Tung Chung Line Extension is one of the railway schemes proposed in the Railway Development Strategy 2014. The project is composed of “Tung Chung Line Extension (TUE) – Tung Chung West Station and Tunnels Project” (Contract No.: 1201). It’s a 1.3km westward extension from the existing railway tunnel of Tung Chung Station and the new Tung Chung West Station near Yat Tung Estate.

The project involves a westward extension of the Tung Chung Line (TCL), and the design and construction of a new station at Tung Chung West and a tunnel from the existing Tung Chung Station. When completed, the project will improve railway accessibility to Tung Chung West and Tung Chung East areas, as well as the proposed developments at Lantau North and the airport expansion plans.

The Tung Chung West Station and Tunnels project will serve existing public housing estates and property developments in the vicinity. The construction of the TUE is expected to begin in mid-2023, with a target completion date of 2029.
