Docklands Light Railway (DLR) Line opened in 1987 (Tower Gateway-Poplar; Poplar-Stratford; Poplar-Island Gardens). This driverless metro system mostly runs on viaduct with limited underground and ground level segments; DLR serves East End and Docklands northern areas (which were - at DLR opening date - very residual and under utilized).
DLR system currently consists in 4 branches (Stratford-Lewisham; Bank-Lewisham; Bank-Woolwich Arsenal; Tower Gateway-Beckton) converging at Poplar.
The first phase (1987) was Island Gardens-Tower Gateway plus Stratford-Poplar, followed in 1991 by Bank extension (assuring a crucial connection to the underground/metro network), in 1994 by Beckton extension (1994), in 1999 by Lewisham extension (Island Gardens-Lewisham), in 2005 by the London City Airport and King George V extensions, in 2009 by King George V-Woolwich Arsenal extension. Another important addition (Canning Town-Stratford) was completed on August 2011, mostly running along a former North London Railway section.
