20309 & 20311 Spetchley 30 April 1999

20309 & 20311 sit in the loop at Spetchley on 30 April 1999 with the late running 7M53 13:58 Bridgwater to Sellafield nuclear flask. Some unexplained problem caused the train to remain in the loop for 40 minutes, resulting in the delay increasing to over two hours by the time it finally left.
