A train yard is a designated area where trains are stored, maintained, and organized. It typically includes tracks, loading docks, and facilities for servicing locomotives and freight cars. Train yards play a crucial role in the transportation network, allowing for the efficient transfer of goods and passengers. In a train yard, trains can be assembled or disassembled for different routes. This area may also feature equipment for loading and unloading cargo, as well as maintenance shops for repairs. Overall, train yards are essential for the smooth operation of the railway system, supporting both freight transportation and passenger services.
