Anyway, for the West Coast franchise, this would be my proposal:
xx.03 Manchester Piccadilly
Rugby, Coventry, Birmingham International, Birmingham New Street, Wolverhampton, Stafford, Stoke-on-Trent, Stockport
xx.07 Liverpool Lime Street
Milton Keynes Central, Nuneaton, Crewe, Runcorn
xx.10 Chester
Watford Junction, Tamworth, Crewe
xx.13 Northampton
xx.20 Manchester Piccadilly
Milton Keynes Central, Stoke-on-Trent, Macclesfield, Stockport
xx.23 Wolverhampton
Watford Junction, Coventry, Birmingham International, Birmingham New Street, Sandwell & Dudley
xx.30 Glasgow Central
Preston, Lancaster, Oxenholme/Penrith, Carlisle
xx.33 Liverpool Lime Street
Stafford, Runcorn
xx.40 Manchester Piccadilly
Milton Keynes Central, Crewe, Wilmslow, Stockport
xx.43 Birmingham New Street
Milton Keynes Central, Coventry, Birmingham Internation
xx.46 Crewe
xx.57 Lancaster
Crewe, Warrington Bank Quay, Wigan North Western, Preston
This includes XC taking back BHM-GLC/EDB, and 1 of the 2tph XC Brum - Piccadilly transferring to VT. If they had enough 390s, there is still an xx.00 path for a non-stop to Stoke.
I have roughly checked it and I *think* they should all be out of each others way. My only problem is the 07 and 10, so I think the easiest solution would be
xx.07 Chester
MKC, TAM, CRE
xx.10 Liverpool
Watford, NUN,CRE,RUN
or swap the fast and the slow(er)
