Type: Bus Terminal
Function & Network Role
Kowloon Station is the largest of the seven Airport Express stations and one of two Kowloon-side stations (with Tung Chung) sharing tracks between the Tung Chung Line and the Airport Express. It sits underground on reclaimed land in West Kowloon, inside the Union Square development, and opened on 22 June 1998 for the Tung Chung Line and 6 July 1998 for the Airport Express — both as part of the wider Airport Railway built to serve the new Hong Kong International Airport at Chek Lap Kok. Because it carries two separate services on shared or adjacent tracks, Kowloon Station functions less like a typical urban interchange and more like an intercity terminal embedded inside a metro network: passengers heading to the airport, to Tsing Yi, or onward into the Tung Chung Line’s residential stations on Lantau all pass through the same concourse.
History & Architecture
The station was built as part of the Airport Core Programme, the package of infrastructure projects — new airport, new highways, new bridges, new rail line — commissioned to replace the constrained Kai Tak Airport. Constructing a station of this scale required reclaiming a large tract of West Kowloon harbour frontage, onto which the station box and the Union Square towers above it were then built as a single integrated engineering exercise rather than a station with buildings added later. Union Square includes the International Commerce Centre, Hong Kong’s tallest building, which rises directly above part of the station’s footprint; the tower’s foundations and the station structure below were engineered together so that one does not compromise the other’s load paths, a coordination problem unique to stations built underneath supertall towers rather than beneath open streets. The International Commerce Centre reaches 484 metres and 118 storeys, making it the tallest building in Hong Kong and, for a period after its 2010 completion, one of the tallest in the world — a scale that would not have been commercially viable on this site without the guaranteed transit access the station below it provides.
Before reclamation, this stretch of West Kowloon was open water forming part of Victoria Harbour’s Kowloon-side frontage; the land the station and Union Square now occupy did not exist prior to the 1990s. That distinguishes Kowloon Station’s engineering problem from stations built into existing urban fabric, such as those along the older Tsuen Wan Line corridor a short distance to the east: here, the foundation conditions, utility routing and structural sequencing were all determined by the reclamation and construction programme itself rather than inherited from decades of prior development.
Local Taste & Economic Context
The commercial logic of Kowloon Station reflects its dual identity as transit infrastructure and property anchor. Union Square’s Elements mall sits directly above the concourse, and the development as a whole — residential towers, Grade-A office space, a five-star hotel cluster, and the ICC — was financed in large part through the MTR Corporation’s “rail plus property” model, in which development rights above and around a new station are sold or leased to fund the railway’s construction. This is the same commercial mechanism behind most of the MTR’s post-1990s stations, and Kowloon Station is one of its largest single expressions: the fare revenue from the Airport Express alone would not have justified the line’s cost, but the property value unlocked by reclaiming and developing West Kowloon made the whole project financially viable. Street level around the station’s older margins, toward Jordan and Yau Ma Tei, still holds the pre-reclamation food economy of dai pai dongs and cha chaan tengs serving beef brisket noodles and milk tea — a visible seam between the reclaimed high-rise district and the older Kowloon grid it was built beside rather than on top of.
Practical Navigation
Kowloon Station offers in-town check-in for several airlines, letting travellers clear check-in and drop baggage before boarding the Airport Express, which reaches the airport in roughly twenty minutes. The Tung Chung Line platforms run in the same station box and provide direct service to Tsing Yi and on to Tung Chung, the gateway for Lantau’s cable car and outlying trails. From the podium level, elevated and street-level walkways connect to the West Kowloon Cultural District’s arts venues along the harbourfront promenade, a roughly ten-minute walk. There is no direct MTR interchange to the older Tsuen Wan Line network from Kowloon Station itself; travellers wanting Jordan, Yau Ma Tei or Tsim Sha Tsui generally exit at street level and walk, since the two systems were built decades apart and were never designed to share a concourse. West Kowloon Station, the high-speed rail terminus, is a separate building roughly fifteen minutes on foot to the south.
ESG Note
The reclamation that created the site for Kowloon Station and Union Square displaced part of the original Victoria Harbour shoreline, one of a series of harbour reclamations in the 1990s that drew sustained public objection over harbour narrowing; later projects, including the West Kowloon Cultural District next door, were scaled back partly in response to that pressure. The station’s scale — engineered to move Airport Express, Tung Chung Line and pedestrian traffic simultaneously beneath one of Asia’s densest development sites — remains a reference case in MTR Corporation’s own engineering literature for integrating heavy rail directly beneath supertall construction.
