Docklands Light Railway
It carries more than 80 million passengers a year with consistently high levels of reliability and passenger satisfaction.
One of the first light rail systems in Britain, with one of the world's most advanced automatic train control systems, the DLR has expanded faster than any other UK railway.
Since opening in 1987 it has extended to Bank, Beckton, Lewisham, London City Airport, Woolwich Arsenal and Stratford International.
DLR Limited owns the railway's assets apart from the Lewisham extension. Part of Transport for London, its role is to oversee the operation of the railway and plan development that meets the needs of east and south-east London.
DLR Limited works with franchise operator Serco Docklands, a concessionaire responsible for building and maintaining the Lewisham extension and contractors for maintaining the Woolwich Arsenal, London City Airport and Stratford International network. Their aim is to deliver a safe, reliable and cost-effective service for east and south-east London residents, commuters and visitors.
