The 2C61 18:30 Oxford to Reading Network SouthEast service leaves Didcot station on 31 July 1992. This is a very odd working, as instead of the usual three car Class 117 DMU, this is in fact half of a Chiltern Line Class 115 four car unit with a Class 121 'bubble car' at the front! 51677 is nearest the camera, followed by a Class 115 trailer, and then Class 121 55024 (L124).
