The maintenance and repair of rail vehicles are interrelated and complementary, working together to ensure the normal operation and extend the service life of rail vehicles.
Definition and distinction of maintenance and repair
Maintenance and repair play different roles in the maintenance of rail vehicles. Maintenance refers to the regular maintenance and protection of rail vehicle components to ensure their normal operation. Maintenance includes preventive measures such as cleaning, tightening, adjustment, and lubrication, aiming to extend the service life of components and improve vehicle performance. For example, daily maintenance includes cleaning the vehicle body, tightening screws, adjusting mechanical components, and lubricating key parts.
Repair, on the other hand, refers to the repair of damage or faults that have already occurred in the rail vehicle, usually after a vehicle malfunction. Repair may involve replacing severely worn components, repairing damaged mechanical structures or electrical systems, etc.

Importance of rail vehicle maintenance and repair
Maintenance and repair are crucial for the normal operation and extended service life of rail vehicles. Through regular maintenance, potential problems can be identified and solved in a timely manner, preventing failures and ensuring that the vehicle is always in good condition.
