L402 (51335, 59487 & 51377) comes off the double track section of the Cotswold Line at Ascott-under-Wychwood on 17 June 1980 with the 5A09 19:15 (in theory!) Moreton-in-Marsh to Oxford ECS. This was running almost an hour early, which meant that rather than waiting at Moreton for the booked 58 minutes, after arriving with the 2B48 15:29 Paddington to Moreton-in-Marsh, it must have left straight away! Also, note that the guard appears to be standing up in the cab and displaying a red flag to the signalman. I've no idea this many years later what that was about.
