I've had an idea for a theoretical high speed railway system that has been percolating in my mind for the past err...very long time - which I will now share with you all. Stop groaning in the back.
First of all, this is entirely a thought experiment, so before you turn up at my house with pitchforks demanding to know "Where's the funding coming from!?!" The answer is going to simply be "magic" - it's simply "in a perfect world exercise".
So first of all, I'll get rid of the current numerical method of naming our high speed rail lines (HS1, HS2) etc - purely as a branding exercise to get past the whole HS2 debacle. Instead, I'd give them wishy washy names. For example, HS1 will be renamed "High-Speed Southern England", which I think has some bite to it.
So the first route I would build would not be London to Birmingham, but "High Speed Metropolitan" (that name needs some work).
HSM would essentially run from an underground junction on HS1 somewhere under Canonbury, to a Euston Cross station, through Old Oak Common and out to Heathrow as per the old Heathrow Hub HSR routing. From LHR, it would then either run to Woking to connect onto the SWML or down the M3 to connect with the SWML at Basingstoke.
This line would take the Javelin services away from St. Pancras and continue them onto the SWML via Heathrow in a sort of Uber-Thameslink. Whilst it would link up Heathrow with Hampshire/Surrey/Dorset by rail, as well as Kent, it'll feed in those areas directly onto the main-northern HSR spine via Birmingham at OOC - which I'll christen "High Speed North West" (a bit more limp that name).
High Speed North West is essentially HS2, but running in full to Manchester Victoria (through station) via another through station at Birmingham Moor Street. In this scenario, London to Manchester trains will stop at my new Moor Street high-speed station. The goal would be to have as high a load factor as possible for each train by providing the premier London-Birmingham-Manchester service as well as important regional links that will act as feeder services to the HS route. So for instance:
OOC will connect with trains from the South West
Moor Street will be the hub for passengers coming from Bristol/Cardiff
New HS regional routes from Birmingham to Nottingham and Oxford will also connect with the London to Manchester services.
I envision this route alone would have 6tph - a train from London to Manchester every 10 mins. The purpose of this is largely a psychological one, to demonstrate that the core cities of the nation can be traversed as if it were a rapid transit route. Barely any waiting at all, ticketing done entirely through contactless payments. And a near predictable stopping pattern. Aside from 1 or 2 an hour that will call at Birmingham Airport. 6tph from Birmingham to Manchester Airport would also connect a metropolitan region of almost 3 million people in with an airport about 20 mins from the city centre - a game changer for regional productivity.
A transpennine line from Liverpool to Leeds via Bradford would of course be built, as well as the Eastern "Y" arm (along with a Manchester to Sheffield high speed line). Again, this would link Liverpool, Leeds, Hull, Sheffield and Newcastle straight into Manchester Airport with frequent HS trains. The airport would undoubtedly become the UK's second national hub - bolstering Manchester's profile as a European commercial hub.
The next grand line would be "High Speed Caledonia" (again, needs work), a line from the Manchester Airport area to the Central Belt. Aside from London services, this line would accommodate regional services from:
Liverpool/Manchester - Manchester Airport (combine) - Preston Glasgow/Edinburgh
Nottingham - Sheffield-Manchester-Manchester Airport-Preston-Glasgow Edinburgh
But again, the beauty of a through station at Birmingham is that London to Scotland services could call there to pick up passengers coming in from Bristol/Wales/East Midlands to help bolster the passenger numbers. In threads regarding high speed 2's potential extension to Scotland, there's always a bit of ambiguity over whether such a route would attract enough passengers from London to make it worthwhile. But with my system, a London to Scotland line would also efficiently soak up passengers from Southampton's Metro area as well as the Bristol/Cardiff Metro area into one train. I envision with such a system, a half-hourly London to Scotland service could be entirely plausible.
When a high speed line from Birmingham down to Bristol and the South West inevitably is planned, I imagine these trains would exclusively serve the North East axis. Again, this would be to funnel as much passengers as possible onto London to Manchester/Scotland trains. Birmingham Moor Street High Speed would be designed to be as interchange friendly as possible from the start.
Oh and of course a London to East Midlands HS Line running via the M11 corridor - allowing Cambridge to Heathrow regional services.
Anyway this is a potential, comprehensive high speed rail system for the UK, not scoped for increasing capacity on the WCML south, but to aggressively boost national productivity as much as a single mode of transport can do. Obviously you'd need a huge upgrade to local, regional and rapid transit rail system to feed into the HS and lastly distribute passengers around the Metro Areas of their destinations. So it would be an entire package of rail investments rather than just a single HS line.
Rolling Stock
I imagine due to the possible high loadings on London to Manchester trains, you'd need as high capacity trains as possible. I would specify for this route double decker trains, if possible. Using the previous Shinkansen Max double decker trains, a quick calculation confirms that by using that 8 car train as a template and doubling the length, a unit of over 1,600 seats could be produced at roughly 400 meters long. I do not know whether it would be possible to accelerate such a large and heavily loaded train to speeds of up to 225 mph as quickly as a single decker train, but I imagine it would need incredibly powerful traction motors regardless.
I would also, invest several billion into a High Speed Rail Rolling Stock Research Centre, so that such trains could be designed at built in Britain. Stimulating a British production line for high-speed rail vehicles for export for further HS lines across the globe.
Anyway, if at least one person likes the idea, I will be pleased. Back to the real world...
