47575 has just passed through Cholsey station on 14 April 1984 with the 09:20 Manchester Piccadilly to Poole service, while Class 117 DMU L402 (51335, 59487, & 51377) pulls out of the station with the 12:35 Oxford to Paddington 'all stations' service. It should not have been possible to get both these trains in the same picture, as the 47 should by this time have been running round it's train at Reading prior to departing south for Basingstoke.
