This is a list of the stations of the MTR, the metro system in Hong Kong, sorted according to their service lines. After the merger with the Kowloon–Canton Railway on 2 December 2007, the operation of the East Rail Line, West Rail Line, Ma On Shan Line and the Light Rail system was transferred to the MTR Corporation. The addition of the three lines expands the metro system to encompass 10 heavy rail lines and 87 stations. Serving exclusively in northwestern New Territories, the light rail network comprises 12 routes, serving 68 stops. The network is being expanded and several new lines are being proposed or under construction.
