DP2 diesel prototype Profile and Models

DP2, meaning Development Prototype number 2, was a prototype Type 4 mainline diesel locomotive. The locomotive was built by English Electric to demonstrate its wares to British Railways. As the Deltics were then in production, it was decided to produce the locomotive on the same production line. While DP2 looked like a Deltic in outline, there were many detail differences and internally was completely different with a single EE engine and generator, rather than twin-Napier engines in the Deltic. From 14 May 1962, BR tested it on regular London Midland Region services out of London Euston and later on the Eastern Region from London King's Cross. Following its first major overhaul in mid-1965 and clad in new two-tone green Deltic livery, it was used on the Sheffield Pullman workings until 1966. On 31 July 1967 it was involved in a serious accident at Thirsk, colliding at speed with the de-railed Cliffe (Kent) to Uddingston (Glasgow) cement train. DP2 sustained severe front and left hand side damage, and was taken to York shed where it remained sheeted over. The damage proved to be so great that it was considered uneconomical to repair.
