LMS 10001 approaches Wembley Central with a Euston to Bletchley train on 7th May 1955.

Peter Kerslake says "Diesels 10000 and 10001 were used on crew training duties at about the time of this photograph working from Camden and running between Euston and Bletchley before they returned to more demanding roles on the West Coast Main Line Top Link services throughout 1956 and 1957.
Both Diesels had spent the previous two years on the Southern Region, allocated to Nine Elms M.P.D. respectively from March and April of 1953, but their time on the Southern was marred by numerous failures."
