Ok, so a very specific query but it has me wondering and I'm sure someone here will have the answer!
Northern run and hourly stopping service between Stoke and Manchester Piccadilly. At Stoke it's always used Platform 3, a north facing bay platform, and is the only service to use that platform. Recently I've noticed that occasionally it instead arrives into platform 1, moves south into some kind of siding to wait, and then departs from platform 2, all while platform 3 sits unused. There's no work going on around platform 3 and sometimes it still uses platform 3 so the change seems odd, especially as it then gets in the way of the other services through the station.
Any ideas?
