what is it?

British Rail Class D2/12 was a class of ten locomotives commissioned by British Railways in England. They were diesel powered locomotives 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.
