The Zhan Tianyou Museum at Badaling stands at the highest point along the rail line between Beijing and Zhangjiakou. Two stories are devoted to the life and contributions of Zhan Tianyou (1861-1919), a prominent railway engineer in Chinese history.

Zhan helped build the first Chinese constructed railroad-the Beijing-Zhangjiakou Line from 1905 to 1909. He designed a double-pronged rail system and employed the “shaft construction method” to excavate tunnels. His contributions to railroad construction on a particularly tricky section of the line have inspired engineers and workers ever since.
