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.

  1. TGV Atlantique did this (25 years ago 😦 ) ran at 300kmph to Le Mans and then 200kmph on normal rail to Nantes and other cities. TGV section since extended.
