As I have commented before, when a train is early or on time, this results in 2 things happening:
1) Lots of people miss the train as they usually expect it to be late.
2) The FGW staff do a little may-pole style dance of celebration. Which then makes the train late.
Collyn the train manager was very keen to tell us that we'd have to wait at Oxford for a bit and that there was nothing wrong with the train or the track and that we were just early... How cynical does he think we are.....
