History of the South Island Line and West Island Line

The history of the South Island Line and West Island Line encompasses a number of proposals which were made for extending the Hong Kong MTR metro system to the south and west of Hong Kong Island, which were not serviced by any rail transport before 2014. The West Island Line opened as an extension of the Island Line on 28 December 2014. The South Island Line has completed construction and will commence service on 28 December 2016. The proposed South Island Line (West) is still in the planning phase and is expected to begin in 2021.

The West Island Island was first proposed in Railway Development Strategy 2000 by Transport Bureau,aiming to reform with Tseung Kwan O Line and part of the Island Line as a new railway corridor.

The MTR Corporation Limited (MTRC) submitted its first proposal for the South Island Line and West Island Line in May 2002. The new lines were intended to promote tourism in Aberdeen. The West Island line would be an extension of the Island Line.

In the proposal, the South Island Line would be a semicircular line with nine stations, intended to serve the southern end of Hong Kong Island towards Aberdeen. It would interchange with the Island Line at University and Wan Chai, which would also be its terminus stations. The stations in between would be, from University, Cyberport, Wah Fu, South Horizons, Lei Tung, Wong Chuk Hang, Ocean Park, and Happy Valley.
