Hither Green marshalling yard, is a large railway marshalling yard designed for the concentration of freight traffic to and from South East London, and for transfer to other yards in London. It is situated on the north side of the South Eastern Main Line between Hither Green and Grove Park stations. The facility was conceived and built by the South Eastern Railway after 1895, but by the time it opened in 1899 this railway had become part of the South Eastern and Chatham Railway.
