Could it be running onto a Street Shuttle? Can't remember times off hand, but pretty sure they run 'past' the hour.
If it was running onto an M2, then it wouldn't need to turn around anywhere...
28b - ....Ouston - Station Lane,
M2 - Station Lane, Fell Bank, Portmeads, Portobello Road etc - Washington
M2 - Washington - Portobello Road, Portmeads, Fell Bank - Station Lane.
28b - Station Lane, Ouston etc
Just trying to think of another option, because after ignoring The Bronx for donkeys years, why would they decide to serve it on a night?
