This article describes the new EMU power car and its trials in China. The EMU was developed by the Zhuzhou Electric Locomotive Works and the Zhuzhou Electric Locomotive Research Institute. Chinese Rail (CR) considers it essential for inter-city service on high-density corridors, in a market economy where there will soon be competition from cars on newly-built motorways. It began developing a high-speed electromagnetic unit (EMU) as part of the ninth national five-year plan. Its prototype was completed at the end of May 1999. Since then, the power car has been included in a push-pull train with six trailer cars and four types of trailer. The 438-seat train has design speed 220kph, but will normally not travel faster than 200kph. Its power car weighs only 84t, due to extensive use of lightweight construction techniques. It uses microprocessors in a wide range of control circuits, whose functions include traction, braking, and fault diagnosis. Supplementary rheostatic and pneumatic braking are provided. Automatic train protection takes the form of an LKJ-93 speed monitoring and recording system for use on routes with the relevant track equipment. The EMU has run on the Guangzhou-Shenzen route for verification trials. An improved, more advanced 200kph electric locomotive is planned.
