When limits or instructions are changed, the Track Authority form must be marked as void and replaced to ensure clarity and maintain safety standards in railroad operations. This procedure is crucial because a Track Authority form serves as a critical document that outlines the permissions for train movements within certain limits, and any adjustments to these limits or instructions could lead to confusion or operational errors if the changes are not properly documented.

Marking the form as void allows all involved personnel to recognize that the previous authority is no longer valid and protects against any potential miscommunication. Replacing the voided form with a new, updated Track Authority form ensures that the latest, correct information is in circulation, thus maintaining the integrity of rail operations and prioritizing safety on the tracks. This standard practice helps prevent accidents and operational misunderstandings that could arise from using outdated or incorrect authority information.
