The operation and management of urban rail transit is based on station attendant and station attendant, supplemented by operators on duty, stationmaster on duty, operation team leader and traffic dispatcher. And the direction of driving and selling tickets, mainly driving. I learned a lot about this major at school, and I am also a major. Now I am an operation waiter. I remember we studied vehicles and maintenance at that time. In a word, I have learned the major of urban rail transit operation management. If you want to get into the subway in the future, I won't say much at school. Whether it's useful or not, it's best to get the top five exams every semester.
