’’Pioneer’’200km/h power separated type AC transmission EMU, listed in the National Ninth Five-year Plan as key project, is the first series of AC power separated transmission EMU with maximum running speed of 200km/h and maximum testing speed of 250km/h. This EMU consists of two units totally six wagons, each unit consists of 3 wagongs, including two driving wagons and one driven wagon. The EMU is equipped with one first class wagon with soft seats, and five wagons of second class, for fixed passengers of 424 in total. 

The domestic produced EMU first adopts advanced control systems, such as the AC-DC-AC trans-mission system, microcomputer controlled direct electro-penumatic simulating type braking system and microcomputer network control system. Furthermore, it adopts new type units such as new type traction transformer, IPM current trans-former set, asynchronous traction motor, powered bogie without bolster, non-powered bogie, electric powered and pneumatically controlled sliding doors, induction internal end doors and vacuum toilet waste discharge devices, etc. 

In the train there are cabs for diver, cabinets for conductors, electric power distribution, broadcasting, washing, toilet and cleaning-wares as well as snack counters and telephones. The wagon body is of a cylindrical structure with integrated-load bearing without a central beam and all-welding structure. A streamlining type structure is adopted at the front parts of the first and last train wagons. The lower parts of trainsets of each wagon are epuipped with skirt plates made of aluminum alloy. Air conditioning system operates in all seasons, which has the function of concentrated control for air conditioning.
