As the Deltics were then in production, it was decided to produce the locomotive on the same production line; the bodyshell used for DP2 reputedly being the eighteenth made. While DP2 looked like a [[British Rail Class 55|Class 55]] locomotive in outline, there were many detail differences; particularly the large bodyside [[radiator]] vents at one end, and the single roof fan as opposed to the four symmetrically placed fans on the Deltics.
