On the road (railway!)

A mixed journey back to Oxford, with more buses and less trains than planned, partly due to an accident and partly to work on the railway near Crewe. Very, very busy too. I've never yet been on a train when they tell people standing up to get off and get the next train in 15 minutes, as this one is too full and won't leave the next station unless people get off. I was getting off anyway, as I had to change to a bus at that point, and had to fight my way through a crowd trying to get on, so I am not sure when the train headed off on its last leg to London.
