Not a cancellation as such - more an illustration of the crumbling edge of quality, however last year I posted the thread below about an incident when the main line to Wakefield Westgate was closed due to engineering works, resulting in the last Hallam line train being grosely overcrowded and heavily delayed (eventually an additional unit was summonned).
Was aiming to get my usual train back to Normy this evening. Arrived in Leeds to find the train full and standing, to the extent that no one could physically get on. When I enquired as to why this situation ensued, I was told it was because the Wakefield Westgate line was closed and people...

Fast forward to yesterday, and the mainline was again closed. Surprise Surprise (It's not Cilla'ere) exactly the same situation with several carriages worth of Wakefield passengers trying to pile on to the last Hallam train. The train was again over twenty minutes late leaving as they tried to squeeze everyone onto two carriages. When it did eventually leave, it was I would say dangerously overcrowded - not having much to hold onto I lost my footing at one point, and almost ended up accidentally elbowing one poor gent in the face (fortunately he moved out the way).
Wouldn't you have thought they'd have learned from last year !
