What authority is required for a reverse move in an interlocking?

A reverse move in an interlocking requires both a proper interlocking signal aspect and permission from the block operator to ensure safety and coordination among all train movements.

The proper interlocking signal aspect is critical as it indicates whether it is safe to proceed with the reverse move. This signal provides essential information about the track ahead and any potential conflicts with other trains or movements.

Additionally, obtaining permission from the block operator is crucial as it ensures that the operator has acknowledged the move and has taken necessary precautions to protect the area. The block operator is responsible for managing train movements within their block, and their authorization ensures that there is no risk of conflicting movements that could lead to accidents.

Together, these requirements are designed to enhance safety protocols and reduce the risk of incidents during reverse movements. Adhering to these procedures safeguards the personnel involved and maintains efficient operations within the interlocking system.
