They resumed an almost pre-Covid service on the 14th September IIRC. If this is down to Covid cost cutting then it is quite worrying - There is a reason why both of these services have been half-hourly since 1995 (At least I think that’s the date).
What’s even worse is that the 15:16 & 16:16 Bradford to Ilkley, as well as the 15:51 Ilkley to Bradford trains are missing, both of which saw custom from at least 100 Schoolchildren each, maybe 200 on some, although at least the 07:48 Ilkley to Bradford is still in the schedule, another service well used by Schoolchildren. Completely idiotic.
