The Northern Link is a proposed rapid transit line of the MTR system of Hong Kong which would connect the West Rail Line and the Lok Ma Chau Spur Line of the East Rail Line. The link would also serve as a connection to the border checkpoint to mainland China for passengers to and from the western New Territories. The Northern Link would start at Kam Sheung Road and end at Lok Ma Chau and Kwu Tung, and would be constructed either as a direct shuttle or with intermediate stations.
Other benefits for constructing this project are that it would significantly cut journey times for certain trips (for example from Yuen Long to Fanling) and significantly reduce costs for these trips, and also relieve the large number of passengers using the East Rail Line by diverting some passengers to the West Rail Line.
According to the Railway Development Strategy 2014, a shuttle service between Kam Sheung Road Station and Kwu Tung Station spanning 10.7 km (6.6 mi) is expected to begin construction in 2018 and be inaugurated in 2023.
