There seems to be a lack of symmetry.
The Liverpool to Euston uses the slow after Milton Keynes, but the Euston to Liverpool uses the fast to Milton Keynes.
So there are 16 direct trains from Crewe to Hemel, but only 2 from Hemel to Crewe.
Is this covered by the splitting/joining at New Street?
If so I hope the published timetables do a better job than Realtime Trains (I accept this is not its intended use).
How many of these combined routes will be advertised as through journeys, and how they will be announced on the trains?
I noticed that but with the Rugeley (via Walsall) services in reverse.
It seems very odd to have this asymmetry if you are going to advertise this as a through service; I'd have said either have an easy to understand, clean symmetric service where a through journey from A to B can always be made from B to A, or alternatively, run the trains to the same diagrams for operational convenience but don't advertise them as through services.
Actually while we're on the subject of the southern WCML what's the reason for the _three_ LNWR services from Euston to New St? The xx49 and xx13 are the ones which make sense as they're relatively fast but what's the rationale for the other one (xx24 or xx54, forget which) which is fairly slow anyway?
I'm not a local (though I am an occasional user of VT Pendolino services on the WCML, most recently this weekend) but was wondering hypothetically how a more regular, even interval, consistent-stopping-pattern service on the London Birmingham corridor (at the expense of the VT services dropping to 2tph off peak) would work. Something like this:
Two per hour VT trains: Watford (1tph), Milton Keynes (1tph), Coventry, International, New St (one continuing to Wolverhampton and northwards as now);
Two per hour 'fast' LM services: Watford, Milton Keynes, Northampton, Rugby, Coventry, International, New St (catering for the principal intermediate stops and providing an alternative from London to New St which is still reasonably fast). These then continuing to Liverpool;
Two per hour semi-fast services (similar to the current xx24 and xx54 but one per hour going to Northampton and one to Rugby);
Two per hour slows (the Tring terminators but extended to Milton Keynes);
Two per hour Coventry-New St all-stations shuttles, perhaps then continuing to Wolverhampton as the stoppers.
