British Rail Class D2/7 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 three-speed Power-flow SSS ( synchro-self-shifting) gearbox, [1] was a Hudswell Clarke speciality.

Preservation

One locomotive was originally preserved after withdrawal but was then scrapped in C F Booths, Rotherham in 2005.One locomotive does survive at the National Coal Mining museum at Wakefield. The locomotive is named ‘Manton’ after its working life at Manton colliery in Nottingham.


Modelling

A kit is available from Invertrain [2] in 7 mm Scale ( O Gauge)

Mercian Models [3] make kits for this locomotive and the very similar industrial version, in both 4 mm and 7 mm scale.
