The British Rail uniform dates this picture just as much as the DMU! C317 (53911, 59446 & 53858) has just arrived at Gloucester station on 12 November 1983 with the 2B27 09:32 Worcester Foregate Street to Swindon service. As this required a reversal at Gloucester, the driver had to change ends, and is pictured here just opening the door to the rear (soon to be leading) cab.
