Kearsley/Heysham Electric Locomotives

It is an interesting, though these days often forgotten fact, that industrial users were among the pioneers of electric traction in the UK with some industrial electric locomotives predating those designed for the national network [1]. Coal mines and power stations were the most typical users of these early electric locomotives including Kearsley Power Station which had this fleet of 4 electric locomotives built over an extended period as dictated by demand. The Kearsley locomotives operated off 500v DC overhead supply [2] and were owned by the Lancashire Electric Power Company [3].

Information
Number built: 4
Built: 1928, 1936, 1944, 1946
Builder: Hawthorn & Leslie / Robert Stevenson & Leslie
Engine: 4 BTH traction motors (500v DC OHLE / battery)
Power: (First 2) 180 hp (134 kW)
(Last 2) 260 hp (193 kW)

Following the closure of Kearsley Power Station in 1982 2 locomotives were converted to battery operation [4] (with the pantograph removed and batteries fitted in the cab) and worked at Heysham Nuclear Power Station until 2009. Three of the 4 (locomotives 1 to 3 in fact) locomotives have been preserved.
