New Rail Service From Newcastle To Edinburgh To Stop At These Northumberland Stations
The title of this post, is the same as that of this article on the Chronicle Live.
Details of the service are as follows.
- It will be run by TransPennine Express.
- It starts in December 2021.
- It will run five times per day (tpd)
- It will call at Cramlington, Morpeth, Widdrington, Alnmouth, Berwick-upon-Tweed, Reston and Dunbar.
It is planned to run at least until May 2023.
These are my thoughts.
What Trains Will TransPennine Express Use?
The service will probably need a single train, if it was run by a dedicated fleet of trains, that just shuttled between Edinburgh and Newcastle. TransPennine could use either an electric Class 802 train or a diesel Class 185 train.
The diesel train might not be a good idea for operational reasons as TransPennine’s current services to Newcastle and Edinburgh use Class 802 trains.
But this service wouldn’t need a Class 802 train, as the route is fully electrified, so TransPennine might use a Class 800 train, if one were available from another company in the First Group.
TransPennine could also extend selected Manchester Airport and Newcastle services to Edinburgh, which might be the most efficient ways of using both trains and platforms in Newcastle.
This would give those using the intermediate stations between Edinburgh and Newcastle a service to and from Manchester Airport and the intervening stations, with a change at Newcastle, which would involve staying on the same train.
I’d organise the service as five tpd between Manchester Airport and Edinburgh with calls at Manchester Piccadilly, Manchester Oxford Road, Manchester Victoria, Huddersfield, Dewsbury, Leeds, York, Northallerton, Darlington, Durham, Chester-le-Street, Newcastle, Cramlington, Morpeth, Widdrington, Alnmouth, Berwick-upon-Tweed, Reston and Dunbar.
The big advantage of this, is that TransPennine could use the existing Class 802 trains, although they may need one more.
Reston Station
It looks like it will be a much needed service, that will get the new Reston station up and running.
I suspect that, passenger numbers at Reston station will determine the calling pattern after May 2023.
Will Other Services Continue?
TransPennine Express only has one service that stops between Newcastle and Edinburgh and that is the hourly service between Liverpool Lime Street and Edinburgh stations and that only stops at Morpeth.
I doubt this service will be changed, although after May 2023, it may make some extra stops depending on passenger numbers on the new service.
It should be noted that CrossCountry and LNER call irregularly at Alnmouth, Berwick-upon-Tweed and Dunbar.
As LNER are in rather a mess over their new timetable, I suspect that after May 2023, there could be a bit of a sort out of services.
How Will The New Service Fit With The Reopened Northumberland Line?
Initially the Northumberland Line will run as far as Ashington and won’t open until 2023 at the earliest.
But plans exist to extend the Northumberland Line to Morpeth.
The new service would fit well with an extended Northumberland Line service.
How Will The New Service Fit With East Coast Trains New London And Edinburgh Service?
East Coast Trains will be running a new Open Access service between London and Edinburgh from this autumn.
- It will have a frequency of 5 tpd.
- It will stop at Newcastle, Morpeth and Stevenage.
- It will offer one way fares of £25.
East Coast Trains are another First Group company.
As both services are five tpd in both directions, will the two services co-ordinate stops, so that passengers between say London and Reston can take advantage?
Going North, the stopping train could follow the East Coast Trains express and going South the stopping train would be a few minutes in front of the express.
This would also help with maximising capacity between Edinburgh and Newcastle on the busy East Coast Main Line.
Conclusion
This new stopping service between Edinburgh and Newcastle looks to be a simple solution to improve passenger services for intermediate stations between the two important cities.
Anxiety Over HS2 Eastern Leg Future
I did think about giving this post a title of Here We Go Again, as it yet another story about delaying or cancelling the Eastern Leg of High Speed Two.
But in the end I decided to use the title of the article in the September 2021 Edition of Modern Railways.
I wrote about this subject in Is The Eastern Leg Of High Speed Two Under Threat? in December 2020.
In that post, this was my major conclusion.
To achieve the required timings for High Speed Two, major improvements must be made to existing track on the East Coast Main Line and these improvements will mean that existing services will be competitive with High Speed Two on time.
It is backed up by the timings in the following table., which show the direct time by High Speed Two and my best estimate of time on an improved East Coast Main Line.
- Bradford – Will not served by High Speed Two – One hour and fifty-four minutes
- Cleethorpes – Will not served by High Speed Two – Two hours and fifty-one minutes
- Darlington – One hour and forty-nine minutes – One hour and forty-nine minutes
- Doncaster – Will not served by High Speed Two – One hour
- Edinburgh – Three hours and forty minutes via Western Leg – Three hours and thirty minutes.
- Grimsby – Will not served by High Speed Two – Two hours and thirty-six minutes
- Harrogate – Will not served by High Speed Two – One hour and fifty-two minutes
- Huddersfield – Will not served by High Speed Two – Two hours and eight minutes
- Hull – Will not served by High Speed Two – One hour and fifty minutes
- Leeds – One hour and twenty-one minutes – One hour and thirty minutes
- Lincoln – Will not served by High Speed Two – One hour and fifty-one minutes
- Middlesbrough – Will not served by High Speed Two – Two hours and twenty minutes
- Newcastle – Two hours and seventeen minutes – Two hours and sixteen minutes
- Nottingham – One hour and seven minutes – One hour and fifty minutes
- Scarborough – Will not served by High Speed Two – Two hours and fifty-seven minutes
- Sheffield – One hour and twenty-seven minutes – One hour and twenty-seven minutes
- Skipton – Will not served by High Speed Two – Two hours and seven minutes
- Sunderland – Will not served by High Speed Two – Two hours and thirty minutes
- York – One hour and twenty-four minutes – One hour and twenty-four minutes
Note.
- I have included all destinations served by Grand Central, Hull Trains and LNER.
- I have included Nottingham and Sheffield for completeness and in case whilst electrification is installed on the Midland Main Line, LNER run services to the two cities.
- I suspect LNER services to Bradford, Harrogate, Huddersfield and Skipton will split and join at Leeds.
There are a total of nineteen destination in this table.
- Twelve are not served by High Speed Two.
- Six are not more than fifteen minutes slower by the East Coast Main Line.
Only Nottingham is substantially quicker by High Speed Two.
In Is The Eastern Leg Of High Speed Two Under Threat?, I said that if Nottingham services ran at the sort of speed on the East Coast Main Line, that a time of one hour and twenty-one minutes between London St. Pancras and Nottingham could be possible. That would be just fourteen minutes slower than the time on High Speed Two with a change at East Midlands Hub.
Conclusion
I am getting more convinced that we don’t need the Eastern Leg of High Speed Two to East Midlands Hub and Leeds for a few years yet, as by uprating the East Coast and Midland Main Lines we can handle the traffic that we currently are generating with ease.
Middlesbrough To London LNER Trains To Run From 13 December
The title of this post, is the same as that of this article on the BBC.
The title is clear and these paragraphs give details of the train service.
The daily weekday service in each direction will also connect nearby Thornaby with London King’s Cross.
The services will depart Middlesbrough at 07:08 and Thornaby at 07:15, arriving at King’s Cross at 10:22.
Northbound from London will leave at 15:25, stopping at York, to Thornaby at 18:08 and Middlesbrough at 18:18.
This is obviously not a complete service.
- It will be impossible to use direct trains to spend a day on Teesside from London, as I have done many times over the years, usually with a change at Darlington station.
- It needs to run seven days a week.
But as the article says, more work needs to be done at Middlesbrough to turn the trains.
Currently, LNER run one train per two hours (1tp2h) to York, which alternates with a service to Lincoln at the same frequency.
LNER have said, that the Middlesbrough service will be an extension of the York service.
- As York trains can be nine-car trains, this could explain the need for works at Middlesbrough station.
- As York and Middlesbrough are 51 miles and an hour apart, it looks to me, that once Middlesbrough station has been updated, LNER can extend services to Middlesbrough according to passenger demand.
I suspect that eventually, the London and Middlesbrough service will have a similar frequency as the Harrogate and Lincoln services of five trains per day (tpd).
What Real Time Trains Says About The Service
Although it’s exactly four months before the service starts, it has already been entered into Real Time Trains.
The following information is given about the services.
- One seven-minute stop at York going South and a five-minute stop going North.
- Changeover between diesel and electric at Longlands junction, where the Teesside trains leave and join the East Coast Main Line.
- Services do not appear to pass through Northallerton station.
Train times are as given by the BBC.
Splitting And Joining At Newark
I think it would be possible to combine the Lincoln, Middlesbrough and York services into one service.
- A pair of five-car Azumas would run between Kings Cross and Newark North Gate, with stops at Stevenage, Peterborough and Grantham.
- They would split at Newark North Gate station.
- The front train would continue Northwards to Middlesbrough, with stops at Retford, Doncaster, York and Thornaby.
- The rear train would continue Eastwards to Lincoln, with a possible extension to Grimsby Town and Cleethorpes.
Returning South the trains would join at Newark North Gate.
Note.
- As TransPennine Express services to and from Middlesbrough, call at Northallerton, LNER services could do the same.
- As with splitting and joining at Newark, only a five-car train runs to and from Middlesbrough, this could be used before the new platform at Middlesbrough is constructed.
- if this service ran at a frequency of 1tp2h, there would be space in the timetable for a new 1tp2h service to perhaps Newcastle and Edinburgh.
There are a lot of possibilities.
Battery-Electric Trains Between London And Middlesbrough
Only the twenty miles between Northallerton and Middlesbrough on the route are without electrification.
Hitachi have announced the Hitachi Intercity Tri-Mode Battery Train, which is described in this Hitachi infographic.
I believe that a version of this train could be given sufficient battery range to be able to achieve a round trip to Middlesbrough station from the electrification of the East Coast Main Line, without any need for charging at Middlesbrough.
It could be one of the first InterCity services in the world, run by battery-electric trains.
A New Timetable For The East Coast
The title of this post, is the same as that of an article in the August 2021 Edition of Modern Railways.
The Modern Railways article describes in detail the thinking behind the proposed timetable for the East Coast Main Line, that will be introduced in May 2022.
The new titletable would appear to be a compromise and judging by the number of complaints that have appeared in the media, the compromise doesn’t suit everyone.
A lot of my programming was concerned with the allocation of resources in large projects and that expertise convinces me, that the East Coast Main Line doesn’t have enough capacity to accommodate all the services that passengers need and train companies want to run.
These are my thoughts.
High Speed Two
When High Speed Two is completed to Leeds, it will add the following services to Leeds.
- Three trains per hour (tph) between London Euston and Leeds in a time of one hour and twenty-one minutes.
- Two tph between Birmingham Curzon Street and Leeds in a time of forty-nine minutes.
- One tph between Bedford and Leeds, run by Midlands Connect, in a time of one hour and thirty-six minutes.
Leeds will benefit from these services from the South on the new High Speed Two.
But the High Speed Two network has been designed to need to run three tph between York and Newcastle, which will have to share with other East Coast Main Line services.
Both High Speed Two and the aspiration of providing more services on the East Coast Main Line mean that more capacity must be provided between York and Newcastle.
High Speed Two is not mentioned in the Modern Railways article.
I know the Eastern Leg of High Speed Two is many years away, but surely, it should have an influence on the design of East Coast Main Line services.
For instance, destinations like Bradford, Cleethorpes, Doncaster, Harrogate, Huddersfield, Hull, Lincoln, Middlesbrough, Peterborough, Redcar, Scarborough, Skegness and Sunderland are unlikely to be served by High Speed Two services, so how does that determine our thinking, when planning train services to these destinations.
Perhaps, there should be lists of secondary destinations, that should be served by the various operators.
London And Leeds In Two Hours
This is mentioned in the Modern Railways article as being an aspiration of Virgin Trains East Coast, when they ran the franchise.
In Thoughts On Digital Signalling On The East Coast Main Line, I did a few rough calculations and said this.
Consider.
-
- The fastest current trains between London Kings Cross and Leeds take between two hours and twelve minutes and two hours and fifteen minutes.
- I suspect that the extra tracks into Kings Cross, that are currently being built will save a few minutes.
- There must be some savings to be made between Doncaster and Leeds
- There must be some savings to be made between London Kings Cross and Woolmer Green.
- There could be a rearrangement of stops.
I think it is highly likely that in the future, there will be at least one train per hour (tph) between London Kings Cross and Leeds, that does the trip in two hours.
It is my view, that any new East Coast Main Line timetable should include services between London Kings Cross and Leeds in a few minutes under two hours.
London And Edinburgh In Four Hours
This must be another objective of the train companies, as it is competitive with the airlines.
But it is not a simple process as cutting stops to save time, often annoys the locals.
So achieving the objective of a four-hour trip between London and Edinburgh probably needs some major upgrades to the East Coast Main Line.
Some of the improvements needed are detailed in Northern Powerhouse Rail – Significant Upgrades Of The East Coast Main Line From Leeds To Newcastle (Via York And Darlington) And Restoration Of The Leamside Line.
Projects in the related article include.
- Phase 2 Of The East Coast Main Line Power Supply Upgrade
- York to Church Fenton Improvement Scheme
- Darlington Station Remodelling
- The North Throat Of York Station Including Skelton Bridge Junction
- Use Of The Leamside Line
- Full Digital ERTMS signalling.
It would appear there’s a lot of work to do, but all of it, will be needed for High Speed Two.
The Modern Railways article does point out, that the new Hitachi trains have superior acceleration to the InterCity 225 trains, that they have replaced. So that will help!
Although it is a worthwhile objective, I think it will be some years before London and Edinburgh times of under four hours are obtained on the East Coast Main Line.
Hitachi’s Intercity Tri-Mode Battery Train
These trains are described in this Hitachi infographic.
Within a couple of years these trains will start to be seen on the East Coast Main Line serving destinations like Cleethorpes, Grimsby, Harrogate, Huddersfield, Hull, Lincoln, Middlesbrough and Sunderland.
Although, it says batteries will replace one engine in the infographic, I believe the standard five-car train for the East Coast Main Line will have two battery packs and an emergency diesel engine. Before the end of the decade, they will be fully-decarbonised with three battery packs.
Splitting And Joining
Although the Hitachi trains can accomplish splitting and joining with ease, it is only mentioned once in the Modern Railways article and that is concerned with a service to Huddersfield, which will split and join at Leeds.
I can see this being used to make sure that each train running into Kings Cross is either a nine-car or a pair of five-car trains, as this would maximise capacity on the route.
Currently, trains to York and Lincoln share a path into Kings Cross, with trains alternating to each destination, so each destination gets one train per two hours (1tp2h).
It would surely be possible for a pair of trains to leave Kings Cross, that split at Newark, with one train going to York and the other to Lincoln.
- The Modern Railways article says that the Middlesbrough service will be an extension of the 1tp2h York service.
- This means Kings Cross and Middlesbrough would call at Stevenage, Peterborough, Grantham, Newark North Gate, Retford, Doncaster and York.
- So at some time in the future could the Middlesbrough and Lincoln services share a path, with a split and join at Newark?
If the Lincoln and Middlesbrough services were to be run at a frequency of 1tp2h, the intervening paths could be used for other destinations.
Theoretically, by using pairs of five-car trains and splitting and joining, four destinations can be given a service of 1tp2h to and from London, that all use the same path.
I think the following splits and joins would be feasible.
- Lincoln/Middlesbrough splitting and joining at Newark North Gate.
- Lincoln/Scarborough splitting and joining at Newark North Gate.
- Nottingham/Sheffield splitting and joining at Newark North Gate.
- Harrogate/Huddersfield splitting and joining at Leeds.
- Bradford/Skipton splitting and joining at Leeds.
- Hull/Leeds splitting and joining at Doncaster.
Note.
- The two Lincoln splits and joins at Newark North Gate could possibly be arranged, so that Middlesbrough got roughly 1tp2h and Scarborough got perhaps two trains per day (tpd).
- Hull would be a very useful destination, as it is a large station to the East of the East Coast Main Line.
- Nottingham and Sheffield could be useful destinations during any disruption on the Midland Main Line, perhaps due to installation of full electrification.
The permutations and combinations are endless.
All Fast Trains Must Have Similar Performance
East Coast Trains, Hull Trains, LNER and TransPennine Express all use trains with similar performance.
But other operators like Great Northern use slower trains on the East Coast Main Line.
As the Hitachi trains will be running at up to 140 mph under the control of full digital signalling, it strikes me that for safe, fast and efficient operation, the other operators will need faster trains, where they run on the fast lines of the East Coast Main Line.
Grand Central
Grand Central‘s fleet of Class 180 trains will need to be replaced to decarbonise the operator and will surely be replaced with more 140 mph trains to take advantage of the digitally-signalled East Coast Main Line.
As their routes are not fully-electrified, I suspect they’ll be using similar Hitachi battery-electric trains.
The Cambridge Effect
Cambridge is becoming one of the most important cities in the world, let alone England and the UK.
It is generating new businesses at a tremendous rate and it needs an expanded rail network to give access to housing and industrial premises in the surrounding cities and towns.
- Peterborough is in the same county and is developing alongside Cambridge.
- Bury St. Edmunds, Norwich and other towns are being drawn into Cambridge.
- East West Rail to Bedford, Milton Keynes and Oxford is coming.
Cambridge is well-connected to London, but needs better connections to the North and Midlands.
King’s Cross And King’s Lynn
Currently, this route is run by 110 mph Class 387 trains.
These trains are just not fast enough for Network Rail’s 140 mph digitally signalled railway between King’s Cross and Hitchin.
In Call For ETCS On King’s Lynn Route, I examine how 125 mph trains and full digital signalling could be used to run between King’s Cross and King’s Lynn via Cambridge.
This would allow the trains to use the fast lines into King’s Cross.
I also feel, that to maximise the use of paths into King’s Cross, that the King’s Lynn service could be paired with a new Norwich service. The two trains would split and join at Cambridge.
Liverpool Lime Street And Norwich
This service is currently run by Class 156 trains and needs decarbonising. It also runs on 125 mph lines between.
- Peterborough and Grantham
- Nottingham and Sheffield
It certainly needs a thorough redesign and modern rolling stock to replace the current rolling road blocks.
East West Rail will certainly increase Cambridge and Norwich services to two tph, so why not terminate this Liverpool service at Cambridge rather than Norwich?
- Cambridge station has a lot of space to add extra platforms.
- The service would not need to reverse at Ely.
- It would add much-needed capacity to the Cambridge and Peterborough route.
- The service could even terminate at the new Cambridge South station.
- There have been plans for some time to split this service at Nottingham.
As between Peterborough and Grantham is a fully-electrified four-track line, I suspect that a Cambridge and Nottingham service could be handled by a 110 mph battery-electric train based on a Class 350 or Class 379 train.
Similar battery-electric trains could probably handle the Northern section between Nottingham and Liverpool Lime Street.
Stansted Airport And Birmingham Via Cambridge
After the work to the North of Peterborough at Werrington, this service has a clear route away from the East Coast Main Line, so it can be ignored.
The service does need decarbonisation and I suspect that it could be run by a 110 mph battery-electric train based on a Class 350 or Class 379 train.
CrossCountry And TransPennine Express Services
CrossCountry and TransPennine Express also run services on the Northern section of the East Coast Main Line.
- CrossCountry – 1 tph – Leeds and Edinburgh via York, Darlington, Durham, Newcastle, Alnmouth, Berwick-upon-Tweed and Dunbar (1tp2h)
- CrossCountry – 1 tph – Sheffield and Newcastle via Doncaster, York, Darlington and Durham.
- TransPennine Express – 1 tph – Liverpool Lime Street and Scarborough via Leeds, Garforth and York
- TransPennine Express – 1 tph – Manchester Airport and Redcar via Leeds, York, Thirsk, Northallerton, Yarm, Thornaby, and Middlesbrough.
- TransPennine Express – 1 tph – Liverpool Lime Street and Edinburgh via Leeds, York, Darlington, Durham, Newcastle and Morpeth.
- TransPennine Express – 1 tph – Manchester Airport and Newcastle via Leeds, York, Northallerton, Darlington, Durham and Chester-le-Street (1t2h)
In addition LNER and East Coast Trains also run these services on the same section.
- LNER – 1 tp2h – London Kings Cross and York
- LNER – 1 tph – London Kings Cross and Edinburgh via York, Darlington, Newcastle, Berwick-upon-Tweed
- LNER – 1 tph – London Kings Cross and Edinburgh via York, Northallerton (1tp2h), Darlington, Durham, Newcastle and Alnmouth (1tp2h)
- East Coast Trains – 5 tpd – London Kings Cross and Edinburgh via Newcastle and Morpeth.
Aggregating the stops gives the following.
- York – 8.5 tph
- Darlington – 6 tph
- Durham – 5 tph
- Chester-le-Street – 0.5 tph
- Newcastle – 6 tph and 5 tpd
- Morpeth – 1 tph and 5 tpd
- Almouth – 1.5 tph
- Berwick-on-Tweed – 2 tph
- Dunbar – 0.5 tph
Note.
- 1 tp2h = 0.5 tph
- Scotland is building two new stations at Reston and East Linton.
- Northern run trains between Newcastle and Morpeth.
It does appear from comments in the Modern Railways article, that the various train companies and passenger groups can’t agree on who calls where to the North of York.
Perhaps the Fat Controller should step in.
Between Newcastle and Berwick-on-Tweed
With the reopening of the Northumberland Line between Newcastle and Ashington, there may be an opportunity to reorganise services between Newcastle and Berwick-on-Tweed.
- Morpeth could be served via the Northumberland Line.
- Britishvolt are building a large gigafactory for batteries at Blyth.
- It would probably be a good idea to remove slow diesel services from the East Coast Main Line.
- Reston station will need a train service.
- Morpeth and Newcastle are under twenty miles apart on the East Coast Main Line and the route via Ashington is perhaps only ten miles longer.
It looks to me that local services on the Northumberland Line and between Newcastle and Reston on the East Coast Main Line could be run by a 110 mph battery-electric train.
Conclusion
There would appear to be a lot of scope to create a very much improved timetable for the East Coast Main Line.
I do think though that the following actions must be taken.
- Ensure, that all the long-distance train companies have trains capable of running at 140 mph under the control of digital signalling.
- Develop a 110 mph battery-electric train to work the local routes, that run on the East Coast Main Line.
- Get agreement between passengers and train companies about stopping patterns to the North of York.
- Use splitting and joining creatively to squeeze more trains into the available paths.
LNER would also need to increase their fleet.
LNER To Serve Cleethorpes
Under the proposed new LNER timetable, which will start in May 2022, there will be a new train service between London Kings Cross and Cleethorpes.
According to this article on the Lincolnite, which is entitled Direct Cleethorpes To London Rail Link ‘Close’ To Getting Go Ahead, there will be one service per day.
It will leave Cleethorpes at 06:24 and Grimsby Town at 06:32 before arriving at King’s Cross at 09:25.
The return will leave King’s Cross at 16:10 and arrive in Grimsby Town at 19:05 and Cleethorpes at 19:20.
The August 2021 Edition of Modern Railways makes these points about the service.
- The larger Azuma fleet makes this extension possible.
- ,A more regular service would require additional trains.
- LNER is examining whether other intermediate stations east of Lincoln could be served.
I would have thought, that Market Rasen station could be a possibility for an intermediate stop.
I have a few thoughts.
Extra Services
This single service is ideal for though living in Lincolnshire, but it doesn’t suit those people, who perhaps need to go to the area from London for business or family reasons.
- Lincoln appears to get around five or six trains per day in each direction to and from King’s Cross.
- Services are roughly one train per two hours.
- I suspect the Lincoln service can be run by a single train, that shuttles between King’s Cross and Lincoln stations.
I believe, that Cleethorpes needs at least a pair of services to and from London, so that travellers can spend a day in North-East Lincolnshire.
- This would probably need more trains.
- Services would go via Lincoln and Lincoln may get extra services to London.
- Selected services could stop at intermediate stations, like Market Rasen.
There are surely possibilities for a integrated timetable between King’s Cross and Lincoln, Market Rasen, Grimsby Town and Cleethorpes.
Battery-Electric Operation
Consider.
- LNER’s Class 800 trains are prime candidates for conversion to Hitachi Intercity Tri-Mode Battery Trains, so they can run away from the overhead wires of the East Coast Main Line to places like Lincoln, by the use of battery power.
- These battery trains could charge using the electrification between King’s Cross and Newark North Gate stations.
- The distance between Lincoln Central station and the East Coast Main Line is 16.6 miles.
- In Plans To Introduce Battery Powered Trains In Scotland, I quote Hitachi, as saying they expect a sixty mile range for battery trains.
I am sure, that these trains would have sufficient range on battery to be able to work King’s Cross and Lincoln services without using diesel.
But could the Hitachi trains reach Cleethorpes with some well-positioned charging?
- The distance between Lincoln and Cleethorpes stations is 47.2 miles.
- In Solving The Electrification Conundrum, I describe Hitachi’s solution to running battery-electric trains, by using well-placed short lengths of 25 KVAC overhead electrification controlled by an intelligent power system.
With a range of sixty miles on batteries and charging at Lincoln and Cleethorpes stations, it would appear that battery electric operation of Class 800 trains between King’s Cross and Cleethorpes is a distinct possibility.
Lincoln Station
Lincoln station has three operational through platforms and I suspect all would need to be electrified, so that trains could be charged as they passed through.
These are distances from Lincoln station.
- Cleethorpes – 47.2 miles
- Doncaster – 36.9 miles
- Nottingham – 33.9 miles
- Peterborough – 56.9 miles
- Sheffield – 48.5 miles
It does appear that if Lincoln station were to be electrified, most services from the city could be run using battery-electric trains.
Cleethorpes Station
This picture shows Cleethorpes station with two TransPennine Express Class 185 trains in the station.
Note.
- The Class 185 trains are diesel, but could be replaced by Hitachi Class 802 trains, which could be converted to battery-electric operation.
- Cleethorpes and Doncaster are 52.1 miles apart, which could be in range of Hitachi’s battery-electric trains.
- It doesn’t look to be too challenging to electrify a couple of platforms to charge the battery-electric trains.
- Cleethorpes station could surely charge both the LNER and the TransPennine Express trains.
- The Cleethorpes and Barton-on-Humber service which is under fifty miles for a round trip could also be replaced with battery-electric trains.
Cleethorpes station could be totally served by battery-electric trains.
Battery-Electric Trains For Lincolnshire
At the present time, there is a surplus of good redundant electrical multiple units and the rolling stock leasing companies are looking for places where they can be used.
Porterbrook are already looking to convert their fleet of Class 350 trains to battery-electric operation and I am certain, that now that Hitachi and others have solved the charging problem, a lot more trains will be converted.
Most would appear to be four-car 100 mph trains, which will be very convenient and should fit most platforms.
Conclusion
Running battery-electric Class 800 trains to Lincoln, Grimsby Town and Cleethorpes could be the start of decarbonisation of Lincolnshire’s railways.
What would battery-electric trains do for the economy of Lincolnshire?
Should All High Speed Long Distance Services To Newcastle Extend To Edinburgh?
Look at this Google Map of Newcastle station.
Note.
- It is built on a curve.
- It is on a cramped site.
- Platforms are numbered from 1 at the top to 8 at the bottom.
- Platform 2 seems to be used for all express services going North.
- Platforms 3 and 4 seem to be used for all express services going South.
- Not all platforms would appear to be long enough for nine-car Class 80x trains.
I am certain, that any nation with a sophisticated railway system wouldn’t build a station on a curve with no avoiding lines like Newcastle these days.
Network Rail have a plan to sort out Darlington station and I’m sure they’d like to sort out Newcastle as well!
Current Long Distance Trains Through And To Newcastle
These include.
- CrossCountry – Plymouth and Edinburgh or Glasgow via Alnmouth, Berwick-upon-Tweed and Dunbar.
- CrossCountry – Southampton Central or Reading and Newcastle.
- LNER – King’s Cross and Edinburgh via Berwick-upon-Tweed
- LNER – King’s Cross and Edinburgh via Alnmouth
- TransPennine Express – Liverpool Lime Street and Edinburgh via Morpeth
- TransPennine Express – Manchester Airport and Newcastle.
Note.
- All have a frequency of one train per hour (tph)
- All trains call at Newcastle.
- Two tph terminate at Newcastle and four tph terminate at Edinburgh or beyond.
There is also a new and Edinburgh service from East Coast Trains, that will start this year.
- It will run five trains per day (tpd).
- It will call at Newcastle.
- It will stop at Morpeth between Newcastle and Edinburgh.
There will also be High Speed Two services to Newcastle in a few years.
- There will be two tph between Euston and Newcastle
- There will be one tph between Birmingham Curzon Street and Newcastle.
Note.
- All services will be run by 200 metre long High Speed Two Classic-Compatible trains.
- There is no High Speed Two service to Newcastle, that calls at Leeds.
- Only one High Speed Two service to Newcastle calls at East Midlands Hub.
I suspect High Speed Two services need a dedicated platform at Newcastle, especially, if another High Speed Two service were to be added.
Extra Paths For LNER
In the December 2020 Edition of Modern Railways, there is an article, which is entitled LNER Seeks 10 More Bi-Modes.
This is the last paragraph.
Infrastructure upgrades are due to prompt a timetable recast in May 2022 (delayed from December 2021), from which point LNER will operate 6.5 trains per hour out of King’s Cross, compared to five today. As an interim measure LNER is retaining seven rakes of Mk. 4 coaches hauled by 12 Class 91 locomotives to supplement the Azuma fleet and support its timetable ambitions until new trains are delivered.
There would certainly appear to be a path available if LNER wanted to increase the frequency of trains between King’s Cross and Edinburgh from the current two trains per hour (tph) to three.
I laid out how I would use this third path to Edinburgh in A New Elizabethan.
The Possible Long Distance Trains Through And To Newcastle
These trains can be summed up as follows.
- 1 tph – CrossCountry – Plymouth and Edinburgh or Glasgow via Alnmouth, Berwick-upon-Tweed and Dunbar.
- 1 tph – CrossCountry – Southampton Central or Reading and Newcastle.
- 1 tph – LNER – King’s Cross and Edinburgh via Berwick-upon-Tweed
- 1 tph – LNER – King’s Cross and Edinburgh via Alnmouth
- 1 tph – TransPennine Express – Liverpool Lime Street and Edinburgh via Morpeth
- 1 tph – TransPennine Express – Manchester Airport and Newcastle.
- 5 tpd – East Coast Trains – King’s Cross and Edinburgh via Morpeth
- 2 tph – High Speed Two – Euston and Newcastle
- 1 tph – High Speed Two – Birmingham Curzon Street and Newcastle
- 1 tph – LNER – King’s Cross and Edinburgh – Extra service
This is ten tph and the five tpd of East Coast Trains.
Capacity Between Newcastle And Edinburgh
I wonder what capacity and linespeed would be possible on the East Coast Main Line between Newcastle and Edinburgh.
There are a few freight trains and some suburban electrics at the Northern end, but I suspect that the route could handle ten tph with some upgrades.
Edinburgh As A Terminal
Consider.
- Not all trains terminate at Edinburgh, but several tpd go through to places like Aberdeen, Glasgow, Inverness and Stirling.
- Edinburgh has several shorter East-facing bay platforms, that can take five-car Class 802 trains.
- Edinburgh has undergone a lot of reconstruction in recent years, so that it can turn more trains.
I very much feel that Edinburgh could handle, at least ten tph from the South.
Conclusion
I think it would be possible to extend all trains to Newcastle to at least Edinburgh.
Would it increase passenger capacity between the two capitals?
It would certainly avoid the difficult and expensive rebuilding at Newcastle station.
A New Elizabethan
I can remember The Elizabethan, which was a steam-hauled non-stop express between London and Edinburgh between 1953 and 1961.
- The steam-hauled train took six-hours-and-a-half.
- It used to be the longest non-stop railway service in the world.
- Today, the service could be run by the current or refurbished Azumas or perhaps a new flagship train, built for the service.
- It could be easily under four hours.
It could be an interesting concept, to increase capacity between London and Edinburgh.
The Fastest Rail Journey Between London King’s Cross And Edinburgh
This section in the Wikipedia entry for the Class 91 locomotive is entitled Speed Record. This is the first paragraph.
A Class 91, 91010 (now 91110), holds the British locomotive speed record at 161.7 mph (260.2 km/h), set on 17 September 1989, just south of Little Bytham on a test run down Stoke Bank with the DVT leading. Although Class 370s, Class 373s and Class 374s have run faster, all are EMUs which means that the Electra is officially the fastest locomotive in Britain. Another loco (91031, now 91131), hauling five Mk4s and a DVT on a test run, ran between London King’s Cross and Edinburgh Waverley in 3 hours, 29 minutes and 30 seconds on 26 September 1991. This is still the current record. The set covered the route in an average speed of 112.5 mph (181.1 km/h) and reached the full 140 mph (225 km/h) several times during the run.
Seconds under three-and-a-half-hours was an amazing time nearly thirty years ago, from a short-formation InterCity 225, that went on to become the mainstay of the services on the route.
It makes High Speed Two’s proposed time of three hours and forty-eight minutes appear to lack ambition.
But to be fair to High Speed Two, train services have historically been faster on the the East side of Great Britain.
What Time Could Be Possible Between London King’s Cross And Edinburgh?
In What Is Possible On The East Coast Main Line?, I took a hard look at times on the route, taking into account improvements of the last thirty years and those that will happen in the next few.
This was my conclusion.
I started by asking what is possible on The East Coast Main Line?
As the time of three-and-a-half hours was achieved by a short-formation InterCity 225 train in 1991 before Covids, Hitchin, Kings Cross Remodelling, Power Upgrades, Werrington and lots of other work, I believe that some journeys between Kings Cross and Edinburgh could be around this time within perhaps five years.
To some, that might seem an extraordinary claim, but when you consider that the InterCity 225 train in 1991 did it with only a few sections of 140 mph running, I very much think it is a certainly at some point.
As to the ultimate time, earlier I showed that an average of 120 mph between King’s Cross and Edinburgh gives a time of 3:16 minutes.
Surely, an increase of fourteen minutes in thirty years is possible?
I believe that timings will decrease significantly on the East Coast Main Line with the current trains.
Extra Paths For LNER
In the December 2020 Edition of Modern Railways, there is an article, which is entitled LNER Seeks 10 More Bi-Modes.
This is the last paragraph.
Infrastructure upgrades are due to prompt a timetable recast in May 2022 (delayed from December 2021), from which point LNER will operate 6.5 trains per hour out of King’s Cross, compared to five today. As an interim measure LNER is retaining seven rakes of Mk. 4 coaches hauled by 12 Class 91 locomotives to supplement the Azuma fleet and support its timetable ambitions until new trains are delivered.
There would certainly appear to be a path available if LNER wanted to increase the frequency of trains between London King’s Cross and Edinburgh from the current two trains per hour (tph) to three.
What Would Be The Route?
I feel there could be three possible simple routes.
- A direct non-stop London King’s Cross and Edinburgh service.
- A London King’s Cross and Edinburgh service with a single stop at Newcastle.
- A London King’s Cross and Edinburgh service with stops at Leeds and Newcastle.
Each route would have its own advantages and drawbacks.
Route 1
My thoughts about Route 1.
- This would be the fastest route.
- It would be a serious challenge to the airlines on the London and Edinburgh route.
It would be a marketing man’s dream.
Route 2
My thoughts about Route 2.
- This would be the second fastest route.
- It would be a serious challenge to the airlines on the London and Edinburgh route.
- It would give Newcastle a third hourly service to the capital.
- It would give Newcastle a non-stop train to London every hour.
- It would probably be the fastest train between King’s Cross and Newcastle.
- It would beef up the challenge to the airlines on the London and Newcastle route.
Serving Newcastle may generate extra passengers.
Route 3
My thoughts about Route 3.
- This would be the slowest route as it is 23 miles longer.
- It would be a challenge to the airlines on the London and Edinburgh route.
- It would give Newcastle and Leeds a third hourly service to the capital.
- It would give Leeds a non-stop train to London every hour.
- It would probably be the fastest train between London and Leeds.
- It would beef up the challenge to the airlines on the London and Newcastle and London and Leeds routes.
- There could be an extra call at York
Serving Leeds and Newcastle may generate extra passengers.
Obviously, passenger numbers will determine the best route.
Conclusion
I very much feel that properly thought through, this service could be a success.
Thoughts On Faster Trains On Thameslink
The Class 700 trains used by Thameslink only have an operating speed of 100 mph.
I do wonder, if that is a fast enough operating speed for all Thameslink routes.
Sharing The Midland Main Line With 125 mph Trains
A couple of years ago, I travelled back into St. Pancras with a group of East Midlands drivers in a Class 222 train.
They told me several things about the route including that the bridge at the South of Leicester station would be difficult to electrify, as it was low and the track couldn’t be lowered as one of Leicester’s main sewers was under the tracks at the bridge. Perhaps, this is one place, where discontinuous electrification could be used on the Midland Main Line.
They also told me, that sometimes the Thameslink trains were a nuisance, as because of their 100 mph operating speed, the 125 mph Class 222 trains had to slow to 100 mph.
Upgrading Of The Midland Main Line South Of Bedford
The electrification of the Midland Main Line South of Bedford is being updated, so that it is suitable for 125 mph running.
An Analysis Of Services On The Midland Main Line South Of Bedford
The current Class 222 trains are capable of 125 mph and will be replaced by Class 810 trains capable of the same speed on both diesel and electricity.
Currently, a Class 222 train is capable of doing the following on a typical non-stop run between St. Pancras and Leicester.
- Covering the 30 miles between St. Albans and Bedford in 17 minutes at an average speed of 106 mph.
- Covering the 50.3 miles between Bedford and Leicester in 30 minutes at an average speed of 100.6 mph.
- Maintaining 125 mph for long stretches of the route, once the trains is North of London commuter traffic at St. Albans
I can estimate the timings on the 79.2 miles between Leicester and St. Albans, by assuming the train runs at a constant speed.
- 100 mph – 47.5 minutes
- 110 mph – 43.2 minutes
- 125 mph – 38 minutes
- 140 mph – 34 minutes
Note.
- I have done the calculation for 140 mph, as that is the maximum operating speed of the Class 810 train with full in-cab digital signalling.
- Trains have been running at 125 mph for a couple of decades on the Midland Main Line.
- To get a St. Pancras and Leicester time add another 14 minutes, which is the current time between St. Pancras and St. Albans of a Class 222 train.
- Some Off Peak trains are timed at 62-63 minutes between St. Pancras and Leicester.
- A time of under an hour between St. Pancras and Leicester might be possible and the Marketing Department would like it.
- As Thameslink trains between Bedford and St. Albans stop regularly, they are on the slow lines of the four-track railway, to the North of St. Albans.
- South of St. Albans, Thameslink trains often run on the fast lines.
I can expect that East Midlands Railway will want to be running their new Class 810 trains as far as far South as they can at 125 mph, to speed up their services. When the signalling allows it, they’ll want to run at 140 mph.
So they won’t want to see Thameslink’s slow trains on the fast lines.
- But if you look at the Thameslink trains that do run on the fast lines between St. Albans and St. Pancras, they appear to be the four trains per hour (tph) that run to and from Bedford.
- Of these trains, two tph terminate at Brighton and two tph terminate at Gatwick Airport.
- The average speed of a Class 222 train between St. Albans and St. Pancras assuming 14 minutes for the 19.7 miles is 84.4 mph.
So it looks to me that a 100 mph Thameslink train could be able to get away without slowing the East Midland Railway expresses.
But then that is not surprising, as for many years, the Class 222 trains worked happily with 100 mph Class 319 trains.
Is There Scope For Extra And Faster Services Into St. Pancras?
I have only done a simple calculation, but I do wonder if there is scope for the following.
- Increasing the frequency of trains for both Thameslink and East Midlands Railway.
- Saving a few minutes on East Midlands Railway services.
Consider.
- The new Class 810 electric trains will probably have better acceleration and deceleration than the current Class 222 diesel trains, when working using electric power.
- East Midlands Railway is introducing Class 360 trains that were built as 100 mph trains by Siemens, who are now upgrading them to 110 mph trains.
- Can Siemens do the same for the Class 700 trains and create a sub-fleet capable of 110 mph running?
- All trains will be running under full in-cab digital signalling with a large degree of automatic train control.
I feel that if the Class 700 trains had the extra speed, they would make the planning of services South of St. Albans easier and allow the Class 810 trains to both run faster and provide more services.
Sharing The East Coast Main Line With 125 mph Trains
The following Thameslink services run up the East Coast Main Line past Stevenage.
- Cambridge And Brighton – Two tph – Stops at Royston, Ashwell and Morden (1 tph), Baldock, Letchworth Garden City, Hitchin, Stevenage, Finsbury Park, London St Pancras International, Farringdon, City Thameslink, London Blackfriars, London Bridge, East Croydon, Gatwick Airport, Three Bridges, Balcombe, Haywards Heath and Burgess Hill
- Cambridge and Kings Cross – Two tph – Stops at Foxton, Shepreth, Meldreth, Royston, Ashwell and Morden, Baldock, Letchworth Garden City, Hitchin, Stevenage, Knebworth, Welwyn North, Welwyn Garden City, Hatfield, Potters Bar and Finsbury Park
- Peterborough and Horsham – Two tph – Stops at Huntingdon, St Neots, Sandy, Biggleswade, Arlesey, Hitchin, Stevenage, Finsbury Park, London St Pancras International, Farringdon, City Thameslink, London Blackfriars, London Bridge, East Croydon, Coulsdon South, Merstham, Redhill, Horley, Gatwick Airport, Three Bridges, Crawley, Ifield, Faygate (limited) and Littlehaven
Note.
- Services are generally run by Class 700 trains, although lately the Kings Cross service seems to use Class 387 trains, which have a maximum speed of 110 mph and a more comfortable interior with tables.
- It is intended that the Cambridge and Kings Cross service will be extended to Maidstone East by 2021.
In addition there are two Cambridge Express and Fen Line services.
- Kings Cross and Ely – One tph – Stops at Cambridge and Cambridge North.
- Kings Cross and King’s Lynn – One tph – Stops at Cambridge, Cambridge North, Waterbeach, Ely, Littleport, Downham Market and Watlington
Note.
- These services are generally run by Class 387 trains.
- Cambridge and King’s Cross is timetabled at around fifty minutes.
Adding all of this together means that slower services on the East Coast Main Line are comprised of the following in both directions.
- Three tph – 110 mph – Class 387 trains
- Four tph – 100 mph – Class 700 trains
These seven trains will have to be fitted in with the 125 mph trains running services on the East Coast Main Line, for LNER, Grand Central, Hull Trains and East Coast Trains.
There are also the following problems.
- All trains must navigate the double-track section of the East Coast Main Line over the Digswell Viaduct and through Welwyn North station.
- The King’s Cross and Cambridge service stops in Welwyn North station.
- Full in-cab digital signalling is being installed on the East Coast Main Line, which could increase the speed of the expresses through the double-track section.
Could the introduction of the Class 387 trains on the Cambridge and King’s Cross service have been made, as it easier to fit in all the services if this one is run by a 110 mph train?
However, the full in-cab digital signalling with a degree of automatic train control could be the solution to this bottleneck on the East Coast Main Line.
- Trains could be controlled automatically and with great precision between perhaps Hatfield and Stevenage.
- Some expresses might be slowed to create gaps for the Cambridge and Peterborough services.
- The Hertford Loop Line is also getting full in-cab digital signalling, so will some services be sent that way?
In Call For ETCS On King’s Lynn Route, I talked about a proposal to improve services on the Fen Line. This was my first three paragraphs.
The title of this post, is the same as that on an article in Edition 849 of Rail Magazine.
The article is based on this document on the Fen Line Users Aoociation web site, which is entitled Joint Response To Draft East Coast Main Line Route Study.
In addition to ETCS, which could improve capacity on the East Coast Main Line, they would also like to see journey time reductions using trains capable of running at 125 mph or faster on the King’s Lynn to Kings Cross route.
My scheduling experience tells me that a better solution will be found, if all resources are similar.
Hence the proposal to run 125 mph trains between King’s Cross and King’s Lynn and probably Ely as well, could be a very good and logical idea.
If the Class 700 trains were increased in speed to 110 mph, the trains through the double-track section of the East Coast Main Line would be.
- One tph – 110 mph – Class 387 trains
- Four tph – 110 mph – Class 700 trains
- Two tph – 125 mph – New trains
Note.
- This would probably be an easier mix of trains to digest with the high speed services, through the double-track section.
- I like the idea of extending the Ely service to Norwich to give Thetford, Attleborough and Wymondham an improved service to London, Cambridge and Norwich.
The new trains would probably be a version of Hitachi’s Regional Battery Train.
- It would need to be capable of 125 mph on the East Coast Main Line.
- If the Ely service were to be extended to Norwich, this section would be on battery power.
There are certainly a lot of possibilities.
But as with on the Midland Main Line, it looks like for efficient operation, the operating speed of the Class 700 trains on the route needs to be increased to at least 110 mph.
Could Faster Class 700 trains Improve Services To Brighton?
These are the Thameslink services that serve Bedford, Cambridge and Peterborough, that I believe could be run more efficiently with trains capable of at running at speeds of at least 110 mph.
- Bedford and Brighton – Two tph
- Bedford and Gatwick Airport – Two tph
- Cambridge and Brighton – Two tph
- Cambridge and Maidstone East – Two tph
- Peterborough and Horsham – Two tph
Note.
- I have assumed that the Cambridge and King’s Cross service has been extended to Maidstone East as planned.
- Eight tph serve Gatwick Airport.
- Four tph serve Brighton.
The Gatwick Express services have a frequency of two tph between London Victoria and Brighton calling at Gatwick Airport is already run by 110 mph Class 387 trains.
It would appear that if the Bedford, Cambridge and Peterborough were run by uprated 110 mph Class 700 trains, then this would mean that more 110 mph trains would be running to Gatwick and Brighton and this must surely improve the service to the South Coast.
But it’s not quite as simple as that, as the Cambridge and Maidstone East services will be run by eight-car trains and all the other services by twelve-car trains.
Conclusion
There would appear to be advantages in uprating some or possibly all of the Class 700 trains, so that they can run at 110 mph, as it will increase capacity on the Brighton Main Line, East Coast Main Line and Midland Main Line.
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.
- Long stretches of these routes allow speeds of up to 125 mph.
- Full digital in-cab ERTMS signalling is being installed on the East Coast Main Line to allow running up to 140 mph.
- 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.
- These services are run by Class 700 trains, that are only capable of 100 mph.
- The fast services take the fast lines South of the Digswell Viaduct.
- South of Finsbury Park, both fast services cross over to access the Canal Tunnel for St, Pancras station.
- 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.
- It is only a 100 mph train.
- The batteries are to be designed and manufactured by Hyperdrive Innovation.
- It has a range of 56 miles on battery power.
- 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.
- Only one engine is replaced by a battery.
- The batteries are to be designed and manufactured by Hyperdrive Innovation.
- Typically a five-car Class 800 or 802 train has three diesel engines and a nine-car train has five.
- 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.
- Reducing the consumption to 2.5 kWh per vehicle-mile would give a range of 87.3 miles.
- Reducing the consumption to 2 kWh per vehicle-mile would give a range of 109.2 miles.
- Hitachi will be working to reduce the electricity consumption of the trains.
- 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.
- An average speed of 80 mph would save seven minutes.
- An average speed of 90 mph would save twelve minutes.
- 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.
Roger Ford’s Cunning Plan
In the February 2020 of Modern Railways, there is an article called LNER Procurement, which has been written by Roger Ford.
It is Roger’s reply to an article in the December 2020 Edition of Modern Railways, which was entitled LNER Seeks 10 More Bi-Modes.
He starts by describing the requirement and then says this.
Would any fleet engineer in his or her right mind want to add a unique sub-fleet of 10 high speed trains to an existing successful fleet, even if they were hydrogen-electric tri-modes from the respected Kim Chong t’ae Electric Locomotive Works?
In my analysis of the December 2020 article, I wrote this post with the same name, where I said this, under a heading of More Azumas?
Surely, It would require a very innovative train at perhaps a rock-bottom price from another manufacturer, for LNER to not acquire extra Azumas.
So it would appear that Roger and myself are vaguely in agreement on the subject of more Azumas.
The last section of the article has a title of Cunning.
Roger puts forward, the view that the procurement process, as well as being compatible with EU law, could be a warning to Hitachi, to make sure that LNER get a good deal.
It certainly could be, and I remember a similar maneuver by ICI around 1970.
The company was buying a lot of expensive IBM 360 computers.
ICI needed a new computer to do scientific calculations at their Central Instrument Research Establishment (CIRL) at Pangbourne in Berkshire.
- English Electric had just released a clone of an IBM 360 and were keen to sell it to ICI.
- As it would do everything that ICI wanted, they bought one.
- It worked well and did everything that CIRL wanted at a cheaper price.
IBM’s reaction was supposedly quick and dramatic. The salesman who dealt with ICI, was immediately fired!
But as ICI had about a dozen large IBM computers, there wasn’t much they could do to one of the most important and largest UK companies.
IBM also made sure, that ICI got their next computer at a good price.
I’m with Roger that all the shenanigans are a warning to Hitachi.
Roger finishes the article with these two paragraphs.
A genuine bluff would have been to seek bids for the long-term deployment of remanufactured IC225s. Which in these straitened times could still turn out to be a more viable option.
I rather fancy the idea of a hydrogen-electric Class 91. Owner Eversholt Rail might even have played along on the understanding that it funded the inevitable hybrid Azumas.
Note that IC225s are InterCity 225 trains.
- The 31 trains, were built for British Rail in the 1980s.
- They are hauled by a 4.83 MW Class 91 locomotive, which is usually at the Northern end of the train.
- Nine Mark 4 coaches and a driving van trailer complete the train.
- As with the Hitachi Azumas (Class 800 and Class 801 trains), they are capable of operating at 140 mph on lines where digital in-cab ERTMS signalling has been installed.
I just wonder, if a Class 91 locomotive could be to the world’s first 140 mph hydrogen-electric locomotive.
Consider the following.
Dynamics
The wheels, bogies and traction system were designed by British Rail Engineering Ltd, who were the masters of dynamics. This is a sentence from the locomotive’s Wikipedia entry.
Unusually, the motors are body mounted and drive bogie-mounted gearboxes via cardan shafts. This reduces the unsprung mass and hence track wear at high speeds.
That is a rather unique layout. But it obviously works, as otherwise these locomotives would have been scrapped decades ago.
I believe the quality dynamics are because BREL owned a PACE 231R for a start, which was an analogue computer, that was good enough for NASA to use two computers like this to calculate how to put a man on the moon.
London and Edinburgh is a slightly shorter distance, run at a somewhat slower speed.
Space
This picture shows a Class 91 locomotive.
What is in the space in the rear end of the nearly twenty metre-long locomotive?
This sentence from the Wikipedia entry for the locomotive gives a clue.
The locomotive also features an underslung transformer, so that the body is relatively empty compared to contemporary electric locomotives.
It also states that much of the layout came from the APT-P, which was a version of the tilting Advanced Passenger Train.
Would the space be large enough for a tank of hydrogen and some form of generator that used the hydrogen as fuel?
It should be noted that one version of the APT used a gas-turbine engine, so was the locomotive designed for future use as a bi-mode?
Fuel Cells
I’ve ignored fuel cells, as to get the amount of power needed, the fuel cells could be too large for the locomotive.
Class 91 Locomotive Performance
The performance of a Class 91 locomotive is as follows.
- Power output – 4.83 MW
- Operating speed – 140 mph
- Record Speed – 161 mph
Not bad for a 1980s locomotive.
Required Performance Using Hydrogen Fuel
If the locomotives were only needed to use hydrogen to the North of the electrification from London, the locomotive would need to be able to haul a rake of coaches twice on the following routes.
- Aberdeen and Edinburgh Haymarket – 130 miles
- Inverness and Stirling – 146 miles
A range of three hundred miles would be sufficient.
The locomotive would need refuelling at Aberdeen and Inverness.
The operating speed of both routes is nowhere near 140 mph and I suspect that a maximum speed of 100 mph on hydrogen, pulling or pushing a full-size train, would probably be sufficient.
When you consider that a nine-car Class 800 train has five 560 kW diesel engines, that give a total power of 2.8 MW, can carry 611 passengers and an InterCity 225 can only carry 535, I don’t think that the power required under hydrogen will be as high as that needed under electricity.
Rolls-Royce
Rolls-Royce have developed a 2.5 MW generator, that is the size of a beer keg. I wrote about it in Our Sustainability Journey.
Could one of these incredibly-powerful generators provide enough power to speed an InterCity 225 train, through the Highlands of Scotland to Aberdeen and Inverness, at speeds of up to 100 mph.
I would give it a high chance of being a possible dream.
Application Of Modern Technology
I do wonder, if the locomotive’s cardan shaft drive could be improved by modern technology.
These pictures show Joseph Bazalgette’s magnificent Abbey Mills Pumping station in East London.
A few years ago, Thames Water had a problem. Under the pumping station are Victorian centrifugal pumps that pump raw sewage to Beckton works for treatment. These are connected to 1930s electric motors in Dalek-like structures on the ground floor, using heavy steel shafts. The motors are controlled from the control panel in the first image.
The shafts were showing signs of their age and needed replacement.
So Thames Water turned to the experts in high-power transmission at high speed – Formula One.
The pumps are now connected to the electric motors, using high-strength, lower-weight carbon-fibre shafts.
Could this and other modern technology be used to update the cardan shafts and other parts of these locomotives?
Could The Locomotives Use Regenerative Braking To Batteries?
I’ll start by calculating the kinetic energy of a full InterCity 225 train.
- The Class 91 locomotive weighs 81.5 tonnes
- Nine Mark 4 coaches weigh a total of 378 tonnes
- A driving van trailer weighs 43.7 tonnes.
- This gives a total weight of 503.2 tonnes.
Assuming that each of the 535 passengers, weighs 90 Kg with babies, baggage, bikes and buggies, this gives a passenger weight of 48.15 tonnes or a total train weight of 551.35 tonnes.
Using Omni’s Kinetic Energy Calculator, gives the following values at different speeds.
- 100 mph – 153 kWh
- 125 mph – 239 kWh
- 140 mph – 300 kWh
I think, that a 300 kWh battery could be fitted into the back of the locomotive, along with the generator and the fuel tank.
With new traction motors, that could handle regenerative braking, this would improve the energy efficiency of the trains.
Sustainable Aviation Fuel
Sustainable aviation fuel produced by companies like Altalto would surely be an alternative to hydrogen.
- It has been tested by many aerospace companies in large numbers of gas turbines.
- As it has similar properties to standard aviation fuel, the handling rules are well-known.
When produced from something like household waste, by Altalto, sustainable aviation fuel is carbon-neutral and landfill-negative.
ERTMS Signalling And Other Upgrades
Full ERTMS digital signalling will needed to be fitted to the trains to enable 140 mph running.
Conclusion
I believe it is possible to convert a Class 91 locomotive into a hydrogen-electric locomotive with the following specification.
- 4.83 MW power on electricity.
- 140 mph on electrification
- 2.5 MW on hydrogen power.
- 100 mph on hydrogen
- Regenerative braking to battery.
If it were easier to use sustainable aviation fuel, that may be a viable alternative to hydrogen, as it is easier to handle.
