Evening of Monday 1st December has to be one of their most dire periods ever: two hours waiting on the Piccadilly station concourse for a series of train services that were, sequentially,

after points failures at Ashburys.
Says it all when the rail-replacement buses that turned up were all booked out to Transpennine Express, not Northern Rail.
