If a train has a track warrant from Anna to Cloy and reports complete by Bess, what happens to the track warrant?

When a train operating under a track warrant reports complete at a specific location, it indicates that the train has completed its authority to move on that segment of track. In this scenario, the train has a track warrant from Anna to Cloy and has reported complete by Bess. This means that the train has reached Bess, which is between Anna and Cloy.

Due to this completion report, the authority granted by the track warrant is terminated between Anna and Bess. Therefore, the track warrant is considered void for the segment of the track between those two points, which makes option C the correct explanation.

The authority beyond Bess toward Cloy remains valid unless the train continues its authority or reports complete again further along the route. This condition upholds safety protocols and ensures that no conflicting movements occur where the track authority no longer applies.
