Lai King is an MTR rapid transit station located in Lai King, Kwai Tsing District, Hong Kong. The station is served by the Tsuen Wan Line and the Tung Chung Line, and provides cross-platform interchange between them. Both lines emerge from a tunnel to viaducts at the station.HistoryLai King was opened on 10 May 1982, originally as part of the Tsuen Wan Line. The station was designed to serve the large public housing complex located above the station, as well as the container terminal on the coast to the southwest of the station. When the Lantau Airport Railway was proposed, Lai King was chosen to be the interchange between the Tsuen Wan Line and the Tung Chung Line.During the construction of the Tung Chung Line platforms, the layout of the station was greatly altered. The northbound Tsuen Wan Line track was raised to a new level above the original station, providing cross-platform interchange with the northbound Tung Chung Line. Similar platform arrangements were constructed for southbound tracks. The original Tsuen Wan Line track was abandoned from the sidings south of the station to slightly north of it. A pair of tracks were also constructed for the Airport Express, which does not stop at this station.
