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.

<span class="mw-page-title-main">OO gauge</span> Model railroad gauge

OO gauge or OO scale is the most popular standard gauge model railway standard in the United Kingdom, outside of which it is virtually unknown. OO gauge is one of several 4 mm-scale standards, and the only one to be marketed by major manufacturers. The OO track gauge of 16.5 mm corresponds to prototypical gauge of 4 ft 1+12 in, rather than 4 ft 8+12 in standard gauge. However, since the 1960s, other gauges in the same scale have arisen—18.2 mm (EM) and 18.83 mm (Scalefour)—to reflect the desire of some modellers for greater scale accuracy.

Under the Whyte notation for the classification of steam locomotives, 0-4-0 represents one of the simplest possible types, that with two axles and four coupled wheels, all of which are driven. The wheels on the earliest four-coupled locomotives were connected by a single gear wheel, but from 1825 the wheels were usually connected with coupling rods to form a single driven set.

TT scale is a model railroading scale at 1:120 scale with a track gauge of 12 mm between the rails. It is placed between HO scale (1:87) and N scale (1:160). Its original purpose, as the name suggests, was to make a train set small enough to assemble and operate on a tabletop.

Hornby Hobbies Limited is a British-owned scale model manufacturing company which has been focused on model railways. Its roots date back to 1901 in Liverpool, when founder Frank Hornby received a patent for his Meccano construction toy. The first clockwork train was produced in 1920. In 1938, Hornby launched its first OO gauge train. In 1964, Hornby and Meccano were bought by their competitor, Tri-ang Railways, and sold when Tri-ang went into receivership. Hornby Railways became independent again in the 1980s, and became listed on the London Stock Exchange, but due to financial troubles reported in June 2017, became majority owned by British turnaround specialist Phoenix Asset Management.

The Yorkshire Engine Company Janus is a line of 0-6-0 wheel arrangement, diesel–electric locomotives that weighed 48 long tons and had a maximum speed of 23 mph (37 km/h). The two Rolls-Royce C6SFL diesel engines gave a total power output of 400 hp (300 kW). Each engine had its cooling system at the outer end, and its generator at the inner end. There were two traction motors, each being powered by one generator, thus simplifying the electrical system.
