The railway from Orpington Sevenoaks was completed in 1868 under the directorship of the SECR (South East and Chatham Railway Co). After crossing the huge embankment over the Orpington Valley, it went into cutting before the 597 yard Chelsfield Tunnel which inspired The Railway Children by E Nesbit.  NIne navvies lost their lives building this. Much of the land belonged to Mr Waring of Chelsfield. Sidings were provided on the Up Line principally for coal, and on the Down Line there was a short siding on the level where the push-pull carriages were sometimes parked, and wagons for local farmers to both send and receive produce. In the late 1920s a footbridge across the Up Line sidings was built to serve the newly constructed Chelsfield Park Estate. A bomb fell on the tracks in 1940 demolishing the footbridge and damaging tracks. The original timber station was destoyed by fire (as was Knockholt) in the 1970s.  The skew road bridge carrying Warren Road has always been a popular location for photographers.
