In 1928 the Southern Heights Light Railway was approved, which would have left the Oxted line south east of the station and finished at Orpington.

[4] On it would have run a loop service from Charing Cross to Lewisham and then Woodside-Sanderstead-Orpington and back, or vice versa.

However, the scheme could not attract investment and was moribund even before electrification of the Woodside and South Croydon Joint Railway as its first stage.

[6] Electrification of the South Croydon-Selsdon and Sanderstead-East Grinstead sections of the Oxted Line was approved by BR in the early 1980s: South Croydon-Selsdon was electrified in 1984 using some redundant materials from the closed Woodside-Selsdon line, and a London Bridge to Sanderstead electric train service begun.

During the peak hours, there are also Thameslink operated services between East Grinstead, London Bridge and Bedford.
