It was powered by a [[Paxman (engines)|Paxman]] RPH Series 1 engine, capable of delivering 500&nbsp;[[Horsepower|bhp]] at 1,250&nbsp;rpm. It was driven via a Vulcan Sinclair fluid coupling to an SSS (Synchro-Self-Shifting) Powerflow gearbox. The gearbox provided three forward and reverse gears in either high or low range. It gave a top speed ranging from 5&nbsp;[[Miles per hour|mph]] (8&nbsp;[[Kilometre per hour|km/h]]) in 1st gear, low range up to 36&nbsp;mph (58&nbsp;km/h). It had an 0-6-0 wheel formation. {{British Rail Locomotives}} {{transport-stub}} [[Category:British Rail diesel locomotives|11001]] [[Category:C locomotives]] [[Category:Individual locomotives]]
