The engine in the photo which I took after being stopped at the crossing is call the Torquay Manor and I haven't noticed it before. The barrier to the crossing goes down well before the train arrives for safetyu reasons so there is plenty of time to stop the bus, switch the engine off and get out and up close to the track. The train then takes a minute or so to pass so getting stuck at both crossings can add 5 minutes to the journey time. Does take a good photo though.
