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.

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.
