37893 waits in the down loop at Pilning on 16 March 1993 with the 6V25 08:42 Grain to Llandarcy bitumen empties. On the extreme left of the picture is my Volkswagen Jetta garage courtesy car, with the footbridge of Pilning station just visible (at least on the original) directly above it. I couldn't resist taking a second shot of this train, from further back towards the Severn Tunnel, when eventually it departed the loop.
