What procedure must a train in non-signaled DCS territory follow to make a reverse movement?

In non-signaled DCS (Digital Communication System) territory, it is essential for a train to follow established procedures to ensure safety and communication. The correct answer emphasizes that a train may only reverse if it has received authorization from the Dispatcher and must adhere to specified protocols.

This requirement is in place because the lack of signals means there are no visual indicators that a train is safe to reverse. Consequently, communication with the Dispatcher becomes critical; they are responsible for providing the necessary clearance and ensuring that the track is clear for the reverse movement. Following these protocols safeguards against potential collisions and helps maintain orderly train operations within the territory.

This system of checks and balances is vital for safety, as reversing without proper authorization or protocol could lead to dangerous situations, including conflicts with other trains or obstructions on the track. Thus, the requirement for prior authorization and adherence to specific procedures ensures that all movements are coordinated and safe.
