What should the train crew do before entering the limits of overlapping authority?

The correct response emphasizes the importance of communication and safety protocols that train crews must adhere to when approaching overlapping authority limits. Before entering these limits, the train crew should actively seek permission from the employees who are authorized in the overlapping area. This step ensures that the crew is operating within the guidelines of their authority and that they have the necessary clearances to proceed safely.

Overlapping authority refers to the regions where the operational control of two different entities might intersect, such as different railroads or track sections managed by different authorities. Seeking permission is a critical safety measure that helps prevent accidents and ensures coordination between the crews responsible for the respective segments of track. Ensuring that the crew communicates and receives proper authorization demonstrates adherence to industry regulations and promotes safe operations within the rail system.
