The reason for it turns out to be TPE being daft. The service is crewed by a Northern driver and TPE guard, which makes sense, but appears to need a TPE driver on board for some reason. Due to them missing their pass working on a Northern service back to Leeds due to a late running TPE service (due to late Northern) they couldn't make the 1953. Now quite why they need a TPE driver on board I don't know, especially as it was permitted to run in passenger service without one, just omitting all the intermediate stops while remaining in it's booked path, Northern duplicate the route and stopping pattern as far as Heaton Lodge Jn, so I'd have thought Deighton might be thought to be the only station where a Northern driver would need a conductor, which if it didn't call there would be of little consequence due to the Wakefield - Huddersfield all stations being right behind it.
