Maintenance and repair of railway locomotives and rolling stock
Maintenance is crucial for preserving the performance of railway locomotives and rolling stock, and is primarily categorized into routine maintenance and periodic maintenance. Routine maintenance mainly includes regular inspections, refueling and lubrication, and cleaning. Periodic maintenance, on the other hand, involves in-depth inspection and maintenance of the vehicle's various systems, including the engine, braking system, and suspension system. The maintenance cycle and content vary depending on the vehicle type and operating environment. In practice, maintenance personnel must perform the necessary work according to the vehicle's operating conditions and the requirements of the maintenance manual.
