Railway maintenance cars are specialized vehicles used to inspect, repair, and maintain railway tracks and infrastructure. These cars are equipped with tools and equipment necessary for tasks such as track alignment, welding, and replacing worn-out components. They often travel along the tracks to reach different sections of the railway network. These maintenance cars can be powered by diesel or electricity and may include features like cranes, work platforms, and storage for spare parts. By ensuring that the tracks are in good condition, railway maintenance cars help to enhance safety and efficiency in train operations.
