China Railway NDJ3
From Wikipedia, the free encyclopedia
The NDJ3 "Great Wall", previously labeled the "Harmony Great Wall" is the only higher-speed diesel multiple unit that is still operating in China. It was first designed to be used for passenger transport in the 2008 Olympics, and has become a mature technology platform with export orders to Nigeria despite initial flaws related to overheating of electrical cables in the power car.
