Docklands Light Railway

The Docklands Light Railway is a light rail service operating in the Docklands area of London. It first opened in 1987, having originally approved in 1984. It was part of a plan to enhance the out-of-use and delapidated Docklands.

Much of the route follows closed sections of 19th century railways. Much of the line lies on these old railway viaducts across the docklands, however some lies overground, some in tunnels (between Bank and Shadwell, and Mudchute and Greenwich. The trains are fully automatic and have two carriages.

The system has many interchanges - the most important of these is Poplar. All DLR routes pass through this station, with the station being situated near a triangular junction.
