九廣鐵路
The East Rail line () is one of ten rapid transit lines of the Mass Transit Railway (MTR) system in Hong Kong. It used to be one of the three lines of the Kowloon–Canton Railway (KCR) network. It was known as the KCR British Section () from 1910 to 1996, and the KCR East Rail () from 1996 to 2007. The East Rail was the only railway line of the Kowloon-Canton Railway Corporation (KCRC) before the construction of "KCR West Rail" (now known as Tuen Ma line).
