Sorry to hijack the thread, but does anybody know any detail about what happened with the down Night Riviera on the 12th?
I was on it, in coach H at the back of the train. At some point during the journey a loud hissing noise began at the connection between G and H and we stopped for a while outside what I believe was Exeter (I could see an SWT 159 from my window) while this was rectified (only partially, it was still hissing, just more quietly). We arrived in Penzance some 30 minutes late after a much shorter than timetabled stop at Plymouth, but my friend who was also on the train says that we were already about 40 minutes late passing Westbury, so what was the cause of the delay?
