From the
Chiltern application to run more London-Birmingham services thread
The Birmingham Moor Street departures at 09:45 and 10:15 on a weekday are the first and second for which super-off-peak tickets are valid as the restriction is arrival in London Marylebone after 11:30. Looking at
Realtime Trains for Friday 17 July 2025, when there were no planned timetable changes, 7 (4+3) car and 5 (3+2) car 168 formations ran. Looking at Friday 15th January 2027 both show
First & Standard class seating so potentially changed to Mk5 sets and hence reduced capacity, a potential issue on numerous posts in this thread. From experience albeit in summer not January both of these services can be 100% capacity if not standing from Leamington Spa then standing from Banbury onwards.
