On 2 December 2007 the Kowloon-Canton Railway Corporation (KCRC) granted a 50-year service concession (which may be extended) of the KCR network to MTRCL, in return for making annual payments to KCRC, thereby merging the railway operations of the two corporations under MTRCL's management. At the same time MTRCL changed its Chinese name from "地鐵有限公司" (Subway Limited Company) to "香港鐵路有限公司" (Hong Kong Railway Limited Company), but left its English name unchanged. After the merger, the MTR network included three more lines, East Rail Line, West Rail Line and Ma On Shan Line, as well as the Light Rail network and Guangdong Through Train to Guangzhou.
