[2] The late-Victorian era hamlet of Slade Green consisted of two small farming communities until the South Eastern Railway's (SER) development of the North Kent Line from Strood and Dartford to London Bridge.

[3] The shed, initially called Whitehall, Erith was completed on 27 October 1899, under the South Eastern & Chatham Railway (SE&CR).

Work started immediately, including conversion of the roof to a flat form, and were completed by the end of 1925, with electric services to Dartford commencing on 6 June 1926.

[3] The bricks purposefully replicated the original 1899 building, while the new roof had a hump to allow for better rain water removal.

The new building still had the facilities to carry out heavy repairs on the 1952 slam-door 4EPB stock, a function it fulfilled until the final 4EPB withdrawals in March 1995.

[3] Today the site is owned by Network Rail and operated by Southeastern, providing berthing for a range of different EMUs.
