    2. High Speed Train

    (1)China high speed train has four major series, which have axle loads ranging from 14t to 17t and can realize 200-350km/h operation. Based on these trains, CRH380 high speed train is developed, it has axle load of 15t, operational speed of 350-380km/h and the maximum test speed of 487km/h. By Nov. 2012, total 267 sets of CRH380 EMU are rolled off the assembly line, among which one is an high speed comprehensive inspection train.

    (2)High speed train has characteristics as low-resistance streamlined head, air tightness car body, matched vibration mode, reliable bogie system, low noise, high-performance traction system, current collection with two pantographs, safe braking system and human-based passenger interface.

 
    3 . HSR Communication & Signaling

    CTCS-3 train control system is constructed for China HSR, including temporary speed limit server, RBC, onboard train control device, etc.
