“HS2 on existing track” is not a thing. The whole point of it is to move long distance trains off existing track so more local trains can run.
With this half arsery, the Tories get the worst of both worlds: they spend most of the money and get pretty much none of the benefit.
@goatsarah 125mph top speed, average possibly 100 mph. Been doing that on the old Western Region for decades
@JohnLoader6 People need to stop thinking about the speed. HS2 is, and always was, designed to separate mainline and local traffic. That's what it's for.
It was envisaged as an LGV because that's what you do these days. There's no point building a new intercity line at less than LGV spec.
@goatsarah In theory both the East and West Coast main lines were upgraded to 140mph - hence tilting trains. They weren't. Welwyn viaduct needs a by pass - 2 tracks in the middle of a four track network ridiculous
@goatsarah @JohnLoader6 build another nice looking brick viaduct next to it?
@goatsarah there is also the problem of a station at one end blocking the tracks on stopping trains
@ajlanes The four track also stops at Northallerton going North from York, a heavily used route but there were plans to add a third line and platform as a short loop for stopping trains there. But trains towards Teesside have to cross both main lines
