MP Calling For Borders Link To High-Speed Rail Network
The title of this post, is the same as that of this article in the Southern Reporter.
My feeling is that I don’t think the MP should worry about this one.
Consider.
- When High Speed 2 opens to Crewe in 2027, London to Glasgow trains will take under four hours.
- The West Coast Main Line will be improved between Carlisle and Glasgow.
- Freight traffic between England and Scotland is increasing.
- A large freight interchange could be built at Longtown.
- Increased services between Liverpool/Manchester and Edinburgh/Glasgow are starting.
- Carlisle station is being refurbished.
All this will lead to more through traffic at Carlisle.
I would think it would be extremely likely, that the West Coast Main Line between Carlisle and Longtown will be improved substantially.
If this happens, then any extension of the Borders Railway will have a fast link to HS2 at Carlisle, from where it will probably join the West Coast Main Line in the Longtown area.
It should also be noted, that High Speed 2 is being designed to give benefits to as many places as possible.
A Borders Railway connected to Carlisle fits this strategy.
Should Crossrail Be Extended From Old Oak Common?
In How Will Chiltern Railways Serve Old Oak Common?, I looked at the possibilities of how Chiltern Main Line services will use the Old Oak Common station complex as an additional London terminus to ease the overcrowding at Marylebone station.
In Will Crossrail Go Up The West Coast Main Line?, I looked at why the extension of Crossrail to Milton Keynes was announced and then cancelled as it was thought to be bad value for money.
But is the general principle of extending Crossrail from Old Oak Common onto a new branch or branches a good idea?
Crossrail Revenue And Profit
If you’re running any railway, you get the highest revenue by running as many trains as you can and making sure that they are full with passengers all the time.
The Central Section of Crossrail between Stratford and Paddington stations will be very heavily used, as it will have to handle the following passenger flows.
- Passengers from the Abbey Wood Branch going to and from Central London
- Passengers from Heathrow going to and from Central London
- Passengers from the Reading Branch going to and from Central London
- Passengers from the Shenfield Branch going to and from Central London
- Passengers from National Rail services at Liverpool Street going to and from Central London
- Passengers from National Rail services at Paddington going to and from Central London
In addition it will also be used as an extra Underground line in Central London
The Central Section will be a cash cow for the Crossrail operator!
The various branches to and from Abbey Wood, Heathrow, Reading and Shenfield, may well be less heavily used, but will probably see a different type of passenger to the Central Section, who might need more space and hopefully a seat.
The Class 345 Trains
The Class 345 trains have been designed for efficiency and flexibility.
- I believe that each car is a separate one-car electric train with its own function.
- Most cars will be motored to distribute traction and braking forces along the train.
- I wouldn’t be surprised to see a battery in each car to handle regenerative braking.
- Cars are joined together to make a train of an appropriate length.
- Initially, the trains are starting at seven cars, but will go to nine cars and possibly ten.
- The interiors have been designed to satisfy both needs of a long distance commuter train and a London Underground train.
The operator will be able to configure the trains as new routes are added and passenger levels change.
Comparing Crossrail And The Victoria Line
It is worthwhile to compare the Central Section of Crossrail with the Victoria Line.
Crossrail’s Central Section has the following characteristics.
- Twenty-four trains per hour (tph) in both directions
- Automatic train operation (ATO)
- Full-size trains of up to ten carriages long
- Platform-edge doors
- Large stations with lots of wide platforms and passages.
- Double-ended stations ay Liverpool Street-Moorgate, Barbican-Farringdon, Tottenham Court Road and Bond Street.
- Step-free access
- Easy access to connecting lines
- Cross-platform reverse at most stations
Whereas the Victoria Line has the following characteristics.
- Thirty-six tph in both directions
- Automatic train operation
- Tube-size trains of six carriages
- Small stations with lots of narrow platforms and passages
- Some step-free access
- Some easy access to connecting lines
- Cross-platform reverse at most stations
The two lines show a difference in design, very much in keeping with their construction dates.
One comparison is surprising.
Crossrail is planned to run twenty-four tph through the Central Section, but if Dear Old Vicky can manage 36 tph on a line built in the 1960s with generally cramped stations, surely Crossrail with the benefit of some of the best modern design can do a bit more.
I’ve read that Crossrail could handle thirty tph, but then we wondered in the 1960s at the Victoria Line’s fast trains and high frequency in the twenties between Seven Sisters and Brixton. And look at the old girl now!
Dear Old Vicky is second in frequency to parts of the Moscow Metro, which run a train every 95 seconds, as opposed to the 100 seconds of the Victoria.
I suspect that grates with the engineers of the London Underground, as no-one likes being second.
A few years ago, the engineers thought 33 tph between Brixton and Seven Sisters was the limit but now there is 36 tph all the way along the line.
So will we see further improvements to the Victoria Line like these?
- A loop at Brixton via Herne Hill station to turn trains at the Southern end of the line.
- Higher capacity stations at Oxford Circus, Euston, Kings Cross St. Pancras, Highbury and Islington, Finsbury Park and Walthamstow Central.
- Air-conditioned, walk-through articulated trains
- Full step-free access at all stations and platforms
- Improved train control software
- Improved methods of working
These and other improvements will push the frequency towards the magic forty tph.
Do I think that forty tph is achievable on a line built in the 1960s?
As a Control Engineer, trained in the 1960s, I can only give one answer. And that must be yes!
I feel that the stations are the key, as at times stations like Oxford Circus and Walthamstow Central are struggling to handle the number of passengers. Victoria was like that a few years ago, but the addition of a new entrance and more and wider passages has made the station seem a lot less crowded.
Surely, Dear Old Vicky has shown what is possible, when you take a well designed railway and try to ramp up the capacity!
Various commentators have said Crossrail will handle thirty tph, but why are they not being more ambitious?
Comparing Crossrail And Thameslink
Crossrail and Thameslink have a lot in common.
- Frequencies of twenty-four tph through their central sections
- High capacity step-free central stations
- High-capacity purpose-built trains
- Automatic Train Control in the central sections.
But there are differences.
- Crossrail’s central section is straight through from Paddington to Stratford, whereas Thameslink has a junction at Blackfriars.
- Crossrail’s central section has seven stations, whereas Thameslink has just five.
- Blackfriars station is also a terminal station on Thameslink’s central section.
- Crossrail’s stations are generally island platforms, which ease reversing direction, whereas Thameslink’s generally aren’t.
- Crossrail is 25 KVAC overhead electrification throughout, whereas Thameslink has a voltage change at St. Pancras.
I think that although both lines will be opened at a frequency of 24 tph, raising the frequency on Crossrail will be easier than Thameslink.
The Importance Of Increasing Frequency On Crossrail and Thasmeslink
The train capacity on the two routes are as follows.
- A nine-car Crossrail Class 345 train can carry 1,500 passengers
- A twelve-car Thameslink Class 700 train can carry 1,754 passengers
- A eight-car Thameslink Class 700 train can carry 1,146 passengers
Compare this with an eight-car Victoria Line 2009 Stock train, which holds just 876 passengers.
So if Crossrail went from 24 to 30 tph through the central section, that would add extra capacity for 9,000 passengers per hour, between Stratford and Paddington.
Building Crossrail and upgrading Thameslink will bring London two high-capacity cross-London Underground Lines.
The more the frequencies on those lines can be increased the higher will be the capacity of the Underground network in Central London.
Crossrail’s Shenfield Branch
The Branch to Shenfield station has the following characteristics.
- It is an almost completely separated double-track railway between Stratford and Shenfield.
- All stations will be step-free.
- Most trains on the route will be Crossrail’s Class 345 trains.
- A few of Greater Anglia’s similar Aventra trains may use the route.
- The route will have modern signalling and ERTMS.
- It is proposed that initially twelve tph will serve the branch
I believe the track, stations and signalling of the Shenfield Branch could handle up to twenty-four tph.
That figure might seem high, but consider the following.
- Shenfield station has three platforms where Crossrail trains can be turned back.
- Walthamstow Central and Brixton stations handle thirty-six trains tph with just two platforms.
- The track layout at Shenfield can accommodate through trains.
Passenger access to the platforms is probably more of a limiting factor, than the track and platforms.
Timings
Currently, Class 315 trains are scheduled to go between Stratford and Shenfield in thirty-six minutes, with faster Longer distance services doing the trip non-stop in fifteen minutes.
- Crossrail is claiming on their web site, that the Class 345 trains will do the trip in thirty-two minutes or four minutes less.
- But there are eleven station between Stratford and Shenfield. So that is a saving of only around twenty-two seconds a station.
I feel Crossrail is playing their timings very safe.
Future Services
I think the following will happen in a few years.
- The current proposal of twelve tph to Shenfield will be increased to something like fifteen or twenty tph.
- Crossrail timings between Stratford and Shenfield will approach the current fastest time of fifteen minutes between the two stations.
- Fast services to and from North of Chelmsford will stop at Shenfield to enable faster and easier journeys.
- Crossrail could be extended to stations like Beaulieu and Southend Victoria.
- Shenfield will become a major rail interchange.
The East of England will see major changes to its rail network.
Crossrail’s Abbey Wood Branch
The Branch to Abbey Wood station has the following characteristics.
- It is a tunnelled double-track railway between Whitechapel and Abbey Wood stations.
- All stations will be step-free.
- All trains on the route will be Crossrail’s Class 345 trains.
- The route will have modern signalling and ERTMS.
- It is proposed that initially twelve tph will serve the branch
I believe the track, stations and signalling of the Abbey Wood Branch could handle up to twenty-four tph.
Future Services
I think the following will happen in a few years.
- The current proposal of twelve tph to Abbey Wood will be increased to something like fifteen or twenty tph.
- Services on the Abbey Wood Branch will continue to match those on the Shenfield Branch, as this makes journeys between the two Eastern branches easier.
- Crossrail could be extended to stations like Ebbsfleet and Gravesend.
- Abbey Wood will become a major rail interchange.
South East London and Kent will see major changes to its rail network.
Summing Up The Two Eastern Branches
The two Eastern Branches can probably provide as many as twenty-four tph for Crossrail.
As the maximum frequency through the Central Section is probably in the thirties, they can allocate services according to where the traffic lies.
It would also appear that as the two services will use the same platforms at Whitechapel station and trains will be every few minutes, that Crossrail is designed to make journeys between say Ilford and Abbey Wood much quicker than by car.
Crossrail’s Reading Branch
The Branch to Reading station has the following characteristics.
- It is a semi-separated double-track railway between Paddington and Reading.
- All stations will be step-free.
- Most trains on the route will be Crossrail’s Class 345 trains.
- Other services may share the tracks.
- The route will have modern signalling and ERTMS.
- It is proposed that initially six tph will serve the branch; four to Reading and two to Maidenhead.
I believe the track, stations and signalling of the Reading Branch could handle up to twenty-four tph,
Future Services
I think the following will happen in a few years.
- The current proposal of six tph to Reading and Maidenhead will be increased increased.
- Crossrail could be extended to stations like Basingstoke and Oxford.
- Reading will become an even more major rail interchange.
West London and Berkshire will see major changes to its rail network.
Crossrail’s Heathrow Branch
The Branch to Heathrow has the following characteristics.
- It is a fully-separated double-track railway between Airport Junction and Heathrow.
- All stations are step-free.
- Most trains on the route will be Crossrail’s Class 345 trains.
- Other services may share the tracks.
- The route will have modern signalling and ERTMS.
- It is proposed that initially six tph will serve the branch.
I believe the track, stations and signalling of the Heathrow Branch could handle in excess of twelve tph.
Future Services
I think the following will happen in a few years.
- The current proposal of six tph to Heathrow is increased.
- Crossrail could be extended to stations beyond Terminal 5.
- Heathrow Express will fade away.
Heathrow will see major changes to its rail network.
Turning Back Crossrail Trains At Paddington
These services will call at Paddington from the East.
- 12 tph from Abbey Wood
- 12 tph from Shenfield
And these from the West
6 tph from Heathrow
2 tph from Maidenhead
4 tph from Reading
This gives an imbalance, so twelve tph will have to be turned back to the East at Paddington.
Crossrail Services
The provisional service pattern is shown in the Wikipedia entry for Crossrail under Services.
It effectively shows the following services, with times are from Crossrail’s provisional journey time calculator.
- 4 tph – Reading to Abbey Wood – 80/78 minutes
- 2 tph – Maidenhead to Abbey Wood – 67/66 minutes
- 4 tph – Heathrow Terminal 4 to Abbey Wood – 60/60 minutes
- 2 tph – Heathrow Terminal 5 to Abbey Wood – 60/60 minutes (assumed same as previous)
- 12 tph – Paddington to Shenfield – 51/51 minutes
It should also be noted that Paddington to Abbey Wood is 29/28 minutes.
Note.
- The first figure is for the West to East journey.
- The second figure is for the East to West journey.
- There isn’t much difference between West to East and East to West journeys.
This leads me to give these numbers for the trains on each route.
- Reading to Abbey Wood – 12 trains
- Maidenhead to Abbey Wood – 5 trains
- Heathrow Terminal 4 to Abbey Wood – 10 trains
- Heathrow Terminal 5 to Abbey Wood – 5 trains
- Paddington to Shenfield – 24 trains
This totals up to 56 trains.
Note.
- My numbers of trains figures, are very rough and are minimum numbers.
- Provisionally, Crossrail will also be running 4 tph between Liverpool Street and Gidea Park in the Peak, which could need four trains.
- Crossrail have ordered 70 trains.
- Some trains will be in maintenance and others will be held in reserve.
Crossrail seem to have ordered a sensible number of trains for the initial services.
Ceossrail Extension To Gravesend
It would appear that a typical Abbey Wood to Gravesend service takes just under half an hour.
This is with slower twenty-five year old Class 465 trains, so extending services to Gravesend would just add an hour to the round trip.
This would make train timetabling easy.
If the Heathrow Terminal 4 service to Abbey Wood was extended to Gravesend, it would require another two trains.
In addition.
- The Class 345 trains have been designed to run on 750 VDC third-rail electrification, with the addition of third-rail shoes.
- I think that the new track layout at Abbey Wood station could cope with four tph running to Gravesend using the North Kent Line.
- A single platform at Gravesend could turn back four tph.
It does look that to choose Gravesend as an extension for Crossrail could be a very good decision.
The New South Eastern Franchise
This will be a key factor in extending Crossrail to Gravesend and I suspect all bidders will give co-operation with Crossrail, a high priority.
I suspect a new franchise will replace a large proportion of the train fleet with new 100 mph traqins and that the Class 465 trains will be retired.
The new franchise is due to start in December 2018.
When Could A Crossrail Service To Gravesend Start?
I believe that the following infrastructure is ready for a four tph Crossrail service to Gravesend.
- The link between Crossrail and the North Kent Line at Abbey Wood station.
- Platform 0 at Gravesend is a twelve-car London-facing bay platform, that could handle the trains.
- Dartford, Gravesend, Greenhithe stations are step-free.
However, certain things must happen before a Crossrail service to Gravesend could start.
- The new Southeastern franchise must be up and running.
- ERTMS must be installed along the North Kent Line.
- All trains running along the North Kent Line must be 100 mph trains, able to take advantage of modern signalling.
- All stations between Abbey Wood and Gravesend must be made step-free.
The new franchise will probably have its new service pattern and modern trains in place by the end of 2023, which would probably make the Crossrail extension easier.
Before a decision is made on the extension, Crossrail needs a couple of years to find out how passengers use the new line and the other services, which will include Thameslink, that call at Abbey Wood station.
Can Crossrail Be Extended From Old Oak Common?
Before answering the question, the related question of whether it is possible should be answered.
Extending Trains From Paddington
Current proposals envisage twelve trains turning back at Paddington.
It would not be difficult if a number of these trains continued to Old Oak Common station.
Can Paddington To Old Oak Common Handle The Extra Trains?
The current proposals envisage just twelve tph using the route between Paddington and Old Oak Common station, with perhaps a few wxtra trains going to and from Old Oak Common Depot.
As the tunnelled section of Crossrail can handle double that frequency, I suspect there will be no problems extending extra trains to Old Oak Common station.
It would appear that there would be no problems extending services to Old Oak Common station.
Where Would The Extra Services Go?
The choices lie between the Chiltern Main Line and the West Coast Main Line.
If we take Crossrail’s well-thought out choice of Gravessend, I think we need a destination, that is ideally just under thirty minutes from Old Oak Common station.
In the next few sub-sections, I’ll look at possibilities.
Extending To High Wycombe On The Chiltern Main Line
A service between High Wycombe and Wembley Stadium stations takes 27 minutes with stops at Beaconsfield, Gerrards Cross and South Ruislip stations. Taking the Acton-Northolt Line and even with stopping at Seer Green and Jordans, Denham Golf Club, Denham, West Ruislip and Greenford, I’m pretty sure, that a train could go from Old Oak Common to High Wycombe and back in comfortably under an hour.
Four tph between High Wycombe and Shenfield would require twelve trains, which is four more than would be needed for the same service between Paddington and Shenfield.
Consider.
- Four tph could easily be turned back in a single platform at High Wycombe station.
- High Wycombe station has plenty of space.
- However, it would need the route between Old Oak Common and High Wycombe to be electrified.
- But, it is a long-term aim of Chiltern Railways to electrify the Chiltern Main Line.
I believe that High Wycombe station could be a viable terminal for Crossrail.
Extending To Milton Keynes Central On The West Coast Main Line
A service between Milton Keynes Central and Wembley Central stations takes 51 minutes with seven stops.
This would mean that a train could go from Shenfield to Milton Keynes Central in comfortably under two hours.
Four tph between Milton Keyns Central and Shenfield would require sixteen trains, which is eight more than would be needed for the same service between Paddington and Shenfield.
Consider.
- Four tph could easily be turned back in a single platform at Milton Keynes Central station.
- Milton Keynes Central station has space for a terminal platform.
- Except for creating the connection at Old Oak Common and updating stations to full step-free access, the infrastructure is pretty good.
- Crossrail would be linked to the East-West Rail Link.
I believe that Milton Keynes Central station could be a viable terminal for Crossrail.
Should Crossrail Be Extended From Old Oak Common?
It is certainly possible to extend to either High Wycombe or Milton Keynes Central.
If a decision were to be made to extend Crossrail, passenger statistics would probably decide, which would be the extra terminal or terminals.
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!
Was It Just Bad Value For Money?
Wikipedia says this.
This proposal was shelved in August 2016 due to “poor overall value for money to the taxpayer”
But it was BC (Before Covid)!
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 Midlands 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 carto.map.free.fr, which shows the lines in the Old Oak Common area.
Note.
- 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.
Note.
- 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.
Note.
- 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 built 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 signalling and a degree of Automatic Train Control, eight tph each way could be handled on a single track.
Conclusion
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?
Slow Trains In The North
I was asked a few hours ago, as to why would TransPennine Express want to get rid of their Class 350/4 trains.
These ten 110 mph trains were only delivered in 2013 -2014, so why should TransPennine Express replace them?
They work Manchester Airport to Glasgow and Edinburgh services, but they have two major problems.
No Wi-Fi
It looks like none of the Class 350 trains have wi-fi, so possibly passing them on now3, will give that problem to the new owner.
They Are Only 110 mph Trains
The trains are being replaced with Class 397 trains from Spanish manufacturer; CAF.
I suspect the Class 397 trains have a few advantages over the Class 350 trains.
- The new trains are probably built with wi-fi.
- The interiors are custom-designed for the Scottish and Manchester Airport markets.
- The trains are five-cars as opposed to four.
- The capavity of the new trains is 286 seats as opposed to 229.
But the major difference is that the Class 397 trains are 125 mph trains, like the Class 390 trains used by Virgin.
Looking at times between Glasgow and Preston on the West Coast Main Line, it would appear that the Class 390 trains are up to twelve minutes faster than the current Class 350 trains, so when both companies are running 125 mph trains will we see an improvement in both?
Similar improvements will probably happen on the East Coast Main Line, where the Class 397 trains will be mixing it with Class 800 trains.
Could The Class 397 Trains Handle 140 mph?
This question has to be asked, as at some point in the next few years, when the signalling allows, there may be possibilities for 140 mph. running on both the West and East Coast Main Lines.
I would hope that the Class 397 trains can be uprated to allow 140 mph running.
Will The Class 397 Trains Get In The Way Of HS2 Trains?
HS2 could reach Crewe as early as 2027 and the trains will take to the West Coast Main Line to go North.
I hope that the Class 397 trains are future-proofed to share a line with these new trains.
Other Trains On The West And East |Coast Main Lines
There are other trains that will use the West and East Coast Main Lines, which will not be able to operate at speeds in excess of 125 mph.
- 100 mph Class 185 trains
- 125 mph Class 220 trains
- 125 mph Class 221 trains
- 100 mph Class 319 trains
- 125 mph InterCity 125 trains
I suspect these trains will have to be kept away from the two main lines to Scotland.
Conclusion
The Class 397 trains will have to be capable of being uprated to 140 mph.
I also suspect that any train not capable of holding 140 mph may not be allowed on the West and East Coast Main Lines.
Enthusiasm For The Borders Railway In Carlisle
This article in the Carlisle Express And Star is entitled New Rail Link To Carlisle Could Be ‘Catalyst’ For Job Creation.
It is discussing the report of the Campaign for a Borders Railway, which recommends rebuilding the line.
This is said in the newspaper.
The summary said: “A new rail link to Edinburgh via the Borders could be a catalyst for the development of new employment uses on the former MOD land at Longtown and in the Kingstown area on the northern fringe of Carlisle.
“Park and ride stations in these areas would provide congestion relief and improve access to the city.
I think that as the only major City on the route, apart from Edinburgh, Carlisle must be a major beneficiary of a reinstated Borders Railway.
Carlisle scores high in the Location, Location, Location stakes, as not only is it just off the M5 between England and Glasgow, but Carlisle Citadel station is a major rail interchange. Incidentally, these romantic Victorian names are dropped far too readily.
This map from Wikipedia, shows the railways around the City.
Note Longtown station on the Waverley Route to Edinburgh and the MOD Depot or Defence Munitions Centre Longtown, between the two rail routes, to the North of the map.
This Google Map shows the DMC.
Note the West Coast Main Line with its connection to the Centre and the Glasgow South Western Line branching off to Gretna Green station and all the way to Glasgow.
Longtown is in the North East corner of the map and you can just pick out the track-bed of the Waverley Route, linking the town to Carlisle.
Conclusions
The CBR report, recommends a Park-and-Ride at Longtown and I wonder, if developments there might be the key to rebuilding the Waverley Route on a more economic basis.
A lot would depend on whether the Defence Munitions Centreat Longtown continues to be used, but the following could be built in the area.
- The proposed Park-and-Ride.
- A Strategic Rail Freight Interchange.
- Distribution warehouses.
- Factories that need lots of space and good rail and road access.
A lot would depend on what the locals want and whether Scotland became independent, for which the site must be ideally placed.
If the track-bed of the old Waverley Route is still present and can be used to Carlisle, this route could be developed as a rail route, which might have advantages.
- It has its own route to Carlisle station with a separate bridge over the River Eden.
- The West Coast Main Line bridge over the River Eden appears to be only double-track.
- Would it improves timings to and from Glasgow on the West Coast Main Line?
- Could it be used as a diversion route for freight trains on the West Coast Main Line through Carlisle?
- Extra stations could be opened on the route, that could improve connectivity in the City
- There is probably few paths on the West Coast Main Lines for extra trains from Longtown and/or a reinstated Waverley Route to Edimburgh.
But would the extra cost be justified?
Done properly, as the CBR report says, improving the railways between Carlisle and a new Park-and-Ride at Longtown, would surely improve the Carlisle economy.
Birmingham Airport Mulls Plan For Terminal Inside HS2 Station
This is the title of an article in Construction News.
This Google Map shows Birmingham Airport, the current Birmingham International station, the NEC, with the M42 Motorway going North-South down the Eastern side.
Currently, it is planned that the Birmingham Interchange station for HS2, would be on the other side of the M42 to the NEC.
Surely, the Construction News headline is indicating that something better can be done.
In an ideal world, Birmingham Airport would have one station for HS2, West Coast Main Line and local train and tram services, with a step-free lift/escalator connection between all platforms and both Departures and Arrivals at the Airport.
Will High Speed 2 Have Go-Anywhere Trains?
I ask this question as after writing Plans For Toton Station For HS2 Are Beginning To Emerge, I started to think about the specification of the trains that will work on HS2.
Extending North |From Toton Or East Midlands Hub Station
Extending HS2 to Sheffield from Toton will eventually be via a dedicated High Speed Line, where the trains can run at their design speed of 225 mph.
But Toton HS2 to Sheffield via Chesterfield will be linked by the Erewash Valley Line, where trains will be able to travel at least as fast as 125 mph.
The Erewash Valley Line will probably be electrified before HS2 opens to Toton HS2 around 2030, to bring Sheffield consistently under two hours from London.
Extending North From Crewe
Similarly Crewe to Liverpool will not be getting a dedicated High Speed Line, but there is already a route where at least 125 mph is possible.
As passengers won’t want to change trains, Liverpool will get two trains per hour (tph)from London on HS2.
The only work needed North of Crewe would be to create extra and longer platforms at Liverpool Lime Street, provided that the new HS2 trains can work on classic high speed lines like the West Coast Main Line.
These improvements at Liverpool Lime Street are actually underway and knowing Scousers as I do, you could bet your house on it being ready in 2027, as they would want to have HS2 services at the same time as Manchester, if not a couple of years before.
Learning From The French
We should also look at how the French do things.
If you travel from Biarritz to Paris via a TGV, the service runs on both High Speed and classic lines.
From the Liverpool and Sheffield examples, I suspect that we will adopt a similar philosophy.
Consider when HS2 opens, the places that could be served directly from Crewe.
- Runcorn and Liverpool
- Manchester Piccadilly, if there is platform space.
- Warrington, Preston, Carlisle, Glasgow and Edinburgh – Why not?
- Chester and Holyhead – If the North Wales Coast Line is electrified, as has been threatened!
Note most of the West Coast Main Line routes are covered.
Can this explain the decision to combine the HS2 and West Coast Main Line franchises and the early extension of HS2 to Crewe?
The new franchise could even use the same 225 mph trains for HS2 at a slower speed on the West Coast Main Line to replace the Pendelinos.
The only disadvantage would be that the new trains couldn’t take advantage of the more generous HS2 loading gauge, unless of course the classic lines, where they are to run have their gauges enhanced. This may already be the case, as many of these routes have a loading gauge of W10 to take large freight containers.
The Trains For HS2 And West Coast Main Line
I think we’ll be seeing a very interesting specification for the HS2 trains.
- 225 mph capability on High Speed Lines
- 140 mph Pendolino performance on classic lines where possible.
- Short and long trains. Class 800 trains and others seem to be ordered this way, as five and nine/ten car units.
- Automatic coupling and uncoupling of units, just as Class 395 trains do now!
As the trains won’t be delivered for nearly ten years, wouldn’t be surprised to see that they have a 100 mph independently-powered capability of perhaps 100 miles. This would enable the trains to reach places like Aberdeen, Barrow in Furness, Blackpool, Inverness and Lincoln from the West Coast Main Line or Phase 1 of HS2.
Expanding The High Speed Network
It may seem strange to use perhaps onboard energy storage to extend services away from HS2. But this capability would probably only be given to the shorter trains that can join and split at Crewe or Birmingham International for fast running to and from London. Generally, when operating on onboard energy storage, the trains will be travelling at slower speeds. so less energy is needed.
This would mean that places like Barrow-in-Furnace, Blackpool, Cleethorpes and Lincoln could be easily added to the high speed network.
The High Speed network could also be expanded by improving the current network with selective electrification and the capability for higher line speeds.
All of these improvements on the classic lines, would mean that local and freight trains were able to provide a better service too!
Coupled with HS2, they would make a wonderful marketing opportunity.
I estimate the following using new trains and HS2 from Crewe, when Phase 2a of HS2 is complete.
- Glasgow-London would take under four hours for the journey as opposed to just over four and a half hours now.
- Liverpool-London would come down from two hours twelve minutes to one hour 33 minutes.
- Preston-London would down from two hours fifteen minutes to under a hundred minutes.
- Wigan-London would come down from just over two hours to just 87 minutes.
And some commentators and politicians doubt HS2 is needed.
Conclusion
Certainly, the decision to extend as fast as possible to Crewe was a very good idea.
Consider going from Euston to Glasgow in say 2028.
- The train would run from Euston to Crewe at full speed of 225 mph stopping if required at Old Oak Common and Birmingham International in a time of 58 minutes.
- From Crewe to Glasgow, the train would run at least at 125 mph stopping as appropriately.
- Selective improvements and in-cab signalling would reduce journey times from those of today to the North of Crewe.
Ten years or so later, the journey time will be even faster as the High Speed line was extended past Crewe.
Seamless Interchangeability
At several places on the UK rail network, two trains running as a pair will split, with one train going to one destination and another going to another.
I wrote about trains splitting and joining in Trains Uncoupling and Coupling at Cambridge.
In the past, UK railways used to use the concept of slip coaches, so that coaches could be dropped from an express without stopping. But the last time it was used in the UK was in September 1960 at Bicester North station.
I have just read this article on the Rail Engineer web site, which is entitled Seamless Interchangeability.
The article talks about a concept of dynamic coupling, where trains are automatically coupled and uncoupled at line speed.
It also talks about the issues this would raise.
As a Control Engineer, I’m fairly certain, that it would be very easy to create a system, where say an eight-car Kings Lynn train could split just before Cambridge station, with the front four-car train going to Kings Lynn and the other four-car train stopping in Cambridge station.
It could either be done using two drivers or by driver-less trains. Although the unions would have a lot to say about the latter.
I also believe that if the trains could uncouple, then coupling at line speed would also be possible.
So what is the point?
An Example From The Brighton Main Line
To make full use of the capacity available, Southern serve Littlehampton and Ore, with a train that divides at Haywards Heath. It is a well-proven technique that has been used for decades.
Automatically splitting the two trains at line-speed, can give journey time advantages.
Take the 19:47 from Victoria, which arrives at Haywards Heath at 20:30 as an example.
The following is taken from the timetable.
- The front portion to Ore leaves at 20:34.
- The rear portion to Littlehampton leaves at 20:36.
- Stops at East Croydon and Gatwick Airport take about a minute.
This leads to the following, if the two trains split immediately after stopping at Haywards Heath and before the trains take different directions after Keymer Junction where the East Coastway Line divides from the Brighton Main Line, a few miles South.
- The Ore train performs a one-minute stop instead of one of four minutes, thus saving three minutes.
- The Littlehampton train performs a one-minute stop instead of one of six minutes, thus saving five minutes.
- The platform at Haywards Heath is only occupied for a minute, as opposed to six.
- The Littlehampton and Ore portions must be capable of providing enough capacity for their route.
For those worried about driver-less trains, the driver of the second train for Littlehampton, would probably step up at the previous stop at Gatwick Airport or at Haywards Heath.
But the outcome would be a small increase in capacity on the line, due to the platform at Haywards Heath being occupied for five minutes less.
Coming North, take the 09:47 from Littlehampton as an example.
The following is taken from the timetable.
- The first train arrives at Haywards Heath at 10:35 and leaves at 10:45.
- The second train arrives at Haywards Heath at 10:41.
The pattern of the trains would be different.
- Whatever was the front portion of the train would go through Keymer Junction first
- The train forming the rear portion would be the next train through the junction.
- The rear portion could catch the front portion and the two trains would be automatically coupled together before Haywards Heath.
- The joined train would stop at Haywards Heath for a minute.
- The driver of the second train could step-down at Gatwick Airport or Haywards Heath.
In some ways the mathematics involved in the coupling, are not unlike those for a fighter jet connecting with a tanker aircraft. Except that speeds are a lot lower and there is no need to control direction only closing speed.
Haywards Heath station would be occupied for up to nine minutes less, thus creating capacity.
This simplistic analysis, shows how automatically coupling and uncoupling trains at line speed can create capacity and decrease journey times.
- Journey time from Victoria to Ore would be reduced by three minutes.
- Journey time from Victoria to Littlehampton would be reduced by five minutes.
- In the Down direction the platform at Haywards Heath station would be occupied for just one minute instead of six.
- Journey time from Littlehampton to Victoria would be reduced by nine minutes.
- Journey time from Ore to Victoria would be reduced by three minutes.
- In the Up direction the platform at Haywards Heath station would be occupied for just one minute instead of ten.
Obviously strategies would have to be developed for various eventualities including.
- Unsuccessful coupling or uncoupling.
- Late trains.
- Signalling and train failures.
- Leaves on the line.
- Extreme weather.
But as during all coupling and uncoupling operations, both trains would have a driver in the cab, keeping an expert eye over the procedure and each train could be driven independently, I think all safety issues could be overcome, to the satisfaction of all parties.
If you read the full article, you’ll see that there are some much more exciting possibilities, than the simple ones I have outlined here.
But I do believe that line speed uncoupling and coupling of trains with a driver in the cab of both trains involved, can be a very powerful tool in creating capacity on the UK’s railways.
The Great Eastern Main Line
I know the Great Eastern Main Line well and several trains are coupled and uncoupled regularly on this line.
As Greater Anglia has ordered new five-car Aventra trains and nearly all platforms can take 12 -car trains, running these trains in pairs and coupling and uncoupling appropriately, is probably in their plans for the line.
As on the Brighton Main Line, could coupling and uncoupling at line speed, unlock capacity on the line?
A few weeks ago, I caught a train from Chelmsford to Manningtree, that divided at Colchester, with the front four-car train going to Clacton and the rear four-car train going to Harwich.
The 16:44 from Liverpool street is a train that divides at Colchester, when it arrives at 17:40. These timinings are from the timetable.
- The Clacton portion of the train leaves at 16:44.
- The Harwich portion of the train leaves at 16:47.
As the Sunshine Coast Line for Clacton leaves the Great Eastern Main Line immediately after Colchester station, it would appear that the two trains must uncouple during the stop at Colchester.
Surely, an improved and well-designed automatic uncoupling system could separate the trains faster, saving minutes on both services.
Towards London, two trains leave Harwich and Clacton at 07:16. The timetable shows.
- The Harwich train arrives at Colchester at 07:47 and leaves at 07:54.
- The Clacton train arrives at Colchester at 07:50 and leaves at 07:54.
Surely, an improved coupling system, could join the trains faster, saving minutes on both services.
The time savings will not be as great as those at Haywards Heath, but automatic coupling and uncoupling must be a worthwhile feature of the new trains.
|As Bombardier are adding automation to the Aventra, could they be adding the ability to automatically couple and uncouple trains, both in the station and at line speed?
The West Coast Main Line
I have seen Class 221 Trains, join at Crewe, but I don’t think this is done any more.
However, with the need for direct services from London to places like Blackpool, Burnley and Huddersfield, the ability to be to couple and uncouple trains quickly must be something that would be useful to make optimal use of the valuable train paths on the line.
The East Coast Main Line, Midland Main Line, Great Western Main Line And South West Main Line
If the West Coast Main Line could benefit, then surely these lines could as well.
Class 800/801 Trains
The Class 395 train is very much related to the Class 800 and Class 801 trains, that are being built by Hitachi for the East Coast Main Line, Great Western Railway and other routes.
In The Impressive Coupling And Uncoupling Of Class 395 Trains, I talked about the design of the coupling system for the Class 395 trains.
I would be very surprised if this feature was not incorporated in the Class 800 and Class 801 trains.
So will we be seeing two five-car Class 800/801 trains dividing and joining at a convenient station and then running as a ten-car train to and from London?
Class 385 Trains
What about the Class 385 trains for Scotland?
- These are another version of Hitachi’s A-Train, like 395s, 800s and 801s.
- These will come in two lengths; three-car and four-car.
- Edinburgh-Glasgow services will need at least two units to be coupled together.
- The trains are being introduced from Autumn next year.
It seems to me, that Scotrail are acquiring a very flexible fleet that can run in various lengths.
Will they have the ability of the 395s to couple and uncouple in under a minute?
And if they do, will Scotrail use this ability to adjust train formation to the traffic?
Aventras
There are three definite orders for Bombardier’s new Aventra train at the present time.
- Class 345 trains for Crossrail.
- Class 710 trains for London Overground.
- Five and ten car units for Greater Anglia.
All trains are fixed formations in a mixture of lengths.
Will Aventras have similar coupling and uncoupling performance to Hitachi’s Class 395 trains?
I suspect normally, the Crossrail trains will never be coupled together, as where are platforms for a four-hundred metre long train?
But suppose a train fails in the central tunnel, will the quickest way to remove it, be to attach it to another train and drag it out?
The routes where the London Overground trains will run, are currently served by a mixture of four-car and eight-car trains. So will London Overground, adjust train length to the known traffic patterns?
Greater Anglia do couple and uncouple trains at present to serve Harwich. So I suspect, we’ll see use of an automatic and fast coupling and uncoupling feature to create a more efficient timetable.
Cross City Lines
There are several cross-city lines in the UK.
- Cross-City Line – Birmingham
- Crossrail
- North Berwick Line – Edinburgh
- Northern Line – Merseyrail
- Snow Hill Lines – Birmingham
- Thameslink
One of the characteristics of cross-city lines, is they are busiest in the centre of the city, where passengers tend to use the trains for short hops , as well as longer distances. Then in the suburbs, outside of Peak hours the trains could run almost empty.
Crossrail’s trains are designed so that hopefully they could cope with the variable traffic, but would it be possible to have half trains, which join and split at outer stations.
Thameslink
I think that Thameslink could be the line that might benefit most, as it would probably want to serve more places.
In All Change On Thameslink, I detailed the current proposed schedule of trains.
- 4 trains per hour (tph) – Sutton to St. Albans (2 tph via Wimbledon, 2tph via Mitcham)
- 2tph – Brighton to Bedford
- 2 tph – Three Bridges/Gatwick Airport to Bedford
- 2 tph – Brighton to Cambridge North
- 2 tph – Horsham to Peterborough
- 2 tph – Maidstone East to Cambridge
- 2 tph – Sevenoaks to Blackfriars
- 2 tph -Orpington to Kentish Town/West Hampstead
- 2 tph – Rainham to Luton (via Dartford and Greenwich)
- 2 tph – East Grinstead to Bedford
- 2 tph – Littlehampton to Bedford
This makes a total of twenty-four tph, which is the design limit for the central tunnel.
In this schedule 4 tph go to Cambridge and 2 tph go to Peterborough. Suppose, it was decided that Peterborough needed 4 tph.
The path limit of 24 tph through the central tunnel makes this impossible, but if Peterborough and Cambridge services joined and split at perhaps Stevenage, then both Cambridge and Peterborough would get 6 tph through the core tunnel.
It would need new six-car trains, that could couple and uncouple quickly.
Conclusion
I believe that improving the coupling and uncoupling of all modern trains to the standard of that of the Class 395 trains could be very beneficial, to train operators, staff and customers.
If coupling and uncoupling could be done at line speed, this might bring extra benefits.
