Problems solved by technology
Because the cost of a single set of subway and light rail vehicles is about 5-30 million yuan, using the original vehicle for training is risky and costly, the production cycle is not allowed, there are many uncontrollable factors, and due to the limitation of the quality management process system, it is impossible to understand more deeply Control Principles of Subway and Light Rail Vehicles
The above situation seriously restricts the improvement of the operation skill level of the commissioning staff, and has become a restrictive factor for the production of subway and light rail vehicles
