Which term refers specifically to tracks used for storage and making up trains?

The term that specifically refers to tracks used for storage and making up trains is "yard track." Yard tracks are designated areas within a rail yard where train cars can be assembled (made up) into trains, stored when not in use, or prepared for maintenance. These tracks facilitate the organization and management of rolling stock, allowing for efficient operations in rail systems.

In contrast, controlled track typically refers to sections of track that are managed for train movement under strict regulations, ensuring safety and organization. Main track refers to the primary track where trains operate regularly, linking various locations along a railway network. Working limits indicate a designated area in which maintenance or other work activities can be performed, ensuring the safety of maintenance personnel while trains are not expected to pass through. Therefore, yard track is the most accurate term for tracks specifically designed for the storage and assembly of trains.
