Services at Nunhead are operated by Southeastern and Thameslink using Class 376, 465, 466 and 700 EMUs.

In addition, the service to London Blackfriars is extended to and from Welwyn Garden City via Finsbury Park.

Train services on the Crystal Palace High Level line ceased in 1917–1919 and 1944–1946 for wartime economies.

The Catford loop line opened on 1 July 1892, giving a second route out of London for the LCDR, and Nunhead became a three-way junction.

In 1925 the lines were electrified, and a new station at Nunhead was built on the London side of the original site.
