The Lok Ma Chau Spur Line is the second railway link between Hong Kong and mainland China, relieving passenger congestion at Lo Wu station.
Unlike the rest of the East Rail line, which is above ground, this section is located underground.
The Government of the Hong Kong Special Administrative Region endorsed the corporation's construction of the Lok Ma Chau Spur Line on 14 June 2002.
The line was officially opened on 15 August 2007, in ceremonies led by Henry Tang, the Chief Secretary for Administration of Hong Kong.
The station box structure was first constructed as part of the Lok Ma Chau spur line but was never completed.
