The Anonymous Widower

Bombardier And Hitachi Come Up With Similar Car Lengths

In an article in the October 2019 Edition of Modern Railways, which is entitled EMR Kicks Off New Era, more details of the new Hitachi bi-mode trains for East Midlands Railway are given.

This is said.

The first train is required to be available for testing in December 2021 with service entry between April and December 2022.

The EMR bi-modes will be able to run at 125 mph in diesel mode, matching Meridian performance in a step-up from the capabilities of the existing Class 80x units in service with other franchises. They will have 24 metre vehicles (rather than 26 metres), a slightly different nose to the ‘800s’ and ‘802s’, and will have four diesel engines rather than three.

I will examine this extract further.

Car Length

If you look at Bombardier’s Class 720 train, the five-car trains are 122 metres long, giving a 24 metre car length.

The ten car Class 720 train is 243 metres long, which is a similar length to three Class 360 trains running as a twelve-car train and only a few metres longer than three Class 321 trains running together.

This must be good for Greater Anglia’s train renewal, as it will minimise expensive platform lengthening.

It looks to me, that two of the new EMR InterCity trains running as a pair will be of a similar length to a twelve-car formation of Class 360 trains.

Consider.

  • As trains for EMR InterCity and EMR Electrics will share platforms at some stations, platform lengthening will again be minimised.
  • If you divide 240 by 10, you usually get the same answer of 24.
  • But if 26 metre cars were to be used, a nine-car EMR bi-mode would be 234 meres long. and two five-car trains working together would be 260 metres long.
  • Twelve-car Class 700 trains are 242.6 metres long.

These points lead me to believe that 24 metre cars are a better length for the Hitachi trains as ten-car formations are the same length as twelve-car formations of many of the UK’s older multiple units.

Maximum Speed On Diesel

Consider.

  • Various places on the Internet say that the maximum speed on diesel of a Class 800 train is 118 mph.
  • Maximum speed of a train is probably more determined by the aerodynamic drag of the train, which is proportional to the square of the speed.
  • So if a Class 800 train needs 3 * 560 kW to maintain 118 mph, it will need 1885 kW or 12.2 percent more power to maintain 125 mph
  • A fourth 560 kW diesel engine will add 33.3 percent more power.

This rough calculation shows that a fourth engine will allow the train to more than  attain and hold 125 mph on the same track where a Class 800 train can hold 118 mph.

But adding a fourth engine is a bit of a crude solution.

  • It will add more dead weight to the train.
  • It will be useful when accelerating the train, but probably not necessary.
  • It will add more noise under the train. Especially, if four cars had engines underneath.
  • It could cause overheating problems, which have been reported on the current trains.

I’ll return to this later.

Aerodynamics

Power required to maintain 125 mph can be reduced in another much more subtle way; by improving the aerodynamics.

  • I have stood on a platform, as an Aventra has silently passed at speed. It is very quiet, indicating that the aerodynamics are good.
  • But then Bombardier are an aerospace company as well as a train builder.

I’ve no idea if a Bombardier Class 720 train has less aerodynamic drag, than a Hitachi Class 800 train, but I’m sure that aerodynamic wizards from Formula One could improve the aerodynamics of the average modern train.

Could better aerodynamics explain why the EMR InterCity bi-modes are stated to have a different nose?

Look at the noses on these Spanish High Speed trains, which were built by Talgo!

Are they more aerodynamic? Do they exert a higher down-force making the train more stable?

They certainly are different and they obviously work., as these are very fast trains.

Incidentally, these trains, are nicknamed pato in Spanish, which means duck in English.

Aerodynamic drag is proportional to a drag coefficient for the object and the square of the speed.

Let’s assume the following.

  • The drag coefficient for the current train is d.
  • The drag coefficient for the train with the aerodynamic nose is a.
  • The terminal velocity of the train with the aerodynamic nose is v.

If the current Class 800 train travels at 118 mph on full power of 1680 kW, what speed would the train with an improved aerodynamic nose do on the same power, for various values of a?

If the new nose gives a five percent reduction in aerodynamic drag, then a = 0.95 * d, then the maximum speed of the train will be given by this formula

d * 118 * 118 = .0.95 * d * v* v

Solving this gives a speed of 121 mph.

Completing the table, I get the following.

  • A one percent reduction in drag gives 119 mph
  • A two percent reduction in drag gives 119 mph
  • A three percent reduction in drag gives 120 mph
  • A four percent reduction in drag gives 120 mph
  • A five percent reduction in drag gives 121 mph
  • A six percent reduction in drag gives 122 mph
  • A seven percent reduction in drag gives 122 mph
  • An eight percent reduction in drag gives 123 mph
  • A nine percent reduction in drag gives 124 mph
  • A ten percent reduction in drag gives 124 mph
  • An eleven percent reduction in drag gives 125 mph

I can certainly understand why Talgo have developed the duck-like nose.

The conclusion is that if you can achieve an eleven percent reduction in drag over the current train, then with the same installed power can raise the speed from 118 mph to 125 mph.

Why Have A Fourth Engine?

If aerodynamics can make a major contribution to the increase in speed under diesel, why add a fourth engine?

  • It might be better to fit four slightly smaller engines to obtain the same power.
  • It might be better to put a pair of engines under two cars, rather than a single engine under four cars, as pairs of engines might share ancillaries like cooling systems.
  • Extra power might be needed for acceleration.
  • Four engines gives a level of redundancy, if only three are needed to power the train.

I wouldn’t be surprised to find out, that Hitachi are having a major rethink in the traction department.

Will The Trains Have Regenerative Braking To Batteries?

I would be very surprised if they don’t, as it’s the only sensible way to do regenerative braking on diesel power.

Will The Trains Be Built Around An MTU Hybrid PowerPack?

This or something like it from Hitachi’s diesel engine supplier; MTU, is certainly a possibility and it would surely mean someone else is responsible for all the tricky software development.

It would give the following.

  • Regenersative braking to batteries.
  • Appropriate power.
  • Easier design and manufacture.
  • MTU would probably produce the sophisticated power control system for the train.
  • MTU could probably produce a twin-engined PowerPack

Rolls Royce MTU and Hitachi would all add to the perception of the train.

I would rate Hitachi using MTU Hybrid PowerPacks quite likely!

Would Two Pairs Of Engines Be Better?

The current formation of a five-car Class 800 train is as follows.

DPTS-MS-MS-MC-DPTF

Note.

  1. Both driver cars are trailers.
  2. The middle three cars all have generators, that are rated at 560 kW for a Class 800 train and 700 kW for a Class 802 train.
  3. Take a trip between Paddington and Oxford and you can feel the engines underneath the floor.
  4. The engines seem to be reasonably well insulated from the passenger cabin.

The system works, but could it be improved.

If I’m right about the aerodynamic gains that could be possible, then it may be possible to cruise at 125 mph using a power of somewhere around 1,800 kW or four diesel generators of 450 kW each.

Putting a diesel generator in four cars, would mean one of the driver cars would receive an engine, which might upset the balance of the train.

But putting say two diesel generators in car 2 and car 4 could have advantages.

  • A Class 800 train has a fuel capacity of 1,300 litres, which weighs 11.06 tonnes. and is held in three tanks. Would train dynamics be better with two larger tanks in car 2 and 4?
  • Could other ancillaries like cooling systems be shared between the two engines?
  • Could a substantial battery pack be placed underneath car 3, which now has no engine and no fuel tank?
  • As the engines are smaller will they be easier to isolate from the cabin?

The only problem would be fitting two generators underneath the shorter 24 metre car.

What size of battery could be fitted in car 3?

  • According to this datasheet on the MTU web site, the engine weighs between five and six tonnes.
  • I think this weight doesn’t  include the generator and the cooling systems.
  • Removing the fuel tank would save 3.7 tonnes

I suspect that a ten tonne battery could replace the diesel engine and its support systems in car 3..

On current battery energy densities that would be a battery of around 1000 kWh.

In How Much Power Is Needed To Run A Train At 125 mph?, I estimates that an electric  Class 801 train needs 3.42 kWh per vehicle mile to maintain 125 mph.

This would give a range of almost sixty miles on battery power.

The battery would also enable.

  • Regenerative braking to batteries, which saves energy at station stops.
  • Diesel engines would not need to be run in stations or sensitive areas.
  • Battery power could be used to boost acceleration and save diesel fuel.

You can almost think of the battery as an auxiliary engine powered by electrification and regenerative braking, that can also be topped up from the diesel generators.

It should also be noted, that by the time these trains enter service, the Midland Main Line will be electrified as far as Kettering and possibly Market Harborough.

This will enable the following.

  • Trains will leave the electrification going North with a full battery.
  • As Nottingham is less than sixty miles from Kettering and the trains will certainly have regeneratinve braking, I would not be surprised to see Northbound services to Nottingham being almost zero-carbon.
  • A charging station at Nottingham would enable Southbound services to reach the electrification, thus making these services almost zero-carbon.
  • Trains would be able to travel between Derby and Chesterfield, which is only 23 miles, through the World Heritage Site of the Derwent Valley Mills, on battery power.
  • Corby and Melton Mowbray are just 26 miles apart, so the bi-mode trains could run a zero-carbon service to Oakham and Melton Mowbray.
  • Trains could also run between Corby and Leicester on battery power.
  • If and when the Northern end of the route is electrified between Sheffield and Clay Cross Junction ion conjunction with High Speed Two, the electrification gap between Clay Cross Junction and Market Harborough will be under seventy miles, so the trains should be able to be almost zero carbon between London and Sheffield.

It does appear that if a battery the same weight as a diesel generator, fuel tank and ancillaries is placed in the middle car, the services on the Midland Main Line will be substantially zero-carbon.

What Would Be The Size Of |The Diesel Engines?

If the battery can be considered like a fifth auxiliary engine, I would suspect that the engines could be much smaller than the 560 kWh units in a Class 800 train.

Improved aerodynamics would also reduce the power needed to maintain 125 mph.

There would also be other advantages to having smaller engines.

  • There would be less weight to accelerate and lug around.
  • The noise from smaller engines would be easier to insulate from passengers.
  • Engines could be used selectively according to the train load.
  • Engines might be less prone to overheating.

The mathematics and economics will decide the actual size of the four engines.

Earlier, I estimated that a 10-11 % decrease in the trains aerodynamic drag could enable 124-5 mph with 1680 kW.

So if this power was provided by four engines instead of three, they would be 420 kW engines.

Conclusion

The Hitachi bi-modes for East Midlands Railway will be very different trains, to their current Class 80x trains.

Corby Class 360/1s Earmarked For 110 mph Running

The title of this post, is the same as that of an article on Page 10 of Issue 886 of Rail Magazine.

In Are Class 360 Trains Suitable For St. Pancras And Corby?, I came to this conclusion.

In my view there is a lot of upgrade work to be done to the Class 360 trains to make them suitable for working on the services between St. Pancras and Corby.

  • They need a new upgraded interior.
  • The trains need upgrading to at least 110 mph.
  • A possible upgrading with digital signalling.

I can’t help feeling that the Class 360 trains would make a good stop-gap, but in the long-term it might be better to have a small fleet of electric trains.

The Rail Magazine article says the following will be done.

  • Trains will be upgraded for 110 mph running.
  • 3+2 seating will be replaced by 2+2 seating.
  • Wi-fi, tables and updated information screens will be added.

This all sounds a lot better.

Are Class 360 Trains Suitable For St. Pancras And Corby?

It appears that East Midlands Railway will be using Class 360 trains on the route between St. Pancras and Corby stations running them under the branch name of EMR Electrics.

The London And St. Pancras Route

The route has the following characteristics.

  • It is just short of 80 miles long.
  • The current Class 222 trains take one hour and fifteen minutes for the journey.
  • This means these trains have a start to stop average at 64 mph.
  • Much of the route is cleared for 125 mph running.
  • The route is being made a complete double track.
  • The whole route is being electrified with 25 KVAC overhead wires.

In December 2020, the route will host a new electric service.

East Midlands Railway’s Train Specification For The Route

This page on the Department for Transport web site is an interactive map of the Abellio’s promises for East Midlands Railway.

These features are mentioned for Midland Main Line services to Corby.

  • Increased capacity
  • Twelve-car trains in the Peak.
  • More reliable service
  • Improved comfort
  • Passenger information system
  • Free on-board Wi-Fi
  • At-seat power sockets
  • USB points
  • Air conditioning
  • Tables at all seats
  • Increased luggage space
  • On-board cycle storage

What more could passengers want?

How Well Do Class 360 Trains Fit The Specification?

These are a few pictures of a Class 360 train, which I took today.

Some problems and strengths are immediately obvious.

  • There are no tables.
  • Will two+three seating e acceptable, considering that the current trains on the route have two+two seating.
  • There is no space for bicycles.
  • There are no luggage racks, which will be needed as the Corby service will also double as a service to Luton Airport.
  • The trains are in reasonably good condition.
  • There ia a fully-accessible toilet.

A lot of work will need to be done to update the interior of the trains to a standard, that fits East Midland Railway’s specification and their customers expectations.

But there is a full twelve months before the trains will be needed to run on the newly electrified route between St. Pancras and Corby stations.

This may seem enough time, but many current train refurbishment projects are running late.

Is The Performance Of Class 360 Trains Good Enough?

The current Class 222 trains have the following performance.

  • 125 mph maximum speed.
  • An acceleration rate of 0.80 m/sec/sec

By comparison the Class 360 trains have the following performance.

  • 100 mph maximum speed.
  • An acceleration rate of 0.98 m/sec/sec.

Given that much of the route between St. Pancras and Corby stastions will be constructed for 125 mph running, will the top speed of the Class 360 trains be high enough?

Will The Class 360 Trains And The Hitachi AT-300 Bi-Modes Be Compatible?

East Midlands Railway has ordered thirty-three AT-300 bi-modes, which will be able to run at 125 mph on the fully-electrified Midland Main Line to the South of Market Hsrborough station.

As thetwo trains will share the fast lines, with the Class 360 trains, will there be conflicts, as the Class 360 trains are only capable of 100 mph?

Ideally, the Class 360 trains should be upgraded to their highest speed possible.

Some of similar Class 350 trains are capable of 110 mph.

This could be enough, but surely for ease of operation, all of East Midlands Railway’s services into St. Pancras should be run by trains capable of running at 125 mph.

Will The Class 360 Trains Need Digital Signalling?

The Hitachi AT-300 trains will probably be able to run using digital signalling, which could be a valuable way of creating more paths on the Midland Main Line.

So will the Class 3560 trains be fitted with digital signalling?

Conclusion

In my view there is a lot of upgrade work to be done to the Class 360 trains to make them suitable for working on the services between St. Pancras and Corby.

  • They need a new upgraded interior.
  • The trains need upgrading to at least 110 mph.
  • A possible upgrading with digital signalling.

I can’t help feeling that the Class 360 trains would make a good stop-gap, but in the long-term it might be better to have a small fleet of electric trains.

Electric AT-300 trains must be one of the favourites, although Class 745 trains, similar to those that Abellio will run between Liverpool Street and Stansted Airport, would do nicely.

East Midlands Railway Announces Three Brands

The title if this article is the same as that of this article on Railway Gazette.

This is a quote about their electric trains to Corby, which will run under the brand name of EMR Electrics.

EMR said that once various developments had been completed, passengers would be able to reach the terminal at Luton Airport in ‘a little under half an hour’ from central London.

Currently, the fastest services going to between St. Pancras and Luton Airport Parkway stations take twenty-four minutes using 125 mph Class 222 trains with Luton Airport Parkway as the first stop.

Thameslink using 100 mph Class 700 trains take 30 minutes and more!

I question, whether the 100 mph Class 360 trains, running with Luton Airport Parkway as the first stop, can do the trip in the 24-26 minutes to get to the terminal in under half an hour, even with Luton Airport’s  DART shuttle train working!

In Are Class 360 Trains Suitable For St. Pancras And Corby?, I looked at Class 360 trains running the service between St. Pancras and Corby stations.

I came to this conclusion.

In my view there is a lot of upgrade work to be done to the Class 360 trains to make them suitable for working on the services between St. Pancras and Corby.

  • They need a new upgraded interior.
  • The trains need upgrading to at least 110 mph.
  • A possible upgrading with digital signalling.

I can’t help feeling that the Class 360 trains would make a good stop-gap, but in the long-term it might be better to have a small fleet of electric trains.

Electric AT-300 trains must be one of the favourites, although Class 745 trains, similar to those that Abellio will run between Liverpool Street and Stansted Airport, would do nicely.

So will East Midlands Railway have updated and faster Class 360 trains or will they be bringing in 125 mph trains to hit the required schedule to Luton Airport Parkway?

Conclusion

Luton Airport will have a real Airport Express!

But will the Class 360 trains, be able to deliver it? I have my doubts!

Vere Promises East Midlands Bi-Modes In 2022

The title of this post is the saqme as that of this article on Rail Magazine.

This is the first paragraph.

East Midlands Railway will have its entire bi-mode fleet in traffic by December 2022, according to Baroness Vere, the Government’s transport spokesman in the House of Lords.

This statement means that whoever manufactures the trains has just over three years from today to design, build and test the trains.

This paragraph from the article talks about how Bombardier and Hitachi would design the trains.

It’s known that Bombardier and Hitachi are interested in the contract, but both will be supplying new designs, with the former offering a bi-mode Aventra while the latter will offer an AT300 (the Intercity Express Programme platform) but with shorter vehicles.

What do we know about these two trains?

Bombardier Bi-Mode Aventra

In the July 2018 Edition of Modern Railways, there is an article entitled Bi-Mode Aventra Details Revealed.

As is typical with Bombardier interviews, they give their objectives, rather than how they aim to achieve them.

In Bombardier Bi-Mode Aventra To Feature Battery Power, I said this.

The title of this post is the same as this article in Rail Magazine.

A few points from the article.

  • Development has already started.
  • Battery power could be used for Last-Mile applications.
  • The bi-mode would have a maximum speed of 125 mph under both electric and diesel power.
  • The trains will be built at Derby.
  • Bombardier’s spokesman said that the ambience will be better, than other bi-modes.
  • Export of trains is a possibility.

Bombardier’s spokesman also said, that they have offered the train to three new franchises. East Midlands, West Coast Partnership and CrossCountry.

Very little more can be gleaned from the later Modern Railways article.

Consider.

  • Aventras are designed to a modular concept.
  • Bombardier have finally got the software for the train working to a high standard.
  • The trains are designed for ease of manufacture, at a high rate.
  • Development of the bi-mode train must have started before June 2018.
  • Christian Wolmar disclosed the objective of a 125 mph Aventra in February 2017.
  • I have seem references to Aventras, being tested at 110 mph.

On the balance of probabilities, I think it is very possible that Bombardier can deliver a full fleet of 125 mph bi-mode trains with batteries before the end of 2022.

Hitachi AT-300

Consider.

  • Class 802 trains are a version of the AT-300 train, which in turn are a member of Hitachi’s A-Train family.
  • Class 802 trains are successfully in service on the Great Western Railway.
  • Class 385, 395, 800 and 801 are all members of the A-train family and are closely related to the Class 802 train.
  • The A-Train is a modular family.and different numbers of cars and car length, shouldn’t be a problem.
  • Hull Trains ordered their fleet of five Class 802 trains in November 2016 and they will enter service around December 2019 or early in 2020.
  • First Group ordered five AT-300 trains in March 2019 and they will enter service in Autumn 2021.

If the order has been placed in the last few months, there is every chance that Hitachi could deliver a fleet of new bi-mode trains for service in December 2022.

Stadler Flirt

These aren’t mentioned in the Rail Magazine article, but they were mentioned as a possibility for the order in an article by Roger Ford, which was entitled East Midlands IC125 Dilemma, in the June 2019 Edition of Modern Railways.

This is an extract from Roger’s article.

In theory, Stadler should be in pole position. Itis also supplying Abellio’s Greater Anglia franchise, where Flirt bi-modes are running on test.

As they haven’t had any serious problems yet, and they are Swiss, everyone thinks they are amazingly efficient and wonderful. Whjich may turn out to be the case.

In the end, Roger rates their chances as slim.

But Stadler certainly has the technical capability to produce a 125 mph bi-mode train.

Electric Trains To Corby

When the electrified St. Pancras and Corby service opens in December 2020, a round trip will take three hours.

This means that as few as three trains would be needed to provide the service.

The specification would be.

  • Electric traction
  • Twelve cars and 240 metres long.
  • 125 mph capability.
  • Three trains and a spare would probably be needed by December 2020, with a further three trains by December 2021.

Abellio would also probably like the trains to be very similar for drivers and staff.

Currently, it appears that the electric services to Corby, will be run initially by cascaded Class 360 trains.

  • But with a bit of juggling of production, Bombardier, Hitachi and Stadler might be able to manufacture, the four trains needed to start the service in December 2020.
  • Abellio also have Class 360 and Class 379 trains working on Greater Anglia, that are likely to be replaced before December 2020.

So they have a sensible back-stop.

How Many Trains Will Abellio Need?

The current service is two trains per hour to both Nottingham and Sheffield.

These are fastest times.

  • London and Nottingham is one hour forty minutes
  • London and Sheffield is two hours

Even if there is a bit of a speed increase, it looks like at least eight trains will be needed for both services.

As to train length, I doubt five cars will be enough on all trains.

  • Some services are currently run by six and eight-car HSTs.
  • Have Abellio promised more seats?
  • Abellio will be extending some Sheffield services to Rotherham, Barnsley and Leeds.
  • It has already been stated that the Corby trains will be 240 metres long
  • So will we see a uniform fleet of longer trains?

There are some short platforms, so I suspect Abellio will buy a mixture of full-length 240 metre-long trains and half-length 120 metre-long trains, as several train companies have done.

I feel we could see something like eight full length trains and perhaps twelve half-length trains.

I have calculated that seven full-length trains are needed for Corby.

Adding this up gives the following.

  • Eight full-length bi-mode trains of ten-cars.
  • Seven full-length electric trains of ten-cars.
  • Twelve half-length bi-mode trains of five-cars

This gives a total of 27 trains of a total of 210 cars, of which 140 are bi-mode and 70 are electric.

All of this is based on running the current service with new trains.

abellio Greater Anglia have not not just done this in East Anglia, but have purchsed extra trains to add new services and increase frequencies.

So I would feel, that these trains are a minimum order, if Abellio are not doing any expansion.

Daily Telegraph Report – 19th July 2019

A report in the Daily Telegraph on the 19th July 2019, which is entitled Blow For Bombardier’s Derby Plant As £600m Train Contract Goes To Hitachi, says the order has gone to Hitachi.

  • Value is quoted at £600million.
  • A formal announcement is expected next week.

Has next week already passed without an announcement from Abellio?

I do find it strange, that there has been no reference to the Telegraph report in local sources around Derby.

This article on Railway Gazette is entitled Trains Ordered For 2021 Launch Of ‘High-Quality, Low Fare’ London – Edinburgh Service.

FirstGroup have ordered AT-300 trains.

  • All-electric.
  • Five trains of five-cars.
  • A total order value of £100 million.
  • Order placed in March 2019
  • Service starting in Autumn 2021

This works out at four million pounds per car.

Earlier, I calculated that Abellio needed to buy 140 bi-mode cars and seventy electric ones.

Assuming that Abellio run the Corby services with refurbished Class 360 trains, then 140 carriages will cost £560 million.

But this would mean the following.

  • Abellio would be running two separate fleets on the Midland Main Line.
  • The Corby services would run below the operating speed of the route.
  • Expansion would mean the purchase of more trains.

This is very different to their philosophy in Abellio Greater Anglia.

  • Class 745 and Class 755 trains are very similar to drivers and other staff.
  • Both trains can operate at 100 mph on the Great Eastern Main Line.
  • Abellio Greater Anglia have significantly increased the size of their train fleet.

I believe that Bombardier, Hitachi and Stadler can all met this schedule.

  • Deliver four 125 mph electric trains by a date early enough for a December 2020 start for Corby services.
  • Deliver another three 125 mph electric trains by December 2021 for two trains per hour to Corby.
  • Deliver the fleet of 125 mph bi-mode electric trains by December 2022 for Derby,Nottingham, Sheffield and beyond.

At four million pounds for a car for a Hitachi train, this works out at £840 million.

So could it be, that Hitachi have thrown in a good discount to make sure of the order.

It will be very interesting, when Abellio announce their order.

Interim Trains

Baroness Vere also discussed the other trains on the Midland Main Line.

This was the final two paragraph from the article.

As it stands, the 12 High Speed Trains cannot operate in passenger traffic beyond December 31 2019 this year, as they will not meet new accessibility regulations.

When announcing the Abellio contract win in April, Government confirmed that four Class 180s would transfer from Hull Trains to EMR. There was also the possibility that the LNER HSTs could also transfer to the MML, although these do not meet the disability requirements either.

So what is going to happen?

It appears that the four Class 180 trains and the twenty-seven Class 222 trains of various lengths will have to manage.

But I do think, that Baroness Vere’s statement.

East Midlands Railway will have its entire bi-mode fleet in traffic by December 2022.

Is very welcome, as the HSTs will retire on the 31st December 2019 and there will be less than three years of a reduced fleet.

These points should also be noted.

  • In December 2020, when the electrification goes live and new electric trains start running between London and Corby, there will be a few more Class 222 trains available.
  • The Corby electric trains, will also add capacity between London and Kettering.
  • I don’t think it unlikely, that some other trains are rustled up to fill the gaps using perhaps Mark 4 coaches and Class 43 locomotives.

I hope for Abellio’s and their passengers sake, that what Baroness Vere said, comes true!

Could Abellio Go For A Safety-First Solution?

Consider.

  • Abellio Greater Anglia’s new Class 745, Class 755 and Class 720 trains are all running, if not years, but a few months late.
  • There has been nothing serious and Greater Anglia only has one fleet that is not PRM-compliant; the London and Norwich expresses.
  • Providing all goes reasonably well with the introduction of the new Class 745 trains, Greater Anglia’s fleet will be fully PRM-compliant, by the end of the year.

But if they had opted for off-the-shelf Hitachi Class 801 trains for London and Norwich, there might have been less worry. On the other hand, Hitachi way of making trains, by shipping the bodies from Japan probably doesn’t lead itself to high productio rates.

But for Midland Main Line services, Abellio East Midlands Railway aren’t looking at a large fleet of trains.

I estimate they could need.

  • Eight full-length bi-mode trains of ten-cars.
  • Seven full-length electric trains of ten-cars.
  • Twelve half-length bi-mode trains of five-cars

Now that Hitachi’s big orders are coming to an end, Abellio can probably be sure, they will get the main line trains on time and with the minimum of fuss.

Going the safety-first route of buying a fleet of Hitachi trains could deliver the trains that are needed urgently.

  • Four 125 mph electric trains by a date early enough for a December 2020 start for Corby services.
  • Another three 125 mph electric trains by December 2021 for two trains per hour to Corby.
  • A fleet of 125 mph bi-mode electric trains by December 2022 for Derby,Nottingham, Sheffield and beyond.

It might be a bit tight for the Corby electrics, but other trains that could work the route in the interim are available.

Abellio could do a lot worse than give Hitahi the order, if they could deliver early!

Conclusion

If any of the three train manufacturers can supply new trains for the St. Pancras and Corby service to the tight timetable, Abellio would surely be very pleased, as they would only have one train type to introduce on the route.

But I do think, that there is a possibility, that a good discount has won it for Hitachi!

East Midlands Railway’s New Look

The title of this post, is the same as a short article in Issue 882 of Rail Magazine.

What is interesting, is that it shows a visualisation of a Class 360 train in the new livery.

In Abellio East Midlands Railway’s Plans For London And Corby, I came to this conclusion.

I wouldn’t be surprised, if East Midlands Railway brought in Class 379 or Class 360 trains as a stop-gap and replaced them with electric versions of the bi-modes in 2022.

The best solution would be to obtain three twelve-car all-electric versions of the bi-modes by December 2020, to run the initial service.

Hitachi has a 125 mph electric Class 801 train and a 125 mph bi-mode Class 802 train.
Stadler has a 125 mph electric version of Greater Anglia’s Class 745 train and I suspect a compatible 125 mph bi-mode train.
Bombardier are working on a 125 mph bi-mode Aventra and have been quoted as saying Aventras can be stretched to 125 mph.

It will be interesting to see what trains East Midlands Railway chooses.

By showing, a Class 360 train in their new livery, are they attempting to do one or all of the following.

  • Get better terms for the nine interim trains they may need.
  • Get better terms and earlier delivery for enough new twelve-car electric trains to run a 125 mph service between London and Corby.
  • Trying to get better terms with the leasing companies to take back Class 379 and Class 360 trains, currently at Greater Anglia.

The Dutch can be tough negotiators.

Abellio East Midlands Railway’s Plans For London And Corby

This page on the Department for Transport web site is an interactive map of the Abellio’s promises for East Midlands Railway.

These are mentioned for Midland Main Line services to Corby.

Dedicated Corby – St Pancras Express Service Will Be Introduced From December 2020 With 12-car Trains In The Peaks

In 2020, the route between London and Corby will have been improved.

  • It will be fully electrified.
  • There will be double-track between Kettering and Corby.
  • Corby station will have a second platform.
  • 125 mph running will be possible in sections of the route between London and Corby.
  • Twelve-car trains indicate, that the rolling stock would be modern electric multiple units.

Possible trains include.

There must also be the possibility, for a train manufacturer to deliver enough new trains to run the London and Corby service.

To run the current hourly service, three trains are needed, so if each train was three four-car electric multiple units, nine trains would be needed.

As these electric trains will need to mix it with the 125 mph trains on the fast lines between St. Pancras and Kettering, 110 mph trains would probably be preferable.

Class 387 trains were originally mooted for this route, but they all seem to have been snapped up by other operators, who may be reluctant to let them go.

On the other hand, as I wrote in When Crossrail Opens To Reading, Will Great Western Railway Have Too Many Class 387 Trains?, Great Western Railway may have a few trains going spare.

The three other possible trains are both used in Abellio-run franchises.

  • ,Abellio Greater Anglia are replacing their thirty Class 379 trains with new Stadler Class 745/1 trains in 2019.
  • Abellio Greater Anglia are replacing their twenty-one Class 360 trains with new Bombardier Class 720 trains in 2020.
  • West Midlands Trains have a large fleet of Class 350 trains.

Greater Anglia’s plans currently give the order of the new Stadler fleet introduction as.

  • Four-car Class 755/4 trains
  • Twelve-car Class 745/0 trains for London and Norwich services
  • Three-car Class 755/3 trains
  • Twelve-car Class 745/1 trains for London and Stansted services

All trains are to be introduced by the end of 2020.

The Bombardier Class 720 trains are also planned to be introduced by the same date, starting this Autumn.

Could this mean that it is likely that nine Class 379 or Class 360 trains could be available before the end of 2019?

If Class 379 or Class 360 trains are used to Corby, it would allow a very relaxed train introduction.

There could be at least a year, to turn the trains into perfect trains for a high-capacity London and Corby service.

I think using Class 387 and Class 350 trains wouldn’t be so simple.

As the Class 745/1 trains for London and Stansted could be the last to be delivered, which might delay the release of the Class 379 trains, could this explain the rumours for using the Class 360 trains, between London and Corby.

There is also an interesting possibility.

Suppose, Abellio decided to order 125 mph trains from Stadler identical to the Class 745/0 trains between London and Norwich on the route between London and Corby.

  • Stadler probably knows how to upgrade the trains to 125 mph, as there are electric Flirts in Norway with this performance.
  • Greater Anglia have invested heavily in driver simulators and training aids for their Stadler trains.
  • By the end of 2019, they will be running Class 745/0 trains between London and Norwich.

With different colours and a few route-specific details, the London and Norwich Class 745/0 trains, would surely be more than acceptable for London and Corby.

Stadler would surely be able to build the extra trains before the Stansted trains. This would mean that the unwanted Class 379 trains would have to soldier on to Stansted for a few more months.

125 mph Class 745 trains would be a magnificent upgrade to the London and Corby service.

Corby – London Service Doubled To Two Trains Per Hour All Day

This would mean the need would be eighteen four-car trains. or six twelve-car trains.

There are enough Class 379 and Class 360 trains, but obtaining the originally-planned Class 387 trains could be problematic.

Building the three extra new trains would not be a problem.

Kettering, Luton And Luton Airport Parkway Services Provided With 2 Trains Per Hour for Most Of The Day

Note.

  1. Luton station is on the latest list of stations to be made step-free by 2024.
  2. Luton Airport has been agitating for more fast trains to and from London and now gets a half-hourly express.
  3. Luton Airport Parkway station will have the Luton DART connection to the Airport in 2021.
  4. Class 379 trains are designed for airport services.

It appears to be a better service for passengers.

Enhanced Sunday Service Throughout The Route With Regular Direct Sunday Services Between London And Corby

No passenger complaints here.

Refurbished Modern Express Trains From December 2020

Features include.

  • Increased capacity
  • More reliable service
  • Improved comfort
  • Passenger information system
  • Free on-board Wi-Fi
  • At-seat power sockets
  • USB points
  • Air conditioning
  • Tables at all seats
  • Increased luggage space
  • On-board cycle storage

What more could passengers want?

Many of these features are already installed in the Class 379 trains and would be no problem.

  • When I rode the BEMU Trial train between Maningtree and Harwich, the information on the Class 379 train was word perfect.
  • The trains are reliable and comfortable.
  • Wi-fii, power sockets, air-conditioning and increased luggage space are already fitted.
  • The trains have lots of tables, but not at every seat.

These are a selection of pictures of the interior of a Class 379 train.

Updating the interior of the trains would not be a major problem.

Class 360 Trains Would Need A Substantial Refurbish

If Class 360 trains were to be used to Corby, they would need a substantial refurbish, but the general feeling is that this would be possible and there is a year to do it.

iNew-Build Class 745 Trains

With a small fleet of new-build Class 745 trains, the customer would get what they want! – Tables, 2+2 seating, wi-fi sockets etc.

The Greater Anglia London and Norwich specification would be a good starting point.

Will The Class 379 Trains Be Fitted With Batteries?

The BEMU Trial in 2015, showed that this was feasible. Abellio was involved in this trial and must have their own views on the technology.

  • Depots are safer places.
  • Electrification can be simpler.
  • Regenerative braking can be handled on the train without using the overhead wires for return currents.
  • Batteries increase train efficiencies.

This picture shows, the wires are going up at Corby.

So it doesn’t look like battery power will be used to Corby.

But batteries could still be fitted for efficiency and safety reasons or possibly to power the trains to Oakham and Melton Mowbray.

What About The Rumour Suggesting Class 360 Trains Will Be Used?

These are some pictures of a Class 360 train.

Consider.

  • The Class 360 trains have a 2+3 interior with few if any tables.
  • If Bombardier deliver the Class 720 trains, later than planned, availability of the Class 360 trains for Corby could be tight.
  • Could they be prated to 110 mph trains, if that was felt necessary?

I feel that there would be a lot more work to prepare the trains for Corby and a higher chance, they would be late!

I think except as a stop-gap, it is unliklely that Class 360 trains will be used between London and Corby.

Will The Trains Be Replaced In A Few Years?

Consider.

  • The London and Corby route is 79.5 miles long and takes 75 minutes with four stops, which is an average speed of 64 mph.
  • At present, services between London and Corby are run using 125 mph Class 222 trains.
  • The Class 222 trains have better acceleration than an InterCity 125 and much better acceleration than a Class 360 train.
  • The London to Corby route is a less-than-125 mph route.
  • Network Rail ia currently improving the electrification between London and Bedford, so that the route between London and Corby will be an electrified 125 mph route.
  • None of the trains being considered for the service between London and Corby is faster than 110 mph.

Does all this mean that Corby services might be slower after electrification?

  • Will the 125 mph upgrade to the track and electrification ensure the electric trains are faster, even if they are 100 mph trains.
  • Well-driven 100-110 mph trains might be as fast.

However, the Derby, Nottingham and Sheffield expresses might be slowed, just as they are by the 100 mph Thameslink trains.

In the article in Issue 877 of Rail Magazine, four manufacturers are suggested for the bi-mode trains that will be used between London and Derby, Nottingham and Sheffield from 2022.

  • Bombardier
  • Hitachi
  • Stadler
  • Talgo

Hitachi are the only manufacturer with 125 mph bi-mode trains on the UK Network.

They have a near-identical bi-mode Class 802 train and an all-electric Class 801 train.

  • Both are capable of 125 mph running.
  • Conversion between the two trains involves changing the number of engines.
  • Drivers are probably trained to drive both types of train.

Ideally, on the Midland Main Line, electric trains could run to Corby, with bi-mode trains running to Derby, Nottingham and Sheffield.

So when the 125 mph bi-mode trains are delivered in 2022, would it be sensible to run their 125 mph electric cousins to Corby?

  • South of Market Harborough, all East Midlands Railway trains would be 125 mph electric trains, running on 125 mph tracks.
  • One tph between London and Corby would need three twelve-car trains.
  • Two tph between London and Corby would need six twelve-car trains.

If that is the case, then whatever train is run to Corby from December 2020, is only a stop-gap for a couple of years, where only nine four-car trains would be needed.

Would it be more economic in the long term to place the order for the bi-mode trains, with a manufacturer, who can deliver three all-electric trains by December 2020?

I believe Stadler could do that!

Conclusion

I’m fairly certain, that services between London and Corby could be run by refurbished Class 379 trains.

As there is plenty of time before service introduction, this could be a very relaxed and painless introduction of new trains. Unlike some others recently.

There may even be time to upgrade the top speed of the trains, so they fit in better with East Midlands Railway’s 125 mph expresses.

I wouldn’t be surprised, if East Midlands Railway brought in Class 379 or Class 360 trains as a stop-gap and replaced them with electric versions of the bi-modes in 2022.

But the best solution would be to obtain three twelve-car all-electric versions of the bi-modes by December 2020, to run the initial service.

  • Hitachi has a 125 mph electric Class 801 train and a 125 mph bi-mode Class 802 train.
  • Stadler has a 125 mph electric version of Greater Anglia’s Class 745 train and I suspect a compatible 125 mph bi-mode train.
  • Bombardier are working on a 125 mph bi-mode Aventra and have been quoted as saying Aventras can be stretched to 125 mph.

It will be interesting to see what trains East Midlands Railway chooses.

But I think Stadler Class 745 trains are a distinct possibility.

  • Abellio will have experience of running these trains and training drivers and other staff.
  • 125 mph trains could be almost identical to those on London and Norwich services.
  • Stadler have built 125 mph electric Flirts for Norway.

By juggling production a bit, they could be delivered on time for a December 2020 start of services.

Comparing Greater Anglia’s Old And New Electric Multiple Units

Currently, Greater Anglia has the following electric multiple units, which will be replaces by new Class 720 trains.

Class 317 Train

  • 68 x 4 car trains
  • Length 79.32 metres.
  • 100 mph operating speed.
  • Acceleration of 0.55 metre per second²
  • No regenerative braking
  • Capacity – 260/290 seats.
  • First Class section

Note the acceleration seems to be standard for all BR EMUs

Class 321 Train

  • 104 x 4 car trains
  • Length 79.8 metres.
  • 100 mph operating speed.
  • Acceleration of 0.55 metre per second²
  • Regenerative braking can be fitted.
  • Capacity – 309 seats.
  • First Class section

Thirty trains are being upgraded to the Class 321 Renatus

Class 360 Train

  • 21 x 4 car trains
  • Length 81.36 metres.
  • 100 mph operating speed.
  • Acceleration of 0.98 metre per second²
  • Regenerative braking.
  • Capacity – 280 seats.
  • First Class section

These are the specifications of the two lengths of new Class 720 trains.

Class 720 Train – Five Car

89 x 5-car trains

Length 122 metres

Capacity – 544 seats and 145 standing.

Class 720 Train – Ten Car

22 x 10-car trains

Length 243 metres

Capacity – 1145 seats and 290 standing.

All trains will have the following.

  • 100 mph operating speed.
  • Acceleration of 1 metre per second²
  • Regenerative Braking (Using batteries?)
  • No First Class section.

Also, these trains are modern trains will all the features passengers, staff and train operators need and desire.

How Do Old And New Trains Compare?

Ten-Car Class 720 Trains

Note that these trains are just over 240 metres long, which is conveniently the length of three Class 321 or Class 360 trains.

When the order for the Class 720 trains was announced, this was said to have been a design criteria.

So will the twenty-one Class 360 trains, which regularly run as twelve-car trains be replaced by seven Class 720 trains?

  • There will be 1145 seats in the new trains, as opposed to 840 in the old.
  • There will be a Universal Access Toilet and three other toilets in the new trains, as opposed to a Universal Access Toilet in each train.
  • The new trains won’t have any First Class.
  • The new trains will be walk-through, with no intermediate cabs.
  • Operating speed and acceleration appears to be almost the same.
  • The new trains will have a lot more of the things passengers need.

It appears, that everybody could be a winner.

  • Passengers have 36 % more seats and better facilities.
  • On-board staff can handle the whole train without needing to get off to reach the other trains.
  • Network Rail won’t need to do much work to prepare for the new trains, as they fit the current platforms.
  • Maintenance of one train instead of three must be easier and less costly.

Most of these arguments also apply to replacing a three-train formation of Class 321 trains, which would give a capacity increase of 24 % more seats.

But there is one big difference.

The acceleration of Class 720 trains is nearly twice that of a Class 321 train, so there could be time savings on routes like Southend and ones with a higher number of stopss.

Destinations which the new ten-car trains from Liverpool Street station could serve include, with current frequencies in train per hour (tph)

  • Bishop’s Stortford
  • Cambridge – One tph
  • Cambridge North – One tph
  • Clacton – One tph
  • Colchester
  • Ipswich – One tph
  • Norwich
  • Southend – Three tph

With the current services and the timetable improvements, the new trains would bring could mean the following trains would be needed for

  • Cambridge – 2 trains for 1 tph
  • Cambridge North – 3 trains for 1 tph
  • Clacton – 3 trains for 1 tph
  • Ipswich – 2 trains for 1 tph
  • Southend – 8 trains for 4 tph

This is a total of eighteen trains, which would mean ideas like extending some of the Ipswich services to Norwich are possible.

One of the beauties of modern train design, is that lengthening and shortening trains is a relatively easy process, that was invented by Lego and refined by Microsoft with Plug-and-Play!

Five-Car Class 720 Trains Replacing The Current Eight-Car Services

Some destinations like Braintree, Colchester Town, Harwich, Kings Lynn and Walton-on-the-Naze can’t accommodate the current twelve car trains, so they can’t be served by new ten-car Class 720 trains.

So how does a five-car Class 720 train compare with two Class 321 or 360 trains working as an eight-car train.

  • There will be 544 seats and 146 standees in a five-car Class 720 train.
  • There will be 560 seats in an eight-car formation of Class 360 trains.
  • There will be 618 seats in an eight-car formation of Class 321 trains.
  • There will be about 440 seats in an eight-car formation of Class 317 trains
  • The new trains are 122 metres long, whereas the current eight-car trains are 160 metres long.
  • All trains have a 100 mph operating speed.
  • The Class 720 and 360 trains have an acceleration of around 1 metre per second², whereas the acceleration of a Class 321 train is only 0.55 metre per second².

Given that the Class 720 is a modern train, designed with passengers, staff and operators in mind, I can’t see any problems with replacing the current eight-car trains with a five-car Class 720 train.

I also suspect that if required, an extra car could be added to make six-car trains with a length of 146 metres, that would be shorter than an eight-car Class 321 train.

Five-Car Class 720 Trains Replacing The Current Four-Car Services

There is only one electric service on Greater Anglia, that needs to be run using a four-car train and that is the service between Wickford to Southminster stations on the Crouch Valley Line.

Under Infrastructure in the |Wikipedia entry for the Crouch Valley Line, this is said.

Only Wickford and South Woodham Ferrers have platforms long enough to accommodate 12-coach trains, while each of the other stations on the line can accommodate eight coaches, though services on the line are typically only formed of four carriages due to the short terminus platforms at Wickford being able to only accommodate one four car unit.

So it would appear that the platform at Wickford station needs to be lengthened!

Or does it?

I’ve read that Greater Anglia plan to run four tph between Liverpool Street and Southend Victoria stations, so trains will pass through Wickford station in both directions every fifteen minutes.

Helpfully, both services seem curently to be in the station at the same time.

So if this happens after the fourth train is added to the schedule, there will be a fifteen minute window, where there is no train movements at Wickford station.

So instead of using the current platform, a five-car Class 720 train could stop in one of the main platforms to discharge and pick-up passengers.

Hopefully, the better acceleration of the Class 720 trains could be able to run along the branch in well under thirty minutes to allow a genuine two tph service, as opposed to the current difficult timetable of a train every forty minutes.

Greater Anglia does run other four-car trains at times, but surely running a five-car train wouldn’t really matter and it may attract more passengers.

Conclusion

Greater Anglia seem to have made a good choice of train size.

Transport for London’s New Rail Line

Today, Transport for London have taken over Heathrow Connect, in preparation for the full Crossrail.

The service is now run by TfL Rail, just like the Liverpool Street to Shenfield service in the East of London.

It’s even shown on some of the new Underground maps.

I photographed this map at Kings Cross St. Pancras.

Note the double blue line, which indicates the new route of the former Heathrow Connect, running from Paddington in the top-right corner of the map to Heathrow Terminal 4 towards the bottom-left.

The intermediate stations shown are.

Note that TfL use Heathrow Terminal 2 & 3 for the main railway station at Heathrow and Wikipedia uses Heathrow Central.

A Trip To Heathrow From Paddington

This morning, I checked into the new TfL Rail service at Paddington, using my Freedom Pass and took the 09:11 service to Heathrow Airport.

I got out at Heathrow Terminal 2 & 3 station before returning later on another TfL Rail service to Paddington.

I took these pictures on the route.

Note that the Class 360 trains are still running on the route, as there are operational issues with Crossrail’s new Class 345 trains in the tunnel to Heathrow.

Contactless Card/Oyster To Heathrow

TfL Rail also accepts contactless card or Oyster on this route.

According to TfL’s Single Fare Finder, the single fare is £10.20 in the Peak and £10.10 in the Off-Peak.

But,I’m not sure about railcards, the affect of capping or the price if you buy the ticket on line.

Freedom Passes To Heathrow

As I’d used my Freedom Pass, the two journeys cost me a big fat nothing!

It won’t be long before the many Freedom Pass holders, will realise, that Heathrow will be in their free travel area by a comfortable train and they will possibly use it more often, than the Piccadilly Line.

TfL Rail Service Frequency

Currently, the frequency between Paddington and Heathrow is two trains per hour (tph).

Provisional service details are shown under Services in the Wikipedia entry for Crossrail, when the line opens fully in December 2019.

  • Four tph between Abbey Wood and Heathrow Terminal 4 stations
  • Two tph between Abbey Wood and Heathrow Terminal 5 stations

All services will call at the following stations.

  • All stations between Abbey Wood and Paddington stations.
  • Ealing Broadway station
  • Heathrow Terminal 2 & 3 station.

Plans for stopping at Acton Main Line, West Ealing, Hanwell, Southall and Hayes & Harlington stations are yet to be decided.

I suspect that TfL would like all Heathrow trains to stop at all intermediate stations, just as services do between Liverpool Street and Shenfield, in the East of London.

But Great Western Railway may have other ideas!

Speaking for myself, I’d like to see four tph on the TfL Rail route between Paddington and Heathrow, as soon as possible.

The Future Of The Class 360 Trains

When Crossrail sort out the Class 345 trains, the five sets of five-car Class 360 trains will be surplus to requirements.

They will also be joined in the sidings in a couple of years, by twenty-one similar four car trains, that are being replaced with new Class 720 trains, by Greater Anglia.

As they are modern 100 mph trains, they should find a home somewhere!

They could even be exported to Thailand, where a similar fleet operates.
