Introduction to the China Rocket Model: The "China Rocket" or "Dragon" model made at a 1:1 scale is one of the earliest steam trains operating in China. The black body is decorated on each side. There is a golden Chinese dragon on top, and the rails laid underneath are taken from Kangzhuang in Yanqing, a suburb of Beijing. It is an integral section cut from the Beijing-Zhangjiakou Railway, China's first self-built railway designed and supervised by Zhan Tianyou.
