And then, remembering that some trains don't actually go to London
Indeed, I do remember that some trains don't go to London, but I am afraid they are really peanuts in terms of demand compared to the London services.
1tph Sheffield-Newcastle (XC)
1tph Leeds-Newcastle (XC)
1tph Leeds-Newcastle (TPE, thought to increase to 2 with additional paths through Huddersfueld)
1tph Manchester-Glasgow*
1tph-Birmingham-Glasgow*
*and consider demand to run both hourly to Edinburgh as well.
Even if we assume the HSLs to Scotland would have stations at all the places served by XC, TPE, ICWC and ICEC, the more rapid acceleration and higher stop-to-stop speeds made possible by high speed trainsets would enable fewer trains to run while still providing the same level of service at most comparitively minor stations.
You could serve all the East Coast secondary stations currently served by TPE and XC with one or two trains per hour.
Most of these services are run by three or four coach multiple units, are you really suggesting that we give them paths on a line designed for 400m double deck trainsets (or coupled pairs of 200m CC sets).
So let's call that a starting out point of 5tph on the NW arm and 5tph on the NE arm.
5tph is ridiculous, since you can't possibly support demand for 5tph of the szize of trains we are talking about to these places.
Class 185 sized trains have no place on a High Speed Line these days.
plus greater demand for both London-Newcastle, London-Glasgow and London-Edinburgh train travel as the train, at 2.5 hours approx, becomes much faster than air travel on centre-to-centre journeys.
Rail already has the lion's share of the modal share on teh London-Newcastle route and all the air passengers to Glasgow and edinburgh pretty much come to one extra 400m train per hour split between the two, as they would be if you simply ran glasgow trains as extensions of Edinburgh ones.
It's not lunacy to accept that the northern and southern halves of an HSL to Scotland are motivated by different objectives and benefits. The southern half is all about capacity, freeing up paths on already well-used journeys. The northern half is about reducing journey times and encouraging modal shift from road and air to rail travel.
You can't practically convert all the listed services to run on the High Speed Line, and most of them add up to a tiny boost in demand for HS services.
You dilute the intercity traffic that makes the route pay by splitting it over two routes and expect tiny secondary flows, most of which could be captured anyway, to make up the difference.
