Development 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. After considering enlarging the existing depot at
Bricklayers Arms, it was concluded that the growth in freight traffic necessitated a new depot. Land was purchased on
Crayford marshes, with plans for a brick-built 10-road shed of in length, with two of these feeding a repair shed located in the north eastern corner. With a budget of £55,000, construction started in April 1898, with an allowance for building 145 railway workers houses. On 1 May 1895 a
triangular junction was opened with the
Bexleyheath line. The shed, initially called
Whitehall, Erith was completed on 27 October 1899, under the
South Eastern & Chatham Railway (SE&CR). Better equipped than major depots at
Stewarts Lane or
Ashford, But its opening allowed closure of the smaller sheds at
Woolwich Arsenal and
Deptford. and by 1910 the full "railway village" of houses and ancillary community buildings had been completed.
Southern Railway After grouping in 1923, the
Southern Railway (SR) began the
electrification of the former SE&CR suburban lines, but using the
London and South Western Railway 660 V
third-rail system. It was planned that the line to Dartford would be an early conversion, so the new trains required servicing. In 1924 the SR proposed reconstruction of Slade Green into a dedicated electric maintenance and repair unit. A budget of £30,000 was allocated to convert the existing shed, added to by an adjoining heavy maintenance shed facing Dartford, capable of all repairs and maintenance. 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. In 1935, along with
Orpington, the site became home to the first mechanical carriage washer in the UK.
British Rail Southern Region With the introduction in 1952 of the
BR Class 415 4EPB units, under the
Southern Region of British Railways, in June 1954 the shed was extended by at its London end to fully accommodate a complete 10-carriage unit. The bricks purposefully replicated the original 1899 building, while the new roof had a hump to allow for better rain water removal. On completion, on 1 August 1953, the depot and adjacent
railway station officially became
Slade Green.
1990/1: Networker depot rebuild With the introduction of the
Class 465 Networker and
Class 466 Networker fleet, it was proposed in 1990 by
British Railways to demolish the 1925 shed and build a brand new eight road structure. Allocated a budget of £20million, the new maintenance depot was officially opened on 8 April 1991, with original BR green 4EPB No. 5001 and a cab mock-up of No. 465001. 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. ==Present==
