Bachmann OO 32-441 BR D5149 Class 24/1 with Headcode Boxes Green Small Yellow Panels

When British Railways decided on a 4-character headcode system the diesel locomotive designs being built needed to be revised to accomodate the 4-character display instead of the steam-era disc headcode array. The Derby type 2 design, later class 24, was equiped with a headcode box fitted into the roof end dome of the cab roof. The design revision included other internal equipment changes, creating the first sub-class of 24/1. This style of cab end was continued when the more powerful engine was fitted, creating class 25, but later revised with side fairings over roof-mounted air horns for the 25/1 and subsequent 25s.
This version of the 24 has not been produced previously and provides a further visual variant of the popular and useful Derby type 2.
