The Data Sheet For Hitachi Battery Electric Trains

Was I just slow to spot this data sheet or has it only just been released?

You can download a copy from this page on the Hitachi web site.

In a section on the page, which is entitled Intercity Battery Trains, this is said.

A quick and easy application of battery technology is to install it on existing or future Hitachi intercity trains. Adding just one battery reduces emissions by more than 20% and offers cost savings of 20-30%.

Our intercity battery powered trains can cover 70km on non-electrified routes, operating at intercity speeds at the same or increased performance. Hitachi Rail’s modular design means this can be done without the need to re-engineer or rebuild the train and return them to service as quickly as possible for passengers.

These are my initial thoughts.

Plug-and-Play

It looks like the train is plug-and-play.

A diesel engine will be swapped for a battery-pack and the train’s computer controls the power sources accordingly.

Hitachi’s Battery Philosophy Explained

This is said on the data sheet.

Battery technology has the potential to play a significant role in the future of sustainable rail mobility, setting
the rail industry on the path to full intercity decarbonisation by 2050.
Installing batteries on intercity trains can complement electrification and provide a low emission alternative
to domestic air travel.

Our retrofit solution for intercity trains offers phased replacement of diesel engines at the time that they would
have been due for their regular heavy maintenance overhaul, replacing each engine in turn until trains are fully battery electric. The solution delivers fuel cost savings and lowers CO2 emissions by at least 20% for every engine replaced, and a 20% reduction in whole life maintenance costs – well within the battery’s life span of 8-10 years.

Performance On Battery Power

The data sheet gives these bullet points.

  • 750kW peak power
  • Weight neutral.
  • At least 20% lower CO2 emissions
  • 70km on non-electrified routes
  • 20% reduction in whole life maintenance costs
  • Up to 30% fuel cost savings
  • Zero emissions in and out of stations
  • Charge on the move
  • 10 year life span

Note.

  1. 750 kW peak power, is around the power of the diesel-engine, that will be replaced.
  2. I wouldn’t be surprised that powerwise, the battery pack looks like a diesel engine.
  3. Weight neutral means that acceleration, performance and handling will be unchanged.
  4. Batteries are easier to maintain than diesels.
  5. It is stated that a train can be fully-decarbonised.

I have a feeling these trains are no ordinary battery-electric trains.

Seventy Kilometre Range On Battery

Seventy kilometres is 43.5 miles.

This may not seem much, but the data sheet says this.

Our battery hybrid trains can cover 70km on non-electrified routes, operating at intercity speeds at the same
or increased performance. By identifying the routes with short non-electrified sections of 70km or less, we could
see the replacement of existing diesel trains with fully battery-operated trains on those routes within a year.
And, using battery power to avoid electrifying the hardest and most expensive areas, such as tunnels and bridges,
enables flexibility on electrification, minimising passenger disruption during upgrades.

Note.

  1. It looks like the trains can operate at 125 mph on battery power, where the track allows it. But then the rolling restistance of steel wheel on steel rail, is much lower, than that of rubber tyres on tarmac.
  2. Hitachi seem to have developed a philosophy on how the trains will be used.
  3. Hitachi’s pantographs, go up and down with all the alacrity of a whore’s drawers. They will be ideal for a short length of electrification.

I think these LNER routes could be immediately decarbonised.

  • LNER – London and Harrogate , where only 18.3 miles is unelectrified. Trains may not need charging, as a full battery could handle both ways.
  • LNER – London and Hull, where 36.1 miles is unelectrified. A short length of electrification to charge trains would be needed at Hull.
  • LNER – London and Lincoln, where only 16.7 miles is unelectrified. Trains would not need charging, as a full battery could handle both ways.
  • LNER – London and Middlesbrough, where only 20.3 miles is unelectrified. Trains would not need charging, as a full battery could handle both ways.

Note.

  1. It looks like some services could start fairly soon, once batteries are available.
  2. Hull Trains could use the 70 km batteries and charging at Hull, as it passed through. This would decarbonise Hull Trains passenger operations.
  3. Services to Aberdeen, Cleethorpes and Inverness would be out of range of the initial Hitachi trains.

Could the last point, partially explain the purchase of the CAF tri-mode trains, which I wrote about in First Tri-Mode Long Distance Trains For The East Coast Main Line?

We shall see what we shall see.

But having a choice of battery-electric or tri-mode trains will enable route development and decarbonisation.

What Is The Size Of The Battery Pack?

In How Much Power Is Needed To Run A Train At 125 Or 100 mph?, I estimated that to maintain 125 mph, a Class 801 train has a usage figure of 3.42 kWh per vehicle mile.

If a five-car Class 800 can run 70 km or 43.5 miles at 125 mph, as indicated by Hitachi, then the battery size can be calculated.

3.42 * 5 * 43.5 = 743.85 kWh

As the battery pack can supply 750 kW according to the data sheet, this looks like this will run the train for an hour.

Is that coincidence or a design criteria?

What Battery Capacity Would Be Needed For A Hundred Miles?

For a five-car train, this is the energy needed for a hundred miles.

3.42 *5 * 100 = 1710 kWh or three batteries.

For a nine-car train, this is the energy needed for a hundred miles.

3.42 *9 * 100 = 3078 kWh or five batteries.

It looks like all diesel engines will be replaced by batteries.

Will Class 801 Trains Swap Their Single Diesel Engine For a Battery Power Pack?

Consider.

  • Class 801 trains have a single diesel engine for emergency power.
  • Lumo’s Class 803 trains, are all-electric with a battery-pack for emergency hotel power only.
  • Hitachi must have full details on the performance of Lumo’s trains.
  • The East Coast Main Line is notorious for the wires to come tumbling down.
  • The diesel engine and the battery pack appear to weigh the same.
  • Batteries cost less to maintain than diesels.

I can’t see why the single diesel engine can’t be replaced by a standard battery pack, without loosing any functionality.

What Would Be The Range Of A Fully Battery-Electric Train?

This is a paragraph from a data sheet.

Our retrofit solution for intercity trains offers phased replacement of diesel engines at the time that they would
have been due for their regular heavy maintenance overhaul, replacing each engine in turn until trains are fully battery electric. The solution delivers fuel cost savings and lowers CO2 emissions by at least 20% for every engine replaced, and a 20% reduction in whole life maintenance costs – well within the battery’s life span of 8-10 years.

Note.

  1. It looks like Hitachi are expecting operators to replace engines in turn.
  2. Replacing engines with batteries saves the operators money.

As a five-car Class 800 train has three diesel engines and a nine-car train has five engines, does this mean that the range of fully-batteried Class 800 train is 70 km or 210 km?

  • A fully-batteried Class 800 train will weigh the same as the current diesel.
  • One battery can drive the train for 70 km at 125 mph according to Hitachi.
  • There are no branches of electrified lines that are 125 mph lines without electrification.
  • I would assume that the train can use regenerative braking to recharge the batteries.
  • 210 kilometres is 130 miles.

I don’t know much about the electrical systems of Hitachi’s trains, but it is likely that there will be an electrical bus to distribute power from one end of the train to the other.

So a five-car Class 800 train with three fully-charged battery packs could have over 2 MWh of electricity on board, that could be used for traction.

  • Applying the usage figure of 3.42 kWh per vehicle mile, gives a range for the five-car train of at least 117 miles.
  • The equivalent figure for a nine-car train will be at least 121 miles.

These distances would open up routes like these on the East Coast Main Line.

  • LNER – London King’s Cross and Aberdeen – 91.4 miles – Charge before return.
  • LNER/Hull Trains – London King’s Cross and Beverley via Temple Hirst junction – 44.3 miles – No Charging needed before return.
  • Grand Central – London King’s Cross and Bradford Interchange via Shaftholme junction – 47.8 miles – No Charging needed before return.
  • LNER – London King’s Cross and Cleethorpes via Newark and Lincoln – 63.9 miles – Charge before return.
  • LNER – London King’s Cross and Harrogate via Leeds – 18.3 miles – No Charging needed before return.
  • LNER – London King’s Cross and Inverness– 146.2 miles – Charge before return.
  • LNER/Hull Trains – London King’s Cross and Hull via Temple Hirst junction – 36.1 miles – No Charging needed before return.
  • LNER – London King’s Cross and Middlesbrough via Northallerton – 20.3 miles – No Charging needed before return.
  • LNER – London King’s Cross and Scarborough via York – 42.1 miles – No Charging needed before return.
  • LNER/Grand Central – London King’s Cross and Sunderland via Northallerton – 47.4 miles – No Charging needed before return.

Note.

  1. The miles are the longest continuous distance without electrification.
  2. Only Aberdeen, Cleethorpes and Inverness would need to charge trains before return.
  3. Inverness may be too far. But is it in range of LNER’s new CAF tri-mode trains?

The battery range  would also allow LNER to use the Lincoln diversion on the Joint Line.

Why Didn’t LNER Buy More Azumas?

This puzzles me and I suspect it puzzles other people too.

Surely, an all Azuma fleet will be easier to manage.

But in this article on Modern Railways, which is entitled LNER Orders CAF Tri-mode Sets, this is said.

Modern Railways understands the new fleet will be maintained at Neville Hill depot in Leeds and, like the ‘225’ sets, will be used predominantly on services between London and Yorkshire, although unlike the ‘225s’ the tri-modes, with their self-power capability, will be able to serve destinations away from the electrified network such as Harrogate and Hull.

Note.

  1. Hull would possibly need work to provide some form of charging for battery-electric Azumas, but Harrogate is close enough to be served by a one-battery Azuma.
  2. The CAF Tri-mode sets would certainly handle routes like Cleethorpes, Middlesbrough and Sunderland, but would they really need a ten-car train.
  3. Ten-car trains would also be busy on the Leeds route.
  4. The UK is going to need more 125 mph trains for Cross Country, Grand Central, Grand Union, TransPennine Express and possibly other train companies.
  5. Has Hitachi got the capacity to build the trains in the UK?

So has the Government given the order to CAF to create a level of competition?

Conclusions

These are my conclusions about Hitachi’s battery packs for Class 80x trains, which were written in November 2023.

  • The battery pack has a capacity of 750 kWh.
  • A five-car train needs three battery-packs to travel 100 miles.
  • A nine-car train needs five battery-packs to travel 100 miles.
  • The maximum range of a five-car train with three batteries is 117 miles.
  • The maximum range of a nine-car train with five batteries is 121 miles.

As battery technology gets better, these distances will increase.

Hitachi have seen my figures.

They also told me, that they were in line with their figures, but new and better batteries would increase range.

In July 2025, I wrote Batteries Ordered For Grand Central Inter-City Trains, which mentions the following.

  • Grand Central’s trains will be electric-diesel-battery hybrid inter-city trainsets.
  • The trains will have lithium ion phosphate batteries.
  • The trains will be delivered in 2028.
  • The batteries will be smaller and more powerful, than current batteries.

This is also said about safety, hazards and cybersecurity.

The Safety Integrity Level 2 and IEC 61508 compliant battery management system will detect and mitigate hazards and meet the IEC 62243 cybersecurity standard.

These batteries would appear to give Hitachi and Grand Central Trains everything they want and need.

It looks like the new battery chemistry, will give Hitachi extra range.

First Tri-Mode Long Distance Trains For The East Coast Main Line

The title of this post, is the same as that of this press release from LNER.

This is the sub-heading.

London North Eastern Railway (LNER) is pleased to confirm that CAF has been named as the successful bidder to deliver a fleet of 10 new tri-mode trains for LNER. Porterbrook has been chosen as the financier of the new fleet. The trains will be able to operate in electric, battery or diesel mode.

These are the first two paragraphs.

Benefits of tri-mode trains range from a reduction in emissions, particulates, noise and vibration pollution, lower maintenance and operating costs and upgradeable technology, with an expected increase in range and performance as technology develops further. Battery power reduces the need to use diesel traction in areas where overhead powerlines are not available.

Complementing the modern Azuma fleet of 65 trains, the new ten-coach trains will help LNER achieve its vision of becoming the most loved, progressive and trusted train operator in the UK, delivering an exceptional service for the customers and communities served along its 956-mile network.

I have a few thoughts.

Will The Trains Have Rolls-Royce mtu Diesel Engines?

Consider.

  • CAF’s Class 195, 196 and 197 Civity trains for the UK all have Rolls-Royce mtu diesel engines.
  • Porterbrook are headquartered in Derby.
  • Rolls-Royce are headquartered in Derby.
  • In Rolls-Royce And Porterbrook Agreement Will Drive Rail Decarbonisation, I talked about how the two companies were planning to  decarbonise trains using techniques like mtu Hybrid PowerPacks and hydrogen fuel cells.

I would think it very likely that the new trains will have Rolls-Royce mtu engines.

Will The Trains Have Rolls-Royce mtu Hybrid PowerPacks?

It was in 2018, that I first wrote about mtu Hybrid PowerPacks in Rolls-Royce And Porterbrook Launch First Hybrid Rail Project In The UK With MTU Hybrid PowerPacks.

  • Examples of these power packs are now running in Germany, Ireland and the UK.
  • The mtu Hybrid PowerPack how has its own web site.
  • There is also this YouTube video.
  • If CAF use off-the-shelf mtu Hybrid PowerPacks in their Civity trains, there is one big massive plus – They don’t have to develop the complicated control software to get a combination of diesel engines and batteries to perform as immaculately as Busby Berkeley’s dancers or a Brigade of Guards.
  • The mtu Hybrid PowerPacks also have a big plus for operators – The batteries don’t need separate charging infrastructure.
  • In Rolls-Royce Releases mtu Rail Engines For Sustainable Fuels, I talk about how mtu engines can run on sustainable fuels, such as biodiesel or HVO.

I think it is extremely likely that CAF’s new trains for LNER will be powered by mtu Hybrid PowerPacks.

Class 800 And Class 397 Trains Compared

The Class 800 train is LNER’s workhorse to Scotland from London.

The Class 397 train used by TransPennine Express, is a 125 mph Civity train.

Differences include.

  • The Class 800 train can run at 140 mph, where the signalling allows, but is the Class 397 train only capable of 125 mph?
  • The Class 397 train accelerate at 0.92 m/s², whereas the Class 800 train can only manage 0.7 m/s².
  • The Hitachi train has 14 % more seats, 36 First and 290 Standard as opposed to 22 First and 264 Standard in five-car trains.

I will add to this list.

Will The New Trains Be Capable Of 140 mph Running?

As the East Coast Main Line is being fully digitally signalled to  allow 140 mph running of the numerous Hitachi expresses on the route, I wouldn’t be surprised to see, that the new CAF trains will be capable of 140 mph.

In this article on Modern Railways, which is entitled LNER Orders CAF Tri-mode Sets, this is said.

The new fleet will be equipped with CAF Signalling’s European Rail Traffic Management System digital signalling. This will align with the East Coast Digital Programme, which aims to introduce European Train Control System (ETCS) on the southern stretch of the East Coast main line from King’s Cross to Stoke Tunnel by 2029.

Later in the article this is said.

LNER has retained 12 ‘91s’ hauling eight rakes of Mk 4s, and the rollout of ETCS is another reason the operator has sought to order the replacement fleet. LNER’s passenger numbers have rebounded more quickly than other operators post-Covid, which has helped make the case for confirming the order.

This does seem sensible.

What Will Be The Range Of The CAF Trains Without Electrification?

The longest LNER route without electrification is the Northern section of the Inverness service between Inverness and Dunblane, which is 146.1 miles. There are also eight stops and some hills.

In Edinburgh to Inverness in the Cab of an HST, there’s a video of the route.

I’m sure that even, if they don’t normally run the new trains to Inverness, being able to do so, could be useful at some point.

It should be noted that the Guinness World Record for battery-electric trains is 139 miles, which is held by a Stadler Akku.

I am left with the conclusion that London and Inverness needs a tri-mode train or lots of electrification. Did this rule out Hitachi?

The Number Of Trains Ordered

The Modern Railways article says this about the number of trains.

The contract includes an eight-year maintenance services agreement with an option to extend; CAF says the order value, including maintenance, exceeds €500 million. When the tender was published the intention was to include an option for five additional sets; LNER confirmed to Modern Railways there is an option to purchase additional sets on top of the base order of 10.

Can we assume this means that other trains will be ordered, if the trains are a success?

Can These New CAF Trains Be Made Net Zero?

This is a paragraph, in the LNER press release.

This new fleet of trains will keep LNER on track to reduce its emissions by 67 per cent by 2035 and be net zero by 2045. LNER has already reduced carbon emissions by 50 per cent compared with 2018/19. Per mile, LNER trains produce 15 times less carbon emissions than a domestic flight.

As the new CAF trains will probably have a service life of at least forty years, there must be some way, that these new trains can be made net zero.

Consider.

  • I am absolutely certain, that the new CAF trains will have Rolls-Royce mtu diesel engines.
  • LNER’s existing Class 800 and 801 trains have Rolls-Royce mtu diesel engines.

Rolls-Royce mtu according to some of Rolls-Royce’s press releases appear to be developing net zero solutions based on hydrogen or net zero fuels.

This press release from Rolls-Royce is entitled Rolls-Royce Successfully Tests mtu Engines With Pure Hydrogen, suggests that Rolls-Royce mtu are working on a solution.

Routes They Will Serve

The Modern Railways article says this about the routes to be served.

Modern Railways understands the new fleet will be maintained at Neville Hill depot in Leeds and, like the ‘225’ sets, will be used predominantly on services between London and Yorkshire, although unlike the ‘225s’ the tri-modes, with their self-power capability, will be able to serve destinations away from the electrified network such as Harrogate and Hull.

Note.

  1. This surprised me, as I’d always expected the Yorkshire routes will be served by Hitachi battery-electric trains.
  2. But it does look that both Harrogate and Hull stations, have long enough platforms to hold a ten-car train.
  3. With their tri-mode technology, it also looks like the CAF trains won’t be needed to be charged before returning to London.

The last point would enable them to try out new routes.

These are distances from the electrification of the East Coast Main Line of the destinations that LNER served, where there is not full electrification.

  • Aberdeen via Ladybank – 91.4 miles
  • Carlisle via Skipton – 86.8 miles
  • Cleethorpes via Newark and Lincoln – 63.9 miles
  • Harrogate via Leeds – 18.3 miles
  • Huddersfield via Leeds – 17.2 miles
  • Hull via Temple Hirst junction – 36.1 miles
  • Inverness via Dunblane – 146.1 miles
  • Lincoln via Newark – 16.7 miles
  • Middlesbrough via Northallerton – 22.2 miles
  • Scarborough via York – 42.1 miles
  • Sunderland via Northallerton – 47.4 miles

Note.

  1. The first place after the ‘via’ is where the electrification ends.
  2. Carlisle could be a possibility during High Speed Two upgrading of the West Coast Main Line or for an enthusiasts’ special or tourist train.
  3. Cleethorpes is a possible new service for LNER. I wrote about this in LNER To Serve Cleethorpes.
  4. Scarborough must be a possible new service for LNER.
  5. All stations can take ten-car trains, with the possible exception of Middlesbrough, which is currently being upgraded.
  6. Huddersfield and Leeds is being electrified under the TransPennine Upgrade.

This would appear to show that LNER need enough bi-mode or tri-mode trains to run services to Aberdeen, Cleethorpes, Harrogate, Hull, Inverness, Lincoln, Middlesbrough and Sunderland.

But.

  • It would appear that the initial batch of trains, will not be serving the North of Scotland.
  • Aberdeen and Inverness could be served, when there is enough electrification at the Southern end.

I am also fairly sure, that no significant infrastructure is required.

Do Hitachi Have A Problem?

I am starting to wonder, if Hitachi are having trouble with the designing and building of their battery packs.

  • It’s not like Hitachi to allow someone to run off with a €500 million contract from under their nose.
  • Are they short of capacity to build the trains at Newton Aycliffe?

But then they’re probably up to their elbows in work on the High Speed Two Classic-Compatible trains.

Are There Any Other Routes, Where The New CAF  Trains Could Be Employed?

The trains would certainly be suitable for these routes.

  • Chiltern – InterCity services.
  • CrossCountry Trains – Fleet replacement
  • Grand Central Trains – Fleet replacement
  • Grand Union Trains – For Carmarthen and Stirling open access services.
  • Great Western Railway – Replacing Castles in the South West.
  • ScotRail – Replacing Inter7City trains.
  • South Western Railway – Basingstoke and Exeter St. Davids and other routes.

Note.

  1. CAF could sell a lot of trains.
  2. I estimate that fleet replacement for Grand Central Trans would cost around €350 million
  3. The specification would vary according to the route.

Could CAF  have got the LNER order, because they have the capacity in the Newport factory?

Conclusion

It looks like CAF have done a good job in designing the trains.

I’m also fairly sure that CAF are using Rolls-Royce mtu PowerPacks.

Lumo Carbon Data Shows Its Trains Are 22 Times Greener Than Flying

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

These paragraphs detail how the figures were obtained.

To mark the second anniversary of its branding as ‘Lumo’, the operator commissioned consultancy firm Arup to provide an independent report about all direct emissions from its operations; emissions from the grid-supplied energy it uses; and other emissions in its supply chain.

Scope 1: Direct emissions from operations that are owned and controlled by Lumo;
Scope 2: Emissions from the use of grid-supplied electricity, heat, steam and/or cooling by Lumo;
Scope 3: All other emissions that occur in the value chain of Lumo.

In the last two years, Lumo has carried over two million passengers. The figures reveal that, per passenger, emissions from a London-to-Edinburgh journey are twenty-two times the level for flying (149 kgCO2e) than for using Lumo (6.8kgCO2e).

I have a few thoughts.

Carbon Savings With LNER

LNER’s Class 801 trains are similar to Lumo’s Class 803 trains.

The main difference, is that the LNER have emergency diesel engines, whereas Lumo have emergency batteries to run the trains systems, if the catenary goes down.

So LNER on balance will generate a bit more carbon than Lumo.

But the difference will be marginal.

Carbon Savings With Avanti West Coast

Avanti’s Class 390 trains to Scotland, are all-electric, so there will be a carbon-saving.

Probably about the same as with LNER.

Avanti West Coast’s New Class 807 Trains

If the Class 807 trains were cars, they would be Lotuses.

  • They are electric only and have no heavy diesel engines or traction batteries.
  • They don’t even have emergency batteries for when the catenary fails.
  • They have a redesigned nose. Is it more aerodynamic?
  • The heavy tilt mechanism is history.
  • As with all the other Hitachi high speed trains, they are capable of 125 mph, or 140 mph if the signalling permits.

These trains will undoubtedly have faster acceleration and deceleration and could probably knock minutes off the timings at all the stops.

Tucked away beside the Grand Union Sets Out Stirling Ambitions article in the December 2022 Edition of Modern Railways is a report on Avanti West Coast’s application for a second service between Euston and Liverpool.

This is said.

Avanti West Coast has applied for access rights for its second hourly Euston to Liverpool service, starting from December 2023, although a phased introduction of the new service is likely. This would make use of Avanti’s new fleet of 10×7-car Class 807 Hitachi EMUs, which are expected to enter service from Autumn 2023. The ‘807s’ would be deployed on the current hourly Liverpool service, on which a call at Liverpool South Parkway would be added. (provision is made for this in the December 2022 timetable.).

Pendolinos would then operate the second service each hour, calling at Lichfield Trent Valley and Tamworth.

A linespeed project is in progress to raise the permissible speed for non-tilting trains on the West Coast Main Line, and Avanti’s new Hitachi trains will take advantage of this.

I can’t wait to go to Liverpool in one of these trains.

Their  carbon emissions should be in line with Lumo.

Avanti West Coast’s New Class 805 Trains

These are equivalent to the Class 802 trains, but with probably Class 807 train interiors and looks.

I wonder how long these trains will keep their diesel engines before battery power is the most affordable option.

Once they go battery-electric, their  carbon emissions should be in line with Lumo.

Conclusion

I can’t see any other mantra than.

Electric good, diesel bad

Especially, if like most computers, it’s just plug and play.

Improving Trains Between London And Bradford

Current Services Between London And Bradford

LNER services run between Kings Cross  and Bradford Forster Square stations.

  • Two trains per day (tpd) run between Bradford and London in the early morning.
  • Two tpd run between London and Bradford in the evening.
  • Trains take two and three-quarter hours.
  • Stops are at Shipley, Leeds, Wakefield Westgate, Doncaster, Retford Grantham and Stevenage.
  • Trains seem to be generally a pair of five-car Class 801 trains.

Note.

  1. Trains reverse at Leeds.
  2. The timetable seems a bit lopsided, as there is no early morning train to Bradford or an evening one to London.
  3. Harrogate gets a one train per two hours (tp2h) service to and from London.

The timetable could do with an improvement.

Grand Central services run between Kings Cross  and Bradford Interchange stations.

  • Four tpd run between Bradford and London.
  • Four tpd run between London and Bradford.
  • Trains take three and a quarter hours.
  • Stops are at Pontefract Monkhill, Wakefield Kirkgate, Mirfield, Brighouse, Halifax and Low Moor
  • Trains are five-car Class 180 trains, which have seen better days.

Note.

  1. The timetable seems a bit lopsided, as there is no early morning train to Bradford or an evening one to London.

The timetable and the trains could do with an improvement.

LNER’s New Ticketing And Nine-Ten Car Trains

LNER have introduced the selling of  Advanced Tickets from machines or the Booking Office as late as five minutes before the train leaves.

  • My last three trips from Leeds to London cost me £33.55, £33.75 and £33.55 with my Senior Railcard.
  • All were bought less than ten minutes before the train left.
  • In two of the journeys, I spread out in two seats
  • Trains were either a pair of five-car Class 801 trains or a nine-car InterCity 225.

I took these pictures after my last return from Leeds on Tuesday.

Note.

  1. Two of the three trains I’ve taken lately have arrived 3-4 minutes early.
  2. Not a great increase, but I do wonder if LNER are seeing what is possible with the new digital signalling.
  3. The British Rail era; InterCity 225 seems to hold its own against the new Hitachi train.

I wouldn’t be surprised that LNER intend to both run high-capacity trains between London and Leeds and fill them by competitive pricing.

A Grand Central Train Failure On Tuesday

This was my journey to Bradford on Tuesday,

  • I was supposed to take the 1057 Grand Central service to Bradford Interchange, where it was timed to arrive at 1400.
  • But the train didn’t run and we were all advised to get on the 1103 to Leeds and change at Doncaster.
  • We arrived at Doncaster in Platform 4, a minute late at 1240 and got straight on a Grand Central train in the opposite Platform 6.
  • We left Doncaster at 1251, which was sixteen minutes late.
  • But we arrived in Bradford Interchange more or less on time at 1401.

Despite leaving six minutes late from Kings Cross and changing trains at Doncaster, we arrived at Bradford on time.

Battery-Electric Trains Between London and Bradford Interchange

I feel that my journey on Tuesday indicated.

  • Electric trains between London and Doncaster can easily meet the current timetable.
  • The Grand Central train went between Doncaster and Bradford Interchange was sixteen minutes faster than the timetable.

I wouldn’t be surprised that London and Bradford Interchange could be a few minutes under three hours.

Consider.

  • It has been said that between Bradford Interchange and Leeds will be electrified.
  • Bradford Interchange and Doncaster does not have electrification, but is only 52 miles.
  • Electrification of Bradford Interchange station, will allow battery-electric trains to be charged in around 10-12 minutes.
  • Most inter-city battery-electric trains have a battery range of at least eighty miles.
  • Digital signalling is being installed between London and Doncaster to allow 140 mph running and more trains in the timetable.

I believe that a battery-electric train with sufficient range, charging South of Doncaster and at Bradford Interchange could go between London and Bradford Interchange in 5-10 minutes under three hours.

Bradford Interchange and all the other stations North of Doncaster on the route could probably also have a one tp2h service to and from London and the South.

Splitting And Joining Of Trains

Consider.

  • Pairs of the Hitachi Class 801 trains have the ability to split and join en route, during a station stop extended by a few minutes.
  • Platforms are long enough to handle splitting and joining at Doncaster, Leeds and York.
  • Currently, three services to and from London go past Leeds; Bradford Forster Square, Harrogate and Skipton. All these services reverse in Leeds station, when they pass through.
  • The reversing in Leeds station takes about 8-9 minutes.
  • The track between Leeds and Bradford Forster Square is electrified.
  • Leeds and Harrogate is not electrified and is 19.3 miles.
  • The track between Leeds and Skipton is electrified.
  • Bradford Forster Square has a service of two tpd.
  • Harrogate has a service of one tp2h.
  • Skipton has a service of one  tpd.

In the Wikipedia entry for LNER, this is said.

From December 2019, LNER introduced a Harrogate to London service six times a day. LNER expected to introduce two-hourly services to Bradford and a daily service to Huddersfield by May 2020 when more Azuma trains had been introduced, however the latter has not yet been introduced.

Note.

  1. The Huddersfield service would have to reverse in Leeds station, like those to Bradford Forster Square, Harrogate and Skipton.
  2. Leeds and Huddersfield is not electrified and is 17.1 miles.
  3. Leeds and Huddersfield is being electrified.

Could LNER’s plan be to give Bradford Forster Square, Harrogate, Huddersfield and Skipton stations a two-hourly service , as the Wikipedia extract indicated, they intend to do for Bradford?

  • All trains enter and leave Leeds to and from the West.
  • Pairs of five-car trains would split and join at Leeds.
  • Bradford Forster Square and Skipton services would be served by electric trains.
  • Harrogate and Huddersfield services would be served by bi-mode or battery-electric trains.
  • Horsforth, Keighley and Shipley could also get a one tp2h service to London.

It looks like services via Leeds could be much improved.

In a two-hour period the Leeds area will have the following trains to and from London Kings Cross.

  • Two trains between London and Leeds via Peterborough, Doncaster and Wakefield Westgate
  • One train between London and Bradford Forster Square via Stevenage, Grantham, Retford (Bradford-bound only), Doncaster, Wakefield Westgate, Leeds and Shipley.
  • One train between London and Harrogate via Stevenage, Grantham, Doncaster, Wakefield Westgate, Leeds and Horsforth
  • One train between London and Huddersfield via Stevenage, Grantham, Doncaster, Wakefield Westgate and Leeds
  • One train between London and Skipton via Peterborough, Newark Northgate, Doncaster, Wakefield Westgate, Leeds, Shipley (London-bound only) and Keighley.

Note.

  1. Stops between London and Leeds would be adjusted to satisfy passenger numbers.
  2. Currently, there are a total of four trains in a two hour period.
  3. Six trains will be fitted in by having two London and Leeds trains and two pairs of five-car trains, that joined and split at Leeds.

There is still only four train paths needed in a two hour period between London and Leeds.

Digital Signalling Between London And Doncaster

The East Coast Digital Programme has its own web site, which gives this introduction to the programme.

The East Coast Digital Programme is delivering the next generation of train travel – creating a better performing East Coast Main Line for passengers and everyone else who uses and depends on it.

As part of the programme, traditional lineside signals will be removed and replaced with state-of the art digital signalling to improve the reliability of the train service.

The new technology continuously communicates with each train, providing signalling information directly to a computer screen in the driver’s cab. It boosts reliability, reduces carbon emissions and provides a more punctual service for customers.

In the first stage, digital signalling will be introduced on the Northern City Line, between Finsbury Park and Moorgate. It will then be progressively rolled out on the southern section of the East Coast Main Line (between London King’s Cross and the Stoke Tunnels, near Grantham).

It is expected that the first trains to operate on the East Coast Main Line using digital signalling technology will run in 2025, with all improvements expected to be completed by the end of the decade.

As a result of this programme, the East Coast Main Line will be GB’s first intercity mainline to be upgraded to digital. It lays the foundation for further improvements across the network, creating a more efficient railway fit for the future.

There is also a video.

Benefits of digital signalling will include.

  • 140 mph running instead of 125 mph.
  • An increase in the number of train paths.
  • Trains will be able to be run closer together.

As a Graduate Control Engineer, I also believe that digital signalling will enable better control of trains through bottlenecks.

A computer solution would surely be more affordable than some massive civil engineering.

What Will Be The Fastest Times Possible Between London King’s Cross And Leeds?

I put my thoughts in What Will Be The Fastest Times Possible Between London King’s Cross And Leeds?.

Conclusion

The original High Speed Two specification gave a time of one hour and twenty-one minutes between Euston and Leeds.

I suspect that time will be approached before 2040.

Derby Alstom Train Factory Jobs Fear As Orders Dry Up

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

This is the sub-heading.

Derby City Council is seeking talks with train builder Alstom over reports it could be about to lay off workers.

These two paragraphs introduce the story.

The firm’s Litchurch Lane site is the only UK train factory able to design, build, engineer and test trains for domestic and export markets.

About 2,000 people work at the factory but the firm says its current order book only runs until early 2024.

This could be another serious problem for High Speed Two.

Could LNER Use High Speed Two Classic-Compatible Trains?

In LNER Seeks 10 More Bi-Modes, I discuss how LNER are needing ten more bi-mode trains to expand their services.

Consider.

  • One of LNER’s predecessors used to run Eurostar trains between Kings Cross and Leeds
  • A High Speed Two Classic-Compatible trains are 200 metres long, as against the 233.7 metres of a nine-car Class 801 train.
  • High Speed Two Classic-Compatible trains will run on the East Coast Main Line, when High Speed Two fully opens.
  • London to Doncaster, Edinburgh, Leeds, Newcastle and York are all fully electrified routes.

So if all these fully-electric routes, were to be run using High Speed Two Classic-Compatible trains, this would release a number of Class 800 and Class 801 trains, which could be converted to bi-modes or battery-electric variants.

London and Edinburgh In Three-And-A-Half Hours

This is a paragraph from the Wikipedia entry for the InterCity 225 train.

The InterCity 225 was designed to achieve a peak service speed of 140 mph (225 km/h); during a test run in 1989 on Stoke Bank between Peterborough and Grantham, an InterCity 225 was recorded at a speed of 162 mph (260.7 km/h). Its high speed capabilities were again demonstrated via a 3hr 29mins non-stop run between London and Edinburgh on 26 September 1991. British regulations have since required in-cab signalling on any train running at speeds above 125 mph (201 km/h) preventing such speeds from being legally attained in regular service. Thus, except on High Speed 1, which is equipped with cab signalling, British signalling does not allow any train, including the InterCity 225, to exceed 125 mph (201 km/h) in regular service, due to the impracticality of correctly observing lineside signals at high speed.

If in-cab digital signalling were to be installed between London and Edinburgh, I believe that the three-and-a-half hour timing can be regularly achieved by a High Speed Two Classic-Compatible train.

I also believe that at least one train per hour (tph) between London and Edinburgh could achieve the three-and-a-half hour timing.

High Speed Two are promising a 3:48 time between London and Edinburgh.

It could be a Lumo-squasher!

A one tph service would need eight trains, but would release eight nine-car Class 801 trains.

Euston and Glasgow

This might be another route, where High Speed Two Classic-Compatible trains could be used.

Conclusion

LNER gets some more trains and Derby gets more work.

But the biggest benefits would be that, the trains would get a thorough testing before High Speed Two opens and passengers would get a view of the shape of things to come.

Could We See Between London And Much Of The North By Train In Under Two Hours?

I shall write about each route in order starting from Euston and working East.

Avanti West Coast And Euston

These are services from Euston, that I feel could be under two hours.

London Euston And Liverpool Lime Street

On Thursday, I went to Liverpool by train.

  • My train took two hours and thirteen minutes between London Euston and Liverpool Lime Street stations.
  • There were stops at Stafford, Crewe and Runcorn.
  • The Class 390 train was travelling at 125 mph for a lot of the way.
  • The distance between the two terminals is 193.6 miles.
  • The start to stop average including the stops was 87.3 mph.

So could London Euston and Liverpool Lime Street be achieved in the magic two hours?

A few thoughts.

Average Speed

To do the journey in this time  would need an average speed of 96.8 mph.

Accelerating And Stopping

Ideally, the train will run as fast as it can only changing speed for the station stops.

  • The train will accelerate from stop to cruising speed at Euston, Stafford, Crewe and Runcorn or four times.
  • The train will decelerate from cruising speed to stop at Stafford, Crewe, Runcorn and Liverpool Lime Street or four times.

Effectively, the train goes through four complete station stops, although one will be split between the two ends of the journey.

These figures are from Wikipedia and the Internet

  • The acceleration of the Class 390 train is 1.0 mph/sec which means that it takes 125 seconds to get to 125 mph.
  • The deceleration of a Class 390 train is 2.0 mph/sec, which means that it takes 63 seconds to stop from 125 mph.
  • The acceleration of a Class 801 train is 1.6 mph/sec which means that it takes 78 seconds to get to 125 mph.
  • The deceleration of a Class 801 train is 2.2 mph/sec, which means that it takes 57 seconds to stop from 125 mph.

These figures would appear to show, that a Class 801 train can decelerate and accelerate at a stop in nearly a minute faster than a Class 390 train.

So how can we increase the acceleration and deceleration? The two obvious ways are more power and less weight.

Form the Internet, I estimate that the average car in a Class 390 train is around 52 tonnes, as opposed to 41 tonnes for the Hitachi trains.

So does this weight difference explain some of the difference in acceleration and deceleration times?

Consider.

  • The Class 390 trains have all the extra weight of the tilt mechanism. More weight means slower acceleration.
  • Avanti West Coast’s new Class 807 trains have no diesel engines or batteries. Have the trains been put on a diet?
  • They also have a reprofiled nose. Is it more aerodynamic?

So if these trains can save time on the four accelerate/decelerate cycles compared to the Class 390 trains, they must be getting nearer to the magic two hours.

If two minutes a stop can be saved that would save eight minutes on the journey between London Euston and Liverpool Lime Street.

140 Mph Running

The time to do a mile at various speeds are as follows.

  • 100 mph – 36 seconds
  • 125 mph – 29 seconds
  • 140 mph – 26 seconds

So running at 140 mph, as opposed to the current 125 mph would save three seconds for every mile.

To save five minutes would mean the train would have to run for a hundred miles at 140 mph instead of 125 mph.

As Stafford is 133.5 miles from London, it could be that full digital signalling should be installed on the West Coast Main Line all the way to Stafford or even Crewe, which is 158 miles from London.

This schematic map of the West Coast Main Line was clipped from Wikipedia.

Note.

  1. Trains between London Euston and Liverpool Lime Street take the Trent Valley Line through Nuneaton and Lichfield Trent Valley and stop at Stafford, Crewe and Runcorn.
  2. Trains between London Euston and Manchester take a variety of routes and all go via Stockport.
  3. One train per hour (tph) between London Euston and Glasgow Central takes the Trent Valley Line and goes non-stop between London Euston and Warrington Central.
  4. Norton Bridge Junction just to the North of Stafford has recently been remodelled.

I believe there is potential to enable up to at least a hundred miles of 140 mph running to the South of Crewe. Especially as most of the track South of Crewe is quadruple track.

This should enable the shaving of five or more minutes off the time of any train capable of 140 mph running that uses the Trent Valley Line through Nuneaton, Lichfield Trent Valley and Stafford.

Norton Bridge Junction

Norton Bridge junction, which is five miles North  used to be a bottleneck, but it has now been remodelled.

I wrote about it in The New Norton Bridge Junction In Action.

The new junction has probably been designed so that it can save a few seconds for trains going between Stafford and Crewe, whether or not they stop at either or both stations.

Non-Stop Between London Euston and Runcorn

If you look at the times of a London Euston and Glasgow Central train via the Trent Valley Line , it travels the 174.7 miles between London Euston and Weaver Junction non-stop in one hour and forty minutes. This is an average speed of 104.8 mph.

By comparison, my train on Thursday took one hour and forty-seven minutes with the two stops at Stafford and Crewe.

So there is at least six minutes to be saved by going non-stop.

 

Two Trains Per Hour Between London Euston And Liverpool Lime Street

Wikipedia says this about an additional service.

Subject to approval by the Office of Rail and Road, an additional hourly service will be introduced between London Euston and Liverpool Lime Street with a stop at Liverpool South Parkway from December 2022.

I have a few thoughts and questions on extra services between London Euston and Liverpool Lime Street,

  • In my view the second service is much needed.
  • I also think, that a later train back to London is needed.
  • Does the Wikipedia statement mean that only one train will stop at Liverpool South Parkway?
  • Does Runcorn need two tph to and from London?
  • Would the platforms at Liverpool South Parkway be lengthened to accept eleven-car Class 390 trains?

I feel that if a train stopped at both Liverpool South Parkway and Runcorn, this would make a two-hour journey more difficult to achieve.

London Euston And Liverpool Lime Street In Two Hours

The new Class 807 trains will be delivered by 2022. Because of the pandemic, I’ll assume that of the ten trains on order, some, but not all, will be available by the December 2022 timetable change.

The time savings needed for a two-hour journey will come from four improvements.

  1. The increased performance of the Class 807 trains.
  2. Full digital signalling South of Crewe.
  3. The track improvements already completed like Norton Bridge Junction.
  4. Cutting out stop on the second service.

There may also be time savings to be obtained at the intermediate stops, by better working practices.

I doubt that the full digital signalling will have been installed, but all trains will be capable of 125 mph running.

Avanti West Coast probably have a good idea of the time they could achieve without digital signalling and I feel that they could be about five minutes over two hours with the Class 807 trains.

As the eleven-car Class 390 trains are too long for Liverpool South Parkway station, could we see the following service?

  • 1 tph – Class 390 train – London Euston And Liverpool Lime Street via Runcorn, Crewe and Stafford.
  • 1 tph – Class 807 train – London Euston And Liverpool Lime Street via Liverpool South Parkway.

Note.

  1. The Class 390 train would run the existing timetable in two hours and thirteen minutes.
  2. The Class 807 train would be a two-hour express service if possible.
  3. Going from three stops to one could save the express at least seven minutes, as I showed earlier by looking at train timings South of Weaver Junction.
  4. There would be time savings of at least two minutes on the express service due to the better performance of the Class 807 train.

To save the final four minutes, there would need to be at least eighty miles of 140 mph running, as each mile saves three seconds.

I am fairly certain, that London Euston and Liverpool Lime Street can be regularly achieved in two hours.

London Euston And Warrington Bank Quay

The hourly London Euston and Glasgow Central expresses seem to take one hour and forty-five minutes for the non-stop trip of 182.1 miles, which is an average speed of 104 mph.

As this service is non-stop, I believe that this service would get the maximum benefit from digital signalling and this service will only get faster, as more and more of the route allowed 140 mph-running.

I wouldn’t be surprised to see almost ten minutes lopped off this service by signalling and other improvements.

I am fairly certain, that London Euston and Warrington Bank Quay can be regularly achieved in well under two hours, by a Class 390 train.

London Euston And Wigan North Western

The hourly London Euston and Glasgow Central expresses seem to take one hour and fifty-six minutes for the single-stop trip of 193.9 miles, which is an average speed of 100.3 mph.

As this service just a single stop at Warrington Bank Quay, I believe that this service would get the maximum benefit from digital signalling and this service will only get faster, as more and more of the route allowed 140 mph-running.

As with Warrington Bank Quay, I wouldn’t be surprised to see almost ten minutes lopped off this service by signalling and other improvements.

I am fairly certain, that London Euston and Wigan North Western can be regularly achieved in comfortably under two hours, by a Class 390 train.

London Euston And Preston

The hourly London Euston and Glasgow Central expresses seem to take two hours and eleven minutes for the two -stop trip of 209 miles, which is an average speed of 95.7 mph.

As this service just stops at Warrington Bank Quay and Wigan North Western, I believe that this service would get the maximum benefit from digital signalling and this service will only get faster, as more and more of the route allowed 140 mph-running.

As with Warrington Bank Quay and Wigan North Western, I wouldn’t be surprised to see almost ten minutes lopped off this service by signalling and other improvements.

I am fairly certain, that London Euston and Preston can be regularly achieved in just under two hours, by a Class 390 train.

London Euston And Blackpool North

Avanti West Coast have indicated that their new Class 807 trains will run between London Euston and Blackpool North.

Consider.

  • I am fairly certain that a Class 390 train will be able to run between London Euston and Preston in under two hours, once digital signalling is installed South of Crewe.
  • Currently, Class 390 trains take twenty minutes between Preston and Blackpool North stations.
  • The Class 807 trains have better acceleration and deceleration and should be able to execute faster stops than the Class 390 trains.

I wonder if Avanti West Coast, Hitachi, Network Rail and Rock Rail have thought up a cunning plan to run Class 807  trains between  London Euston And Blackpool North, in under two hours.

Trains would go via the Trent Valley.

Trains might only stop at perhaps Milton Keynes Central, Warrington Bank Quay, Wigan North Western and Preston.

Trains would run at up to 140 mph using digital signalling, in as many places as possible.

Is the performance of the Class 807 trains sufficient to achieve London Euston and Blackpool North in under two hours via the Trent Valley?

London Euston And Manchester Piccadilly via Wilmslow

Consider.

  • Most trains between London Euston and Manchester Piccadilly via Wilmslow seem to take around six or seven minutes over two hours.
  • I believe that if the 158 miles between London Euston and Crewe were to be digitally signalled, then this could save up to eight minutes by allowing trains to run at 140 mph rather than the current 125 mph.

This could be enough to bring the London Euston and Manchester Piccadilly via Wilmslow below two hours.

I am not surprised at this, as the trains were built for 140 mph and because there is no digital signalling, they are limited to 125 mph, which slows the trains by six or seven minutes.

London Euston And Manchester Piccadilly via Stoke-on-Trent

Everything I said about trains between London Euston and Manchester Piccadilly via Wilmslow probably apply, except that the services via Stoke-on-Trent are a few minutes slower.

But I do feel, that this could be enough to bring the London Euston and Manchester Piccadilly via Stoke-on-Trent below two hours.

East Midlands Railway And St. Pancras

These is only one service from St. Pancras, that is not comfortably under two hours.

London St. Pancras And Sheffield

A typical service between London St. Pancras And Sheffield takes a few minutes over two hours..

  • There are two tph
  • There are stops at Leicester, Loughborough, East Midlands Parkway, Long Eaton, Derby or Chesterfield depending on the service.
  • The Class 222 trains travel at 125 mph for most of the way.
  • The distance between the two terminals is 164.7 miles.
  • The start to stop average including the stops is 81 mph.

I would suspect that East Midlands Railway’s new bi-mode Class 810 trains will be able to easily break the two-hour barrier.

  • They have four diesel engines so they can cruise at 125 mph on diesel.
  • They have electric power for South of Market Harborough.
  • Some diesel engines will be changed for batteries.

As electrification increases on the Midland Main Line, these trains will use less and less diesel.

I also suspect that digital signalling will start to creep into the route, starting from Bedford, where it is used on Thameslink.

LNER And King’s Cross

These are services from King’s Cross, that are or I feel will be under two hours.

London King’s Cross And Doncaster

A typical service between London King’s Cross And Doncaster takes around one hour and thirty-seven minutes.

  • There are four tph
  • There are stops at Stevenage, Peterborough, Grantham, Newark and Retford depending on the service.
  • The Class 80x trains travel at 125 mph for most of the way.
  • The distance between the two stations is 156 miles.
  • The start to stop average including the stops is 96.5 mph.

Digital signaling is being installed on this section of the East Coast Main Line and I suspect that this will reduce timings between London King’s Cross And Doncaster.

A simple estimate based on the maximum operating speed, indicates a time of one hour and twenty-six minutes should be possible.

But as a Control Engineer, I believe that digital signalling will lead to faster running over the Digswell Viaduct and through the flat crossing at Newark.

The timing will certainly be under one hour and thirty minutes between London King’s Cross And Doncaster.

London King’s Cross And York

A typical service between London King’s Cross And York takes around one hour and forty-eight minutes.

  • There are two tph
  • There are stops at Stevenage, Peterborough, Grantham, Newark, Retford and Doncaster depending on the service.
  • The Class 80x trains travel at 125 mph for most of the way.
  • The distance between the two stations is 188.5 miles.
  • A non-stop service takes one hour and fifty-two minutes, which is a start to stop average including the stops is 101 mph.

If my crude estimate of time savings because of digital signalling South of Doncaster can be applied, this would imply a reduction in journey time of at least eleven minutes.

London King’s Cross And Leeds

A typical service between London King’s Cross And Leeds takes around two hours and thirteen minutes.

  • There are three tph
  • There are stops at Stevenage, Peterborough, Grantham, Newark, Doncaster and Wakefield Westgate depending on the service.
  • The Class 80x trains travel at 125 mph for most of the way.
  • The distance between the two terminals is 185.9 miles.
  • This is a start to stop average including the stops is 83.9 mph.

If my crude estimate of time savings because of digital signalling South of Doncaster can be applied, this would imply a reduction in journey time of at least eleven minutes, which would put a time between London King’s Cross and Leeds of around two hours.

London King’s Cross And Bradford Forster Square

LNER run some services on this route

  • The services take thirty minutes between Leeds and Bradford Forster Square stations.
  • The services do not reverse at Leeds.

Given that two hours should be possible between London Kings Cross and Leeds, it would appear that two hours and thirty minutes should be possible between Leeds and Bradford Forster Square stations.

London King’s Cross And Bradford Interchange

Grand Central run some services on this route

  • The services call at Doncaster, Wakefield Kirkgate, Mirfield, Brighouse and Low Moor
  • The services take two hours and fifty-four minutes between London King’s Cross and Bradford Interchange stations.
  • The services take one hour and seventeen minutes between Doncaster and Bradford Interchange stations.

The services are run by Class 180 diesel trains, which will have to be replaced to decarbonise the route.

I suspect that Hitachi will have a train for this route, that could use diesel or batteries to the North of Doncaster.

  • My estimate for the best time between King’s Cross and Doncaster is one hour and twenty-six minutes.
  • The current time between Doncaster and Bradford Interchange stations is one hour and seventeen minutes.

This gives a best time of perhaps two hours and forty-three minutes between Doncaster and Bradford Interchange stations.

The route to Bradford via Leeds is perhaps fifteen minutes faster, but it serves different stations.

London King’s Cross And Harrogate

LNER has been running to Harrogate for some time.

  • There is one train per two hours (tp2h)
  • The service calls at Stevenage, Grantham, Doncaster, Wakefield Westgate and Leeds.
  • some services reverse at Leeds.
  • The service takes two hours and fifty-five minutes between London King’s Cross and Harrogate stations.
  • The service takes thirty minutes between Leeds and Harrogate stations.

Given that two hours should be possible between London Kings Cross and Leeds, it would appear that two hours and thirty minutes could be possible between London King’s Cross and Harrogate stations.

London King’s Cross And Huddersfield

In LNER Expands To Huddersfield, I described LNER’s new service to Huddersfield.

  • There will be one train per day (tpd)
  • The service will call at Peterborough, Newark North Gate, Doncaster, Wakefield Westgate, Leeds and Dewsbury.
  • The service will split and join with the London King’s Cross and Skipton service at Leeds.
  • The service will reverse at Leeds.
  • The service take two hours and fifty-five minutes between London King’s Cross and Huddersfield stations.
  • The service will take twenty-five minutes between Leeds and Huddersfield stations.
  • Improvements are planned, which include electrification, between Dewsbury and Huddersfield

Given that two hours should be possible between London Kings Cross and Leeds, it would appear that two hours and thirty minutes could be possible between London King’s Cross and Huddersfield stations.

London King’s Cross And Hull

The fastest Hull Trains service between London King’s Cross And Hull takes around two hours and thirty minutes.

  • There are seven tpd
  • There are stops at Stevenage, Grantham, Retford, Doncaster, Selby, Howden and Brough depending on the service.
  • The Class 80x trains travel at 125 mph for most of the way.
  • The distance between the two terminals is 205.3 miles.
  • This is a start to stop average including the stops is 82.1 mph.

If my crude estimate of time savings because of digital signalling South of Doncaster can be applied, this would imply a reduction in journey time of at least eleven minutes, which would put a time between London King’s Cross and Hull of around two hours and twenty minutes.

London King’s Cross And Middlesbrough

LNER have announced a Middlesbrough service, which I wrote about in LNER’s Middlesbrough And London Service. Starts On December 13th.

  • There will be one tpd in both directions
  • Intermediate stops will be at Thornaby and York.
  • The Middlesbrough and London service will leave Middlesbrough from Platform 1 at 07:08 and arrive in King’s Cross at 10:22.
  • The London and Middlesbrough service will leave King’s Cross at 15:25 and arrive in Middlesbrough in Platform 2 at 18:18.

There appear to be some curiosities in the timetabling of these trains, which I may explore later.

I would assume that is because LNER want a competitive time of three hours between King’s Cross and Middlesbrough.

These are Southbound times between Eaglescliffe and King’s Cross in the morning.

  • Grand Central –  Two hours and thirty-nine minutes
  • LNER – Three hours and two minutes

Is this because the Class 180 train is a genuine 125 mph train on diesel and the Class 800 train is not?

If my crude estimate of time savings because of digital signalling South of Doncaster can be applied, this would imply a reduction in journey time of at least eleven minutes, which would put a time between London King’s Cross and Middlesbrough of around three hours.

Conclusion

Of the cities and towns in the North, that I have discussed only Bradford, Harrogate, Huddersfield, Hull and Middlesbrough, are ones that will be difficult to be provided with a two-hour journey time to and from London. But all should be possible in close to or under two hours and thirty minutes.

The London And Edinburgh Travel Market

This paragraph comes from of this article on Railway Gazette.

Lumo is aiming to carry more than 1 million passengers per year. It is particularly targeting people who currently fly between Edinburgh and London; in June it says there were 74 764 air journeys on the route, compared to 82 002 by rail.

Lumo’s million passengers per year, will equate to around 83,300 passengers per month.

What these figures don’t show is the number of rail journeys made to intermediate stations like Newcastle, York, Doncaster and Peterborough.

These are a few thoughts.

Rail Capacity Between London And Edinburgh

Consider.

  • LNER is currently the only rail carrier offering a daytime service between London and Edinburgh.
  • LNER run approximately 26 trains per day (tpd) in both directions between London and Edinburgh.
  • A nine-car Class 801 train can carry 510 Standard Class passengers and 101 First Class passengers.

That means that LNER had a capacity of just over 950,000 seats in June.

It might seem poor to have only sold 82,002 seats in June between London and Edinburgh, which is just 8.6 % of the available seats.

On the other hand, LNER’s two trains per hour (tph) are a lot more than London and Edinburgh trains, as they connect towns and cities all the way up the East Coast Main Line between London and Aberdeen.

Lumo’s capacity of a million seats per year, works out at 83,300 seats per month, which is another 8.7 % of capacity.

  • Lumo will sell seats on price initially and I suspect they’ll end up running about 85-95 % full.
  • It has been stated that they need to run 80% full to break even.
  • I also think, that they would like to have a few seats for late bookers.

But even so, they will surely affect LNER’s bookings.

What Will LNER Do?

Several of the things, that Lumo are doing can be easily copied by LNER.

  • Early booking.
  • Improve onboard service.
  • Better seating.

They could even reduce prices.

I think it is very likely we could end up with a price and service war between LNER and Lumo.

Would The Airlines Be The Losers?

This could be an outcome of competition between LNER and Lumo.

We are now talking about times of around four hours and twenty-five minutes between London and Edinburgh, but there are improvements underway on the East Coast Main Line.

  • The remodelling of the approach to Kings Cross station has not been reflected in the timetables.
  • The Werrington Dive Under has not been completed yet.
  • Digital signalling is being installed South of Doncaster.
  • The power supply is being upgraded North of Newcastle.

When these and other improvements are complete, I can see journey times reduced below four hours.

But would that only be for starters?great b

If a 1970s-technology Intercity 225 train, admittedly running as a shortened train formation, could achieve a time of just under three-and-a-half hours for the 393.2 miles between Kings Cross and Edinburgh stations in September 1991, what could a modern Hitachi train do, if all of the improvements had been completed and perhaps half of the route could be run at 140 mph under the watchful eyes of full digital signalling and an experienced driver.

Consider.

  • London and York is nearly two hundred miles of fairly straight railway, that is ideal for high speed.
  • Current trains run the 393.2 miles in four hours 25 minutes, which is an average speed of 89 mph.
  • A train running at 89 mph would take two hours and fifteen minutes to cover 200 miles.
  • A train running at 125 mph would take one hour and thirty-six minutes to cover 200 miles.
  • A train running at 140 mph would take one hour and twenty-six minutes to cover 200 miles.

When Network Rail, Great British Railways or the Prime Minister renames the East Coast Main Line as High Speed East Coast, I think we can be sure that trains between London and Edinburgh will be able to achieve three-and-a-half hours between the two capitals.

High Speed Two is only promising three hours and forty-eight minutes.

What About LNER’s New Trains?

LNER Seeks 10 More Bi-Modes, was written to explore the possibilities suggested by a short article in the December 2020 Edition of Modern Railways.

There has been no sign of any order being placed, but Hitachi have moved on.

  • They are building the prototype of the Hitachi Intercity Tri-Mode Battery for testing on the Great Western Railway.
  • They have completed some of the Class 803 trains for East Coast Trains, which has now been renamed Lumo. These trains have a battery for hotel power in case of catenary failure, but no diesel engines.
  • They are building the Class 807 trains for Avanti West Coast, which appear to be designed for high speed and have no batteries or diesel engines.
  • The latest versions of the trains will have a reshaped nose. Is it more aerodynamic at high speeds?

It does seem that there is an emphasis on speed, better acceleration and efficiency.

  • Could the lessons learned be used to improve the performance of the existing trains?
  • Could a small high performance sub-fleet be created to run LNER’s Scottish services?

There are certainly possibilities, that would cut journey times between London and Edinburgh.

Conclusion

I can see the airlines flying between London and Edinburgh suffering a lot of collateral damage, as the two train companies slug it out.

Approaching Kings Cross – 5th July 2021

I took these pictures approaching Kings Cross.

Reports say most of the work of the remodelling is now complete. Although, it did look to me that in places more tracks could be laid.

The Length Of The Long Platforms At Kings Cross

This repeat of the last picture in the gallery shows the length of the nine long platforms.

Note.

  1. The train is in Platform 3.
  2. The train is an eight-car Class 700 train.
  3. Eight-car units are 162 metres long.
  4. Twelve-car units are 242.6 metres long.

Platform 3 is obviously long enough to take the following trains.

This Google Map shows the ends of the platforms at Kings Cross.

Note.

  1. The long platforms at the right are 2 and 3.
  2. Platform 2 and 3 are wide.
  3. Two LNER Azumas are in Platforms 5 and 6.

It looks to me that whilst all platforms can probably handle the standard British Rail length of 240 metres, those on the right may be able to handle longer trains. But what trains? These are my thoughts.

Longer LNER Azumas

This document on the Hitachi Rail web site is entitled Development of Class 800/801 High-speed Rolling Stock for UK Intercity Express Programme.

The document says that Class 80x trains have a sophisticated Train Control and Management System (TCMS).

The document says that this is one of the functions of the TCMS.

To simplify the rearrangement and management of train configurations, functions are provided for
identifying the train (Class 800/801), for automatically determining the cars in the trainset and its total length,
and for coupling and uncoupling up to 12 cars in normal and 24 cars in rescue or emergency mode.

I would assume that with the purchase of extra cars, that it might be possible to lengthen trains to up to twelve cars.

Lengths would be as follows.

  • Ten-car Class 80x train – 260 metres.
  • Eleven-car Class 80x train – 276 metres.
  • Twelve-car Class 80x train – 312 metres.

To add extra capacity on the routes to Leeds and Edinburgh services, there must be a balance between these factors.

  • The cost of extra cars.
  • The cost of platform lengthening.

There must of course be space for any platform lengthening.

It would seem to me, that common sense should allow twelve-car trains to be handled at King’s Cross, as this must be one of the best ways of adding capacity to East Coast Main Line services.

Caledonian Sleeper

The Caledonian Sleeper doesn’t normally run into King’s Cross, but during the rebuilding Euston for High Speed Two, it may be necessary to provide an alternative platform.

Unfortunately, the sixteen-car Caledonian sleeper trains are 352 metres long. So it would appear that Kings Cross would not be a temporary alternative.

But given the amount of money being invested in sleeper trains in Europe by the likes of Midnight Trains and NightJet, I can see that the Caledonian Sleeper might have another problem – success and the need for more capacity.

So I wouldn’t rule out an East Coast Main Line sleeper train between London Kings Cross and Edinburgh.

It might call at Stevenage, Newcastle and Berwick to widen its passenger base, just as the current sleeper calls at Watford, Carlisle and Carstairs.

The train could be extended to Aberdeen, to simplify services in Scotland.

Obviously, traffic and finance would decide, but I wouldn’t rule out the Caledonian Sleeper running to and from King’s Cross for a few years yet.

A Night Light Freight Terminal

In Is This The Shape Of Freight To Come?, I wrote about the new generation of fast electric freight trains, based on redundant electric multiple units.

  • If you look at Real Time Trains, you will find that few trains use King’s Cross station between two and five in the morning.
  • Platforms can take a twelve-car version of these electric freight trains.
  • The new platforms are wide and level.
  • Local delivery could use electric vehicles and bikes.

I think King’s Cross has possibilities for handling goods like food, parcels and shop supplies.

The Short Platforms At Kings Cross

When I was a child, King’s Cross had four short suburban platforms, where N2 steam tank engines hauled suburban services in and out of the station.

The suburban platforms have now been reduced to two platforms, that fit in with the current uses of the station.

  • The two platforms are numbered 9 and 10.
  • They can handle an eight-car Class 700 train, which is 162 metres long.
  • They can handle a five-car Class 800 train, which is 130 metres long.
  • Some five-car services run by the new Hitachi trains use these platforms.

These pictures show the platforms.

Note.

  1. The platforms are wide.
  2. The picture of the Azuma in Platform 9 was taken before the centre track was removed recently.
  3. Today, one LNER Azuma departed from Platform 9 to go to Lincoln, but both platforms were busy with Great Northern services to Cambridge, Ely and Kings Lynn.

I do wonder if the platforms could be used for light freight, during the night.

Conclusion

King’s Cross is not just one of the UK’s finest railway stations, which is recognised by its Grade I Listed status, but it is now moving towards an efficient, high-capacity station that works around the clock!

Thoughts On Batteries On A Hitachi Intercity Tri-Mode Battery Train

This Hitachi infographic describes a Hitachi Intercity Tri-Mode Battery Train.

Hitachi are creating the first of these battery trains, by replacing one of the diesel power-packs in a Class 802 train with a battery-pack from Hyperdrive Innovation of Sunderland.

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%, gives a few more details.

The Class 802 train has the following characteristics.

  • Five cars.
  • Three diesel power-packs, each with a power output of 700 kW.
  • 125 mph top speed on electricity.
  • I believe all intermediate cars are wired for diesel power-packs, so can all intermediate cars have a battery?

In How Much Power Is Needed To Run A Train At 125 Or 100 mph?, I estimated that the trains need the following amounts of energy to keep them at a constant speed.

  • Class 801 train – 125 mph 3.42 kWh per vehicle mile
  • Class 801 train – 100 mph 2.19 kWh per vehicle mile

The figures are my best estimates.

The Wikipedia entry for the Class 800 train, also gives the weight of the diesel power-pack and all its related gubbins.

The axle load of the train is given as 15 tonnes, but for a car without a diesel engine it is given as 13 tonnes.

As there are four axles to a car, I can deduce that the diesel power-pack and the gubbins, weigh around eight tonnes.

How much power would a one tonne battery hold?

This page on the Clean Energy institute at the University of Washington is entitled Lithium-Ion Battery.

This is a sentence from the page.

Compared to the other high-quality rechargeable battery technologies (nickel-cadmium or nickel-metal-hydride), Li-ion batteries have a number of advantages. They have one of the highest energy densities of any battery technology today (100-265 Wh/kg or 250-670 Wh/L).

Using these figures, a one-tonne battery would be between 100 and 265 kWh in capacity, depending on the energy density.

As it is likely that if the diesel power-pack replacement would probably leave things like fuel tanks and radiators behind, so that the diesel engines could be reinstalled, I would expect that a battery of around four tonnes would be fitted.

On the basis of the University of Washington’s figures a 400 kWh battery pack would certainly be feasible.

Using. the energy use at 100 mph of 2.19 kWh per vehicle mile, I can get the following ranges for different battery sizes.

  • 400 kWh battery – 36.53 miles
  • 500 kWh battery – 45.67 miles
  • 600 kWh battery – 54.80 miles
  • 800 kWh battery – 73.06 miles

As Lincoln and Newark are just 16.6 miles apart, it looks to me that a 500 or 600 kWh battery could be a good choice for that route, as it would leave enough hotel power for the turnround.

It should also handle shorter routes like these.

  • Newbury and Bedwyn – 13.3 miles.
  • Didcot and Oxford – 10.3 miles
  • Newark and Lincoln – 16.6 miles
  • Leeds and Harrogate – 18.3 miles
  • Northallerton and Middlesbrough – 20 miles
  • Hull and Temple Hirst Junction and Hull – 36.1 miles

Some routes like Temple Hirst Junction and Hull would need charging at the destination.

The Range Of A Five Car Train With Three Batteries

Suppose a Hitachi Intercity Tri-Mode Battery Train had three battery-packs and no diesel engines.

  • It would be based on Hitachi Intercity Tri-Mode Battery Train technology.
  • It would have two driver cars without batteries.
  • It would have three intermediate cars with 600 kWh batteries.
  • It would have 1800 kWh in the batteries.
  • The train would be optimised for 100 mph running.
  • My estimate says it would need 2.19 kWh per vehicle mile to cruise at 100 mph.

It could have a range of up to 164 miles.

If the batteries were only 500 kWh, the range would be 137 miles.

The Ultimate Battery Train

I think it would be possible to put together a nine car battery-electric train with a long range.

  • It would be based based on Hitachi Intercity Tri-Mode Battery Train technology, which would be applied to a Class 800 or Class 802 train.
  • It would have two driver cars without batteries.
  • It would have seven intermediate cars with 600 kWh batteries.
  • It would have a total battery capacity of 4200 kWh.
  • The train would be optimised for 100 mph running.
  • My estimate in How Much Power Is Needed To Run A Train At 125 Or 100 mph?, said it would need 2.19 kWh per vehicle mile to cruise at 100 mph.

That would give a range of over 200 miles.

If the batteries were only 500 kWh, the range would be 178 miles.

Aberdeen, Inverness, Penzance and Swansea here we come.

Can Hitachi Increase The Range Further?

There are various ways that the range can be improved.

  • More electrically-efficient on-board systems like air-conditioning.
  • A more aerodynamic nose.
  • Regenerative braking to the batteries.
  • Batteries with a higher energy density.
  • Better driver assistance software.

Note.

  1. Hitachi have already announced that the Class 810 trains for East Midlands Railway will have a new nose profile.
  2. Batteries are improving all the time.

I wouldn’t be surprised to see a ten percent improvement in range by 2030.

Conclusion

I was surprised at some of the results of my estimates.

But I do feel that Hitachi trains with 500-600 kWh batteries could bring a revolution to train travel in the UK.

Edinburgh And Aberdeen

Consider.

  • The gap in the electrification is 130 miles between Edinburgh Haymarket and Aberdeen.
  • There could be an intermediate charging station at Dundee.
  • Charging would be needed at Aberdeen.

I think Hitachi could design a train for this route.

Edinburgh And Inverness

Consider.

  • The gap in the electrification is 146 miles between Stirling and Inverness.
  • This could be shortened by 33 miles, if there were electrification between Stirling and Perth.
  • Charging would be needed at Inverness.

I think Hitachi could design a train for this route.

What Is Possible On The East Coast Main Line?

In the Wikipedia entry for the Class 91 locomotive, there is an amazing story.

This picture shows one of these locomotives at Kings Cross.

Note.

  1. They have a design speed of 140 mph.
  2. They have a power output of 4.8 MW.
  3. They were built around 1990 by British Rail at Crewe.

They were designed to run services between London King’s Cross and Edinburgh as fast as possible, as the motive power of the InterCity 225 trains.

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.

Note.

  1. For the British locomotive speed record, locomotive was actually pushing the train and going backwards, as the driving van trailer (DVT) was leading.
  2. How many speed records of any sort, where the direction isn’t part of the record, have been set going backwards?
  3. I feel that this record could stand for many years, as it is not very likely anybody will build another 140 mph locomotive in the foreseeable future. Unless a maverick idea for a high speed freight locomotive is proposed.

I have a few general thoughts on the record run between Kings Cross and Edinburgh in three-and-a-half hours.

  • I would assume that as in normal operation of these trains, the Class 91 locomotive was leading on the run to the North.
  • For various reasons, they would surely have had at least two of British Rail’s most experienced drivers in the cab.
  • At that time, 125 mph InterCity 125 trains had been the workhorse of East Coast Main Line for well over ten years, so British Rail wouldn’t have been short of experienced high speed drivers.
  • It was a Thursday, so they must have been running amongst normal traffic.
  • On Monday, a typical run between Kings Cross and Edinburgh is timetabled to take four hours and twenty minutes.
  • High Speed Two are predicting a time of three hours and forty-eight minutes between Euston and Edinburgh via High Speed Two and  the West Coast Main Line.

The more you look at it, a sub-three-and-and-a-half hour time, by 1980s-technology on a less-than-perfect railway was truly remarkable.

So how did they do it?

Superb Timetabling

In Norwich-In-Ninety Is A Lot More Than Passengers Think!, I talk about how Network Rail and Greater Anglia created a fast service between Liverpool Street and Norwich.

I suspect that British Rail put their best timetablers on the project, so that the test train could speed through unhindered.

Just as they did for Norwich-in-Ninety and probably will be doing to the East Coast Main Line to increase services and decrease journey times.

A Good As ERTMS Signalling

Obviously in 1991, there was no modern digital in-cab signalling and I don’t know the standard of communication between the drivers and the signallers.

On the tricky sections like Digswell Viaduct, through Hitchin and the Newark Crossing were other trains stopped well clear of any difficult area, as modern digital signalling can anticipate and take action?

I would expect the test train got a signalling service as good as any modern train, even if parts of it like driver to signaller communication may have been a bit experimental.

There may even have been a back-up driver in the cab with the latest mobile phone.

It must have been about 1991, when I did a pre-arranged airways join in my Cessna 340 on the ground at Ipswich Airport before take-off on a direct flight to Rome. Air Traffic Control had suggested it to avoid an intermediate stop at say Southend.

The technology was arriving and did it help the drivers on that memorable run North ensure a safe and fast passage of the train?

It would be interesting to know, what other equipment was being tested by this test train.

A Possible Plan

I suspect that the plan in 1991 was to use a plan not unlike one that would be used by Lewis Hamilton, or in those days Stirling Moss to win a race.

Drive a steady race not taking any chances and where the track allows speed up.

So did British Rail drive a steady 125 mph sticking to the standard timetable between Kings Cross and Edinburgh?

Then as the Wikipedia extract indicated, at several times during the journey did they increase the speed of the train to 140 mph.

And the rest as they say was an historic time of 3 hours, 29 minutes and 30 seconds. Call it three-and-a-half-hours.

This represented a start-to-stop average speed of 112.5 mph over the 393 miles of the East Coast Main Line.

Can The Current Trains Achieve Three-And-A-Half-Hours Be Possible Today?

Consider.

  • The best four hours and twenty minutes timings of the Class 801 trains, represents an average speed of 90.7 mph.
  • The Class 801 trains and the InterCity 225 trains have similar performance.
  • There have been improvements to the route like the Hitchin Flyover.
  • Full ERTMS in-cab signalling is being installed South of Doncaster.
  • I believe ERTMS and ETC could solve the Newark Crossing problem! See Could ERTMS And ETCS Solve The Newark Crossing Problem?
  • I am a trained Control Engineer and I believe if ERTMS and ETC can solve the Newark Crossing problem, I suspect they can solve the Digswell Viaduct problem.
  • The Werrington Dive Under is being built.
  • The approaches to Kings Cross are being remodelled.

I can’t quite say easy-peasy. but I’m fairly certain the Kings Cross and Edinburgh record is under serious threat.

  • A massive power supply upgrade to the North of Doncaster is continuing. See this page on the Network Rail web site.
  • ERTMS and ETC probably needs to be installed all the way between Kings Cross and Edinburgh.
  • There may be a need to minimise the number of slower passenger trains on the East Coast Main Line.
  • The Northumberland Line and the Leamside Line may be needed to take some trains from the East Coast Main Line.

Recent Developments Concerning the Hitachi Trains

There have been several developments  since the Hitachi Class 800 and Class 801 trains were ordered.

  • Serious engineers and commentators like Roger Ford of Modern Railways have criticised the lugging of heavy diesel engines around the country.
  • Network Rail have upgraded the power supply South of Doncaster and have recently started to upgrade it between Doncaster and Edinburgh. Will this extensive upgrade cut the need to use the diesel power-packs?
  • Hitachi and their operators must have collected extensive in-service statistics about the detailed performance of the trains and the use of the diesel power-packs.
  • Hitachi have signed an agreement with Hyperdrive Innovation of Sunderland to produce battery-packs for the trains and two new versions of the trains have been announced; a Regional Battery Train and an Intercity Tri-Mode Battery Train.
  • East Coast Trains have ordered five five-car Class 803 trains, each of which will have a small battery for emergency use and no diesel power-packs.
  • Avanti West Coast have ordered ten seven-car Class 807 trains, each of which have no battery or diesel power-packs.

And these are just the ones we know about.

The Class 807 Trains And Liverpool

I find Avanti West Coast’s Class 807 trains the most interesting development.

  • They have been partly financed by Rock Rail, who seem to organise train finance, so that the train operator, the train manufacturer all get the best value, by finding good technical solutions.
  • I believe that these trains have been designed so they can run between Euston and Liverpool Lime Street stations in under two hours.
  • Does the absence of battery or diesel power-packs save weight and improve performance?
  • Euston and Liverpool Lime Street in two hours would be an average of only 96.8 mph.
  • If the Class 807 trains could achieve the same start-stop average of 112.5 mph achieved by the InterCity 225 test run between Kings Cross and Edinburgh, that would mean a Euston and Liverpool Lime Street time of one hour and forty-three minutes.
  • Does Thunderbird provision on the West Coast Main Line for the Class 390 trains mean that the Class 807 trains don’t need emergency power?
  • Have diesel power-packs been rarely used in emergency by the Hitachi trains?

I believe the mathematics show that excellent sub-two hour times between Euston and Liverpool Lime Street are possible by Avanti West Coast’s new Class 807 trains.

The Class 803 Trains And Edinburgh

East Coast Trains ordered their Class 803 trains in March 2019,  nine months before Avanti West Coast ordered their Class 807 trains.

In Trains Ordered For 2021 Launch Of ‘High-Quality, Low Fare’ London – Edinburgh Service, I outlined brief details of the trains and the proposed service.

  • FirstGroup is targeting the two-thirds of passengers, who fly between London and Edinburgh.
  • They are also targeting business passengers, as the first train arrives in Edinburgh at 10:00.
  • The trains are five-cars.
  • The trains are one class with onboard catering, air-conditioning, power sockets and free wi-fi.
  • Stops will be five trains per day with stops at Stevenage, Newcastle and Morpeth.
  • The trains will take around four hours.
  • The service will start in Autumn 2021.

I also thought it would be a successful service

As I know Edinburgh, Liverpool and London well, I believe there are similarities between the Euston-Liverpool Lime Street and Kings Cross-Edinburgh routes.

  • Both routes are between two cities known all over the world.
  • Both routes are fully-electrified.
  • Both routes have the potential to attract passengers from other transport modes.

The two services could even be run at similar speeds.

  • Euston-Liverpool Lime Street in two hours will be at 96.8 mph
  • Kings Cross-Edinburgh in four hours will be at 98.3 mph.

Does this explain the similar lightweight trains?

Could Lightweight Trains Help LNER?

There is one important factor, I haven’t talked about in detail in this post. Batteries and diesel power-packs on the Hitachi trains.

I have only mentioned them in the following circumstances.

  • When trains are not fitted with battery and/or diesel power-packs.
  • When battery developments are being undertaken.

Let’s consider the LNER fleet.

  • LNER has thirteen nine-car Class 800 trains, each of which has five diesel power-packs
  • LNER has ten five-car Class 800 trains, each of which has three diesel power-packs
  • LNER has thirty nine-car Class 801 trains, each of which has one diesel power-pack
  • LNER has twelve five-car Class 801 trains, each of which has one diesel power-pack

There are sixty-five trains, 497 coaches and 137 diesel power-packs.

And look at their destinations.

  • Aberdeen – No Electrification from Edinburgh
  • Alnmouth – Fully Electrified
  • Berwick-upon-Tweed – Fully Electrified
  • Bradford Forster Square – Fully Electrified
  • Darlington – Fully Electrified
  • Doncaster – Fully Electrified
  • Durham – Fully Electrified
  • Edinburgh – Fully Electrified
  • Glasgow – Fully Electrified
  • Grantham – Fully Electrified
  • Harrogate – No Electrification from Leeds – Possible Battery Destination
  • Huddersfield – No Electrification from Leeds – Possible Battery Destination – Probable Electrification
  • Hull – No Electrification from Temple Hirst Junction – Possible Battery Destination
  • Inverness – No Electrification from Stirling
  • Leeds – Fully Electrified
  • Lincoln – No Electrification from Newark North Gate – Possible Battery Destination
  • Middlesbrough – No Electrification from Northallerton – Possible Battery Destination
  • Newcastle – Fully Electrified
  • Newark North Gate – Fully Electrified
  • Northallerton – Fully Electrified
  • Peterborough – Fully Electrified
  • Skipton – Fully Electrified
  • Retford – Fully Electrified
  • Stevenage – Fully Electrified
  • Stirling – Fully Electrified
  • Sunderland – No Electrification from Northallerton – Possible Battery Destination
  • Wakefield Westgate – Fully Electrified
  • York – Fully Electrified

The destinations can be summarised as followed.

  • Not Electrified – 2
  • Possible Battery Destination – 6
  • Fully Electrified – 20

This gives a total of 28.

Could the trains be matched better to the destinations?

  • Some routes like Edinburgh, Glasgow, Newcastle and Stirling could possibly be beneficially handled by lightweight trains without any diesel or battery power-packs.
  • Only Aberdeen and Inverness can’t be reached by all-electric or battery-electric trains.
  • In LNER Seeks 10 More Bi-Modes, I proposed a hydrogen-electric flagship train, that would use hydrogen North of the existing electrification.

There certainly appear to be possibilities.

Example Journey Times To Edinburgh

This table shows the various time for particular start-stop average speeds between Kings Cross and Edinburgh.

  • 80 mph – 4:54
  • 85 mph – 4:37
  • 90 mph – 4:12
  • 98.2 mph – 4:00
  • 100 mph – 3:56
  • 110 mph – 3:34
  • 120 mph – 3:16
  • 125 mph – 3:08

Note.

  • Times are given in h:mm.
  • A few mph increase in average speed reduces journey time by a considerable amount.

The figures certainly show the value of high speed trains and of removing bottlenecks, as average speed is so important.

Decarbonisation Of LNER

LNER Seeks 10 More Bi-Modes was based on an article in the December 2020 Edition of Modern Railways, with the same title. These are the first two paragraphs of the article.

LNER has launched the procurement of at least 10 new trains to supplement its Azuma fleet on East Coast main line services.

In a Prior Information Notice published on 27 October, the operator states it is seeking trains capable of operating under 25kW overhead power with ‘significant self-power capability’ for operation away from overhead wires. ‘On-board Energy Storage for traction will be specified as a mandatory requirement to reduce, and wherever practical eliminate, diesel usage where it would otherwise be necessary, although LNER anticipates some degree of diesel traction may be required to meet some self-power requirements. Suppliers tendering are asked to detail their experience of designing and manufacturing a fleet of multi-mode trains with a range of traction options including battery-electric, diesel-electric, hydrogen-electric, battery-diesel, dual fuel and tri-mode.

From this, LNER would appear to be serious about decarbonisation and from the destination list I published earlier, most services South of the Scottish Central Belt can be decarbonised by replacing diesel-power packs with battery power-packs.

That last bit, sounds like a call for innovation to provide a solution to the difficult routes to Aberdeen and Inverness. It also looks as if it has been carefully worded not to rule anybody out.

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%.

It announces the Hitachi Intercity Tri-mode Battery Train, which is described in this Hitachi infographic.

As the Hitachi press release is dated the 15th of December 2020, which is after the publication of the magazine, it strikes me that LNER and Hitachi had been talking.

At no point have Hitachi stated what the range of the train is on battery power.

To serve the North of Scotland these gaps must be bridged.

  • Aberdeen and Edinburgh Haymarket – 130 miles
  • Inverness and Stirling – 146 miles

It should also be noted that distances in Scotland are such, that if these gaps could be bridged by battery technology, then probably all of the North of Scotland’s railways could be decarbonised. As Hitachi are the major supplier of Scotland’s local and regional electric trains, was the original Prior Information Notice, written to make sure Hitachi responded?

LNER run nine-car Class 800 trains on the two long routes to Aberdeen and Inverness.

  • These trains have five diesel power-packs under coaches 2,3, 5, 7 and 8.
  • As five-car Class 800 trains have diesel power-packs under coaches 2, 3 and 4, does this mean that Hitachi can fit diesel power-packs under all cars except for the driver cars?
  • As the diesel and battery power-packs appear to be interchangeable, does this mean that Hitachi could theoretically build some very unusual trains?
  • Hitachi’s trains can be up to twelve-cars in normal mode and twenty-four cars in rescue mode.
  • LNER would probably prefer an all Azuma fleet, even if a few trains were a bit longer.

Imagine a ten-car train with two driver and eight intermediate cars, with all of the intermediate cars having maximum-size battery-packs.

Supposing, one or two of the battery power-packs were to be replaced with a diesel power-pack.

There are a lot of possibilities and I suspect LNER, Hitachi and Hyperdrive Innovation are working on a train capable of running to and from the North of Scotland.

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?
