works at Market Harborough, the train went via Corby.
Over The Welland Viaduct
After Corby, the train went over the Welland Viaduct and I took these pictures.
It is an impressive viaduct and is the longest viaduct across a valley in the United Kingdom.
I have some further thoughts.
Could The Corby Service Be Extended to Leicester?
Consider.
- Between Corby and Leicester is 40.8 miles of track without electrification.
- Trains could call at Oakham, Melton Mowbray and Syston stations.
- Oakham, Melton Mowbray and Syston stations, could be given an appropriate number of trains every day to Leicester, Corby, Kettering, Wellingborough, Bedford, Luton, Luton Airport Parkway and London St. Pancras International stations.
- No new infrastrructure would be needed.
- I suspect an hourly service would be sufficient.
I am fairly sure that a Class 810 train fitted with batteries could work the route.
Leicester, Oakham, Melton Mowbray And Syston Stations Would Get A Direct Connection To Luton Airport
Some travellers might find this very useful.
Leicester Station Would Have A Neat Passenger Drop-Off For Luton Airport
I wrote about this in Busiest UK Airports Raise Kiss-and-Fly Fees, Says RAC.
Every rail station needs a passenger drop-off as good and affordable as the one at Leicester station.
Could East Midlands Railway Run A St. Pancras And Leeds Service?
East Midlands Railway’s new Class 810 trains have been designed, so that a pair will fit into one platform at St. Pancras.
If we assume one platform at St. Pancras is used for the Corby and Luton Airport Express services, that leaves three platforms for pairs of Class 810 trains to run expresses to the East Midlands.
This could be as many as twelve pairs of five-car trains per hour.
Where wioll they all terminate in the North?
Leeds station must be the obvious new destination.
- Leeds has the largest population and is the largest commercial and finance centre in Yorkshire and the North-East.
- Leeds would have gained three trains per hour (tph) from London, two tph from Birmingham and four tph from the East Midlands Hub at Nottinham.
- Leeds is getting a brand new metro.
- Leeds is a fully-electrified station, so it could charge the trains before they return to Sheffield, Leicester, Wigston junction and St. Pancras.
- Leeds and Wigston junction is 107.8 miles, which should be within the range of a battery-electric Class 810 train. If it is too far, an extended stop could be taken at Sheffield to top up the batteries.
- Note that Stadler hold the Guinness World Record for the greatest distance covered on one charge at 139 miles. Hitachi Rail, who are partnered with JCB’s battery-maker in Sunderland, should be able to smash that.
The Rail Minister; Lord Peter Hendy went to Leeds University.
Which Route Would The Trains Take Between Sheffield And Leeds?
Consider.
- The fastest trains between Sheffield and Leeds, go via Meadowhall, Barnsley and Wakefield Kirkgate stations.
- Trains take about an hour.
- The current frequency is two tph.
- The distance is 41.1 miles with no electrification.
A frequency of two additional tph between St. Pancras and Leeds would give the following.
- A nice round four tph between Yorkshire’s two most important cities.
- Four fast tph between Meadowhall, Barnsley and Wakefield Kirkgate stations, and Leeds and Sheffield.
- Two direct trains between Meadowhall, Barnsley and Wakefield Kirkgate, and Chesterfield, Derby, Long Eaton, East Midlands Parkway, Loughborough, Leicester and St. Pancras.
It would be complimentary to any Leeds Metro.
Could East Midlands Railways Also Serve Huddersfield?
Consider.
- Huddersfield is 36.4 miles further than Sheffield on the Penistone Line, which is not electrified.
- Wigston junctionand Huddersfield station is 105.3 miles.
- Huddersfield is a Grade I Listed station with two pubs in the middle of the town.
- Huddersfield station is being fully-electrified in connection with the TransPennine Upgrade.
- All trains from Sheffield, that use the Penistone Line terminate in Platform 2 at Huddersfield station.
This OpenRailwayMap shows the position of Platform 2 in the station.
Note.
- The red-and-black dotted tracks are being electrified.
- The black tracks are not going to be electrified.
- Platform 2 is marked 2 in the top-right corner of the map.
- Platform 2 looks to be about 90 metres long.
- Five-car Class 810 trains are 120 metres long.
- From the map, it looks like the platform could be lengthened by the required thirty metres.
I suspect that some form of charger can be squeezed into the available space. After all, you don’t often get the chance to put charging into one of the most grand stations in Europe. Power supply would not be a problem, because of the electrification.
A frequency of twotph between St. Pancras and Huddersfield would give the following.
- Two fast tph between Meadowhall, and Barnsley, and Huddersfield and Sheffield.
- Two extra direct trains between Meadowhall and Barnsley, and Chesterfield, Derby, Long Eaton, East Midlands Parkway, Loughborough, Leicester and St. Pancras.
It would connect many stations to the TransPennine Route at Huddersfield station.
What Could The Sheffield and St. Pancras Look Like?
Consider that currently.
- There are two tph.
- Trains stop at Leicester, Loughborough (1tph), East Midlands Parkway (1tph), Long Eaton (1tph), Derby and Chesterfield.
- Trains are five- or seven-cars.
The simplest solution would probably be.
- A pair of five-car trains run all services.
- Trains split and join at Sheffield with one train going to Leeds and one going to Huddersfield.
I estimate that the Class 810 trains will offer about thirty more seats in every hour.
The Problem Of Electrifying Leicester Station
This post is my attempt to try and explain the problem of electrifying the Midland Main Line through Leicester station.
This Google map shows the Southern end of the station.
This OpenRailwayMap shows the station.
Note.
- There appear to be five tunnels under the station buildings and London Road.
- What is the tunnel going underneath the tracks used for?
Leicester station has a Grade II Listed frontage.
Note.
- It is an impressive Victorian station.
- The station building is on a bridge over the tracks.
- The station is also on one of the main roads through Leicester.
- The road layout is very complicated.
This 3D Google Map, shows an aerial view of the station.
Note.
- There four platforms, which are numbered 1-4 from the left.
- The expresses between London and Derby, Nottingham and Sheffield use the two middle tracks.
- Other main line and East-West services use the outside platforms.
- There is an avoiding line for freight services.
- 5. The step-free footbridge is clearly visible.
This second 3D Google Map, shows an enlargement of the frontage of the station.
These pictures show what is inside the building at the front of the station.
The building would appear to be a Grade II Listed taxi rank and free twenty-minute car park.
There are plans to increase the capacity of the station.
- A fifth platform will be added.
- Three miles of quadruple track will be be built South of the station.
- The Midland Main Line was also to be electrified.
Real Time Trains indicates that the distance between Leicester and Wigston North junction is 3.1 miles.
This OpenRailMap shows that section of track.
Note.
- Leiester station is at the top of the map.
- Wigston junction is the triangular junction at the bottom of the map.
- Wigston North Junction is indicated by the blue arrow.
- OpenRailwayMap only shows a 100 mph Northbound track and a 90 mph Southbound track on the route.
It looks to me, that four tracks between Leicester and Wigston North junction would mean that trains could expedite arrivals to and departures from Leicester to and from the South.
South From Wigston Junction
Consider.
- London St. Pancras and Kettering is a four-track railway as far as the Corby Branch.
- North of Luton the slowest maximum speed is 100 mph, with much of the line rated at 110 mph plus.
- Wigston North junction and Luton station is 65.8 miles.
- Current Class 222 diesel trains typically take 40 minutes.
- This is an average speed of 98.7 mph.
- An average speed of 110 mph between Wigston North junction and Luton station would take 36 minutes.
- An average speed of 125 mph between Wigston North junction and Luton station would take 31.6 minutes.
- An average speed of 130 mph between Wigston North junction and Luton station would take 30.4 minutes.
I believe with track improvements and digital signalling, there are time savings to be gained between St. Pancras and Leicester stations.
Ultimately, if the 140 mph design speed of the Class 810 trains under digital signalling could be maintained, this would do the following.
- Push the St. Pancras and Leicester times under an hour.
- Push the St. Pancras and Nottingham times under ninety minutes.
- Push the St. Pancras and Sheffield times under two hours.
Batteries would only be used on the three miles between Wigston North junction and Leicester station.
Could Bi-Mode Trains Be Used?
They could be used initially and to prove if the partial electrification works.
But each train has four diesel engines and sometimes they will be working in pairs through the stations between Leicester and Sheffield.
Passengers will take a dim view of being covered in lots of diesel smoke, when they have been promised clean, zero-carbon electric trains.
But the battery-electric trains will be much quieter and pollution-free.
This page on the Hitachi Rail web site is entitled Intercity Battery Trains.
New Infrastructure Needed
The only infrastructure needed will be that which will support the new trains.
The Class 810 trains will be maintained at Etches Park at Derby.
If they are battery-electric trains, there may be some strategically-placed chargers, which typically would be a short length of overhead wire.
Wigston Junction – 10th July 2025
It now appears that Wigston Junction, is as far North, as electrification will get on the Midland Main Line for some time.
This OpenRailwayMap shows the maximum speeds through the junction.
Note.
- Leicester station is to the North.
- London is to the South.
- Nuneaton is to the West.
- South Wigston station is indicated by a blue arrow.
- The Midland Main Line goes between the North and South points of the junction.
- Trains going North have a maximum speed of 100 mph.
- Trains going South have a maximum speed of 80 mph.
- Trains going along the North-West leg of the junction have a maximum speed of 40 mph.
- Trains going along the South-West leg of the junction have a maximum speed of 30 mph.
It would also appear that trains going North on the Midland Main Line can have a maximum speed of 100 mph or even 110 mph for most of the way between Market Harborough and just before Leicester, whilst going South is perhaps a couple of minutes slower.
This OpenRailwayMap shows the original plan for electrification through the junction.
Note.
- Red tracks are electrified.
- Black tracks are not electrified.
- Black/red dashed tracked were being electrified, but most are now paused.
- As before South Wigston station is indicated by a blue arrow.
Only the South point of the junction is electrified.
These pictures were taken from the train, as I passed Southwards from the North point of the junction to Market Harborough station.
Note.
- The first three pictures show the chord connecting to South Wigston station and on to Nuneaton.
- The next six pictures show the extra single track on the East side of the junction.
- There is a third track South of Wigston junction, that is about two miles long and electrified.
- All tracks South of Wigston junction are electrified.
It looks like a train could wait in the loop and be passed by a Northbound express.
Could the loop be used to charge trains in an emergency?
Conclusion
It would appear that Wigston junction could be a suitable place for the electrification to be paused.
All services to the North of Wigston junction would be on battery power, unless there is electrification.
