West Kowloon Station is the terminus of the Hong Kong Section of Guangzhou–Shenzhen–Hong Kong Express Rail Link (XRL), and is currently under construction. It is the only station in the Hong Kong Section and will connect to the mainland China section through a dedicated tunnel. It is being constructed by the MTR Corporation.Aedas, in collaboration with AECOM, have been awarded the contract to design the multi-story 380,000 square meter terminus.WKS will be located in Jordan, Kowloon, north of the proposed West Kowloon Cultural District between the Airport Express and Tung Chung Line Kowloon Station and the West Rail Line Austin Station, extending into the underground area of the West Kowloon Cultural District.The original scheduled opening date of 2012 was delayed until 2015 following the shake-up of high-speed rail construction across China after the 2011 Wenzhou train collision. While construction of the station was still planned for completion in 2015, major flooding occurred in the railway tunnels under construction on 30 March 2014. This resulted in great damage to the tunnel boring machines. Internal MTR reports suggested causes were incomplete tender drawings, site surveys and planning before construction began. As connection of the station to the rest of the Chinese high-speed rail network is now scheduled for the 3rd quarter of 2018, some aspects of the station's construction have been slowed down or delayed. The cost of the construction also increased by around 30% more than the initial estimated.
