British Rail Class D2/12 was a locomotive commissioned by British Rail in England. It was a diesel powered locomotive in the pre-TOPS period built by Hudswell Clarke with a Gardner engine. The mechanical transmission, using a scoop control fluid coupling and four-speed Power-flow SSS (synchro-self-shifting) gearbox, was a Hudswell Clarke speciality.
The D2/12 was mechanically similar to the earlier British Rail Class D2/7 but was of more modern appearance. The engine casing was lower, giving much better all-round visibility.
After British Rail
D2519 was employed at NCB Hatfield Main, Doncaster, South Yorkshire as a shunter. It was located there until at least 1984. D2511 is preserved at the Keighley and Worth Valley Railway.
