So Northern currently have a timetable on their website applicable from
5th April showing the 08:04 Stockport to Chester and 10:00 Chester to Manchester Oxford Road services. Despite that these services haven't operated since Maundy Thursday (1st April.)
There's been the following conversation on Twitter:
It's almost like Northern don't want anyone to use the train. The 10:00 Chester to Manchester via Altrincham service would be very useful today considering an incident has resulted in the suspension of services between Warrington Bank Quay and Manchester.
