L D Bryant identifies the location, "6680 on up main line towards Cardiff, unusual choice of motive power for a main line stopper, although I would think the date is earlier than 1963, as the Barry branch trains (bay on left) had been worked by DMU's since c1960." Hovever it is carrying a 87D shedplate and it was only there from 09/03/1963 to the end of December 1963 when it went to Radyr.
