What is the validity of movement authority during the "void" period?

During the "void" period, the movement authority is considered invalid. This means that any previously granted authority to move equipment, personnel, or trains is no longer applicable during this timeframe. The concept of a "void" status indicates that specific conditions or procedural changes have rendered the previous authority ineffective, necessitating the issuance of new authority for any movement operations to be conducted safely and in compliance with regulations.

This aspect of movement authority is crucial for maintaining safety on the rail network, as it ensures that all activities are governed by current and valid permissions. The need for updated authority reduces the risk of accidents or misunderstandings about the operational status and requirements. Therefore, recognizing that movement authority does not hold validity at all during the void period reinforces the importance of adherence to the rules governing maintenance of way and railway operations.
