British Rail Class ES1 was a class of two electric locomotives commissioned by the North Eastern Railway in 1905. They were of steeplecab design.

Both locomotives passed to the London and North Eastern Railway in 1923 and to British Railways in 1948. This was a class of electrically powered locomotives in the pre-TOPS period.

Usage

These locomotives worked the one mile freight branch from Trafalgar Yard to Quayside Yard on Tyneside. This included a 1 in 27 gradient and a single line tunnel on a sharp curve which made it difficult to work with steam locomotives. Current was collected from a third rail in the tunnel and from overhead wires in the yards. The electric locomotives were replaced by diesel shunters when operations changed from electric to diesel on February 29th 1964 but number 26500 is preserved at the National Railway Museum, York.
