Thoughts On Faster Trains On Thameslink

The Class 700 trains used by Thameslink only have an operating speed of 100 mph.

I do wonder, if that is a fast enough operating speed for all Thameslink routes.

Sharing The Midland Main Line With 125 mph Trains

A couple of years ago, I travelled back into St. Pancras with a group of East Midlands drivers in a Class 222 train.

They told me several things about the route including that the bridge at the South of Leicester station would be difficult to electrify, as it was low and the track couldn’t be lowered as one of Leicester’s main sewers was under the tracks at the bridge. Perhaps, this is one place, where discontinuous electrification could be used on the Midland Main Line.

They also told me, that sometimes the Thameslink trains were a nuisance, as because of their 100 mph operating speed, the 125 mph Class 222 trains had to slow to 100 mph.

Upgrading Of The Midland Main Line South Of Bedford

The electrification of the Midland Main Line South of Bedford is being updated, so that it is suitable for 125 mph running.

An Analysis Of Services On The Midland Main Line South Of Bedford

The current Class 222 trains are capable of 125 mph and will be replaced by Class 810 trains capable of the same speed on both diesel and electricity.

Currently, a Class 222 train is capable of doing the following on a typical non-stop run between St. Pancras and Leicester.

  • Covering the 30 miles between St. Albans and Bedford in 17 minutes at an average speed of 106 mph.
  • Covering the 50.3 miles between Bedford and Leicester in 30 minutes at an average speed of 100.6 mph.
  • Maintaining 125 mph for long stretches of the route, once the trains is North of London commuter traffic at St. Albans

I can estimate the timings on the 79.2 miles between Leicester and St. Albans, by assuming the train runs at a constant speed.

  • 100 mph – 47.5 minutes
  • 110 mph – 43.2 minutes
  • 125 mph – 38 minutes
  • 140 mph – 34 minutes

Note.

  1. I have done the calculation for 140 mph, as that is the maximum operating speed of the Class 810 train with full in-cab digital signalling.
  2. Trains have been running at 125 mph for a couple of decades on the Midland Main Line.
  3. To get a St. Pancras and Leicester time add another 14 minutes, which is the current time between St. Pancras and St. Albans of a Class 222 train.
  4. Some Off Peak trains are timed at 62-63 minutes between St. Pancras and Leicester.
  5. A time of under an hour between St. Pancras and Leicester might be possible and the Marketing Department would like it.
  6. As Thameslink trains between Bedford and St. Albans stop regularly, they are on the slow lines of the four-track railway, to the North of St. Albans.
  7. South of St. Albans, Thameslink trains often run on the fast lines.

I can expect that East Midlands Railway will want to be running their new Class 810 trains as far as far South as they can at 125 mph, to speed up their services. When the signalling allows it, they’ll want to run at 140 mph.

So they won’t want to see Thameslink’s slow trains on the fast lines.

  • But if you look at the Thameslink trains that do run on the fast lines between St. Albans and St. Pancras, they appear to be the four trains per hour (tph) that run to and from Bedford.
  • Of these trains, two tph terminate at Brighton and two tph terminate at Gatwick Airport.
  • The average speed of a Class 222 train between St. Albans and St. Pancras assuming 14 minutes for the 19.7 miles is 84.4 mph.

So it looks to me that a 100 mph Thameslink train could be able to get away without slowing the East Midland Railway expresses.

But then that is not surprising, as for many years, the Class 222 trains worked happily with 100 mph Class 319 trains.

Is There Scope For Extra And Faster Services Into St. Pancras?

I have only done a simple calculation, but I do wonder if there is scope for the following.

  • Increasing the frequency of trains for both Thameslink and East Midlands Railway.
  • Saving a few minutes on East Midlands Railway services.

Consider.

  • The new Class 810 electric trains will probably have better acceleration and deceleration than the current Class 222 diesel trains, when working using electric power.
  • East Midlands Railway is introducing Class 360 trains that were built as 100 mph trains by Siemens, who are now upgrading them to 110 mph trains.
  • Can Siemens do the same for the Class 700 trains and create a sub-fleet capable of 110 mph running?
  • All trains will be running under full in-cab digital signalling with a large degree of automatic train control.

I feel that if the Class 700 trains had the extra speed, they would make the planning of services South of St. Albans easier and allow the Class 810 trains to both run faster and provide more services.

Sharing The East Coast Main Line With 125 mph Trains

The following Thameslink services run up the East Coast Main Line past Stevenage.

  • Cambridge And Brighton – Two tph – Stops at Royston, Ashwell and Morden (1 tph), Baldock, Letchworth Garden City, Hitchin, Stevenage, Finsbury Park, London St Pancras International, Farringdon, City Thameslink, London Blackfriars, London Bridge, East Croydon, Gatwick Airport, Three Bridges, Balcombe, Haywards Heath and Burgess Hill
  • Cambridge and Kings Cross – Two tph – Stops at Foxton, Shepreth, Meldreth, Royston, Ashwell and Morden, Baldock, Letchworth Garden City, Hitchin, Stevenage, Knebworth, Welwyn North, Welwyn Garden City, Hatfield, Potters Bar and Finsbury Park
  • Peterborough and Horsham – Two tph – Stops at Huntingdon, St Neots, Sandy, Biggleswade, Arlesey, Hitchin, Stevenage, Finsbury Park, London St Pancras International, Farringdon, City Thameslink, London Blackfriars, London Bridge, East Croydon, Coulsdon South, Merstham, Redhill, Horley, Gatwick Airport, Three Bridges, Crawley, Ifield, Faygate (limited) and Littlehaven

Note.

  1. Services are generally run by Class 700 trains, although lately the Kings Cross service seems to use Class 387 trains, which have a maximum speed of 110 mph and a more comfortable interior with tables.
  2. It is intended that the Cambridge and Kings Cross service will be extended to Maidstone East by 2021.

In addition there are two Cambridge Express and Fen Line services.

  • Kings Cross and Ely – One tph – Stops at Cambridge and Cambridge North.
  • Kings Cross and King’s Lynn – One tph – Stops at Cambridge, Cambridge North, Waterbeach, Ely, Littleport, Downham Market and Watlington

Note.

  1. These services are generally run by Class 387 trains.
  2. Cambridge and King’s Cross is timetabled at around fifty minutes.

Adding all of this together means that slower services on the East Coast Main Line are comprised of the following in both directions.

  • Three tph – 110 mph – Class 387 trains
  • Four tph – 100 mph – Class 700 trains

These seven trains will have to be fitted in with the 125 mph trains running services on the East Coast Main Line, for LNER, Grand Central, Hull Trains and East Coast Trains.

There are also the following problems.

  • All trains must navigate the double-track section of the East Coast Main Line over the Digswell Viaduct and through Welwyn North station.
  • The King’s Cross and Cambridge service stops in Welwyn North station.
  • Full in-cab digital signalling is being installed on the East Coast Main Line, which could increase the speed of the expresses through the double-track section.

Could the introduction of the Class 387 trains on the Cambridge and King’s Cross service have been made, as it easier to fit in all the services if this one is run by a 110 mph train?

However, the full in-cab digital signalling with a degree of automatic train control could be the solution to this bottleneck on the East Coast Main Line.

  • Trains could be controlled automatically and with great precision between perhaps Hatfield and Stevenage.
  • Some expresses might be slowed to create gaps for the Cambridge and Peterborough services.
  • The Hertford Loop Line is also getting full in-cab digital signalling, so will some services be sent that way?

In Call For ETCS On King’s Lynn Route, I talked about a proposal to improve services on the Fen Line. This was my first three paragraphs.

The title of this post, is the same as that on an article in Edition 849 of Rail Magazine.

The article is based on this document on the Fen Line Users Aoociation web site, which is entitled Joint Response To Draft East Coast Main Line Route Study.

In addition to ETCS, which could improve capacity on the East Coast Main Line, they would also like to see journey time reductions using trains capable of running at 125 mph or faster on the King’s Lynn to Kings Cross route.

My scheduling experience tells me that a better solution will be found, if all resources are similar.

Hence the proposal to run 125 mph trains between King’s Cross and King’s Lynn and probably Ely as well, could be a very good and logical idea.

If the Class 700 trains were increased in speed to 110 mph, the trains through the double-track section of the East Coast Main Line would be.

  • One tph – 110 mph – Class 387 trains
  • Four tph – 110 mph – Class 700 trains
  • Two tph – 125 mph – New trains

Note.

  1. This would probably be an easier mix of trains to digest with the high speed services, through the double-track section.
  2. I like the idea of extending the Ely service to Norwich to give Thetford, Attleborough and Wymondham an improved service to London, Cambridge and Norwich.

The new trains would probably be a version of Hitachi’s Regional Battery Train.

  • It would need to be capable of 125 mph on the East Coast Main Line.
  • If the Ely service were to be extended to Norwich, this section would be on battery power.

There are certainly a lot of possibilities.

But as with on the Midland Main Line, it looks like for efficient operation, the operating speed of the Class 700 trains on the route needs to be increased to at least 110 mph.

Could Faster Class 700 trains Improve Services To Brighton?

These are the Thameslink services that serve Bedford, Cambridge and Peterborough, that I believe could be run more efficiently with trains capable of at running at speeds of at least 110 mph.

  • Bedford and Brighton – Two tph
  • Bedford and Gatwick Airport – Two tph
  • Cambridge and Brighton – Two tph
  • Cambridge and Maidstone East – Two tph
  • Peterborough and Horsham – Two tph

Note.

  1. I have assumed that the Cambridge and King’s Cross service has been extended to Maidstone East as planned.
  2. Eight tph serve Gatwick Airport.
  3. Four tph serve Brighton.

The Gatwick Express services have a frequency of two tph between London Victoria and Brighton calling at Gatwick Airport is already run by 110 mph Class 387 trains.

It would appear that if the Bedford, Cambridge and Peterborough were run by uprated 110 mph Class 700 trains, then this would mean that more 110 mph trains would be running to Gatwick and Brighton and this must surely improve the service to the South Coast.

But it’s not quite as simple as that, as the Cambridge and Maidstone East services will be run by eight-car trains and all the other services by twelve-car trains.

Conclusion

There would appear to be advantages in uprating some or possibly all of the Class 700 trains, so that they can run at 110 mph, as it will increase capacity on the Brighton Main Line, East Coast Main Line and Midland Main Line.

Will Hitachi Announce A High Speed Metro Train?

As the UK high speed rail network increases, we are seeing more services and proposed services, where local services are sharing tracks, where trains will be running at 125 mph or even more.

London Kings Cross And Cambridge/Kings Lynn

This Great Northern service is run by Class 387 trains.

  • Services run between London Kings Cross and Kings Lynn or Cambridge
  • The Class 387 trains have a maximum operating speed of 110 mph.
  • The route is fully electrified.
  • The trains generally use the fast lines on the East Coast Main Line, South of Hitchin.
  • Most trains on the fast lines on the East Coast Main Line are travelling at 125 mph.
  • When in the future full digital in-cab ERTMS signalling is implemented on the East Coast Main Line, speeds of up to 140 mph should be possible in some sections between London Kings Cross and Hitchin.

I also believe that digital signalling may be able to provide a solution to the twin-track bottleneck over the Digswell Viaduct.

Consider.

  • Airliners have been flown automatically and safely from airport to airport for perhaps four decades.
  • The Victoria Line has been running automatically and safely at over twenty trains per hour (tph) for five decades. It is now running at over 30 tph.
  • I worked with engineers developing a high-frequency sequence control system for a complicated chemical plant in 1970.

We also can’t deny that computers are getting better and more capable.

For these reasons, I believe there could be an ERTMS-based solution to the problem of the Digswell Viaduct, which could be something like this.

  • All trains running on the two track section over the Digswell Viaduct and through Welwyn North station would be under computer control between Welwyn Garden City and Knebworth stations.
  • Fast trains would be slowed as appropriate to create spaces to allow the slow trains to pass through the section.
  • The driver would be monitoring the computer control, just as they do on the Victoria Line.

Much more complicated automated systems have been created in various applications.

The nearest rail application in the UK, is probably the application of digital signalling to London Underground’s Circle, District, Hammersmith & City and Metropolitan Lines.

This is known at the Four Lines Modernisation and it will be completed by 2023 and increase capacity by up to twenty-seven percent.

I don’t think it unreasonable to see the following maximum numbers of services running over the Digswell Viaduct by 2030 in both directions in every hour.

  • Sixteen fast trains
  • Four slow trains

That is one train every three minutes.

Currently, it appears to be about ten fast and two slow.

As someone, who doesn’t like to be on a platform, when a fast train goes through, I believe that some form of advanced safety measures should be installed at Welwyn North station.

It would appear that trains between London Kings Cross and King’s Lynn need to have this specification.

  • Ability to run at 125 mph on the East Coast Main Line
  • Ability to run at 140 mph on the East Coast Main Line, under control of full digital in-cab ERTMS signalling.

This speed increase could reduce the journey time between London Kings Cross and Cambridge to just over half-an-hour with London Kings Cross and King’s Lynn under ninety minutes.

The only new infrastructure needed would be improvements to the Fen Line to King’s Lynn to allow two tph, which I think is needed.

Speed improvements between Hitchin and Cambridge could also benefit timings.

London Kings Cross And Cambridge/Norwich

I believe there is a need for a high speed service between London Kings Cross and Norwich via Cambridge.

  • The Class 755 trains, that are capable of 100 mph take 82 minutes, between Cambridge and Norwich.
  • The electrification gap between Ely and Norwich is 54 miles.
  • Norwich station and South of Ely is fully electrified.
  • Greater Anglia’s Norwich and Cambridge service has been very successful.

With the growth of Cambridge and its incessant need for more space, housing and workers, a high speed train  between London Kings Cross and Norwich via Cambridge could tick a lot of boxes.

  • If hourly, it would double the frequency between Cambridge and Norwich until East-West Rail is completed.
  • All stations between Ely and Norwich get a direct London service.
  • Cambridge would have better links for commuting to the city.
  • London Kings Cross and Cambridge would be less than an hour apart.
  • If the current London Kings Cross and Ely service were to be extended to Norwich, no extra paths on the East Coast Main Line would be needed.
  • Trains could even split and join at Cambridge or Ely to give all stations a two tph service to London Kings Cross.
  • No new infrastructure would be required.

The Cambridge Cruiser would become the Cambridge High Speed Cruiser.

London Paddington And Bedwyn

This Great Western Railway service is run by Class 802 trains.

  • Services run between London Paddington and Bedwyn.
  • Services use the Great Western Main Line at speeds of up to 125 mph.
  • In the future if full digital in-cab ERTMS signalling is implemented, speeds of up to 140 mph could be possible on some sections between London Paddington and Reading.
  • The 13.3 miles between Newbury and Bedwyn is not electrified.

As the service would need to be able to run both ways between Newbury and Bedwyn, a capability to run upwards of perhaps thirty miles without electrification is needed. Currently, diesel power is used, but battery power would be better.

London Paddington And Oxford

This Great Western Railway service is run by Class 802 trains.

  • Services run between London Paddington and Oxford.
  • Services use the Great Western Main Line at speeds of up to 125 mph.
  • In the future if full digital in-cab ERTMS signalling is implemented, speeds of up to 140 mph could be possible on some sections between London Paddington and Didcot Parkway.
  • The 10.3 miles between Didcot Parkway and Oxford is not electrified.

As the service would need to be able to run both ways between Didcot Parkway and Oxford, a capability to run upwards of perhaps thirty miles without electrification is needed. Currently, diesel power is used, but battery power would be better.

Local And Regional Trains On Existing 125 mph Lines

In The UK, in addition to High Speed One and High Speed Two, we have the following lines, where speeds of 125 mph are possible.

  • East Coast Main Line
  • Great Western Main Line
  • Midland Main Line
  • West Coast Main Line

Note.

  1. Long stretches of these routes allow speeds of up to 125 mph.
  2. Full digital in-cab ERTMS signalling is being installed on the East Coast Main Line to allow running up to 140 mph.
  3. Some of these routes have four tracks, with pairs of slow and fast lines, but there are sections with only two tracks.

It is likely, that by the end of the decade large sections of these four 125 mph lines will have been upgraded, to allow faster running.

If you have Hitachi and other trains thundering along at 140 mph, you don’t want dawdlers, at 100 mph or less, on the same tracks.

These are a few examples of slow trains, that use two-track sections of 125 nph lines.

  • East Midlands Railway – 1 tph – Leicester and Lincoln – Uses Midland Main Line
  • East Midlands Railway – 1 tph – Liverpool and Norwich – Uses Midland Main Line
  • Great Western Railway – 1 tph – Cardiff and Portsmouth Harbour – Uses Great Western Main Line
  • Great Western Railway – 1 tph – Cardiff and Taunton – Uses Great Western Main Line
  • Northern – 1 tph – Manchester Airport and Cumbria – Uses West Coast Main Line
  • Northern – 1 tph – Newcastle and Morpeth – Uses East Coast Main Line
  • West Midlands Trains – Some services use West Coast Main Line.

Conflicts can probably be avoided by judicious train planning in some cases, but in some cases trains capable of 125 mph will be needed.

Southeastern Highspeed Services

Class 395 trains have been running Southeastern Highspeed local services since 2009.

  • Services run between London St. Pancras and Kent.
  • Services use Speed One at speeds of up to 140 mph.
  • These services are planned to be extended to Hastings and possibly Eastbourne.

The extension would need the ability to run on the Marshlink Line, which is an electrification gap of 25.4 miles, between Ashford and Ore.

Thameslink

Thameslink is a tricky problem.

These services run on the double-track section of the East Coast Main Line over the Digswell Viaduct.

  • 2 tph – Cambridge and Brighton – Fast train stopping at Hitchin, Stevenage and Finsbury Park.
  • 2 tph – Cambridge and Kings Cross – Slow train stopping at Hitchin, Stevenage, Knebworth, Welwyn North, Welwyn Garden City, Hatfield, Potters Bar and Finsbury Park
  • 2 tph – Peterborough and Horsham – Fast train stopping at Hitchin, Stevenage and Finsbury Park.

Note.

  1. These services are run by Class 700 trains, that are only capable of 100 mph.
  2. The fast services take the fast lines South of the Digswell Viaduct.
  3. South of Finsbury Park, both fast services cross over to access the Canal Tunnel for St, Pancras station.
  4. I am fairly certain, that I have been on InterCity 125 trains running in excess of 100 mph in places between Finsbury Park and Stevenage.

It would appear that the slow Thameslink trains are slowing express services South of Stevenage.

As I indicated earlier, I think it is likely that the Kings Cross and King’s Lynn services will use 125 mph trains for various reasons, like London and Cambridge in well under an hour.

But if 125 mph trains are better for King’s Lynn services, then they would surely improve Thameslink and increase capacity between London and Stevenage.

Looking at average speeds and timings on the 25 miles between Stevenage and Finsbury Park gives the following.

  • 100 mph – 15 minutes
  • 110 mph – 14 minutes
  • 125 mph – 12 minutes
  • 140 mph – 11 minutes

The figures don’t appear to indicate large savings, but when you take into account that the four tph running the Thameslink services to Peterborough and Cambridge stop at Finsbury Park and Stevenage and have to get up to speed, I feel that the 100 mph Class 700 trains are a hindrance to more and faster trains on the Southern section of the East Coast Main Line.

It should be noted, that faster trains on these Thameslink services would probably have better acceleration and and would be able to execute faster stops at stations.

There is a similar less serious problem on the Midland Main Line branch of Thameslink, in that some Thameslink services use the fast lines.

A couple of years ago, I had a very interesting chat with a group of East Midlands Railway drivers. They felt that the 100 mph Thameslink and the 125 mph Class 222 trains were not a good mix.

The Midland Main Line services are also becoming more complicated, with the new EMR Electric services between St. Pancras and Corby, which will be run by 110 mph Class 360 trains.

Hitachi’s Three Trains With Batteries

Hitachi have so far announced three battery-electric trains. Two are based on battery packs being developed and built by Hyperdrive Innovation.

Hyperdrive Innovation

Looking at the Hyperdrive Innovation web site, I like what I see.

Hyperdrive Innovation provided the battery packs for JCB’s first electric excavator.

Note that JCB give a five-year warranty on the Hyperdrive batteries.

Hyperdrive have also been involved in the design of battery packs for aircraft push-back tractors.

The battery capacity for one of these is given as 172 kWh and it is able to supply 34 kW.

I was very surprised that Hitachi didn’t go back to Japan for their batteries, but after reading Hyperdrive’s web site about the JCB and Textron applications, there would appear to be good reasons to use Hyperdrive.

  • Hyperdrive have experience of large lithium ion batteries.
  • Hyperdrive have a design, develop and manufacture model.
  • They seem to able to develop solutions quickly and successfully.
  • Battery packs for the UK and Europe are made in Sunderland.
  • Hyperdrive are co-operating with Nissan, Warwick Manufacturing Group and Newcastle University.
  • They appear from the web site to be experts in the field of battery management, which is important in prolonging battery life.
  • Hyperdrive have a Taiwanese partner, who manufactures their battery packs for Taiwan and China.
  • I have done calculations based on the datasheet for their batteries and Hyperdrive’s energy density is up with the best

I suspect, that Hitachi also like the idea of a local supplier, as it could be helpful in the negotiation of innovative applications. Face-to-face discussions are easier, when you’re only thirty miles apart.

Hitachi Regional Battery Train

The first train to be announced was the Hitachi Regional Battery Train, which is described in this Hitachi infographic.

Note.

  1. It is only a 100 mph train.
  2. The batteries are to be designed and manufactured by Hyperdrive Innovation.
  3. It has a range of 56 miles on battery power.
  4. Any of Hitachi’s A Train family like Class 800, 802 or 385 train can be converted to a Regional Battery Train.

No orders have been announced yet.

But it would surely be very suitable for routes like.

  • London Paddington And Bedwyn
  • London Paddington And Oxford

It would also be very suitable for extensions to electrified suburban routes like.

  • London Bridge and Uckfield
  • London Waterloo and Salisbury
  • Manchester Airport and Windermere.
  • Newcastle and Carlisle

It would also be a very sound choice to extend electrified routes in Scotland, which are currently run by Class 385 trains.

Hitachi InterCity Tri-Mode Battery Train

The second train to be announced was the Hitachi InterCity Tri-Mode Battery Train, which is described in this Hitachi infographic.

Note.

  1. Only one engine is replaced by a battery.
  2. The batteries are to be designed and manufactured by Hyperdrive Innovation.
  3. Typically a five-car Class 800 or 802 train has three diesel engines and a nine-car train has five.
  4. These trains would obviously be capable of 125 mph on electrified main lines and 140 mph on lines fully equipped with digital in-cab ERTMS signalling.

Nothing is said about battery range away from electrification.

Routes currently run from London with a section without electrification at the other end include.

  • London Kings Cross And Harrogate – 18.3 miles
  • London Kings Cross And Hull – 36 miles
  • London Kings Cross And Lincoln – 16.5 miles
  • London Paddington And Bedwyn – 13.3 miles
  • London Paddington And Oxford – 10.3 miles

In the March 2021 Edition of Modern Railways, LNER are quoted as having aspirations to extend the Lincoln service to Cleethorpes.

  • With all energy developments in North Lincolnshire, this is probably a good idea.
  • Services could also call at Market Rasen and Grimsby.
  • Two trains per day, would probably be a minimum frequency.

But the trains would need to be able to run around 64 miles each way without electrification. Very large batteries and/or charging at Cleethorpes will be needed.

Class 803 Trains For East Coast Trains

East Coast Trains have ordered a fleet of five Class 803 trains.

  • These trains appear to be built for speed and fast acceleration.
  • They have no diesel engines, which must save weight and servicing costs.
  • But they will be fitted with batteries for emergency power to maintain onboard  train services in the event of overhead line failure.
  • They are planned to enter service in October 2021.

Given that Hyperdrive Innovation are developing traction batteries for the other two Hitachi battery trains, I would not be the least bit surprised if Hyperdrive were designing and building the batteries for the Class 803 trains.

  • Hyperdrive batteries are modular, so for a smaller battery you would use less modules.
  • If all coaches are wired for a diesel engine, then they can accept any power module like a battery or hydrogen pack, without expensive redesign.
  • I suspect too, that the battery packs for the Class 803 trains could be tested on an LNER Class 801 train.

LNER might also decide to replace the diesel engines on their Class 801 trains with an emergency battery pack, if it were more energy efficient and had a lighter weight.

Thoughts On The Design Of The Hyperdrive innovation Battery Packs

Consider.

  • Hitachi trains have a sophisticated computer system, which on start-up can determine the configuration of the train or whether it is more than one train running as a longer formation or even being hauled by a locomotive.
  • To convert a bi-mode Class 800 train to an all-electric Class 801 the diesel engines are removed. I suspect that the computer is also adjusted, but train formation may well be totally automatic and independent of the driver.
  • Hyperdrive Innovation’s battery seem to be based on a modular system, where typical modules have a capacity of 5 kWh, weighs 32 Kg and has a volume of 0.022 cu metres.
  • The wet mass of an MTU 16V 1600 R80L diesel engine commonly fitted to AT-300 trains of different types is 6750 Kg or nearly seven tonnes.
  • The diesel engine has a physical size of 1.5 x 1.25 x 0.845 metres, which is a volume of 1.6 cubic metres.
  • In How Much Power Is Needed To Run A Train At 125 mph?, I calculated that a five-car Class 801 electric train, needed 3.42 kWh per vehicle-mile to maintain 125 mph.
  • It is likely, than any design of battery pack, will handle the regenerative braking.

To my mind, the ideal solution would be a plug compatible battery pack, that the train’s computer thought was a diesel engine.

But then I have form in the area of plug-compatible electronics.

At the age of sixteen, for a vacation job, I worked in the Electronics Laboratory at Enfield Rolling Mills.

It was the early sixties and one of their tasks was at the time replacing electronic valve-based automation systems with new transistor-based systems.

The new equipment had to be compatible to that which it replaced, but as some were installed in dozens of places around the works, they had to be able to be plug-compatible, so that they could be quickly changed. Occasionally, the new ones suffered infant-mortality and the old equipment could just be plugged back in, if there wasn’t a spare of the new equipment.

So will Hyperdrive Innovation’s battery-packs have the same characteristics as the diesel engines that they replace?

  • Same instantaneous and continuous power output.
  • Both would fit the same mountings under the train.
  • Same control and electrical power connections.
  • Compatibility with the trains control computer.

I think they will as it will give several advantages.

  • The changeover between diesel engine and battery pack could be designed as a simple overnight operation.
  • Operators can mix-and-match the number of diesel engines and battery-packs to a given route.
  • As the lithium-ion cells making up the battery pack improve, battery capacity and performance can be increased.
  • If the computer, is well-programmed, it could reduce diesel usage and carbon-emissions.
  • Driver conversion from a standard train to one equipped with batteries, would surely be simplified.

As with the diesel engines, all battery packs could be substantially the same across all of Hitachi’s Class 80x trains.

What Size Of Battery Would Be Possible?

If Hyperdrive are producing a battery pack with the same volume as the diesel engine it replaced, I estimate that the battery would have a capacity defined by.

5 * 1.6 / 0.022 = 364 kWh

In an article in the October 2017 Edition of Modern Railways, which is entitled Celling England By The Pound, Ian Walmsley says this in relation to trains running on the Uckfield Branch, which is not very challenging.

A modern EMU needs between 3 and 5 kWh per vehicle mile for this sort of service.

As a figure of 3.42 kWh per vehicle-mile to maintain 125 mph, applies to a Class 801 train, I suspect that a figure of 3 kWh or less could apply to a five-car Class 800 train trundling at around 80-100 mph to Bedwyn, Cleethorpes or Oxford.

  • A one-battery five-car train would have a range of 24.3 miles
  • A two-battery five-car train would have a range of 48.6 miles
  • A three-battery five-car train would have a range of 72.9 miles

Note.

  1. Reducing the consumption to 2.5 kWh per vehicle-mile would give a range of 87.3 miles.
  2. Reducing the consumption to 2 kWh per vehicle-mile would give a range of 109.2 miles.
  3. Hitachi will be working to reduce the electricity consumption of the trains.
  4. There will also be losses at each station stop, as regenerative braking is not 100 % efficient.

But it does appear to me, that distances of the order of 60-70 miles would be possible on a lot of routes.

Bedwyn, Harrogate, Lincoln and Oxford may be possible without charging before the return trip.

Cleethorpes and Hull would need a battery charge before return.

A Specification For A High Speed Metro Train

I have called the proposed train a High Speed Metro Train, as it would run at up to 140 mph on an existing high speed line and then run a full or limited stopping service to the final destination.

These are a few thoughts.

Electrification

In some cases like London Kings Cross and King’s Lynn, the route is already electrified and batteries would only be needed for the following.

  • Handling regenerative braking.
  • Emergency  power in case of overhead line failure.
  • Train movements in depots.

But if the overhead wires on a branch line. are in need of replacement, why not remove them and use battery power? It might be the most affordable and least disruptive option to update the power supply on a route.

The trains would have to be able to run on both types of electrification in the UK.

  • 25 KVAC overhead.
  • 750 VDC third rail.

This dual-voltage capability would enable the extension of Southeastern Highspeed services.

Operating Speed

The trains must obviously be capable of running at the maximum operating speed on the routes they travel.

  • 125 mph on high speed lines, where this speed is possible.
  • 140 mph on high speed lines equipped with full digital in-cab ERTMS signalling, where this speed is possible.

The performance on battery power must be matched with the routes.

Hitachi have said, that their Regional Battery trains can run at up to 100 mph, which would probably be sufficient for most secondary routes in the UK and in line with modern diesel and electric multiple units.

Full Digital In-cab ERTMS Signalling

This will be essential and is already fitted to some of Hitachi’s trains.

Regenerative Braking To Batteries

Hitachi’s battery electric  trains will probably use regenerative braking to the batteries, as it is much more energy efficient.

It also means that when stopping at a station perhaps as much as 70-80% of the train’s kinetic energy can be captured in the batteries and used to accelerate the train.

In Kinetic Energy Of A Five-Car Class 801 Train, I showed that at 125 mph the energy of a full five-car train is just over 100 kWh, so batteries would not need to be unduly large.

Acceleration

This graph from Eversholt Rail, shows the acceleration and deceleration of a five-car Class 802 electric train.

As batteries are just a different source of electric power, I would think, that with respect to acceleration and deceleration, that the performance of a battery-electric version will be similar.

Although, it will only achieve 160 kph instead of the 200 kph of the electric train.

I estimate from this graph, that a battery-electric train would take around 220 seconds from starting to decelerate for a station to being back at 160 kph. If the train was stopped for around eighty seconds, a station stop would add five minutes to the journey time.

London Kings Cross And Cleethorpes

As an example consider a service between London Kings Cross and Cleethorpes.

  • The section without electrification between Newark and Cleethorpes is 64 miles.
  • There appear to be ambitions to increase the operating speed to 90 mph.
  • Local trains seem to travel at around 45 mph including stops.
  • A fast service between London Kings Cross and Cleethorpes would probably stop at Lincoln Central, Market Rasen and Grimsby Town.
  • In addition, local services stop at Collingham, Hykeham, Barnetby and Habrough.
  • London Kings Cross and Newark takes one hour and twenty minutes.
  • London Kings Cross and Cleethorpes takes three hours and fifteen minutes with a change at Doncaster.

I can now calculate a time between Kings Cross and Cleethorpes.

  • If a battery-electric train can average 70 mph between Newark and Cleethorpes, it would take 55 minutes.
  • Add five minutes for each of the three stops at Lincoln Central, Market Rasen and Grimsby Town
  • Add in the eighty minutes between London Kings Cross and Newark and that would be  two-and-a-half hours.

That would be very marketing friendly and a very good start.

Note.

  1. An average speed of 80 mph would save seven minutes.
  2. An average speed of 90 mph would save twelve minutes.
  3. I suspect that the current bi-modes would be slower by a few minutes as their acceleration is not as potent of that of an electric train.

I have a feeling London Kings Cross and Cleethorpes via Lincoln Central, Market Rasen and Grimsby Town, could be a very important service for LNER.

Interiors

I can see a new lightweight and more energy efficient interior being developed for these trains.

In addition some of the routes, where they could be used are popular with cyclists and the current Hitachi trains are not the best for bicycles.

Battery Charging

Range On Batteries

I have left this to last, as it depends on so many factors, including the route and the quality of the driving or the Automatic Train Control

Earlier, I estimated that a five-car train with all three diesel engines replaced by batteries, when trundling around Lincolnshire, Oxfordshire or Wiltshire could have range of up to 100 miles.

That sort of distance would be very useful and would include.

  • Ely and Norwich
  • Newark and Cleethorpes
  • Salisbury and Exeter

It might even allow a round trip between the East Coast Main Line and Hull.

The Ultimate Battery Train

This press release from Hitachi is entitled Hitachi And Eversholt Rail To Develop GWR Intercity Battery Hybrid Train – Offering Fuel Savings Of More Than 20%.

This is a paragraph.

The projected improvements in battery technology – particularly in power output and charge – create opportunities to replace incrementally more diesel engines on long distance trains. With the ambition to create a fully electric-battery intercity train – that can travel the full journey between London and Penzance – by the late 2040s, in line with the UK’s 2050 net zero emissions target.

Consider.

  • Three batteries would on my calculations give a hundred mile range.
  • Would a train with no diesel engines mean that fuel tanks, radiators and other gubbins could be removed and more or large batteries could be added.
  • Could smaller batteries be added to the two driving cars?
  • By 2030, let alone 2040, battery energy density will have increased.

I suspect that one way or another these trains could have a range on battery power of between 130 and 140 miles.

This would certainly be handy in Scotland for the two routes to the North.

  • Haymarket and Aberdeen, which is 130 miles without electrification.
  • Stirling and Inverness, which is 111 miles without electrification, if the current wires are extended from Stirling to Perth, which is being considered by the Scottish Government.

The various sections of the London Paddington to Penzance route are as follows.

  • Paddington and Newbury – 53 miles – electrified
  • Newbury and Taunton – 90 miles – not electrified
  • Taunton and Exeter – 31 miles – not electrified
  • Exeter and Plymouth – 52 miles – not electrified
  • Plymouth and Penzance – 79 miles – not electrified

The total length of the section without electrification between Penzance and Newbury  is a distance of 252 miles.

This means that the train will need a battery charge en route.

I think there are three possibilities.

  • Trains can take up to seven minutes for a stop at Plymouth. As London and Plymouth trains will need to recharge at Plymouth before returning to London, Plymouth station could be fitted with comprehensive recharge facilities for all trains passing through. Perhaps the ideal solution would be to electrify all lines and platforms at Plymouth.
  • Between Taunton and Exeter, the rail line runs alongside the M5 motorway. This would surely be an ideal section to electrify, as it would enable battery electric trains to run between Exeter and both Newbury and Bristol.
  • As some trains terminate at Exeter, there would probably need to be charging facilities there.

I believe that the date of the late 2040s is being overly pessimistic.

I suspect that by 2040 we’ll be seeing trains between London and Aberdeen, Inverness and Penzance doing the trips without a drop of diesel.

But Hitachi are making a promise of London and Penzance by zero-carbon trains, by the late-2040s, because they know they can keep it.

And Passengers and the Government won’t mind the trains being early!

Conclusion

This could be a very useful train to add to Hitachi’s product line.

Approaching Kings Cross – 6th January 2021

I took these pictures approaching Kings Cross.

Note.

  1. There is still track to be laid.
  2. The electrification is still to be erected.

But everything seems to be getting there.

This Google Map shows the section between the two tunnels.

Both tunnels have three double-track bores, where in this massive project, the Eastern bores are being brought back into use to add capacity to Kings Cross station.

Note.

  1. The East Coast Main Line runs North-South across the map.
  2. The quadruple track crossing East-West at the top of the map is the North London Line.
  3. Below it, is the Channel Tunnel Rail Link into |St. Pancras.
  4. The link to the Canal Tunnels take Thameslink trains to the deep level platforms in St. Pancras.
  5. The two new tracks will be on the Eastern side of the East Coast Main Line.

This second Google Map shows the track and platform layout at Kings Cross station.

Note.

  1. There are twelve platforms, which are numbered from 0 to 11, with Platform 0 in the East.
  2. The various islands are numbered as follows from East to West; 0/1, 2/3, 4/5, 6/7, 8/9 and 10/11.
  3. The six tracks through the tunnels may be bi-directional, so will each track be linked to a pair of platforms?
  4. Platforms 0 to 4 are in the Eastern half of the station
  5. Platforms 5 to 0 are in the Western half of the station
  6. Platforms 9, 10 and 11 are short platforms  in the old suburban station, which is mainly used by suburban services to Cambridge and Kings Lynn.

When I arrived there was a five-car Azuma in Platform 9, as these pictures show.

I’ve seen Grand Central’s Class 180 trains in these short platforms before, so is this going to be a regular occurrence.

Services Into Kings Cross

When the remodelling at Kings Cross is complete, current plans say the following trains will be running into Kings Cross station.

  • LNER – Two tph – Edinburgh – Long train
  • LNER – Two tph – Leeds – Long train
  • LNER – One tph – Lincoln or York – Long or short train
  • Great Northern – Two tph – Cambridge (stopping) – Short train
  • Great Northern – Two tph – Cambridge (fast) – Short train
  • Hull trains – Seven tpd – Hull and Beverley – Short train
  • East Coast Trains – Five tpd – Edinburgh – Short train
  • Grand Central – Four tpd – Bradford Interchange – Long or short train
  • Grand Central – Five tpd – Sunderland – Long or short train

Note,

  1. tph is trains per hour and tpd is trains per day.
  2. There is a mixture of short and long trains.
  3. Short trains can fit all platforms, but long trains can only use platforms 0-8.
  4. There are nine tph and a total of 21 tpd in various less-frequent services.

My scheduling experience in other fields, says that ten platforms will be needed for a full service, with each of the ten platforms handling just one tph.

Conclusion

Wjen all the work is completed, Kings Cross station will have room for a few extra trains.

The Flexible Train For A Pandemic

Anybody, who believes that COVID-19  will be the last pandemic is an idiot!

The virus has shown, those with evil intentions to take over the world, that a pandemic, started by a weaponised virus, whether natural or man-made, can be a useful tool in your arsenal.

We must prepare for the next pandemic.

So how will we travel by train?

Current Train Interiors And The Need To Social Distance

The need to social distance will remain paramount and some of our current train interiors are better than others for passengers to remain two metres apart.

These are some typical UK train interiors.

Typical London Overground Interior

These pictures show a typical London Overground interior on their Class 378 trains and Class 710 trains.

Distancing at two-metres will reduce the capacity dramatically, but with wide doors and common sense, this layout could allow social distancing to work.

Siemens Desiro City Suburban Interior

These pictures show the interior of the two Siemens Desiro City fleets; Thameslink‘s Class 700 trains, Great Northern‘s Class 717 trains and South Western Railway‘s Class 707 trains.

As with the London Overground layout, as the trains are fairly spacious with wide doors, social distancing could probably be made to work at reduced capacity.

Four Seats And A Table

These pictures show a selection of trains, where you have four seats around a table.

Trains include Greater Anglia’s Class 379 trains, Class 745 trains, Class 755 trains, and a selection of Class 800 trains, Class 377 trains from various operators and a superb reconditioned Class 150 train from Great Western Railway.

Could these be made to work, if there was only one person or self-isolating group living together at each set of four seats?

Designing For A Pandemic

These are my thoughts on various topics.

Seating Layouts

Consider.

  • As the pictures show, maintaining social distancing will be difficult on some trains.
  • Could the number of seats in use, be determined by the avert level of the pandemic?
  • Could seats have lights on them to show their status?
  • Will companies insist on reservations?

As to the last point, some train companies are already doing this!

 

Luggage

Will there be limits on the luggage you can take?

Entering And Leaving The Train

Would someone with a dangerous infectious disease be more likely to pass it on, when entering or leaving a train, through a narrow doorway?

I believe coaches with narrow single end doors make social distancing impossible.

  • Passengers get stuck in the bottleneck that these doors create.
  • Passengers are entering and leaving through the same crowded door.
  • Anybody in a wheelchair, pushing a child in a buggy or dragging a large suitcase, will make the bottleneck worse.

They are not fit for purpose in a post-COVID-19 world!

It might be possible to make the doors work using a traffic light system, which allowed passengers to leave, before any passengers were allowed to enter.

But any safe system, would be likely to increase dwell times in stations.

These pictures show the doors and entry and exit for Greater Anglia’s Class 745 and Class 755 trains.

These trains have been designed to be able to run London and Norwich services over a distance of more than a hundred miles, so the trains could be considered InterCity services in all but name.

Note.

  1. All doors are double and lead into a wide and spacious lobby.
  2. Entry and exit is level, as there is a gap filler between train and platform.
  3. Entry and exit in a wheelchair, pushing a buggy or wheeling a large suitcase doesn’t

Greater Anglia’s new trains would appear to be better in a post-COVID-19 world.

I also think, that these trains are better designed for the disabled, those with young children, and the elderly and just plain worn-out.

Finding A Seat

If you watch people entering a train, they often take forever to find their seat and sit down. Especially, if they’ve got a massive suitcase that won’t fit in the space provided.

Rules on boarding a train and how much luggage you can bring will be developed.

Toilets

Will visiting the toilet still be allowed? Or will toilets even be removed?

Flexibility

I think a degree of flexibility must be built into the design.

I mentioned lights on seats to show which could be used, that could be lit up according to the threat level.

Conclusion

Travelling will get more complicated.

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!

Up To £3 Billion For Crossrail To Ebbsfleet

The title of this post, is the same as that of an article in the July 2019 Edition of Modern Railways.

This is an extract.

Current estimates gave a cost range of between £1.3 billion and £3 billion, which Mr. Williams said depended on whether services shared tracks with existing Southeastern services east of Abbey Wood or had their own segregated tracks.

Mr. Williams is Transport for London’s Direct of City  Planning; Alex Williams.

This Google Map shows Northfleet and Ebbsfleet stations.

Note.

  1. The large Ebbsfleet International station towards the bottom of the map.
  2. Northfleet station on the North Kent Line in the North East corner of the map.
  3. The two stations are about five hundred  metres apart as the  crow flies.

There has been a lot of pressure in the past to build a pedestrian link between the two stations, as reported by the Wikipedia entry for Northfleet station.

The station is very close to Ebbsfleet International station (the NNE entrance is only 334 yards (305 m) from Northfleet’s station), but passengers (using public transport) will find it far easier to access Ebbsfleet International from Gravesend or Greenhithe, as these stations are more accessible and offer easy access to Fastrack bus services. The walking route between the two stations is 0.6 miles (1 km) or 0.8 miles (1.3 km) and a suitable pedestrian link has not been built because of funding issues and objections from Land Securities.

Why when Ebbsfleet International station was built in the early 2000s for opening in 2007, was a pedestrian link not built between the two stations?

How much did omitting the link save?

Luton Airport are building the Luton DART, which is a people mover to  connect Luton Airport Parkway station with the airport.

  • It is 1.4 miles long.
  • It is fully automated.
  • It might have an extra station serving the mid-stay parking.
  • It appears to be taking three years to build.

All of this very comprehensive system appears to be costing around £200 million.

I doubt that a simple pedestrian link, like a bridge with travelators,  would have cost more than a few tens of million pounds.

To me, it is one of the great mysteries of the building of the Channel Tunnel Rail Link, that this pedestrian link wasn’t built.

I think, in future, we could come to regret that it wasn’t built along with the rest of Ebbsfleet International station in the early 2000s.

The extension of Crossrail to Ebbsfleet is about the following.

  • Creating a high-frequency railway to serve all the new housing developments in the Thames Gateway and along the South Bank of the Thames.
  • Connecting  Ebbsfleet International station and other developments around the station to Crossrail.

In some ways, these two objectives are incompatible.

  • To serve the housing developments along the river, the Crossrail extension needs to run roughly along the route of the North Kent Line.
  • To serve Ebbsfleet International station, the route needs to be further inland.

Choosing either route is going to annoy people who live on the other.

For this reason, I feel we need a good old-fashioned British compromise or some very-radical thinking.

Current Services Along The North Kent Line

I shall start by looking at current services on the North Kent Line.

Thameslink – Luton And Rainham (Kent)

A Thameslink service

  • Two trains per hour (tph)
  • South of the Thames, the service calls at London Bridge, Deptford, Greenwich, Maze Hill, Whatcombe Park, Charlton, Woolwich Arsenal, Plumstead, Abbey Wood, Slade Green, Dartford, Stone Crossing, Greenhithe for Bluewater, Swanscombe, Northfleet, Gravesend, Higham, Strood, Rochester, Chatham and Gillingham.
  • Eight-car Class 700 trains work the route, which have a 100 mph operating speed.
  • The service calls at Northfleet for a possible interchange with services running from Ebbsfleet International station
  • The service calls at Abbey Wood for interchange with Crossrail.

If there needed to be more capacity on this service, I suspect Thameslink could run twelve-car trains.

Southeastern – London Charing Cross And Gravesend

A Southeastern Metro service.

  • Two tph
  • Calls at Waterloo East, London Bridge, New Eltham, Sidcup, Bexley, Crayford, Dartford, Stone Crossing, Greenhithe for Bluewater, Swanscombe and Northfleet
  • The service calls at Northfleet for a possible interchange with services running from Ebbsfleet International station.
  • The service calls at Gravesend for interchange with Southeastern HighSpeed services between St. Pancras International station and North-East Kent, East Kent and soon-to-be East Sussex.
  • Class 465 trains work the route, which have a 75 mph operating speed.

This picture shows a train for Gravesend in London Bridge station.

My feeling, is that the service would be improved by modern 100 mph trains, as these antique slow-coaches must restrict the speed of faster trains.

Southeastern – London Cannon Street And Dartford Loop Line

A Southeastern Metro service.

  • Four tph in both directions.
  • Calls at London Bridge, Deptford, Greenwich, Maze Hill, Westcombe Park, Charlton, Woolwich Dockyard, Woolwich Arsenal, Plumstead, Abbey Wood, Belvedere, Erith and Slade Green.
  • Two tph return to Cannon Street via Crayford and Sidcup and two tph return to Cannon Street via Barnehurst and Bexleyheath.
  • The service calls at Abbey Wood for a planned interchange with Crossrail.
  • Class 465 trains work the route.

As I said with the previous service, these 75 mph trains need replacing with 100 mph trains.

Southeastern – London Charing Cross And Dartford

A Southeastern Metro service.

  • Two tph
  • Calls at Waterloo East, London Bridge, Lewisham, Blackheath, Charlton, Woolwich Dockyard, Woolwich Arsenal, Plumstead, Abbey Wood, Belvedere, Erith and Slade Green.
  • The service calls at Abbey Wood for a planned interchange with Crossrail.
  • Class 465 trains work the route.

As I said with the two previous services, these 75 mph trains need replacing with 100 mph trains.

Southeastern – London Victoria And Dover

A Southeastern Mainline service.

  • Two tph
  • Calls on the North Kent Line at Rochester, Chatham, Gillingham and Rainham.
  • Class 465 trains work the route.

As I said with previous services, these 75 mph trains need replacing with 100 mph trains.

Southeastern – London Victoria And Ramsgate

A Southeastern Mainline service.

  • One tph
  • Calls on the North Kent Line at Rochester, Chatham, Gillingham and Rainham.
  • Class 465 trains work the route.

As I said with previous services, these 75 mph trains need replacing with 100 mph trains.

Southeastern – London St. Pancras And Faversham

A Southeastern HighSpeed service.

  • One tph
  • Calls at Stratford International, Ebbsfleet International, Gravesend, Strood, Rochester, Chatham, Gillingham, Rainham and Sittingbourne.
  • The service calls at Ebbsfleet International for an interchange with Continental services.
  • Class 395 trains work the route, which have a 100 mph operating speed on lines electrified using a third-rail.

This picture shows a Class 395 train at Gravesend station.

East of Ebbsfleet International, this service can be considered a 100 mph local train, that gets slowed by the 75 mph services.

Southeastern – London St Pancras International Loop Service

A Southeastern HighSpeed service.

  • One tph
  • Calls at Stratford International, Ebbsfleet International, Gravesend, Strood, Rochester, Chatham, Gillingham, Rainham, Sittingbourne, Faversham, Whitstable, Herne Bay, Birchington-on-Sea, Margate, Broadstairs, Ramsgate, Sandwich, Deal, Walmer, Martin Mill, Dover Priory, Folkestone Central, Folkestone West, Ashord International, Ebbsfleet International and Stratford International.
  • The service calls at Ebbsfleet International and Ashford International for an interchange with Continental services.
  • Class 395 trains work the route.

East of Ebbslfleet International, this service can be considered a 100 mph local train, that gets slowed by the 75 mph services.

Southeastern – London St Pancras International And Ramsgate

A Southeastern HighSpeed service.

  • One tph
  • Calls at Stratford International, Ebbsfleet International, Ashford International, Canterbury West, Ramsgate and Broadstairs
  • The service calls at Ebbsfleet International and Ashford International for an interchange with Continental services.
  • Class 395 trains work the route.

East of Ashford International, this service can be considered a 100 mph local train, that gets slowed by the 75 mph services.

A Summary Of Services By Station

I will look at the current number of trains at stations between London Bridge and Faversham.

  • Deptford – 6 tph
  • Greenwich – 6 tph
  • Maze Hill – 6 tph
  • Westcombe Park – 6 tph
  • Charlton – 8 tph
  • Woolwich Dockyard – 6 tph
  • Woolwich Arsenal – 8 tph
  • Plumstead – 8 tph
  • Abbey Wood – 8 tph
  • Belvedere – 6 tph
  • Erith – 6 tph
  • Slade Green – 6 tph
  • Dartford – 12 tph to London and 6 tph to the East
  • Stone Crossing – 4 tph
  • Greenhithe for Bluewater – 6 tph
  • Swanscombe – 4 tph
  • Northfleet – 4 tph
  • Gravesend – 6 tph to London and 5 tph to the East
  • Higham – 2 tph
  • Strood – 4 tph
  • Rochester – 7 tph
  • Chatham – 7 tph
  • Gillingham – 7 tph
  • Rainham – 7 tph to London and 5 tph to the East
  • Sittingbourne – 5 tph
  • Faversham – 5 tph

This is almost a train every ten minutes all the way from London to Faversham.

In addition Ebbsfleet International has four tph to and from London St. Pancras International.

Could Extra Services Be Run Along The North Kent Line?

Consider.

  • Six tph is not a high frequency for a relatively simple route like this.
  • The East London Line, which has about the same level of complication easily handles sixteen tph and it is planned to go to twenty tph in the next couple of years.
  • Digital signalling and Automatic Train Control will handle twenty-four tph on Crossrail and Thameslink.
  • Freight trains do not run at a high frequency on the route.

I wouldn’t be surprised to see another eight-ten tph added to the route.

How Many Trains Should Terminate At Ebbsfleet?

Currently, Crossrail has six fully-planned and built terminals.

  • Abbey Wood will handle twelve tph in the Peak and ten tph in the Off Peak
  • Heathrow Terminal 4 will handle four tph all day
  • Heathrow Terminal 5 will handle two tph all day
  • Maidenhead will handle two tph all day.
  • Reading will handle four tph in the Peak and two tph in the Off Peak
  • Shenfield will handle twelve tph in the Peak and ten tph in the Off Peak

It would appear that most terminals only handle between two and four tph.

I very much suspect, that research will show that four tph to and from Ebbsfleet will be sufficient.

It certainly meets the requirement for a Turn-Up-And-Go service, as used by London Overground and Merseyrail.

Possible Terminals For Crossrail In Kent

Wikipedia gives services to Abbey Wood station under Services as follows.

  • Peak – Twelve tph
  • Off Peak – Ten tph

There are several possible terminals for Crossail in Kent

Gravesend Station

When Crossrail was planned, the route was safeguarded to Gravesend station, with a depot at Hoo Junction to the East.

This section in Wikipedia, which is entitled To Gravesend And Hoo Junction, gives more details. This is the first sentence.

The route to Gravesend has been safeguarded by the Department for Transport, although it was made clear that as at February 2008 there was no plan to extend Crossrail beyond the then-current scheme.

These pictures show Gravesend station.

The station is well-appointed and has good services.

  • The station is close to the Town Centre.
  • It is step-free.
  • There is a West-facing bay platform, which is currently used for a two tph service to Charing Cross.
  • The platforms are very long.
  • HighSpeed commuter services and Thameslink call at the station.

Crossrail services could either terminate in the bay platform or run through the station to a turnback siding at Hoo Junction.

Either way, I’m sure four tph could be easily handled.

Ebbsfleet International Station

Ebbsfleet International station is named in the title of this post and many are expecting that Crossrail will be extended to the station.

This Google Map shows this station.

Note.

  1. The High Speed platforms 1 to 4, for St. Pancras, Ashford International and the Continent are to the left.
  2. The two separate platforms 5 and 6 for high-speed services to and from North Kent.
  3. The large amount of car parking around the station.

It’s not obvious, where a platform or two for Crossrail could fit in.

The Wikipedia entry for Ebbsfleet International station, says this about Crossrail.

It was formerly planned that Crossrail would terminate at a separate station between Northfleet and Ebbsfleet International but under the current plan, Abbey Wood further west will be the eastern terminus. However, a Crossrail extension from Abbey Wood to Gravesend (Hoo Junction) remains safeguarded

Perhaps, Crossrail platforms could be on the Northfleet side of the station, to the North of platforms 5 and 6.

If two platforms are good enough for Abbey Wood station, then surely, two platforms would be sufficient at Ebbsfleet International station.

This Google Map shows where the North Kent Line rrosses the Channel Tunnel Rail Link about five hundred metres North of Ebbsfleet station.

Could a flyover or dive-under be created to create a spur from the North Kent Line, that would allow Crossrail trains to sneak down the Eastern side of the high speed lines to platforms, alongside the current Platforms 5 and 6?

This picture was taken from a train on the bridge that carries the North Kent Line over the high speed lines.

I suspect there is a solution in there somewhere.

One interesting possibility could be for the Crossrail trains to share Platforms 5 and 6 at Ebbsfleet International station with the HighSpeed commuter services to North Kent.

This picture shows the flying junction, where the tracks through Platforms 5 and 6, join the North Kent Line between Northfleet and Gravesend stations.

As currently, only two tph use the link, surely, Crossrail services of four tph could share, if they were to go through Ebbsfleet International and terminate at Gravesend?

I’m not an expert on designing bridges, but to my untrained eye, a flyover to connect the Ebbsfleet loop to the North Kent Line to the West of the station, wouldn’t be much more complicated, than the flyover to the East.

I think, a loop to serve Ebbsfleet would have other advantages.

  • Crossrail would have access to a much-needed Park-and-Ride site.
  • The interchange between Crossrail and Continental services would be a short walk.
  • Probably only minimal improvements would be needed to Ebbsfleet International station.
  • There would be a same-platform interchange between Crossrail and HighSpeed commuter services to and from St. Pancras.
  • Construction would be more affordable and less disruptive.

Perhaps, it’s a better idea, than I originally thought?

Abbey Wood

Abbey Wood station has been designed to handle twelve tph.

The picture shows the four platforms at Abbey Wood station with a Class 345 train in one of the two Crossrail platforms.

  • Two platforms can handle twelve tph.
  • A turnback facility that has been built at the station to handle more trains or service recovery.
  • There are three bridges, two escalators and at least two lifts to facilitate transfer between Crossrail and other services.
  • Platforms are spacious.
  • There is a wide gate line controlling entry to the station.
  • The station is well-served by buses, but car parking is limited.

It is one of the better new stations and would certainly have no problems handling the eight tph, it would need to in the Peak, if four tph, carried on to terminate at Ebbsfleet.

Dartford Station

Dartford station probably has claims to be terminal for Crossrail.

It is a large town, clustered around the station.

There is a lot of new housing close to the station.

It has regularly services to several London terminals, by a variety of routes.

But it appears to be a very cramped station with narrow platforms, as some of these pictures shows.

Services at the station include.

  • Eight tph – Charing Cross
  • Two tph – Victoria
  • Four tph – Gravesend

Thameslink also run two tph between Luton and Rainham.

It is much-more a station where travellers change trains, than one where services terminate..

But even for that it needs improvement.

My Preferred Crossrail Option

I would extend Crossrail to Ebbsfleet in a simple manner, that was capable of being expanded, as traffic needs changed in the future.

Four tph Would Continue Through Abbey Wood Station

I feel that a Turn-Up-And-Go service between Abbey Wood and Ebbsfleet, of four tph would be sufficient, especially if other services on the route, were to be increased in frequency and capacity.

Services Would Terminate At Gravesend Station

The original safeguarded plan for Crossrail to be extended to Gravesend, with a depot at Hoo Junction, is in my mind a good plan.

  • Gravesend station is probably Crossrail-ready.
  • Gravesend station could handle the turnround of Crossrail running at a frequency of four tph.
  • There is plenty of space for a depot at Hoo Junction.

But perhaps most importantly,, it is the original plan suggested in the original design of Crossrail.

Have decisions been made by the various councils on the extended route, based on this plan?

Crossrail Services Would Use The North Kent Line

The extended Crossrail service would call at Belvedere, Erith, Slade Green, Dartford, Stone Crossing, Greenhithe for Bluewater, Swanscombe and Northfleet.

Frequencies of trains at the stations between Abbey Wood and Gravesend would be.

  • Belvedere – 10 tph
  • Erith – 10 tph
  • Slade Green – 10 tph
  • Dartford – 16 tph to London via a variety of routes and 10 tph to the East
  • Stone Crossing – 8 tph
  • Greenhithe for Bluewater – 10 tph
  • Swanscombe – 8 tph
  • Northfleet – 4 tph

In addition, Gravesend would have ten tph to and from London.

Handling these frequencies on a modern double-track railway shouldn’t be a problem.

Will Digital Signalling Be Needed?

Crossrail and Thameslink are both digitally signalled and will use a degree of Automatic Train Control, to handle up to twenty-four tph.

I could see advantages in applying similar systems to the Crossrail extension to Ebbsfleet.

Merging Of Services Between Abbey Wood And Belvedere Stations

Services through both these stations would include.

  • 4 tph – Crossrail between London and Ebbsfleet/Gravesend
  • 2 tph – Thameslink between Luton and Rainham, which don’t stop at Belvedere.
  • 4 tph – Southeastern which are the Dartford Loop service to and from Cannon Street.
  • 2 tph – Southeastern between Charing Cross and Dartford

The current track layout appears to allow Crossrail trains to access the North Kent Line, but Class 345 trains are not fitted with shoes for third-rail elecrification.

This Google Map shows the Western end of Belvedere station.

Note how there appears to be space on either side of the double track, which continues as far as Abbey Wood station.

I suspect that a track layout can be designed between the two stations, so that trains can merge and diverge efficiently between the four tracks at Abbey Wood and the two tracks at Belvedere.

Digital signalling would make it easier.

Station Improvement Between Abbey Wood and Grsvesend Stations

As I indicated earlier, Dartford station would need improvement.

On the other hand Abbey Wood, Greenhithe for Bluewater and Gravesend will need very little modification.

I also suspect, Dartford would not be the only station, that will need improvement.

All stations would be made step-free.

A Loop For Ebbsfleet International Station

I feel that the best way to give access to Ebbsfleet International station would be to create a loop from the North Kent Line and use the current island platform 5 and 6 at the station for Crossrail as well.

The Eastern end of the loop has already been built to a high standard and it would only need a Western connection to be designed and constructed.

I’ll repeat the advantanges of this scheme, I listed earlier.

  • Crossrail would have access to a much-needed Park-and-Ride site.
  • The interchange between Crossrail and Continental services would be a short walk.
  • Probably only minimal improvements would be needed to Ebbsfleet International station.
  • There would be a same-platform interchange between Crossrail and HighSpeed commuter services to St. Pancras.
  • Construction would be more affordable and less disruptive.

Each side of the he island platform 5 and 6 would handle.

  • Two tph – HighSpeed commuter services.
  • Four tph – Crossrail services.

They may even be able to handle more trains in the future.

Will Crossrail’s Class 345 Trains Fleet Need Upgrading?

Crossrail’s Class 345 trains have a 90 mph operating speed, as opposed to the 100 mph operating speed of Thameslink’s Class 700 trains.

Southeastern Class 465 trains are even slower at 75 mph.

If all trains working the North Kent Line were 100 mph trains, it would surely make a robust timetable easier to create and operate.

I would expect that in a few years time, all trains working between London and Kent will be capable of at least 100 mph.

Where Will Gravesend and Ebbsfleet International Services Terminate In The West?

The obvious terminal would surely be Heathrow, as this would give a useful service Heathrow and Continental rail services, without the need to change trains.

Wikipedia is quoting 52 minutes between Heathrow and Abbey Wood on Crossrail and current times give  twenty-three minutes between Abbey Wood and Gravesend stations, with perhaps four minutes less to Ebbsfleet in the future.

So timings could be as follows.

  • Heathrow and Ebbsfleet – 75 minutes
  • Heathrow and Gravesend – 79 minutes

Surely, this will be better than struggling around a crowded M25.

Southeastern HighSpeed Commuter Service Improvements

The Southeastern franchise may change later in the year and speculation has started on what this will mean for services and the trains used.

A Revamped HighSpeed Service

In an article in the July 2017 Edition of Modern Railways, which is entitled Kent On The Cusp Of Change, some well-founded speculation is made about the future of the HighSpeed commuter service.

  • More Class 395 trains or similar need to be procured.
  • A new service between St. Pancras and Hastings is planned.
  • An all-day service between St. Pancras and Maidstone West via Gravesend.
  • An extra two tph between St. Pancras and Ebbsfleet International.
  • A second London terminal may be opened at possibly Waterloo or even Victoria.

Only the Maidstone West service would pass through platforms 5 and 6 at Ebbsfleet International station and would add a third hourly HighSpeed service.

In some ways, it might be better for HighSpeed services to run at four tph between Gravesend and St. Pancras via  Ebbsfleet International and Stratford International, as this would fit much better with a four tph Crossrail service.

Improvements To Stratford International Station

Pedestrian routes between the various services and the Olympic Park at Stratford International station are not good.

  • If HighSpeed services are going to be expanded, then it is only right that Stratford International station is improved, to a good modern connectivity standard.
  • If Stansted Airport and Cambridge services serve Stratford in the future, then there must be an easy pedestrian route between the two services.
  • Connectivity between HighSpeed and Great Eastern Main Line and Crossrail services is particularly poor.
  • The HighSpeed platforms at Stratford International station are bleak and draughty and need improvement.

It’s almost as if, the whole station complex was designed for the Eastfield Shopping Centre.

A Summary Of Services By Station

I will look at the current number of trains at stations between Abbey Wood and Faversham, after adding in two extra HighSpeed sevices.

  • St. Pancras and Maidstone West via Strood.
  • St Pancras and Faversham.

These would give.

  • Belvedere – 10 tph
  • Erith – 10 tph
  • Slade Green – 10 tph
  • Dartford – 16 tph to London via a variety of routes and 10 tph to the East
  • Stone Crossing – 8 tph
  • Greenhithe for Bluewater – 10 tph
  • Swanscombe – 8 tph
  • Northfleet – 4 tph
  • Gravesend – 8 tph to London and 7 tph to the East
  • Higham – 2 tph
  • Strood – 6 tph
  • Rochester – 8 tph
  • Chatham – 8 tph
  • Gillingham – 8 tph
  • Rainham – 8 tph to London and 6 tph to the East
  • Sittingbourne – 6 tph

Thameslink Improvements

My only thought about Thamesink, is that if Crossrail and Southeastern’s HighSpeed services run at a frequency of four tph, through Gravesend, then surely Thameslink should run at the same frequency Between St. Pancras and Rainham.

I say St. Pancras rather than Luton, as it would probably be sensible to send the extra two tph up the East Coast Main Line to either Welwyn Garden City, Peterborough or Cambridge.

A Summary Of Services By Station

I will look at the current number of trains at stations between Abbey Wood and Faversham, after adding in two extra Thameslink sevices.

These would give.

  • Belvedere – 12 tph
  • Erith – 12 tph
  • Slade Green – 12 tph
  • Dartford – 18 tph to London via a variety of routes and 12 tph to the East
  • Stone Crossing – 10 tph
  • Greenhithe for Bluewater – 12 tph
  • Swanscombe – 10 tph
  • Northfleet – 6 tph
  • Gravesend – 10 tph to London and 9 tph to the East
  • Higham – 4 tph
  • Strood – 8 tph
  • Rochester – 10 tph
  • Chatham – 10 tph
  • Gillingham – 10 tph
  • Rainham – 10 tph to London and 6 tph to the East
  • Sittingbourne – 6 tph

When you consider that these frequencies are obtained by trains running at 100 mph on a railway, that was most;ly built in the mid-nineteenth century and electrified with 750 VDC third rail before the Second World War.

Southeastern Improvements

Both Southeastern’s Metro services to and from Dartford and Chatham and their main line services to East Kent will probably be improved under the new franchise holder

  • New or refurbished 100 mph trains will replace the 75 mph Class 465 trains.
  • Dover and Ramsgate will get increased frequencies from Victoria.
  • Metro services to and from Dartford and Chatham will be at least a Turn-Up-And-Go four tph.
  • The enhanced performance of the new trains would enable faster services and more stops to be made without degrading the timetable.

I feel that it would not be impossible to see every station between London Bridge and Rainham having twelve tph.

The Pedestrian Link Between Northfleet And Ebbsfleet International Stations

I am not saying a pedestrian link between Northfleet and Ebbsfleet International station shouldn’t be built, but consider that the loop through Ebbsfleet International station gives two routes between Swancombe and Gravesend.; one via Northfleet and the other via Ebbsfleet International.

A lot depends on how many passengers will actually want to travel between the two stations.

  • Those from the West could change at a station like Dartford or Greenhithe for Bluewater to a train going to their required destination.
  • Those from the East could change at Gravesend to a train going to their required destination.

All changes would be same-platform changes and the best stations could be encouraged by coffee kiosks and comfortable waiting rooms.

For passengers starting from Northfleet the following rules would apply.

  • Passengers going East would take the first train and change if required at Bravesend, Rochester or their preferred station.
  • Passengers going West would take the first train and change if required.
  • Passengers going to Ebbsfleet International would probably catch the first train for a single stop and then cross-over to the other platform for a train to Ebbsfleet International.

If there were upwards of six tph on both routes and step-free access at all stations, these procedures would not be unduly tiresome.

Similar rules would apply for those starting their journeys at Ebbsfleet International.

Note that, as more trains ran on both routes between Swanscombe and Gravesend, the time to get between the two stations would decrease.

If as seems to be planned, a lot of housing is built on the undeveloped land between the two stations, I wouldn’t be surprised to see a progressively-minded developer build a pleasant tree-lined pedestrian and cycling route between the two stations.

This would be mainly to give easy access to the development to the two stations, but it would also link them together.

Conclusion

Everything, I have written in this post is based on sound facts and is possible with today’s technology.

  • 100 mph suburban electric trains have been around for several decades.
  • Digital signalling has been successfully running on Thameslink in the UK and other places in the world for a couple of years.
  • The construction methods to build a loop at Ebbsfleet station are nothing out-of-the-ordinary.

What I have outlined would be much more of a £1.3 billion project than a £3 billion one!

I also believe everything can be achieved without massive disruption or inconvenience to passengers and probably delivered in full by 2025.

It should be noted that North Kent will be reaping the benefit of three major new cross-London high-capacity railways.

  • The Chanel Tunnel Rail Link between Ebbsfleet International and St. Pancras via Stratford International.
  • Crossrail between Abbey Wood and West London via Canary Wharf, the City and West End of London, Paddington and Old Oak Common.
  • Thameslink between Kent and North of London via London Bridge, Blackfriars and St. Pancras.

As cross-London routes continue to develop in future decades, other commuter routes will benefit from similar strategies.

Some Trains Only Have Door Controls On One Side Of The Double Door

On Saturday, I was on a very crowded train and needed to get out.

But I couldn’t as there were so many people in the doorway., that I couldn’t reach the door controls, which were only on one side.

Eventually, someone else pushed the button.

I noticed today, that Class 700 trains only have conmtrols on one side.

These buttons should be on both sides.

A Toilet On A London Underground Train

On my short journey between City Thameslink, and London Bridge stations, I sat next to one of the toilets.

I also made use of the facility.

As there is a lot of pressure to show Thameslink on the Tube Map, will these trains become the only trains on the Underground to have toilets?

As modern controlled emission toilets, don’t throw anything on the tracks, they can be safely used anywhere.

Automatic Door Opening On Thameslink

This morning I used Thameslink between City Thameslink and London Bridge stations.

On the three stations on this short route, the doors opened automatically, without passengers having to push any buttons.

This is normal London Underground practice and will it be used on the tunnel stations on Crossrail.

But it struck me, as I got on the train at City Thameslink station, where there is a large gap for passengers to fall into, that automatic opening may well be safer, as passengers don’t have to lean across.

Integration Of High-Speed And Commuter Services Out Of Kings Cross Station

The East Coast Main Line ECML) has the following services on the Southern section between Kings Cross and Peterborough.

  • Express services capable of at least 125 mph running from LNER , Grand Central, Hull Trains and other Open Access operators.
  • Great Northern services capable of 110 mph running between Kings Cross and Cambridge and Ely.
  • Great Northern services to Peterborough appear to have been discontinued.
  • Thameslink services capable of 100 mph running between Kings Cross and Cambridge and Peterborough.

It would appear that the slower  Great Northern and Thameslink services will get in the way of the faster trains, if they need to use the fast lines.

The Digswell Viaduct

A particular problem will be the double-track section of line through Welwyn North station and over the Digswell Viaduct.

There are two Great Northern and  six Thameslink services in each hour, that are not capable of operating at 125 mph on the double-track section.

Following the logic of Oxford and Bedwyn services out of Paddington, which are now run by 125 mph Class 802 trains, I feel that timetabling would be easier on the ECML, if there were 125 mph trains running Great Northern and Thameslink services to Cambridge, Ely and Peterborough.

I explored 125 mph services to Kings Lynn in Call For ETCS On King’s Lynn Route, after reading about a proposal in Rail Magazine. They certainly look like they’d give advantages.

Some idiot decided that Thameslink services were fine with a 100 mph top speed. They should have been 110 mph or even faster trains, so that they could cross the Digswell Viaduct without slowing high speed services.

Digital Signalling

Digital signalling will be installed on the Southern section of the East Coast Main Line

This could ease the problem of the double-track section, as all trains should eventually be timed more precisely.

More Use Of The Hertford Loop

Perhaps some or all of the six 100 mph Thameslink services, could use an upgraded Hertford Loop Line, which will be fitted with digital signalling.

125 mph Trains

In a last resort, it would surely be more affordable to run 125 mph commuter trains to Cambridge, Ely and Peterborough, than put put two extra tracks on the Digswell Viaduct.
