CRRC Zhuzhou Electric Locomotive Co., Ltd. designed and developed a total of 21 vehicles in Wuhan Metro Line 1, which is a 4B group, two moving and two towing, the train structure speed is 100km/h, the maximum operating speed is 80km/h, and the third rail receiver is adopted. System. Train seats: 176 people, the maximum passenger capacity (9 people / m2): 1276 people. The train is the lightest B-type urban rail vehicle in China. It adopts aluminum alloy profile, which is about 8 tons lighter than the same type of train. This can save nearly 100,000 kWh of electricity per train per year. Ring and double S-type slab steel wheels, wheel and rail noise decreased by more than 9 decibels. At present, in the CRRC, the CRRC vehicles have received train orders for several subway projects, including Line 2, Line 2, Line 4, Line 6, Line 7, Line 8, and Line 21.
