A very rare working at Oxford, that was about to become even more unusual. Class 25s were very scarce visitors to Oxford by 1985, so the sight of 25042 working a Derby to Old Oak Common ECS was rare enough, but shortly after I took this picture of it passing Walton Well Road, on the approach to Oxford station, the ECS turned into a revenue earning train! Due to the failure of the 1A10 06:00 Hereford to Paddington service, some quick thinking railway employee commandeered the 25 which was conveniently heading in the right direction with a set of coaches, to form a substitute 08:20 Oxford to Reading relief train. A Class 25 on a twelve coach train is something you didn't see every day!
