The DJF1 "Zhongyuan Star" was an electric multiple unit of China Railway. It only operated in service for less than five years, before it was removed from service due to its various flaws and high maintenance costs. The train was initially built as a six car set, and subsequently lengthened to a fourteen car set. The two driving motors and the middle two motor cars have been preserved, with the other carriages being scrapped.
