Kowloon Southern Link

Project Description

The Kowloon Southern Link (KSL) will link the existing East Rail Line's East Tsim Sha Tsui Station with the West Rail Line's Nam Cheong Station, connecting these two lines at the southern end. This new 3.8 km long rail link aims to serve the strategic function of allowing passengers of West Rail Line to have direct access to East Rail and vice versa, and will have one intermediate station – West Kowloon Station. The Government of the Hong Kong SAR gazetted the authorised KSL scheme on 24th June 2005.

The KSL civil construction works are packaged into three major contracts: West Kowloon Station and the railway tunnels from Jordan Road to East Tsim Sha Tsui Station; the railway tunnels from Jordan Road to Yau Ma Tei Ventilation Building; and the railway tunnels from Yau Ma Tei Ventilation Building to Nam Cheong Station.

The railway tunnels running along Canton Road and Salisbury Road between West Kowloon Station and East Tsim Sha Tsui Station will be constructed using a Tunnel Boring Machine (TBM). The new West Kowloon Station will be located in the West Kowloon Reclamation Area, and will feature an underground concourse and an island platform (a central platform with tracks on either side). The tunnels north of West Kowloon Station from Jordan Road to Nam Cheong Station will be constructed using cut-and-cover methods.

Upon completion, the KSL will help provide a direct link between the Northwest New Territories and Tsim Sha Tsui. It will take only 30 minutes to travel from Tin Shui Wai to East Tsim Sha Tsui.

The railway will be constructed in a highly developed urban area of great significance in both commerce and tourism. The tunnel works for the southern section will be constructed adjacent to the Hong Kong Cultural Centre and Space Museum and a number of prestigious hotels and other buildings, all of which are highly susceptible to noise and vibration. Therefore, construction techniques which minimise the transmission of noise and vibration will be used.

In addition to the KSL railway works, the existing pedestrian subway along Middle Road in Tsim Sha Tsui will be extended westward to Kowloon Park Drive where it will connect to two existing Government subways. The extended subway will significantly enhance the connectivity between the East Tsim Sha Tsui Station and the Canton Road area.


Civil construction of the KSL commenced in the fourth quarter of 2005. Access to project contractors for trackwork and railway systems installation will be provided from the latter half of 2007. Completion of the KSL project with West Kowloon Station open for public use is scheduled for 2009.

Progress Update – March 2008

The West Kowloon Station structure was substantially completed. Building services and architectural works were 38% completed. The tunnel boring machine (TBM) completed the final tunnel drive between the West Kowloon Station and the existing East Tsim Sha Tsui Station with the tunnel breakthrough ceremony held on 12 March 2008. The cut-and-cover tunnels north of the West Kowloon Station were 89% completed. Overall completion is expected in the second quarter of 2008. Track laying was 63% completed.

Six sets of new 7-car trains are undergoing high speed dynamic test. Manufacturing and testing of major electrical and mechanical equipment have been substantially completed and delivery of equipment being made progressively to Hong Kong. Electrical and mechanical system installation has commenced in West Kowloon Station and trackside installation is scheduled to start in the third quarter this year.
