And weekend trains to Birmingham at Virgin's weekday prices that

longer than Chiltern.

Not the best time to have posted that, really! The other weekend
the resignalling of the South Midlands and the repositioning of the
junctions at Tyseley (to allow higher speeds for non-stop services)
commenced. As a result, weekend Chiltern services are only running
(alternately) to Dorridge and to Coventry, hourly, on Saturdays and
to Dorridge and to Birmingham New Street (via Coventry) on Sundays
until the end of the autumn.

They don't get as far as Dorridge on the Sundays. The NRT shows
alternate trains (the ones not running to Birmingham New Street) as
terminating at Leamington, but in fact they run on to Warwick
Parkway, where up trains start back from the down platform, crossing
back at Warwick.
