Admiralty Station four-way interchange – planning through to preliminary design

Abstract

Admiralty Station (ADM) has been the busiest station on the Hong Kong rail network since the opening of the Island Line (ISL), with its cross-platform interchange to the Tsuen Wan Line (TWL). This two-way interchange station has now become an even busier four-way interchange, following the completion of the South Island Line (SIL) and the Shatin-to-Central Link (SCL). This paper gives some of the history of these two new lines and describes the various schemes for interchange at Admiralty, leading to the arrangement developed in the Preliminary Design, which was adopted. The main planning objective for the expanded Admiralty Station was to make interchanges between the four lines as convenient as possible, with sufficient capacity and space to avoid over-crowding. A secondary objective was that the works for the SIL and SCL should avoid any significant effects on the operation of the ISL and TWL during construction. The expansion of ADM was completed in two stages, with the South Island Line opening in December 2016, and the Shatin-to-Central Link (North South Line), opening in May 2022. It is observed that the railway system is operating smoothly, and the interchange arrangement has been well received by the public
