Probably the same way as they work their Sunderland diagrams, I’m quite confident the train crew diagrams and timetables were produced hand in hand!! Unless your onto something they’ve missed, who’d have thought you need to produce train crew diagrams to fit a timetable.
View attachment 71120 I suppose they look Impossible too? Even though they’ve been working those services for a decade.
nope no London depots at all. Lodging very much still exists for Sunderland crews and I’m sure that’s exactly how they will run the Blackpool’s.
