What Will Happen To Great Western Railway’s Class 387 Trains?

I have been looking at the services that Great Western Railway run using Class 387 trains.

Current services run by these trains are.

London Paddington And Didcot Parkway

This service has the following characteristics.

  • The frequency is two trains per hour (tph)
  • Services are run by two trains working as a pair.
  • Intermediate stops are Ealing Broadway, Southall, Hayes and Harlington, West Drayton, Iver, Langley, Slough, Maidenhead, Twyford, Reading, Tilehurst, Pangbourne, Goring and Streatley and Cholsey.
  • Journey time is one hour twenty-three minutes, giving a three hour round trip.

I estimate that twelve trains are needed to run this service.

From the 15th December 2019, this service appears to run to a similar timetable.

London Paddington And Reading

This service has the following characteristics.

  • The frequency is two tph.
  • Services are run by two trains working as a pair.
  • Intermediate stops are Ealing Broadway, Southall, Hayes and Harlington, West Drayton, Slough, Burnham, Maidenhead and Twyford
  • Journey time is fifty-seven minutes, giving a two and a half hour round trip.

I estimate that ten trains are needed to run this service.

From the 15th December 2019, this service will be run by TfL Rail using Class 345 trains.

Reading And Newbury

This service has the following characteristics.

  • The frequency is one tph.
  • Services are run by two trains working as a pair.
  • Intermediate stops are Reading West, Theale, Aldermaston, Midgham, Thatcham and Newbury Racecourse.
  • Journey time is  twenty-nine minutes, giving an hour round trip.

I estimate that two trains are needed to run this service.

From the 15th December 2019, this service appears to run to a similar timetable.

Current Trains Needed

Summarising the trains needed gives the following.

  • London Paddington and Didcot Parkway – twelve trains
  • London Paddington and Reading – ten trains
  • Reading and Newbury – two trains.

This gives a total of twenty-four trains.

Trains Needed After 15th December 2019

Summarising the trains needed gives the following.

  • London Paddington and Didcot Parkway – twelve trains
  • London Paddington and Reading – no trains
  • Reading and Newbury – two trains.

This gives a total of fourteen trains.

Heathrow Express

Heathrow Express will use twelve Class 387 trains in the near future.

Great Western Railway’s Future Need For Class 387 Trains

Summarising the trains needed gives the following.

  • London Paddington and Didcot Parkway – twelve trains
  • Reading and Newbury – two trains.
  • Heathrow Express – twelve trains.

This gives a total of twenty-six trains.

Great Western Railway have a total of forty-five Class 387 trains. Wikipedia is a bit confusing on this point, but I’m fairly certain this is a correct figure.

This means that Great Western Railway have nineteen trains available for expansion of services.

Great Western Railway’s Class 769 Trains

Great Western Railway have also ordered nineteen dual-voltage bi-mode Class 769 trains.

These are for the following routes.

  • Reading – Redhill or Gatwick Airport
  • London Paddington – Reading and Oxford

As the spare number of Class 387 trains is the same as that of the bi-mode trains, was it originally intended, that these routes could be run by the Class 387 trains, after Network Rail had joined the electrification together.

But the extra electrification never happened.

So Great Western Railway ordered the bi-modes trains.

Great Western Railway’s Dilemma

The Class 769 trains appear to be running late, so Great Western Railway are running the Gatwick and Oxford services with diesel multiple units, that they’d like to send to the West Country.

Bombardier appear to have moved on with their battery technology, that was successfully trialled using a similar Class 379 train in 2015. I wrote about the possibility of battery Electrostars on the Uckfield Branch last month in Battery Electrostars And The Uckfield Branch.

I believe that both routes would be within range of a battery-electric Class 387 train.

Reading – Redhill or Gatwick Airport

The various sections of the route are as follows.

Reading and Wokingham – Electrified with 750 VDC third-rail.

Wokingham and Aldershot South Junction – Not electrified – 12 miles

Aldershot South Junction and Shalford Junction – Electrified with 750 VDC third-rail.

Shalford Junction and Reigate – Not electrified – 17 miles

Reigate and Redhill/Gatwick – Electrified with 750 VDC third-rail.

To my mind, this is a classic route for a battery-electric train, as it is mainly electrified and both gaps are less than twenty miles long.

Some or all of the Class 387 trains are dual-voltage.

London Paddington – Reading and Oxford

The distance between Didcot Parkway and Oxford is under twelve miles, so a return trip should be well within range of a battery-electric Class 387 train.

There are also plans at Oxford station to put a new bay platform on the London-bould side of the station. This could be fitted with a charging station to avoid any range anxiety.

A Gatwick And Oxford Service

Could the Oxford and Gatwick services be joined together to make a direct Oxford and Gatwick service via Reading?

  • I estimate that the service would take around two hours.
  • Assuming a fifteen minute turnround at both ends, a round trip would be four and a half hours.

Running a half-hourly service would need just nine trains.

Or eighteen, if they were to run as eight-car trains!

Could this explain the order for nineteen trains, as it’s always a good idea to have a spare?

Conclusion

Great Western Railway can dig themselves elegantly out of a hole of Network Rail’s making by converting the spare Class 387 trains to battery-electric trains.

I’m sure Bombardier have the design available and would be happy to oblige after they have  finished conversion of the Heathrow Express units.

There might also be an argument for fitting all Class 387 trains with batteries.

  • A more unified fleet.
  • Train recovery in the event of electrification failure.
  • Better safety in depots.
  • Direct services between Paddington and Henley and Bourne End.
  • Would it allow Class 387 trains to run between Paddington and Bedwyn?
  • Reduced electricity consumption.

It’ll be a decision for the accountants.

One collateral benefit of a successful conversion program for the Great Western Railway, is that it would enable Great Northern’s twenty-eight trains and c2c’s six trains to be easily converted to battery-electric versions.

  • Great Northern’s coulde be used by sister company; Southern on the Uckfield Branch and the Marshlink Line.
  • c2c trains are soon to be replaced by new trains.

I’m sure that quality four-car battery-electric trains won’t wait long for an operator.

A Stray TransPennine Express Class 802 Train In London

I took these pictures of a TransPennine Express Class 802 train running around London.

In the first three pictures, it was parked in the sidings to the East of Southall station.

The rest were taken at Willesden Junction station.

Looking at Real Time Trains it appeared to be going between the Hitachi depots at North Pole and Doncaster.

Is This The Longest Bus Stop Repair in London’s History?

This picture shows the bus stop outside Dalston Junction station.

I use this bus stop regularly and since about 2012, the top bit above the information has been missing.

But not any more!

Crossrail’s Paddington Service Plans Revealed

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

This is the first paragraph.

Trains from London Paddington Crossrail station to Shenfield will begin six months after trains start serving the low-level station from other destinations.

In Crossrail Ltd Outlines Plan To Complete The Elizabeth Line,, which I wrote in April 2019, I quoted these points from a statement on the Crossrail web site.

  • Crossrail Ltd has identified a six-month delivery window with a midpoint at the end of 2020.
  • Bond Street station will open later.
  • Service will be initially twelve trains per hour (tph) between Paddington and Abbey Wood stations.
  • Services between Paddington and Reading will commence in December 2019 with a frequency of 4 tph in the peak.

None of these promises from six months ago appear to have been changed.

So my comment at the time still stands.

Twelve trains per hour (tph) gives a capacity of 18,000 passengers per hour, which compares with the 36 tph and 31,500 passengers per hour of the Victoria Line.

Practically, this means that a twelve tph Crossrail could be carrying sixty percent of the number of passengers of the Victoria Line. It’s better than a kick in the teeth!

But then Dear Old Vicky is the Platinum Standard with lots of encrusted diamonds!

There is also other information in the Rail Magazine article.

  • Paddington to Shenfield services will start six months after the start of Paddington to Abbey Wood services.
  • Services will initially use the two-platform Crossrail station under Paddington as a terminus.
  • Through services are expected to start a year later.

It looks like Crossraill should be fully open by the May 2022 timetable change.

This map from carto.metro.free.fr shows the layout of the lines at Paddington station.

Note that if you go pass the Crossrail tunnel portal on a train, there are generally several of Crossrail’s Class 345 trains to be seen, lined up in front of Westbourne Park bus garage.

These pictures were taken in July 2019.

A Selection Of Train Noses

I have put together a selection of pictures of train noses.

They are in order of introduction into service.

Class 43 Locomotive

The nose of a Class 43 locomotive was designed by Sir Kenneth Grange.

Various articles on the Internet, say that he thought British Rail’s original design was ugly and that he used the wind tunnel at Imperial College to produce one of the world’s most recognised train noses.

  • He tipped the lab technician a fiver for help in using the tunnel
  • Pilkington came had developed large armoured glass windows, which allowed the locomotives window for two crew.
  • He suggested that British Rail removed the buffers. Did that improve the aerodynamics, with the chisel nose shown in the pictures?

The fiver must be one of the best spent, in the history of train design.

In How Much Power Is Needed To Run A Train At 125 mph?, I did a simple calculation using these assumptions.

  • To cruise at 125 mph needs both engines running flat out producing 3,400 kW.
  • Two locomotives and eight Mark 3 carriages are a ten-car InterCity 125 train.

This means that the train needs 2.83 kWh per vehicle mile.

Class 91 Locomotive

These pictures show the nose of a Class 91 locomotive.

Note, the Class 43 locomotive for comparison and that the Driving Van Trailers have an identical body shell.

It does seem to me, that looking closely at both locomotives and the driving van trailers, that the Class 43s  look to have a smoother and more aerodynamic shape.

Class 800/801/802 Train

These pictures show the nose of a Class 800 train.

In How Much Power Is Needed To Run A Train At 125 mph?, I did a simple calculation to find out the energy consumption of a Class 801 train.

I have found this on this page on the RailUKForums web site.

A 130m Electric IEP Unit on a journey from Kings Cross to Newcastle under the conditions defined in Annex B shall consume no more than 4600kWh.

This is a Class 801 train.

  • It has five cars.
  • Kings Cross to Newcastle is 268.6 miles.
  • Most of this journey will be at 125 mph.
  • The trains have regenerative braking.
  • I don’t know how many stops are included

This gives a usage figure of 3.42 kWh per vehicle mile.

It is a surprising answer, as it could be a higher energy consumption, than that of the InterCity 125.

I should say that I don’t fully trust my calculations, but I’m fairly sure that the energy use of both an Intercity 125 and a Class 801 train are in the region of 3 kWh per vehicle mile.

Class 717 Train

Aerodynamically, the Class 700, 707 and 717 trains have the same front.

But they do seem to be rather upright!

Class 710 Train

This group of pictures show a Class 710 train.

Could these Aventra trains have been designed around improved aerodynamics?

  • They certainly have a more-raked windscreen than the Class 717 train.
  • The cab may be narrower than the major part of the train.
  • The headlights and windscreen seem to be fared into the cab, just as Colin Chapman and other car designers would have done.
  • There seems to be sculpting of the side of the nose, to promote better laminar flow around the cab. Does this cut turbulence and the energy needed to power the train?
  • Bombardier make aircraft and must have some good aerodynamicists and access to wind tunnels big enough for a large scale model of an Aventra cab.

If you get up close to the cab, as I did at Gospel Oak station, it seems to me that Bombardier have taken great care to create a cab, that is a compromise between efficient aerodynamics and good visibility for the driver.

Class 345 Train

These pictures shows the cab of a Class 345 train.

The two Aventras seem to be very similar.

Class 195 And Class 331 Trains

CAF’s Class 195 and Class 331 trains appear to have identical noses.

They seem to be more upright than the Aventras.

Class 755 Train

Class 755 trains are Stadler’s 100 mph bi-mode trains.

It is surprising how they seem to follow similar designs to Bombardier’s Aventras.

  • The recessed windscreen.
  • The large air intake at the front.

I can’t wait to get a picture of a Class 755 train alongside one of Greater Anglia’s new Class 720 trains, which are Aventras.

Travel Industry Confirms Rail ‘Renaissance’ In Europe

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

This is the introductory paragraph.

Assertions that long-distance rail services in Europe are rapidly becoming more popular as passengers eschew flying for environmental reasons were amply confirmed at the Rail Innovation Forum organised by Amadeus at its head office near Nice on October 9-10.

The article also gives these points.

  • Swiss Federal Railways are reporting a 26 % year-on-year increase in passengers for the first quarter of 2019 for night trains.
  • Sweden is reporting a 12 % increase in rail traffic and a 4 % drop in air traffic.
  • Flight bookings across Scandinavia are down by 10 %.
  • German long-distance rail travel is rising.

This all seems good news for carbon emissions.

Rumours Grow Over Future Of HS2

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

This is the first paragraph.

The future of HS2 appears to be increasingly in doubt, as reports suggest that the forthcoming Oakervee Review will axe Phase 2b between the West Midlands and Yorkshire and possibly cancel the project entirely.

The article also says this about the first phase of the project.

Another possibility is that Phase 1 between London and Birmingham could be built more cheaply by lowering the maximum speed from the presently-planned 250km/h. Such a reduction would reduce the new line’s capacity and lengthen journey times but still ease the pressure on the West Coast Main Line, where paths are in short supply.

There are three suggestions in these two paragraphs and before I discuss them, I’ll detail the various phases of the project as they are current proposed.

The Phases Of High Speed Two

High Speed Two will be two phases with the second phase split into two.

  • Phase 1 – London and the West Midlands
  • Phase 2a – West Midlands and Crewe
  • Phase 2b – Crewe and Manchester and West Midlands and Leeds

The plan improves links between London and several major cities in the Midlands and North.

Northern Powerhouse Rail

I am a great believer in holistic design and in the economies of doing several similar projects together or in a well-defined sequence, that delivers benefits in a stream.

For that reason, I believe that the equally-important Northern Powerhouse Rail should be designed in conjunction with High Speed Two, to achieve the following objectives.

  • A better railway, that connects more towns and cities.
  • A phased delivery of benefits.
  • Possible cost savings.

This report on the Transport for the North web site which is entitled At A Glance – Northern Powerhouse Rail, advocates a much better approach.

  • High Speed Two would go from Crewe to Hull via Warrington, Manchester Airport, Manchester Piccadilly, Huddersfield, Bradford and Leeds.
  • Northern Powerhouse Rail would go from Liverpool to Hull via Warrington, Manchester Airport, Manchester Piccadilly, Huddersfield, Bradford and Leeds.
  • There would be a double junction at High Legh between Liverpool and Manchester, that connects the two routes.
  • London and Liverpool services would use the Western end of Northern Powerhouse Rail from High Legh.
  • There would be improvements East of Leeds to connect to Sheffield and the East Coast Main Line.

This map shows the high speed railways between Crewe, Liverpool, Manchester and Warrington.

I discussed, what has been proposed by Transport of the North in Changes Signalled For HS2 Route In North.

Cutting High Speed Two To An Affordable Budget

I’ll take the three suggestions in the Rail News article.

Suggestion One – Cancel The Project

This is actually the second suggestion, but I think the article kills it in the second paragraph, that I quoted, when it says that High Speed Two is needed to ease pressure on the West Coast Main Line.

Cancellation would probably be a vote loser and a big stick with which to beat Boris, if he brought forward any environmental proposals.

I doubt cancellation will happen, unless we get someone like Nigel Farage as Prime Minister.

Suggestion Two – Cancel Phase 2b Between The West Midlands And Yorkshire

This clip of a map from the Transport for the North report shows a schematic of the rail links to the East of Manchester.

Northern Powerhouse Rail would offer a lot of improvements, which are shown in purple.

There are also these projects that will improve trains to and from Yorkshire.

  • Northern Powerhouse Rail between Liverpool and Hull via Manchester Airport, Manchester Piccadilly, Huddersfield, Bradford and Leeds.
  • A possible connection between Northern Powerhouse Rail and High Speed Two at High Legh.
  • Midland Main Line upgrade with 125 mph bi-mode trains between London and Sheffield.
  • 140 mph running on the East Coast Main Line between London and Doncaster and onward to Bradford, Hull, Leeds and York.

I’ll add a few more flesh to the points.

High Speed Two To Hull

If High Speed Two connects to Northern Powerhouse Rail at High Legh it will join everything together.

  • High Speed Two trains would run between London and Hull via Birmingham, Crewe, Manchester Airport, Manchester Piccadilly, Huddersfield, Bradford and Leeds.
  • Very expensive infrastructure would be shared between High Speed Two and Northern Powerhouse Rail.
  • Leeds and Manchester would be just twenty minutes apart, with trains from both lines on the same tracks.
  • Hull station has the space to handle the trains.

Combining the two routes should save billions.

Midland Main Line To Sheffield, Rotherham, Barnsley, Wakefield And Leeds

This is already ptoposed for the Midland Main Line.

  • New stations will be built at Rotherham and Barnsley.
  • Four fast trains per hour between Sheffield and Leeds can be delivered.
  • 125 mph bi-mode trains to Yorkshire via the East Midlands.

But what about the following?

  • Could the Erewash Valley Line be used instead of a new High Speed Two line between the East Midlands and Sheffield?
  • Could the Midland Main Line be electrified and upgraded to 140 mph running like the East Coast Main Line?

Similar connectivity to that of High Speed Two can be created at a lower cost.

Cancellation of the Eastern Leg of Phase 2b would mean there would be no improved link between the West and East Midlands.

Perhaps, the Eastern leg of High Speed Two, would run only to the proposed East Midlands Hub station at Toton.

Increasing Capacity On The East Coast Main Line

In Thoughts On A 140 mph East Coast Main Line Between London And Doncaster, I did a crude calculation to see how many extra trains could be run between London and Doncaster on a digitally signalled 140 mph East Coast Main Line.

This was my conclusion.

If something similar to what I have proposed is possible, it looks like as many as an extra seven tph can be accommodated between Kings Cross and the North.

That is certainly worth having.

Extra trains could be run between Kings Cross and Bradford, Hull, Leeds, Nottingham and Sheffield.

Estimated timings would be eighty minutes to Doncaster and under two hours to Leeds.

Suggestion Three – Reduce Speed In Phase 1

There is always a tendency for project promoters to make sure their project is the biggest and the best.

There will be an optimum speed for a London and Birmingham high speed line, which balances benefits, costs, noise and disturbance. One politician’s optimum will also be very different to another’s.

Such parameters like operating speed and capacity must be chosen with care.

Conclusion

I believe, that we need the capacity of both High Speed Two and Northern Powerhouse Rail  to move passengers and freight.

So we should design them together and with other improvements like the Midland Main Line and the East Coast Main Line.

Thoughts On A 140 mph East Coast Main Line Between London And Doncaster

The East Coast Main Line is being upgraded with digital signalling to allow Azumas and other high speed trains to run at 140 mph for most of the route, starting with the section between London and Doncaster.

There is also a string of projects all along the line to improve operating speed, cut out slow trains and improve junctions and crossings.

Finsbury Park And Stevenage

In The New Fifth Platform At Stevenage Station – 11th October 2019, I talked about the improvements at the Northern end of the Hertford Loop Line, which I believe could allow the fast lines between Stevenage and Finsbury Park stations to be exclusively used by digitally-signalled 140 mph trains.

Currently, these passenger services run between Stevenage and Finsbury Park in a typical hour.

  • LNER – Edinburgh – 2 trains – #
  • LNER – Leeds – 2 trains – #
  • LNER – Newark or York – 1 train – #
  • Great Northern – Cambridge and Ely expresses – 2 trains
  • Thameslink – Cambridge stopping trains – 2 trains.
  • Thameslink – Peterborough and Horsham – 2 trains
  • Thameslink – Cambridge and Brighton – 1 train
  • Hull Trains – 7 trains per day. – #
  • Grand Central – 9 trains per day. – #
  • East Coast Trains – 5 trains per day. – From 2021. – #

The services can be divided into four groups.

140 mph Non-Stop Expresses

Services marked with a hash (#) will probably  be run by versions of Hitachi Class 80x trains or similar, which will be capable of 140 mph running under digital signalling, between Finsbury Park and Stevenage stations.

The twenty-one services run by Hull Trains, Grand Central and East Coast Trains, will probably add up to less than two trains per hour (tph).

This means that there is a need to run seven tph between Finsbury Park and Stevenage.

Kings Cross and Cambridge/Ely Expresses

Currently, these go non-stop between Kings Cross and Cambridge on the fast lines.

Surely, these should be 140 mph-capable trains, so they fit in with all the fast expresses.

After all, Oxford is served by 140 mph-capable trains, so why not Cambridge?

Cambridge Stopping Trains

The half-hourly Cambridge stopping trains have to stop in Welwyn North station,

  • They will have to use the fast lines between Welwyn Garden City and Knebworth stations, as there are only two tracks.
  • Currently, trains are timetabled to take nine minutes to pass through the double-track section.
  • North and South of the double-track section, the services will use the slow lines, as they call at several stations

But these services still leave forty-five minutes in every hour, in which to fit the 140 mph services through the restricting double track section.

These services will be replaced by a two tph Thameslink service between Cambridge and Maidstone East stations.

Thameslink Cross-London Services

The two Thamelink Cross-London services between Peterborough and Horsham and Cambridge and Brighton, go non-stop between Finsbury Park and Stevenage stations.

So could these three services use the Hertford Loop Line?

  • North of Stevenage, they use the slow lines.
  • South of Finsbury Park, they use the slow lines to access the Canal Tunnels for the Thameslink platforms at  St. Pancras.
  • Would calls at perhaps Alexandra Palace, Enfield Chase and Hertford North be worthwhile.

The only disadvantage would be that the route would be a few minutes slower, than using the main line.

Trains Terminating At Kings Cross Station

In each hour, it appears that the following trains will terminate at Kings Cross station.

  • Seven 140 mph expresses, that are going North of Hitchin.
  • Two 140 mph expresses, that are going to Cambridge/Ely.
  • Two stopping services, that are going to Cambridge.

The station has nine platforms in the main station and three in the suburban station at the side.

The Wikipedia entry for Kings Cross station, has a section entitled Future Remodelling, where this is said.

In January 2018, it was announced that half the station would close for 3 months from January to March 2020 for remodelling work to the station and its approach, expected to cost £237 million. This includes rationalisation of the tracks, reopening the third tunnel to the approach of the station and closure of platform 10.

The remodelling must allow an increase in numbers of trains terminating at Kings Cross, especially as the problems in the throat should be sorted.

These points should be noted about the High Speed Two platforms at Euston.

  • There are eleven platforms.
  • They can handle eighteen tph.
  • The trains will be up to four hundred metres long.

Considering that a nine-car Class 801 train is less than 240 metres long, I wouldn’t be surprised to find that Kings Cross can handle eighteen tph.

Does that mean that Kings Cross station can accommodate another seven services?

Would The East Coast Main Line Be Able To Handle Eighteen 140 mph Expresses An Hour?

If Kings Cross station can handle eighteen tph, then the two fast lines of the East Coast Main Line must be able to handle this number of trains.

  • The two fast lines of the East Coast Main Line between London and Doncaster could be considered a smaller and slower version of High Speed Two.
  • High Speed Two has a capacity of eighteen tph.
  • High Speed Two trains are almost twice as fast as those on the East Coast Main Line.
  • Signalling on the East Coast Main Line will have to deal with slower trains, where there are less than four tracks, as over the Digswell viaduct and through Welwyn North station.

This is just the sort of challenge, for which digital signalling has been created.

Spare Capacity South Of Hitchin

Suppose in a couple of years the following has been done.

  • Kings Cross station has been remodelled.
  • The Hertford Loop Line has been updated for more and faster trains.
  • Thameslink services can use the Hertford Loop Line.
  • Thameslink is running the full 24 tph service.
  • The Cambridge stopper has been changed into a Thameslink service between Cambridge and Maidstone East.
  • Cambridge and Brighton has become a two tph service.
  • Kings Cross and Cambridge/Ely expresses are run by 140 mph-capable trains.

This would mean the following frequencies, to the South of Hitchin.

  • Seven tph – 140 mph-capable expresses between Kings Cross and the North, with some stopping at Stevenage.
  • Two tph – 140 mph-capable expresses between Kings Cross and Cambridge/Ely.
  • Two tph – 100 mph Thameslink services between Cambridge and Brighton routed via the Hertford Loop Line.
  • Two tph – 100 mph Thameslink services between Peterborough and Horsham routed via the Hertford Loop Line.
  • Two tph – 100 mph Thameslink services between Cambridge and Maidstone East routed via the East Coast Main Line. The slow line will be used except over the Digswell viaduct and through Welwyn North station.

Note.

  1. There will also be a two tph Thameslink service in the Peak between Welwyn Garden City and Sevenoaks. This can be discounted as it avoids the tricky bits of the East Coast Main Line.
  2. Thameslink services to Cambridge and Peterborough would be routed via the Hertford Loop ine, at a frequency of four tph.
  3. All Thameslink services would be routed via the Canal Tunnels and St. Pancras station.
  4. Kings Cross would only be handling 140 mph-capable trains, at a frequency of nine tph.

If the capacity of the 140 mph fast lines is the same as the similar High Speed Two, then eighteen tph should be possible.

Planned trains could be as follows.

  • Seven tph – 140 mph-capable expresses between Kings Cross and the North, with some stopping at Stevenage.
  • Two tph – 140 mph-capable expresses between Kings Cross and Cambridge/Ely.
  • Two tph – Thameslink service between Cambridge and Maidstone East.

Does that mean another seven tph can be accommodated between Kings Cross and Hitchin?

As only nine tph would be going into Kings Cross, the station should have no difficulty handling that number of trains. It could possibly handle another nine tph.

Spare Capacity North Of Hitchin

At Hitchin, the following services wukk go to and from Cambridge.

  • Two tph – 140 mph-capable expresses between Kings Cross and Cambridge/Ely.
  • Two tph – Thameslink service between Cambridge and Maidstone East.

The other Thameslink services can be ignored, as they use the slow lines between Stevenage and Hitchin and the Hertford Loop Line, so they are out of the way of the 140 mph services.

Does that mean another ten tph can be accommodated between Hitchin and the North?

What Limits The Number Of Extra Trains?

My crude estimation appears to show the following.

  • Kings Cross station may be able to handle another nine tph.
  • Between Kings Cross and Hitchin may be able to handle another seven trains.
  • North of Hitchin may be able to handle another ten trains.

It would appear that the double track section over the Digswell viaduct and through Welwyn North station, limits the capacity of the whole route.

Estimated Timings

In Changes Signalled For HS2 Route In North, I stated this.

Currently, the fastest non-stop trains between London and Doncaster take a few minutes over ninety minutes. With 140 mph trains, I think the following times are easily possible.

  • London and Doncaster – 80 minutes
  • London and Hull  – A few minutes over two hours, running via Selby.
  • London and Leeds – A few minutes less than two hours, running on the Classic route.

For comparison High Speed Two is quoting 88 minutes for London Euston and Leeds, via Birmingham and East Midlands Hub.

There could be a race to Leeds between High speed Two and Classic services on the East Coast Main Line.

Speculation On Extra Services

It would not be right, if I didn’t have a small speculation.

Cambridge Services

Consider.

  • Oxford and Cambridge both have two main routes to and from London.
  • Both have a fast service running at a frequency of two tph.
  • Both have other quality, but slower services.

It could be argued that extra fast services are run to Cambridge, but this would use up two valuable paths over the Digswell viaduct.

Perhaps it would be better to copy Greater Anglia’s solution for London and Norwich services and order a high quality purpose-designed train for the route.

  • 140 mph-capability
  • Digitally-signalled
  • 240 metres long
  • High quality interior

There would need to be some platform lengthening between Cambridge and Kings Lynn.

Leeds Services

Leeds currently has two tph from Kings Cross and Manchester Piccadilly has three tph from Euston.

Leeds also has a daily direct service to Aberdeen.

I suspect that there could be a sorting out at Leeds, which would mean it gets a third service from London.

Conclusion

If something similar to what I have proposed is possible, it looks like as many as an extra seven tph can be accommodated between Kings Cross and the North.

Worcestershire Parkway Station Is Now On The Map

This article on the BBC is entitled Worcester’s New Railway Station’s Set To Open In December.

This Google Map showsWorcestershire Parkway station, at the place, where the Cotswold and Cross Country lines cross.

Services will probably start to call at the timetable change of December 15th, 2019

Judging by the bands of car parking shown in this map, they are expecting a sizeable number of passengers.

I just tried to book a ticket to the station and it is not in the on-line ticketing system yet as a destination, although it does show up as a stop on these journeys.

  • CrossCountry – Nottingham and Cardiff – Hourly
  • GWR – Paddington and Worcestor, Great Malvern and Hereford.- Hourly

Two other hourly CrossCountry services also pass through.

PM Backs Clean Air Law

The title of this post is the front page headline on today’s copy of The Times.

This is the sub-heading of the article on The Times web site.

PM promises binding targets to reduce pollution and praises Times campaign

In a separate box in the paper, which is entitled Our Manifesto, this is said.

  • A new Clean Air Act to confer a legal right to unjpolluted air for everyone in the UK.
  • A ban on new diesel and petrol cars from 2030 and cuts to green car grants to be traversed.
  • Temporary traffic bans outside schools at drop-off and pick-up times.
  • The extension of pre-2016 diesel and pre-2006 petrol pay zones to more cities.
  • Pollution monitors in every postcode to empower people to take action.

How far will Boris Johnson go to meet the manifesto of The Times in the Queen’s Speech on Monday?
