I can recall that when Greater Anglia transferred the class 315 stock to Tfl in the middle of a timetable. There were three early morning Southend Victoria services operated by class 321's with 1st class accomodation, although the timetable did not have the 1 symbol. There was a poster who was challenged by an Inspector and showed a copy of the timetable to prove that he was in the right. When Greater Anglia had short forms last year they declassified 1st class. They kept it quiet and I found out about it and claimed £50 back.
