Docklands Light Railway

It opened on 31 August 1987 and, after extensions, reaches north to Stratford, south to Lewisham, west to Tower Gateway and Bank in the City of London financial district, and east to Beckton, London City Airport and Woolwich. DLR track and trains are not compatible with those of London Underground (although the track gauge is the same), but the two systems share a ticketing system, have several interchange stations, and the DLR is shown on the London Underground Tube map.
