My wife only travels by train about once a year, usually on quite lengthy journeys though. Last Tuesday was the return day of her first, and probably only, trip this year. Gatwick to Reading was fine, but the connection at Reading for Penzance was half an hour late leaving due to the evacuation (I've chosen the word carefully!) of Coach B 'owing to a blocked lavatory discharging into the carriage, requiring specialist cleaning services'. The Train Manager was, of course, quite exercised with all this, to the extent that her ticket was not examined during the course of the journey or, needless to say, at Penzance. My point is this- what if that train had not had another member of staff on board other than the driver? Would it have left Reading with that blocked lav? If so, it's completely unacceptable.
