Background
1.1.1 The Railway Development Strategy 2014 (RDS-2014) announced by the

1.1.2 This new railway system has been included in the approved Schedule 3
Environmental Impact Assessment (EIA) for Tung Chung New Town Extension
(TCNTE), which has included the new stations at TCE area and TCW area and the

this railway system is conducted to address the associated environmental
impacts, taking into account of the latest design.

on 12 July 2022 (Register No. AEIAR-235/2022). The Environmental Permit (EP)
No. EP-614/2022 was then issued on 9 August 2022.
