Following the population growth, the rail can extend northward to Sha Tau Kok, adding an additional land crossing by train. Or, it can simply extend to the west connecting Lok Ma Chau Spur Line, to provide rail service for the new development at Queen’s Hill and Fanling North New Developments Areas as well as cross-border passengers via Lok Ma Chau and Lo Wu.
To ease the burden of East Rail Line, this new north-south rail route has the potential to link up Ma On Shan with Tseung Kwan O, via Sai Kung and Hong Kong University of Science and Technology. As a result, passengers on the island side may take MTR to Mainland China via North Point, Tseung Kwan O, HKUST, Sai Kung, Ma On Shan, Plover Cove New Town, Queen’s Hill, Fanling North and Sheng Shui
