What is required to make a reverse movement within the limits of the block in 251 Territory?

To make a reverse movement within the limits of the block in 251 Territory, obtaining a Track Authority is essential. This is part of the safety protocols in railway operations that ensure all movements are communicated and authorized, preventing conflicts on the track. A Track Authority provides clear permission for a train to occupy specific limits of track and indicates that proper safety measures have been followed, ensuring that there are no other trains on those tracks that could lead to a hazardous situation.

This requirement also helps maintain an organized flow of train movements and reinforces the importance of communication and adherence to regulations during operations. While notifying the dispatcher, crew member permissions, and other details are important parts of overall train operations and safety, having a Track Authority is the key step specifically required for making reverse movements in this context.
