Hudson Hunslet RNAD Broughton Moor Shunters

Royal Naval Armaments Depot (RNAD) Broughton Moor in Cumbria had an extensive railway network, including an internal system in 762mm gauge. These four shunters were amongst those operated at the depot and were built in 1939.

Information
Number built:	4
Built:	1939
Builder:	Hunslet for Robert Hudson
Motor:	Ailsa Craig CF2 diesel
Power:	50 hp (37 kW)
Wheel arrangement:	0-4-0DM

The diesel shunters had diesel mechanical transmission and were flameproof (obviously due to the presence of explosives and combustible materials!) The railway system was closed down in 1932 and the remaining railway stock (standard and narrow gauge sold off).

Robert Hudson Fordson "Go-Go Tractors"

The Fordson tractor was a mass produced tractor built by the Ford Motor Company from 1917 onwards, Robert Hudson adapted the engine, gearbox and drivetrain to create a locomotive that could run off petrol, diesel and other fuels. The "Go-Go Tractor", as it was referred to, was produced from the 1920s onwards. The Ford engine was connected to the tractor axle via a roller chain. The resulting locomotive was simple, one major drawback was that as it utilised the original tractor gearbox it had three gears in one direction and only one in the other, not so much a problem for an agricultural tractor but a limitation for a bi-direction locomotive.

Hudson Hunslet 4wDM Shunters

Robert Hudson began producing narrow gauge locomotives for industrial use in 1911, at first steam locomotives in partnership with Hudswell Clarke. Later locomotives with internal combustion engines were built, these in partnership with the likes of Kerr Stuart. From 1937 Hudson went into partnership with the Hunslet Engine Company and the locomotives began to carry a Hudson Hunslet badge. These were simple locomotives usually powered by a 20 hp/15 kW) Alisa Craig diesel with chain drive.

Builder:	Robert Hudson / Hunslet Engine Company
Motor:	Alisa Craig CF2 diesel
Power:	20 hp (15 kW)
Wheel arrangement:	4wDM

The locomotives were simple in design without any enclosed cabs though there were options to add these if the customer required. Later versions, built in the 1950s, had more powerful engines, up to 50 hp (37 kW) and were slightly more refined in design though largely unchanged. A number of these shunters have been preserved both in the UK and abroad.
