I ask because of this remarkable co-incidence reported on Northern's website. Today's 1644 Hadfield to Manchester Piccadilly is cancelled "... due to a fault on a train in front of this one." Last updated 16:02:41 26/03/2020 16:44 Hadfield to Manchester Piccadilly due 17:23 will be cancelled. This is due to a fault on a train in front of this one. Fair enough, except that the same page also advises that the 1603 Manchester Piccadilly to Hadfield is cancelled "... due to passengers causing a disturbance earlier in this train's journey." Last updated 16:01:22 26/03/2020 16:03 Manchester Piccadilly to Hadfield due 16:41 will be cancelled. This is due to passengers causing a disturbance earlier in this train's journey. As far as I know, the 1603 ex Piccadilly forms the 1644 back from Hadfield, so is the truth of the matter that passengers caused a disturbance (on an earlier working of the train that should perform this return working) because their train was delayed due to a fault on another train?
