French transport group Keolis has been awarded a new franchise to operate London's Dockland's Light Railway (DLR).
Keolis, a subsidiary of SNCF, will operate the franchise from December 2014 to April 2021, with an option to extend it until 2023.
Serco, which has held the franchise since 1997, said it was "disappointed" not to have been selected to continue operating the rail line.
Keolis also operates the Southeastern, Southern and London Midland rail franchises through its Govia joint venture with Go-Ahead Group. In May, it won a seven-year franchise to run the newly extended Thameslink rail network.
In 2018, Crossrail services between central London and Shenfield in Essex and and Abbey Wood in south east London will begin to interchange with the DLR at several stations including Canary Wharf, West India Quay, Stratford and Custom House.
