C851 (51530, 59382 & 51462) passes Quedgeley on 6 May 1988 with the 2A21 09:30 Cheltenham Spa to Swindon service. There area a couple of interesting points to note about this picture. Firstly, the driver has forgotten to change the marker lights at Cheltenham, with the result that the unit is displaying two red lights on the front, against all the regulations. Presumably it was also displaying a white light to the rear. Secondly, the Dowmac concrete sleeper works sidings can be seen in the background, with the company's Ruston & Hornsby shunter plainly in view. The works closed shortly after this picture was taken, and the site has now been cleared.
