This was the second batch of standard SR shunters based on the English Electric 6KT 350 hp (260 kW) diesel engine. They were built at the BR Ashford Works over the period 1949-1952. They were numbered 15211-15236 and became Class 12.

The engine is an English Electric 6-cyl, 4-stroke, 6KT and the traction motors are 2 x EE506 axle-hung, nose-suspended, force-ventilated traction motors with 17.5:1 double reduction gear drive. The Main Generator is an EE type EE801/7D, flange-mounted single bearing rated at 490 kW.

British Rail Class 44 - Wikipedia, the free encyclopedia (557 words)
	The British Rail Class 44 or Sulzer Type 4 diesel locomotives were built by British Railways' Derby Works between 1959 to 1960.
	In part inspired by LMS prototypes 10000 and 10001 the Class 44 diesels were some of the first big diesels commissioned for the British Rail modernisation project and were the precursors to the Class 45 and Class 46 locomotives modelled on this design.
	Once the Class 45 units were available with their higher running speed the steam heating boilers were removed and the Class 44 locomotives were assigned to freight duties, largely in the East Midlands where they were all based at Toton.
