And Virgin operate many limited stop trains into Euston in the rush hour (e.g. one Wolverhampton - Euston train which runs non stop after Birmingham New Street!)
This is all done to speed up journey times for commuters and business travellers
As I said before about Manchester, and which you blithely ignored, presumably because it doesn't fit with your world view, running times from Birmingham New Street to London in the peak, all the way from 5.50am to 8.50am, are remarkably similar, 1hr 22, 1hr 25, 1hr 27, 1hr 24.... check on a journey planner if you don't believe me.
Yes, the 7.30 from New Street does it in 1hr 12, but frankly, in a sequence of Pendolinos every 20 minutes, over a three-hour period and then the same ever onwards off-peak, that one train is neither here nor there. They don't even bother with a single train doing a quick run in the return direction in the late afternoon and early evening.
I'm sure saying 'London in 72 minutes' looks fine and dandy in mailing shots to Birmingham businesses, but that's about all the value it has. It's just the 2009 equivalent of the couple of
BR▸ trains that did the run in 92 minutes in the 1980s and gave rise to the huge sign on the postal depot at Curzon Street - 102 minutes was more like it the rest of the time.
A rather more accurate comparison for the Chiltern service pattern south of Banbury would be Oxford, where both fast and slow London trains start and beyond which Cotswold Line peak trains make just one stop at Reading. Equally on the
WCML▸ , there are several
LM▸ -run fasts starting at Northampton and Milton Keynes.
For goodness' sake, please tell me you aren't seriously trying to equate the volume of traffic generated for Virgin and Chiltern by the population of the West Midlands metropolitan area and Coventry, Leamington and Warwick, with that available from Hereford and Worcester?
If you don't think a sequence of Worcester-London and return trains every 30 minutes in the peak - with pretty consistent timings of say 2hr 5min-2hr 10min - would be attractive to the expense account classes of Worcester with their ^129 first class returns, could you please explain why - instead of coming up with yet more chalk and cheese comparisons.
