We recently received the engineering prototype samples of our Branchline OO scale models of the Class 24/1. We will be producing three highly detailed models which will include many features such as full directional and cab lighting, sprung buffers and a pre-fitted speaker to help ease the installation of digital sound. They will consist of:
- 32-440 – No. D5135 BR Green
- 32-441 – No. D5149 BR Green
- 32-442 – No. 24137 BR Blue

Originally designated as Type 2 (later to become Class 24 in the Total Operations Processing System [TOPs] system), a total of 151 of these diesel-electric locomotives following the 1955 modernisation plan. Powered by the 6LDA28-A Sulzer engine that gave an output of 1160bhp the vast majority of the locomotives were built at BR Derby, although some were constructed at Crewe and Darlington, with the first of the class, D5000 completed at Derby in July 1958. It was displayed to the general public during that month at Marylebone Station and although intended for use on the London Midland Region, they were sent to the Southern Region to deputise for Type 3 ‘Crompton’ diesel that were then running late for delivery.

By the time the entire Type 2 fleet was in traffic, they could be found operating on all regions with the exception of the Western. With a life span of 28 years these small, yet versatile, locomotives gave excellent service in all manner of roles in both branch and main line duties, either singularly or working in multiples. Removal from service of the Class began in the late 1960’s, with the final locomotive being withdrawn in 1981.
