Brockley railway station is on the main railway line between London Bridge and Brighton.
The station is operated by London Overground, with London Overground and Southern trains serving the station. Thameslink and some Southern services pass through the station. It is in Travelcard Zone 2.
The line was part of the London and Croydon Railway which opened in 1839. The station was opened on 6 March 1871, although today's buildings are of a modern design: the platforms are only located on the outer, Slow lines, since the station is only served by London Overground trains between Highbury and Islington and West Croydon or Crystal Palace, local trains between London Bridge and Caterham and by the London Bridge to London Victoria loop line via Crystal Palace, plus some London Bridge to Guildford and Dorking in peak times.
At the London end the line is crossed by the Nunhead to Lewisham line. At this location adjacent to Brockley station was sited Brockley Lane station which closed in 1917 with the original London, Chatham and Dover Railway branch to Greenwich. The connection of that line to Lewisham is a later development. The possibility of opening platforms on this line with direct access to Victoria Station and the Bexleyheath Line to Dartford has often been suggested but is currently low on TfL's priorities.
Crofton Park, on the Blackfriars to Sevenoaks line, and which also runs from Nunhead, is a mile to the south. Neither of these other lines has a physical connection with Brockley station, despite the trains running over the station. The next station to the north is New Cross Gate, and the next station to the south is Honor Oak Park.
Brockley forms part of the new southbound extension of the East London Line that opened on 23 May 2010 and forms part of the London Overground network. Ticket barriers were installed at this time.
Brockley is served by 8 trains in each direction off peak, with additional Southern services at peak hours. Southern operates 4-8 car trains throughout the day, with 10 carriage trains at peak hours.
London Buses routes 171, 172 and 484 and night route N171 serve the station.
