Got the train from Edinburgh down to Sheffield for a home game on a Tuesday night against Coventry about five years ago I think. Left Edinburgh, sun streaming through the windows, but all change by the time we arrived at Doncaster and couldn't see anything for fog. As we got off the train, a guy was running past us to catch it, slipped on the icy platform and almost fell underneath the train! Wasn't a MASSIVE surprise when the game got called off shortly afterwards.
