47103 heads west past South Marston on the evening of 16 June 1984 with four Mk1 coaches. I've no idea what this working is, as it doesn't seem to match up with anything in the working timetable. Presumably it is a special ECS, but to where? The only clue is that allegedly earlier in the day the loco had worked the 1A52 10:45 Paignton to Paddington service.
