31407 arrives at Oxford station on 21 October 1988 with the very late running 1E35 12:03 Poole to Newcastle 'Northumbrian' service. Obviously a Class 31 was not the usual traction for this train, and I was very surprised to see it coming, which explains the not very imaginative end of platform picture. 47638 had failed shortly after leaving Poole, and the train was rescued by 73133 & 73139, which would have made an even more interesting picture. The reversal at Reading was the opportunity to replace the electro diesels with some slightly more powerful traction.
