Crossharbour is a DLR station west of Cubitt Town on the Isle of Dogs in east London. It is between Mudchute and South Quay stations and is in Travelcard Zone 2. The Docklands Light Railway station opened as "Crossharbour" on 31 August 1987, and was renamed in 1994 to "Crossharbour and London Arena". Now that the neighbouring London Arena has been demolished the original name has been reinstated.
There is a reversing siding between the two running tracks just to the south of the station, and some trains (mainly from Stratford DLR station) used to terminate here as Lewisham DLR station was unable to handle too many trains. Nowadays however, it is rare to see trains terminate at Crossharbour, as many trains from Stratford now terminate at Canary Wharf DLR station. The St John's Estate is social housing estate adjacent to the DLR station.
