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 [ [http://www.dmm-gallery.org.uk/colleng/4805-01.htm Durham Mining Museum - Colliery Engineering ] ] , 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.
