There are six major land crossings in Hong Kong. Four of them (Shenzhen Bay Port, Lok Ma Chau, Man Kam To and Sha Tau Kok) are road-based land crossings, while the other two (Lo Wu and Lok Ma Chau Spur Line) are rail-based. Cross-boundary passengers can also take MTR Intercity Through Trains and cross the boundary at the Hung Hom Control Point.
