Railway station in Travelcard Zone 4 opened 1864. Also served by the Croydon Tramlink. The Wikipedia page is [1].
The railway through Elmers End was opened by the South Eastern Railway on 1 April 1864 as an extension of the Mid-Kent Line from New Beckenham to Addiscombe; there was a branch, opened on 29 May 1882 to Hayes at this station. The portion of the line to Addiscombe, which was originally named Croydon (Addiscombe Road), was closed in 1997 when Tramlink took over much of the trackbed from Elmers End. One former railway platform is now the terminus for Tramlink route 1 services to central Croydon.
