Kearsley / Heysham Electric Locomotives

It is an interesting, though these days often forgotten fact, that industrial railways were among the pioneers of electric traction in the UK, with some industrial electric locomotives predating those designed for the main line networks [1]. Coal mines and power stations were the most typical users of these early electric locomotives including at Kearsley Power Station which had this fleet of four 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].

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