An interesting point that the ECML might really need 2 main types of services after HS2 opens.
- London to Newcastle/Leeds stopping quite a lot.
- London to Edinburgh/Aberdeen/Inverness calling at York, Newcastle and quite a lot north of Newcastle.
Though this relies on there being a London-Leeds and London-Edinburgh hourly, or ideally 30 minute service. Which the Leeds plans as I understand them will support, but without the western part of phase 2 in full, will be difficult for Edinburgh. I think the join will need to be north of Weaver Junction, and even then daytime freight might need to be reduced or removed from the northern WCML and trains flighted to get; Edinburgh Express (1tph), Glasgow Express (1tph), alternating Glasgow/Edinburgh via Birmingham with more stops in the North West (1tph), various Liverpool/Manchester to Edinburgh Glasgow (2 tph) and work around the various local services using the route between Wigan and Oxenholme. If a reduction in air travel is planned an extra Edinburgh and Glasgow Express each hour is probably called for.
