A track warrant gives you authority to occupy what?

A track warrant is a form of authority issued by a train dispatcher that specifies permission for a train or work crew to occupy a section of track. The correct answer indicates that a track warrant grants authority to occupy the main track, which is crucial for maintaining safety and operational efficiency in rail transport.

When a track warrant is issued for the main track, it ensures that the train or crew has designated permission to use that specific track segment, which is essential for coordination with other trains and preventing conflicts. This authority includes provisions such as the limits of where the warrant applies, which is critical for avoiding collisions or potential accidents.

While side tracks and yards are important parts of the rail network for various functions like loading, unloading, or storing trains, a track warrant primarily focuses on the main track where the majority of train movements occur. As such, the warrant ensures that proper procedures are followed and that the trains operate in a safe manner on the main line.
