Sham Chun River
After the "Chinese Section" was completed, through train service became available to Canton, through Sham Chun (now Shenzhen). Lo Wu station also serves as a border crossing, with a bridge across the Sham Chun River, the natural border between Hong Kong and Mainland China. Trains had to stop at Lo Wu station after Communist China closed the border and suspended the through train service in 1949.
