Plus add the standby sets that are at various places en route, the Leeds and Yorkshire, Lincoln, Inverness / Aberdeen, Glasgow, Newcastle and London KX.
Probably missed a few just of the top of my head. I believe there is around 4 standby and of course the few that are at Bounds Green/Craigentinny at the moment.
