Greg,
I was on my way home, so it just turned a 25 hour journey into 27 hours.
What wasn't good was that there were no station staff on duty, and we had been given scant information when turfed off at Hexham, just told a bus would turn up "soon". So I had had to emerge from my shell and co-ordinate a difficult situation- to use live train tracking to know where the incident was (at Low Row). So when the bus turned up eventually to take us to Haltwhistle I had to tell the driver to contact Manchester control for authority to extend to Carlisle, otherwise I'd have been another 2 hours late.
In the meantime 2 other trains had turned up to terminate- on each of those times I had got the guard to phone control to track the bus, so as to keep the crowd reasonably happy. I have seen such situations spiral downwards fast without staff or information.
Everyone was pretty satisfied at the end of the day, which was a result.
I would have to say that the bus provided was ancient- it is years since I have seen a UK bus with ash trays!
