Well there is nothing to prevent us creating an easement allowing "Via Interchange" fares that include a ticket on the people mover is there?
No, what I mean is that not many people would change twice to do a journey that can be done directly via the WCML, I don't see a fares problem there.
And to try to sum up a bit of what will Avanti need, and the points brought up in this thread:
- Milton Keynes needs a good LD service, so it seems like it would be wise to stop everything. It also needs good service to Birmingham, Manchester, and keeping the link to Stoke would be good.
- The WCML needs to keep most current direct connections, and to serve the destination without HS2 (North Wales and, from my point of view, Blackpool too, but that's a bit more controversial) in a fast way.
I think that a 5 tph timetable would be best, keeping 2 services to Birmingham (Shrewsbury, as it would otherwise be left with no London service, and Scotland, as the HS2 Birmingham-Glasgow/Edinburgh service will not serve any stations between Wigan and Birmingham. Also, this would allow Wolverhampton to have 2 tph to London), and another three services through the Trent Valley (Chester/Holyhead, which would be the fastest one from MK to Crewe; Blackpool North and Manchester via Stoke-on-Trent; to have 2 tph Crewe in the WCML. As London-Stoke does not have a very big time advantage in HS2, I think the Stoke service should be timed to have effectively 2 tph, one on HS2 and a second on the WCML, the wait for a high-speed service wouldn't be worth the journey reduction in this case.
The other question is how to serve Rugby, Coventry and Nuneaton. (Remember that LNWR will have fasts too): they should probably all get 2 tph: in the case of Coventry, that is self-explanatory, so the Birmingham services would have 3 and 5 calls respectively (MK, Coventry, International; with one calling at Watford and Rugby too). This way, Coventry gets an express. Rugby really can be fitted in anywhere, the fast service (one stop to London) could be the Blackpool North service, with the North Wales one being the Nuneaton fast. This leaves the second Watford stop on the Manchester service, which would have two stops before Stoke, keeping a decent journey time and effectively doubling its frequency.
On timetables, both Birminghams and both Crewes should be roughly separated by 30 minutes, and both Rugby ones too. That means Nuneaton gets both Crewe services. As services should be concentrated to occupy the minimum paths possible, that leaves a service of:
:00 Euston, Milton Keynes, Nuneaton, Crewe, Chester (either hourly or every 2 hours to Holyhead, stops depend on what's better for the North Wales line timetable)
:03 Euston, Watford Junction, Milton Keynes, Rugby, Coventry, Birmingham International, Birmingham New Street, Wolverhampton, Stafford, Crewe, Warrington Bank Quay, Wigan North Western, Preston, Oxenholme, Penrith North Lakes, Carlisle, Lockerbie and (Haymarket, Edinburgh Waverley) or (Motherwell, Glasgow Central)
:30 Euston, Milton Keynes, Nuneaton, Stafford Crewe, Warrington Bank Quay, Wigan North Western, Preston and Blackpool North
:33 Euston, Milton Keynes, Coventry, Birmingham International, Birmingham New Street, Smethwick Galton Bridge, Wolverhampton, Telford Central, Shrewsbury
:36 Euston, Watford Junction, Milton Keynes, Rugby, Stoke-on-Trent, whichever stops to Manchester.
