If the hand-operated switch is restored to normal but has not been reported clear, what is required to re-enter the block?

The requirement for obtaining dispatcher permission before re-entering the block is rooted in safety protocols. When a hand-operated switch has been restored to normal but has not been reported clear, there is uncertainty regarding the switch's status and the safety of the block. Therefore, it is essential to ensure that all conditions are checked and confirmed, maintaining communication with the dispatcher who oversees the area.

The dispatcher has the authority to verify the switch's status, ensure that the block is clear of any trains or obstructions, and provide the necessary clearance for the train to proceed. This step minimizes the risk of accidents and keeps all parties informed of conditions on the track.

Other options, such as re-entering the block without further permission or simply waiting for a new signal, do not adequately address the potential safety risks associated with an unverified switch. Additionally, contacting local authorities is typically irrelevant in this context and would not provide the necessary real-time operational oversight needed for safe train movements.
