Shek Chung Au was historically an important traffic node, and a military post was located there during several hundred years, until the mid-19th century. In 1911, the
Sha Tau Kok Railway was opened as far as Shek Chung Au. The light railway was then extended to Sha Tau Kok in 1912. Shek Chung Au Station () remained as one of the five stations of the line. On 15 February 2012, areas around Sha Tau Kok (but not the town itself), as well as Mai Po, were taken out of the
Frontier Closed Area, opening up of land for public access. A checkpoint on the original perimeter, operated by
the Police and the
Customs and Excise Department at Shek Chung Au, was officially decommissioned on 14 February 2012, and its functions taken over by a new checkpoint outside of Sha Tau Kok. ==See also==
