Which statement is true regarding the movement of a train when given a track warrant?

The statement regarding the movement of a train when given a track warrant that is true is that the train must move only in the direction specified in the track warrant. A track warrant is a form of permission that provides specific instructions regarding where a train can operate on the railroad. These instructions are critical for maintaining safety and coordination among trains on the track.

When a track warrant is issued, it generally stipulates the exact limits of movement for a train, including the direction of travel and any specific conditions or restrictions. This ensures that trains do not encounter each other on the same track, thereby reducing the risk of collision. Following the specified direction is essential for the safety of crew members, other trains, and the infrastructure.

In contrast, the other statements suggest either a more lenient interpretation of the authority of the track warrant or imply that safety protocols can be ignored under certain circumstances. However, safety regulations prohibit disregard for the official directions given in a track warrant, underscoring the importance of strict adherence to the instructions to ensure safe railway operations.
