The CRRC Zhongzhu Metro Line 1 Metro B-type vehicle has a total of 35 columns, 4 moves, 2 tows, 6-segment, wide-body drum-type aluminum alloy vehicles, and the train has a top speed of 80 kilometers per hour. The train adopts all-welded aluminum alloy body technology, based on the air brake technology of tread braking, and intelligent air duct system technology. The main safety and reliability, energy saving and environmental protection, green low carbon brand, unlike the previous subway, the first use of overvoltage protection resistors in the traction braking system, to play a balanced energy feedback when the vehicle brakes. Through the technology of weight reduction and energy-saving system integration, the Zhengzhou rail transit vehicles with six sections are nearly 10 tons less than traditional rail transit vehicles, saving up to 100,000 kilowatt-hours per year. At present, the CRRC Zhongzhu machine has received train orders for several subway projects such as Line 2, Line 2, and Line 5 in Zhengzhou.
