Lok Ma Chau is the northwestern terminus in Lok Ma Chau on the Lok Ma Chau Spur Line, a branch line of the East Rail line of Hong Kong's MTR network, which was built to alleviate the immigration checkpoint between Hong Kong and mainland China's Shenzhen at Lo Wu station.

The crossing consists of a cable-stay double-deck pedestrian bridge across the Sham Chun River, which forms the border between Hong Kong and the rest of the PRC.

Although the Lok Ma Chau Spur Line Control Point is often referred to as a railway crossing, it is in fact a pedestrian crossing, unlike the Lo Wu Control Point, where no bus or any other public transport can reach.

Among public transport destinations from Yuen Long is also bus 968 to Hong Kong Island via the Western Harbour Crossing.

San Tin PTI offers many more connections than Lok Ma Chau Spur Line Checkpoint.

KMB bus routes 76K, 276B, B1, N73, A43P, R41, X43, 178R (R41, X43 and 178R available Events Only) and all serve San Tin Public Transport Interchange.
