Timetables will change from Sunday 13th December.
It’s a Covid timetable, reflecting the continuing reduction in passenger travel, and as such it shouldn’t be assumed that this is the service pattern over the long term.
The weekday timetable appears to be mostly similar (half-hourly in peak, hourly off-peak, timings similar but not identical to today). The main change is that the hourly evening service will be at different times and will continue to/from Hull. Effectively the local stopping service between Manchester and Huddersfield will be combined with the Manchester to Hull service in the evenings, which makes sense whilst passenger demand remains low.
On Sundays the local stopping service will be provided by the Manchester to Hull trains, still hourly but at different times.
