A proposal to create a new Brockley Interchange, linking the existing station to the Nunhead to Lewisham line with new platforms at the former Brockley Lane station, is included in the London Borough of Lewisham's 2019–2041 transport strategy.

The document gives an approximate date of 2030 and states that funding from TfL and Network Rail would be needed for the project.

Crofton Park, on the Blackfriars to Sevenoaks line, and which also runs from Nunhead, is a mile to the south.

Brockley forms part of the new southbound extension of the East London line (now the Windrush line) that opened on 23 May 2010 and forms part of the London Overground network.

Brockley is on the Windrush line of the London Overground, with services operated using Class 378 EMUs.
