mornings. A few years later, the bow collectors originally fitted on their bonnets were removed and a pantograph installed on the roof instead. With few other changes, they remained in operation until the line was de-electrified and they were replaced with diesel locomotives on 29 February 1964. The line was closed five years later. Early photographs show the locomotives with "CLASS ELECTRIC 1" painted on the bufferbeams, but this does not appear in official records. In common with other LNER electric locomotives, no classification was given to these locomotives until 4 October 1945, when Nos. 1 and 2 were classified ES1 (Electric Shunting 1). No. 1 exchanged numbers with Class D3 steam locomotive No. 4075 on 30 September 1944, but after the steam locomotive was again renumbered (to no. 2000), the electric locomotive was able to resume its original number on 24 October 1944. On 14 June 1946, Nos. 1 and 2 were renumbered to 6480/1; and under British Railways, they became Nos. 26500/1 in April 1948. Preservation From 1968, ES1 (number 26500 under British Rail's number scheme) was transferred to Leicester Railway Museum. After that closed, in 1977 it was taken into the National Collection of the National Railway Museum, and is currently on display at Locomotion, Shildon.
