The Anonymous Widower

Calculating Kinetic And Potential Energies

I used to be able to do this and convert the units, manually and easily, but now I use web calculators.

Kinetic Energy Calculation

I use this kinetic energy calculator from omni.

Suppose you have a nine-car Crossrail Class 345 train.

  • It will weigh 328.40 tonnes, according to my detective work in Weight And Dimensions Of A Class 345 Train.
  • There will be 1,500 passengers at 90 Kg. each or 135 tonnes.
  • So there is a total weight of  463.4 yonnes.
  • The train has a maximum speed of 90 mph.

Put this in the calculator and a full train going at maximum speed has a kinetic energy of 104.184 kWh.

The lithium-ion battery in a typical hybrid bus, like a New Routemaster has a capacity of 75 kWh.

So if a full Class 345 train, were to brake from maximum speed using regenerative braking, the energy generated by the traction motors could be stored in just two bus-sized batteries.

This stored energy can then be used to restart the train or power it iin an emergency.

Out of curiosity, these figures apply to an Inter City 125.

  • Locomotive weight – 2 x 70.25 tonnes
  • Carriage weight – 8 x 34 tonnes.
  • Train weight – 412.5 tonnes
  • Passengers – appromiximately 700 = 63 tonnes
  • Speed – 125 mph

This gives a kinetic energy of 206.22 kWh

And then there’s Eurostar’s original Class 373 trains.

  • Weight- 752 tonnes
  • Speed 300 kph

This gives a kinetic energy of 725 kWh.

If a 75 kWh battery were to be put in each of the twenty cars, this would be more than adequate to handle all the regenerative braking energy for the train.

There would probably be enough stored energy in the batteries for a train to extricate itself from the Channel Tunnel in the case of a complete power failure.

Potential Energy Calculation

I use this potential energy calcultor from omni.

Suppose you have the typical cartoon scene, where a ten tonne weight is dropped on a poor mouse from perhaps five metres.

The energy of the weight is just 0.136 kWh.

I’ve used kWhs for the answers as these are easily visualised. One kWh is the energy used by a one-bar electric fire in an hour.

Weight And Dimensions Of A Class 345 Train

If you look at the Wikipedia entry for a Class 345 train, dimensions and weight are rather sketchy.

  • Train length is given as 205 metres.
  • Train width is given as 2780 milli-metres, with a note saying a citation is needed.
  • Train weight is given as less than 350 tonnes.

These would be for a full nine-car train.

This picture shows the identification plate on the end of an MS1 car in the current seven-car train.

These figures can be read.

  • MS1 car weight is given as 36.47 tonnes
  • MS1 car length is given as 22.50 metres
  • MS1 car with is given as 2.78 metres.
  • MS1 car seats are given as 52
  • Train maximum speed is given as 90 mph
  • Train weight is given as 255.46 tonnes.
  • Train length is given as 159.74 metres.
  • Train width is given as 2.78 metres.
  • Train seats are given as 350.


  1. It’s all clearly there in white-on-black.
  2. The Wikipedia figure for car width is correct.
  3. The Wikipedia figure for maximum speed is correct.
  4. I was also able to read the plate on a PMS car, which gave a weight of 37.12 tonnes.

So can I deduce the figures for a full nine-car train, which have two extra cars.

I did find this snippet on the Internet which gives the formation of the nine-car trains.

When operating as nine-car trains, the Class 345 trains will have two Driving Motor Standard Opens (DMSO), two Pantograph Motor Standard Opens (PMSO), four Motor Standard Opens (MSO) and one Trailer Standard Open (TSO). They will be formed as DMSO+PMSO+MSO+MSO+TSO+MSO+MSO+PMSO+DMSO.

The snippet has a date of August 13th, 2016, so it could be out of date.

But is compares well with the current seven-car trains which appear to have a formation something like.

  • Driver-motor car
  • Pantograph car
  • Motor car
  • Trailer car
  • Motor car
  • Pantograph car
  • Driver-motor car

So to convert from a seven to a nine-car train two motor cars are added.

Nine-Car Train Length

This would appear to be 159.74 + 22.50 +22.50 = 204.74 metres.

That would agree with Wikipedia’s figure of 205 metres.

Nine-Car Train Weight

This would appear to be 255.46 +36.47 + 36.47 = 328.40 tonnes.

That would agree with Wikipedia’s figure of less than 350 tonnes.

Details Of The Driver Motor Car

Once I have these details, I’ll have everything I need.

Underneath A Class 345 Train

I was at Shenfield station on Friday waiting for a train to Rayleigh.

Opposite was a Class 345 train waiting to return to London.

As the lighting was just right, I took a few pictures.

There’s some complicated gear underneath.

January 28, 2018 Posted by | Travel | | Leave a comment

Big On The Inside And The Same Size On The Outside

This morning, I took a ride in one of London Overground’s Class 378 trains to Shoreditch High Street station, so that I could have Leon’s version of a Full English Breakfast and a real mug of tea, in their restaurant in Spitalfields. And all for £5.25!

Afterwards, I walked the short distance to Liverpool Street station and took one of Crossrail’s new Class 345 trains to Stratford station.

As the Class 345 train was more or less empty, I was able to take these pictures of the inside.

Several design features are noticeable.

  • The wide flat floor
  • The walk-through design of the train.
  • The wide aisle in the centre.
  • The seats cantilevered from the side of the train.
  • The heating under the seats.
  • The spacious lobbies.
  • The large windows.
  • The way the body sides bulge outwards to create more width at just below shoulder height.

The design seems to create more room for passengers and because of the wide aisle and large windows, the room might even look more spacious than it actually is.

It is certainly a more pleasing train to ride in, than the Class 378 train, I rode ealier, which is very much one of the better trains from the previous generation.

Later I rode on one of Thameslink’s Class 700 trains.

  • The lobbies are wide.
  • Seats obscure the view, as they are not aligned with the windows.
  • The heating takes up space along the side of the train.

But as the sides of the train don’t seem to be so curved, the aisle between the seats seems to be narrower. A lady wheeling a case between the seats would have hit people, if anybody had been sitting in the seats.

I should ride in a full Aventra in the Peak and see if my everybody appears to have more space. I did later!

On the 19th of December, I rode from Romford to Liverpool Street in an Aventra during the morning Peak.

  • The train was perhaps three-quarters full.
  • For some parts of the journey, all seats were taken, but the standees didn’t seem to have too much trouble standing in the smooth-riding train.
  • Only a few were strap-hanging and several were using the backs of seats for support.

It did seem to be a better experuience than other commuter trains.

Others ideas and consequences have emerged in recent months.

Aventras Have Underfloor Heating

The Greater Anglia Class 720 trains have underfloor heating as I detailed in Aventras Have Underfloor Heating.

Underfloor heating would appear to release space for passengers. Especially when it is coupled with seats cantilevered from the sides of the train.

Aventras Have No Doors Between Cars

Tthis article on Global Rail News, which is entitled First look around Greater Anglia’s Bombardier Aventra mock-up, says this.

There will be no doors separating vehicles.

There is just a wide lobby, where the cars are joined together.

This shows the join in a Class 345 train.

Regularly in busy times on London Overground’s Class 378 trains or London Underground’s S Stock, similar areas are full with people.hanging on to the vertical handles or wheelie cases.

It’s a design that seems to work well and again it makes more space available for passengers.

Aventras Can Have 2+3 Seating

This picture shows the inside of Greater Anglia’s Aventra mockup.

Could the 2+3 seating be wider and more comfortable, as Aventras seem to be wider inside at shoulder height, due to the innovative body design?

Note the power sockets in the front of the seats.

Aventra Car Length And Number of Cars Is Flexible

The first two fleets of Aventras ordered had different length cars and different number of cars.

Orders have now been placed for trains with twenty and twenty-two metre length cars and three, four, five, seven, nine and ten cars.

It also seems that it is very simple to change train length by adding and removing cars as required.

Greater Anglia

Greater Anglia have stated that they are ordering ten-car Aventras with similar train lengths to twelve-car sets of their current rolling stock.

Lengths and passenger capacity are given as follows in Wikipedia.

  • Ten-car Class 720 – 243 metres – 1,145 seats
  • Twelve-car Class 321 – 239.4 metres – 927 seats
  • Twelve-car Class 360 – 244.08 metres – 840 seats

This looks like an over thirty percent increase in seats in a train around the same length, with the following advantages

  • Little if any expensive platform extensions. Especially at Liverpool Street station.
  • Trains will fit existing depots and sidings.
  • Nearly all trains will be fixed formations.

The only disadvantage is that Greater Anglia won’t be providing any First Class seats. Judging by the lack of complaints, few seem to be bothered.

But being less complicated, it would probably be a more affordable train to run and maintain.

In this Greater Anglia example, another factor helps.

The Aventra will only have two cabs, whereas three Class 321 or Class 360 trains will have six.So the length released by four cabs is available for passengers.


It would appear that the c2c order, where ten-car Aventras replace twelve-car Electrostars, is another application of the same philosophy, that was used by Greater Anglia.

This is an extract from c2c’s Press Release.

The Aventra is one of the fastest-selling trains in the UK rail industry, and these new trains will be manufactured at Bombardier’s factory in Derby. Each new train, which will operate in a fixed set of 10-carriages, will include over 900 seats, plus air-conditioning, wifi, plug sockets and three toilets onboard. Each new carriage is larger and contains more seats than on c2c’s current trains, so each 10-carriage new train provides capacity for 15% more passengers onboard compared to a current 12-carriage c2c train.

So three x four-car trains working as a twelve-car train are replaced by one ten-car train, just as with Greater Anglia. Note the claimed fifteen percent capacity increase!

West Midlands Trains

West Midlands Trains have ordered three sets of Aventras.

  1. 16 x five-car 110 mph trains for long-distance services.
  2. 29 x five-car 110 mph trains for electrified suburban services.
  3. 36 x three car 90 mph trains for Redditch to Lichfield Trent Valley.


  • Fleet 1 will probably be used to augment the Class 350 trains in pairs on long distance services.
  • Could these work in pairs that split and join en route to save paths into Euston?
  • Fleet 3 will be direct replacements for the Class 323 trains and will probably work in pairs.
  • Would a five-car train have a similar capacity to two three-car trains working as a pair?
  • Would some of the five-car trains in Fleet 2 be fitted with diesel powere-packs or batteries, so they could run services on lines without electrification?

West Midlands Trains must have a plan, or there will be a large number of trains sitting in sidings.


It looks to me like Bombardier have designed a train, where more passengers can be accommodated, without sacrificing passenger comfort.

How Much Energy Does A Crossrail Class 345 Train Use?

I will start with the Crossrail Rolling Stock Technical Fact Sheet, which dates from 2012.

The Class 345 trains were built to this specification.

This is said about the power required.

Energy efficiency of 24 KWh per train kilometre (equivalent of 55g CO2 per passenger kilometre)

So what does this mean now that trains are running and trains will have been designed and probably accepted to this specification.

Assuming, that trains will be nine-car when completed, 24 KWh per train per kiometre translates into 2.67 KWh per car per kiometre or 3.29 KWh per car per mile.

Ian Walmsley’s Train Energy Usage Figure

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.

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

My calculated value is in line with this figure, as the Uckfield Branch is not that different to some of the Crossrail branches.

What Is The Kinetic Energy Of A Crossrail Train?

I ask this question to show the energy values involved.

If I take a nine-car Class 345 train, this has a mass of less than 350 tonnes and a maximum speed of 145 kph.

1500 passengers at 80 kg each works out at another 120 tonnes.

So for this crude estimate I’ll use 450 tonnes for the mass of a loaded train.

This gives the train an energy of 365 megajoules or 101 KWh.

This amount of energy is only a couple of KWh larger than the largest battery size of a Tessla Model S car.

It leads to the conclusion, that batteries could be large enough to store the regenerative energy generated by the train, when it stops.

How Far Could A Crossrail Train Run On Batteries?

If the batteries were sized for the regenerative braking, then a battery of 100 KWh would probably be sufficient in most circumstances.

Using Crossrail’s figure of 24 KWh per train per kiometres, gives a convenient range of four kiometres, which is probably in excess of the largest distance between stations.

But Crossrail trains are effectively two half-trains with two pantographs.

So perhaps they will be fitted with two batteries!

The battery capacity would be arranged to give the desired amount of emergency power.


There’s a lot more to learn about these Crossrail trains.

Will Crossrail Go Up The West Coast Main Line?

This report on the BBC from August 2014, is entitled Crossrail Extension To Hertfordshire Being Considered.

This is the opening paragraph.

Proposals to extend Crossrail to Hertfordshire are being considered by the government, Transport Secretary Patrick McLoughlin has announced.

But then in August 2016, the proposal was cancelled as being poor value for money.

The Wikipedia entry for Crossrail has a section called To the West Coast Main Line, under Extensions.

This is said.

Network Rail’s July 2011 London & South East Route Utilisation Strategy (RUS) recommended diverting West Coast Main Line (WCML) services from stations between London and Milton Keynes Central away from Euston, to Crossrail via Old Oak Common, to free up capacity at Euston for High Speed 2. This would provide a direct service from the WCML to the Shenfield, Canary Wharf and Abbey Wood, release London Underground capacity at Euston, make better use of Crossrail’s capacity west of Paddington, and improve access to Heathrow Airport from the north. Under this scheme, all Crossrail trains would continue west of Paddington, instead of some of them terminating there. They would serve Heathrow Airport (10 tph), stations to Maidenhead and Reading (6 tph), and stations to Milton Keynes Central (8 tph)

That sounds all very sensible. So why was the scheme cancelled?

I will look at various factors to see if I can get an idea!

Current Local Services To Milton Keynes

London Midland currently runs five trains per hour (tph) between Euston and Milton Keynes Central stations using Class 350 trains capable of 110 mph.

The new operator; West Midlands Trains will replace these trains with 110 mph Aventras.

Note that both these trains have to be capable of running at 110 mph, as this is necessary for efficient operation of the West Coast Main Line.

Crossrail Local Services To Milton Keynes

Crossrail’s Class 345 trains are only capable of 90 mph running, but then again, West Midlans Trains will have Aventras capable of 110 mph.

So for a start, the current Crossrail trains would be unable to work services to Milton Keynes in an efficient manner.

I would estimate around twenty trains  would have to be updated for 110 mph running to provide eight tph.

An Upgrade Of Milton Keynes Central Station

With a fast eight tph running to and from Central London, the nature of the train services at Milton Keynes would change dramatically.

How many of Virgin’s passengers to and from the North would prefer to change to a local train at Milton Keynes, rather than lug heavy baggage on the Underground?

HS2 would have an unexpected competitor.

ERTMS On The West Coast Main Line

Would ERTMS need to be installed on the West Coast Main Line to accommodate al these trains?

This will probably happen soon anyway, but Crossrail to Milton Keynes could bring it forward.

Connecting Crossrail To The West Coast Main Line

Look at this map from, which shows the lines in the Old Oak Common area.


  • The West Coast Main Line is the multi-track railway towards the top of the map.
  • The Great Western Main Line is the multi-track railway towards the bottom of the map.
  • The Slow Lines on both main lines are on the Northern side of the tracks.
  • The Old Oak Common station will be on the Great Western Main Line, just to the West of the North Pole Depot.

This all means that a flyover or a tunnel must be built to connect the two pairs of Slow Lines. It’s not simple!

This Google Map of the area illustrates the problem.


  • The Great Western Main Line going across the bottom of the map.
  • The North Pole Depot alongside the Great Western Main Line.
  • The Dudding Hill Line and the West London Line at the Western side of the map.
  • Crossrail’s newly-built depot is the large grey rectangular building.
  • There’s also some housing to the North-West of Crossrail’s Depot

I doubt that a flyover could pass over all that.

But a tunnel starting at the surely soon-to-be-redundant Heathrow Express Depot , that turned North-West would be a possibility.

A tunnel could emerge to the North-West of Harlesden station.

This Google Map shows that area.


  • The silver building in the top-left corner is the Princess Royal Distribution Centre.
  • The West Coast Main Line runs diagonally across the map.
  • The Dudding Hill Line runs up the Eastern side of the map.

I suspect that space for a tunnel portal can be found.

  • Twin tunnels would probably be bored.
  • I estimate that they, would need to be just over two kilometres long.
  • I suspect too, that they could be build without an additional ventilation shaft in the middle.

Looking at these maps, I’m very much of the opinion, that boring a tunnelled solution, would be possible, but what would be the cost?

The Lee Tunnel in East London is about twice as long and larger in diameter. From the cost of that tunnel, which was opened in 2016, I feel that the two tunnels could be built for just under a billion pounds.

A Tunnel-Free Solution

This Google Map shows Old Oak Common between the Great Western Main Line and the West Coast Main Line.

The Crossrail station would be at the bottom just above the North Pole Depot.

I wonder if a line could go through or behind the Heathrow Express site and then follow the North London Line behind the Crossrail Depot to Willesden High Level Junction.

This Google Map shows Willesden High Level Junction and the tracks of the London Overground as they pass over the West Coast Main Line.

I suspect modern three-dimensional design and structural analysis can create a connecting viaduct.

I doubt the track will be much more than a kilometre long and I suspect with the right signallinmg and a degree of Sutomatic Train Control, eight tph each way could be handled on a single track.


It looks like updating the Class 345 trains, ERTMS and building a tunnel under Old Oak Common could be a sizeable bill.

Have cost estimates been such, that the project was not deemed to be value for money?

Transport for London Warns Crossrail 2 Could Be Delayed By Decade

The title of this post is the same as that of an article in the Financial Times.

It’s all about funding and probably the Government not wanting to finance all of the large rail projects.

  • HS2
  • Crossrail 2
  • Northern Powerhouse Rail
  • East West Rail

HS2 is funded and underway and the last two projects are being sorted, but the cost of Crossrail 2 is too much to digest.

I have believed for some time, that Crossrail 2 is a number of separate projects.

  • Increasing capacity on the Waterloo suburban lines
  • Increasing capacity on the Lea Valley Lines
  • Creation of the mega-station at Euston-St. Pancras
  • New trains
  • The high capacity central tunnel

I will now look at each in detail.

Increasing Capacity On The Waterloo Suburban Lines

In An Analysis Of Waterloo Suburban Services Proposed To Move To Crossrail 2, I showed that it would be possible to run a service with Crossrail 2’s characteristics terminating in Waterloo.

I said the following were needed.

  • More platform capacity in Waterloo.
  • Modern high-performance 100 mph trains like Class 707 trains or Aventras.
  • Some improvements to track and signals between Waterloo and Wimbledon stations.
  • Wimbledon station would only need minor modifications.
  • A measure of ATO between Waterloo and Wimbledon stations.

Much of the infrastructure works have been completed as I reported in It’s All Over Now, Waterloo!.

All it needs is Bombardier to build the new Class 701 trains for South Western Railway.

Increasing Capacity On The Lea Valley Lines

In Could A Lea Valley Metro Be Created?, I looked at the possibility of creating a Lea Valley Metro with the following characteristics.

  • Four-tracks between Tottenham Hale and Broxbourne stations.
  • Step-free stations.
  • Termination in the unused loop at Stratford.
  • 10-15 trains per hour.
  • Links to Crossrail, the Underground and Southeastern Highspeed services at Stratford.

I came to the conclusion it was very much possible.

Creation Of The Mega-Station At Euston-St. Pancras

In Should A Mega-Station Be Created At Kings Cross-St. Pancras-Euston?, I looked at this mega station project for Crossrail 2.

I came to these conclusions.

  • If Crossrail 2 is built, there will obviously be a mega station at Euston St. Pancras.
  • But I believe that all the other improvements that will happen before HS2 opens may well be enough to cope with the extra capacity needed.
  • Obviously though, any improvements must not compromise the building of Crossrail’s mega-station.

In Should A Mega-Station Be Created At Kings Cross-St. Pancras-Euston?, I proposed a four-level mega-station.

  • Surface level – National Rail and HS2
  • Sub-surface level – Circle, Hammersmith and City and Metropolitan Lines
  • Deep level – Northern, Piccadilly and Victoria Lines.
  • Very deep level – Crossrail 2

Lines would be connected by escalators, travelators and lifts going all over the place.

It would not be that different to the double-ended Crossrail station at Moorgate-Liverpool Street station, which I described in London’s First Underground Roller Coaster, except that it connects three stations instead of two.

This would enable Crossrail 2 to be bored through at a deeper level after Euston station had been rebuilt for HS2.

In terms of Crossrail 2, the creation of the mega station at Euston St. Pancras could be the last project to be completed.

New Trains

This should be the easy bit, as surely using the same Class 345 trains on Crossrail and Crossrail 2, would be an objective, if it were possible.

The High Capacity Central Tunnel

I’ve never built a tunnel, although my software; Artemis helped to build the Channel Tunnel, but I would suspect that building the central tunnel for Crossrail 2 will be easier than building that for Crossrail.

So many things like riding a bike or sex are a lot easier the second time.

There must be so many lessons from Crossrail that can be applied to Crossrail 2.

If all of the central stations on the tunnel, from Dalston to Wimbledon, where there is interchange with Crossrail 2 can be made tunnel-ready, then I don’t see why boring the central tunnel can’t be one of the last jobs to be started.

The tunnel boring machines would then just pass through the stations to link them all together.

It’s probably not as simple as that, but it is going to be a lot easier job than Crossrail.

The Importance Of The Victoria Line

I’ve never seen this said before, but one of the keys to building Crossrail 2 is the Victoria Line or Dear Old Vicky.

I believe the Victoria Line should be updated as follows to be as near the standard of Crossrail as possible, by using the existing trains, track and signalling  and by updating the stations.

  • Addition of the missing escalators and other features left out to save money in the 1960s..
  • Full step-free access at all stations.
  • Addition of new  entrances at Oxford Circus, Highbury and Islington and Walthamstow Central.
  • Better interchange with the Overground at Blackhorse Road and Walthamstow Central.
  • Better interchange with National Rail at Brixton, Vauxhall, Finsbury Park, Seven Sisters and Tottengham Hale.
  • Forty tph between Brixton and Walthamstow Central.

Forty tph may need a reversing loop at Brixton and an extra one-platform station at Herne Hill.

I believe that an update of this type and scale could be applied to the Victoria Line without causing too much grief for passengers. The work on the stations is necessary to cope with the current and increased passenger numbers and could be carried out in much the same way as the upgrade at Victoria station has been done in the last few years.

The Victoria Line would then offer a high capacity link between Tottenham Hale and Vauxhall prior to the building of Crossrail 2’s central tunnel.

Passengers from say Broxbourne to Hampton Court would take the following route.

  • Lea Valley Line from Broxbourne to Tottenham Hale – (10 tph)
  • Victoria Line from Tottenham Hale to Vauxhall – (>30 tph)
  • South Western Railway from Vauxhall to Hampton Court – (4 tph)

Two changes (both hopefully step-free) would be needed, but with improvement to the National Rail routes at both ends, it would be faster than now.

The Importance Of The Bakerloo Line

Ask TfL’s Journey Planner, which is the quickest way from Tottenham Hale to Waterloo and it gives the following route.

  • Victoria Line from Tottenham Hale to Oxford Circus
  • Bakerloo Line from Oxford Circus to Waterloo

There is a simple cross-platform interchange at Oxford Circus, with the two legs taking 16 and 8 minutes respectively.

Currently, the Bakerloo Line has a frequency of twenty-two tph and plans have been mooted, that will see this going to twenty-seven tph by 2033.

It looks like when combining an updated Victoria Line with the current Bakerloo Line, you get a excellent connection that can stand-in for the Crossrail 2 central tunnel between Tottenham Hale and Waterloo.

But the Bakerloo Line might be extended to Lewisham, so will this extension make the combined Victoria/Bakerloo route more important.

The extended Bakerloo Line is not planned to have a connection with Crossrail 2, so using the Victoria Line across Central London will probably be the fastest way from say Lewisham to Enfield Lock.

It looks to me, that the cross-platform interchange at Oxford Circus between the Bakerloo and Victoria Lines is more important than anybody thinks and will continue to be so.

The Splitting Of The Northern Line

TfL would like to split the Northern Line into two branches, but this can’t be done until Camden Town station is rebuilt around 2024.

The only effect this split will have on Crossrail 2, is it will give extra routes to Euston station, which may probably make it less important that Crossrail 2 is completed before HS2.

A Possible Timetable

This is very much speculation on my part.

  • 2020 – Improved Overground services to Cheshunt, Chingford and Enfield Town using new Class 710 trains.
  • 2021 – Increased Greater Anglia services on the Lea Valley Lines using new Class 720 trains.
  • 2021 – Waterloo suburban branches running at four tph using new Class 701 trains.
  • 2024 – Extended Camden Town station opens.
  • 2024 – Splitting of the Northern Line
  • 2024 – More capacity on the Victoria Line
  • 2025  – Increased services on the Lea Valley Line after four-tracking.
  • 2025 – Upgraded Euston station opens with better connection to the Underground.
  • 2026 – Old Oak Common statio opens
  • 2026 – HS2 opens to Birmingham

The Crossrail 2 central tunnel could be built, when traffic levels are predicted to be too much for the Victoria Line.


This analysis says to me that Crossrail 2 could be planned as a series of much smaller projects, that would give passengers benefits from the early-2020s and also ease the funding problems for the line.

But the analysis also says that if the central tunnel is not built before the 2040s, then the Victoria Line must be upgraded to create a high capacity link between Tottenham Hale and Vauxhall or Waterloo using the Bakerloo Line.

Details In A Class 345 Train Interior

These pictures were taken of internal details of a Class 345 train.

Various thoughts.

Cantilevered Seats

The bays of four-seats are cantilevered to the sides of the train, which means the space underneath the seat is available for luggage and well-behaved dogs.


It would appear that the heating is under the Metro-style seating.

As I said in Aventras Have Under Floor Heating, it would appear that the Greater Anglia Aventras do have under-floor heating, so perhaps this is a customer-chosen option, more suited to longer-distance routes.

The Lobbies

East car in the Class 345 train, has three sets of doors and lobbies.

Note how each lobby has a central handrail and two vertical handrails in each corner. One of these is just behind the door and you can grab it from outside.

Metro-Style Seating

I have not travelled in the Peak, so I don’t know how the seats perform with a full load, but this type of seating works well in the Overground’s Class 378 trains.

Note how the Class 378 seats have wider armrests and are not so open underneath. That vertical handrail in front of the seats can get in the way too!

The Class 378 trains were introduced in 2009, so the differences are probably down to eight years of design and advanced manufacturing.


The armrests have received praise in some reports and they appear to work.

Note how in the metro-style seating the armrests have two levels.


As the first Aventra to enter service, it is a very good effort.

Certainly finding criticism of these interiors is difficult.

If you’re in London and want to go to the Olympic Park or the Eastfield Shopping Centre at Stratford, why not forsake the Jubilee and Central Lines of the Underground and take one of these new trains from Liverpool Street.

There are four trains in service at the present time, but by the end of the year, there will be eleven, so there is an improving chance you’ll get a ride in the best commuter train, in which I’ve ever ridden.

Could Thameslink Connect To Heathrow?

This may seem an outrageous idea.

But I think it could be possible.

Can Class 345 Trains And Class 700 Trains Use The Same Tracks And Platforms?

Crossrail may use Class 345 trains and Thameslink may use Class 700 trains, but can the two trains use the same tracks and platforms?

Recently, Cambridge North station has opened and it will certainly be compatible with Class 700 trains and Greater Anglia’s Class 720 trains, which are closely related to the Crossrail trains.

Heathrow’s platforms do not have platform-edge doors.

Both trains are designed to work at high frequencies using ERTMS.

So I think the answer to my question is a solid yes!

How Would Thameslink Trains Get To Heathrow?

The original plan for Heathrow Express envisaged using both Paddington and St. Pancras as terminals in Central London.

It would have used the Dudding Hill Line as a connection between the Great Western Main Line and the Midland Main Line.

This Google Map shows the tracks to the East of Acton Main Line station.


  • The four tracks of the Great Western Main Line run through Acton Main Line station.
  • The most Southerly pair of tracks are the fast lines, whilst the next pair are the slow lines as used by Crossrail.
  • The tracks shown in orange are the North London Line.
  • The two extra lines to the North of Acton Main Line station are the Goods Lines, connect at Acton Wells Junction to the North London Line, so freight trains can go across London between the Great Western Main Line and Stratford.

After crossing over the Central Line, the route splits with the North London Line going East to Stratford and the Dudding Hill Line going North through Acton Canal Wharf Junction.

To get to and from Heathrow, the services would take the same route as Crossrail to the West of Acton Main Line station.

The services would use the existing Cricklewood Curve Junction to connect with the Thameslink route to the North of Cricklewood station.

What New Infrastructure Would Be Required?

The infrastructure needed would not be of the sort of scale needed for Crossrail or Thameslink.

  • The Dudding Hill Line is would need to be electrified.
  • The Dudding Hill Line is double-track throughout.
  • The 30 mph speed limit of the Dudding Hill Line would need to be increased.
  • Would Harlesden and Dudding Hill stations be reopened or other new ones built?
  • The stations at Heathrow could probably handle Class 700 trains without too much difficulty.
  • There might be a need for a flyover to sort out the tangle of lines between Cricklewood and St. Pancras.

But nothing is too complicated or difficult.

What Frequency Of Thameslink Trains Would Serve Heathrow?

Currently, the following services are provided

  • Heathrow Express has four tph to Terminal 5 via Heathrow Central
  • There is a shuttle between Heathrow Central and Terminal 4, run by Heathrow Express.
  • Heathrow Connect run two tph to Heathrow Central.

When Crossrail opens in December 2019, the service to Heathrow will be four trains per hour (tph) to Terminal 5 and two tph to Terminal 4.

Crossrail will also provide the shuttle between Heathrow Central and Terminal 4.

It is certainly not a system designed by any individual or committee with any sense of good design.

At least, both Terminal 4 and Terminal 5 stations have two terminal platforms, so the two stations should each be able to handle up to eight tph.

If they did this would mean up to sixteen tph on the Heathrow spur, which would be well within the capability of the route and trains running using ERTMS, which will handle up to 24 tph on both Crossrail and Thameslink in the few years.

Under current plans, it appears that when Crossrail opens, the stations will get the following services.

  • Heathrow Central – 10 tph
  • Heathrow Terminal 4 – 2 tph plus shuttles
  • Heathrow Terminal 5 – 8 tph

I’m assuming that Heathrow Connect will quietly fade away.

With a bit of reorganisation of the services, it should be possible to squeeze another six tph into the airport, without building any new terminal platforms.

So I feel that say four tph Thameslink trains to Heathrow would be possible.

Could Crossrail Handle The Extra Trains?

The Thameslink trains would have to run on the Crossrail tracks between Acton Main Line station and Heathrow Airport Junction.

Currently Crossrail are proposing running 12 tph on this section, so as ERTMS can handle double this, I suspect there shouldn’t be too much of a problem.

Could Thameslink Handle The Extra Trains?

This article on Rail Engineer, which is entitled Thameslink Signalling Update, says this about possible Thameslink frequencies.

To meet the specification of 24 tph through the Thameslink core section, it is necessary to deploy Automatic Train Operation (ATO). This will provide a peak theoretical capacity of 30 tph, thereby creating a reliable 24 tph service with acceptable recovery margins.

So an extra six tph could be possible.

Would A Service Between Heathrow and Gatwick Airports Be Possible?

In my view it would be the logical service.

It would certainly be possible!

And it could also be a journey without any change of train!

Would There Be Any Other Useful Connections?

These are a few thoughts and ideas.

Same Platform Interchanges

Cross-city lines like Crossrail, Merseyrail’s Northern Line and Thameslink, have the advantage, that if you are going in the right direction, but are on a train to the wrong destination, you can just get off the train and wait for the correct train.

So if you leave Heathrow on a Gatwick train and you need to go to Maidstone East, you would get off at any of the stations in the central core and wait until the next Maidstone East train arrives.

Everybody will have their own favourite interchanges. Mine would probably be Blackfriars station, as it is above the Thames, has lots of seats and there is a large coffee shop on both platforms.

The ability to do this will mean that all stations South of West Hampstead  Thameslink station will have a very easy link to and from Heathrow.

Reversing Stations

Crossrail has several stations where you can reverse your direction of travel by just walking across the platform. Whitechapel station will allow passengers to go between Abbey Wood and Shenfield stations without going up or down any steps or escalators.

Thameslink only has one reversing station at London Bridge station, although St. Pancras Thamslink has escalators and lifts to allow passengers to change direction in a short time.

West Hampstead Interchange

If plans for a West Hampstead Interchange materialise, this will link the following lines.

  • Chiltern Railways
  • Jubilee Line
  • Metropolitan Line
  • Midland Main L:ine
  • North London Line


  1. This could be a very good interchange to be connected to Heathrow.
  2. West Hampstead Interchange would be a good alternative until Old Oak Common station is built.
  3. Passengers going between Heathrow and stations on the Midland Main Line to the North could change here.

Those like me living along the North London Line would find it a convenient way to get to and from Heathrow.

Kings Cross And St. Pancras Stations

The massive complex at Kings Cross and St. Pancras stations currently links the following lines.

  • Eurostar
  • Midland Main Line
  • East Coast Main Line
  • Southeastern Highspeed services
  • Circle Line
  • Hammersmith and City Line
  • Metropolitan Line
  • Northern Line
  • Piccadilly Line
  • Victoria Line

But the only way to get directly to Heathrow is a nearly hour long journey on the Piccadilly Line. Thameslink could be just over half that time, in a less cramped train.

Blackfriars Station

I use Blackfriars station a lot, as it is my the Tate Modern.

But others will use it as a same platform interchage for reasons I outlined erlier.

London Bridge Station

London Bridge station is another important interchange, with links to the following lines.

  • Southeastern services to Kent
  • Southern services to Surrey and Sussex.
  • Jubilee Line
  • Northern Line


  • This new station is well-equipped and interchange is totally step-free.
  • It is also a short walk to the city across London Bridge.
  • This station will be a very good same platform interchange.
  • The station allows passengers to reverse direction by just walking across the platform.

As with West Hampstead, this could be a very good interchange to be connected to Heathrow.

East Croydon, Orpington and Wimbledon Stations

East Croydon, Orpington and Wimbledon stations, which are important local hubs, would all be well-connected to Heathrow.

Collateral Benefits

Crossrail 2

Crossrail 2 is planning to have a Euston St. Pancras station, which is described like this in Wikipedia.

It would be a “mega station” serving the existing Euston, King’s Cross and St. Pancras main line stations. If funded and completed, it will be one of two such stations on the Crossrail 2 route (the other being Dalston).

If this station is designed properly, I am sure it will have the following.

  • A step-free and convenient link to both Thameslink and Eurostar.
  • Some form of high-capacity hi-tech people-mover, stretching under Euston Road, linking Kings Cross, St. Pancras and Euston stations.

I believe a station design is possible that makes the connection between HS1 and HS2 a no-hassle transfer for all passengers in less than ten minutes.

The people-mover should be in place when HS2 opens in December 2026, so that a credible HS1 to HS2 link opens at the same time.

Gatwick, Heathrow, HS1 And HS2 Will Be On One Rail Line

This could be of tremendous benefit to Londoners, travellers, tourists, rail companies and airlines, but Heathrow might not like it, as it could undermine their dominant position.

If Crossrail 2 opens around 2030, this will bring Stansted into the hub.

The Most Important Railway Station In The World

Eventually, Euston St. Pancras station will become the busiest and most important railway station in the world.

How Will Terminal Development At Heathrow Affect Crossrail And Thameslink?

Heathrow are disclosing a master-plan, for rebuilding a lot of the airport to make it more efficient and up with the best.

  • There will be two main terminals; Heathrow West and Heathrow East with satellites in between handling the actual planes.
  • These two terminals and the satellites will be between the two existing runways, with a passenger and baggage transport system beneath.
  • Terminal Five will become Heathrow West.
  • An extended Terminal Two will become Heathrow East.
  • Crossrail, Heathrow Express and the Underground will serve both main terminals.

I believe that this rebuilding could start in the next few years.

Heathrow will make sure they future-proof rail access, so we could see.

  • More terminal platforms at both Heathrow East and Heathrow West
  • Through platforms at Heathrow West to allow trains to go West from both terminals.
  • Freight shuttles bringing in provisions for the airport, the airlines and the aircraft.

This will allow Crossrail, Thameslink, Heathrow Express and other operators to have as many services as is thought necessary.

The biggest constraint will be the capacity of the Great Western Railway and the two tracks used by Crossrail.

Will Other Operastors Be Allowed Use Heathrow?

This probably depends more on politics than anything else, but technically these facts apply.

Bombardier Aventras

Bombardier have hinted that the design of an Aventra can provide commuter trains like Crossrail’s Class 345 trains and 125 mph expresses.

So it would be likely that a 125 mph Aventra of appropriate length would be able to serve Heathrow, if that were thought necessary!

All Trains Would Be Electric

I suspect that regulations would mean all trains would be electric, as you don’t want diesel or hydrogen fuels in the tunnels under Heathrow.


I also suspect that all trains using the eathrow stations would need to be equipped with ERTMS.

Possible Routes

Who knows what routes will become possible, but as the list of trains grows that are acceptable to Heathrow, various possibilities will arise.

  • Great Western Railway to Bristol
  • Great Western Railway to Cardiff
  • London Overground to Clapham Junction station
  • London Overground to Stratford
  • South Western Railway to Southampton
  • East Midlands Trains to Bedford/Kettering/Corby
  • West Midlands Trains to Watford/Milton Keynes/Birmingham

After Heathrow terminals are updated to East and West, there would be scope for cross country routes going vaguely South-West to North-East calling at both terminals in Heathrow.


Will Thameslink And Crossrail Strangle Heathrow Express?

I wonder if a ink to Thameslink will be more valuable to Heathrow, than Heathrow Express.

  • Abandoning Heathrow Express would release valuable platform space at Heathrow and Paddington.
  • Crossrail and Thameslink together would have connections all over London, rather than just Paddington.
  • Crossrail to and from Paddington would only take about five or six minutes longer.
  • Heathrow Express will have to update their trains with ERTMS and to compete with Crossrail.
  • Heathrow Express usually means a taxi to your hotel to and from Paddington.
  • Crossrail will connect the West End, The City and Canary Wharf to Heathrow.

Convenience and cost will eventually strangle Heathrow Express.


The following statements would appear to be true.

  • Class 345 and Class 700 trains can use the same infrastructure.
  • Crossrail and Thameslink both use ERTMS.
  • The stations at Heathrow,the Western section of Crossrail and the Thameslink core have spare capacity.

This means it should be possible to extend Thameslink services to Heathrow with a frequency of at least four tph, using an electrified Dudding Hill Line.

Some new infrastructure would be required, but nothing as comprehensive, as that for Crossrail and Thameslink.

Why Do UK Train Operating Companies Dislike Siemens Trains?

This post was suggested by this article on Global Rail News, which is entitled TransPennine Express Class 397 Fleet Taking Shape.

The following sections describe how the various train companies are replacing their trains built by Siemens.

TransPennine Express

TransPennine Express (TPE) currently have two fleets of Siemens trains; Class 350 and Class 185 trains.

Class 350 trains

TPE currently has a fleet of ten four-car Class 350 trains, which were built by Siemens and are used on electrified services between Manchester Airport and Scotland. They are being replaced by twelve five-car Class 397 trains.

The comparison between the two trains gives clues as to why the fleet is being replaced.

  • The Class 397 trains are 125 mph capable, which means they can mix it with the Virgin’s Class 390 Pendelinos of a similar performance.
  • The Class 350 trains are only capable of 110 mph.
  • The fleet needed to be increased in number to handle services between Liverpool and Scotland.
  • The five-car Class 397 trains fit the capacity needed for the Scottish routes better than the four-car Class 350 trains.
  • The Class 350 trains don’t have wi-fi/4G and power-points to the current standard on some of the latest trains, like the Aventra.

I’ve not ridden in these trains, so I can’t comment on their quality.

I suspect it’s that the Class 397 trains have the 125 mph capability and adding another 110 mph train from Liverpool to Scotland would be too much for the West Coast Main Line to handle.

If you look at the current scheduled times of Virgin and TPE between Wigan North Western and Glasgow and Scotland, you get the following.

  • Virgin – Wigan North Western to Glasgow – 2 hours 31 minutes
  • TPE – Wigan North Western to Glasgow – 2 hours 46 minutes
  • Virgin – Wigan North Western to Edinburgh – 2 hours 39 minutes
  • TPE – Wigan North Western to Edinburgh – 2 hours 53 minutes

So it looks like the new 125 mph trains could save around fifteen minutes on a journey between North West England and Scotland. In addition to the quicker journey time for passengers, it might mean that TPE can use their trains more efficiently.

Nothing has been said, but I suspect that the new Class 397 trains can couple and uncouple automatically, as the Class 395 trains do regularly.

This would allow TPE to run a service like this.

  • Two five-car trains start independently from Liverpool and Manchester Airport.
  • The trains would couple together at Wigan North Western or Preston.
  • They would then run to Carstairs at 125 mph.
  • The trains would then split.
  • One train would go to Glasgow and the other would go to Edinburgh.

The Southbound service would reverse the process.

In the 1960s, I travelled from Glasgow to Manchester on a service like this. T remember, that I was very late into Manchester, as we were delayed at Carstairs by the late arrival of the train from Edinburgh.

It looks to me, that TPE have decided to replace their Class 350 trains, with a faster and more flexible fleet, that can be run according to passenger demand.

Class 185 Trains

TPE also have a fleet of fifty-one three-car Class 185 trains, that were built by Siemens in 2005-2006.

These trains were in some ways very badly-specified for the route and have some deficiencies.

  • There are not enough of them and they suffer badly from overcrowding.
  • They are 100 mph trains, which means they are inadequate on the West Coast and East Coast Main Lines.
  • They lack wi-fi and power sockets.
  • They are diesel trains, that sometimes work on electrified lines, like Liverpool to Manchester and Leeds to Newxastle.

It is no surprise that TPE have decided to replace twenty-two of the Class 185 trains with Class 68 locomotive-hauled Mark 5 coaches and Class 802 trains.

  • This gives a twenty-seven percent increase in the number of carriages.
  • The Class 802 trains are 125 mph capable, so will be very handy for Liverpool to Newcastle and in a few years time to Edinburgh.
  • The coaches are also built to be capable of 125 mph, but they would need faster locomotives to run at that speed.
  • The new fleet will have the wi-fi and power sockets that passengers require.

This new fleet will certainly be better suited to TPE’s needs.

Greater Anglia

Greater Anglia are replacing all their trains, including their fleet of twenty-one four-car Class 360 trains, that were built by Siemens in 2002-2003.

However, in the August 30th Edition of Rail Magazine, there is an article entitled Trio Of Class 360 Desiros Reach Norwich For GA Timing Test.

It appears that, as the fastest trains in Greater Anglia’s fleet, they are being tested in case the new Class 745 trains are not ready before January 1st, 2020, when the Mark 3 coaches have to be retired.

South Western Railway

South Western Railway have a mixed fleet, which includes a lot of trains built by Siemens.

Class 707 Trains

South Western Railway (SWR) are still taking deliveries from Siemens of a fleet of thirty five-car Class 707 trains, that they inherited from South West Trains.

However, they have decided to replace the trains and their Class 455 trains with new Aventras.

I think that the main reason for having a fleet of 100 mph suburban trains, is that they get lots of advantages when it comes to creating passenger-friendly timetables.


But there are other reasons.

  • SWR have said that all their trains will have toilets. The Class 707 trains don’t.
  • The new fleet contains a lot of ten-car trains, whereas the Class 707 trains are all five cars.
  • If all the trains are identical, this must give advantages with respect to management of trains and staff.

It looks to me, that South West Trains choice of fleet wasn’t in tune with SWR’s philosophy.

The Return Of The Class 442 Trains

Surprisingly, SWR are bringing back thirty-year-old Class 442 trains for the London to Portsmouth routes.

SWR probably need more trains to augment their forty-five Class 444 trains and a hundred plus Class 450 trains, which were all built by Siemens around the turn of the millennium.

Refurbishing the Class 442 trains is probably more affordable than ordering more trains from Siemens.

They can also be fitted with wi-fi, which the Class 444 and Class 450 trains lack.

West Midlands Trains

West Midlands Trains will takeover from London Midland in December 2017.

Currently, London Midland operate seventy-seven four-car Class 350 trains, built by Siemens in 2004-2014.

West Midlands Trains have promised to introduce 225 new carriages on Euston services.

As these trains work on the West Coast Main Line will they be 125 mph units like the Class 397 trains, so they can mix it with the Pendelinos?

Whatever happens, it does seem that the 100-110 mph Class 350 trains without wi-fi, may be living on borrowed time.


Thameslink is now a rail line run exclusively by Class 700 trains, built by Siemens in the last few years.

The trains were ordered without wi-fi and passengers are often critical of the trains.

In my opinion, the trains are inferior to Crossrail’s Class 345 trains, which have both wi-fi and 4G connectivity.


When I travel in a train that Siemens have built for the UK network, I often feel disappointed and think that they could have done better.

Perhaps the exceptions are South Western Railway’s Class 444 and Class 450 trains, but they lack wi-fi. These trains were built some years ago before it had been invented.


The Department for Transport now insists that passengers get free wi-fi and Crossrail is throwing in 4G connectivity as well.

I’m not sure, if there’s a Siemens train in the UK with wi-fi.

But then most trains in Germany have very poor wi-fi in my experience.

Could the design of Siemens trains make fitting of wi-fi and UK-sized power sockets difficult?


Most trains these days are leased on long-term contracts, which includes maintenance. Could this cause problems with updating trains?

With the old BR-era trains, there are several depots and factories where trains can be updated and Bombardier seem to update their old tranis regularly at Derby. So is Siemens unprepared to update its older trains on the UK network?

The Aventras Are Coming

The first Class 345 trains are appearing with a quiet and smooth ride, excellent performance and wi-fi and 4G connectivity.

Siemens will have to raise their game to compete.
