English Electric Type 4s were regular visitors to Derby in the 1960 and 1961 for both Heavy and Light repairs, although they did not work the Midland Division trains. Two of them are in this picture taken on 22nd May 1961, No.D223 which had been named Lancastria on 19th May had been in the Works since 13th March. It was to return twice more within the next few months, from 29th May to 1st July and again between 18th July and 9th September, which suggests Derby was having problems with it. The other locomotive is probably No.D214 which was to be named Antonia on 24th May and which had been at Derby since 19th April.
