This was the second batch of standard [[Southern Railway (Great Britain)|Southern Railway]] shunters based on the [[English Electric]] 6KT 35 hp (260kW) diesel engine. These locomotives (BR numbers 15201-15203) were built by the SR in 1937 and were later classified [[British Rail Class D3/12|D3/12]]. The Class 12 locomotives were built at the [[Ashford railway works|BR Ashford Works]] over the period 1949–1952. They were numbered 15211–15236 and became Class 12. No locomotives survived long enough to acquire Class 12 [[TOPS]] numbers though. {{British Rail Locomotives}} {{Transport-stub}} [[Category:British Rail diesel locomotives|
