How will restricted limits be designated?

Restricted limits are designated by points specified by signs and instructions to provide clear guidance on where such limits begin and end. This method ensures that all personnel working in or near the tracks are aware of the specific areas where special rules apply, promoting safety and maintaining operational control. These signs and instructions serve as a standardized, visual representation of where restricted limits are in effect, allowing for quick and unambiguous identification that everyone can follow regardless of verbal communication or individual interpretation.

In contrast, while verbal instructions from a foreman may be useful for temporary or immediate situations, they are not a reliable or consistent method for designating restricted limits over time or for all personnel. Markings on the ground could vary significantly and might not convey the necessary information clearly or uniformly. Relying on signals from other trains does not provide a definitive or safe framework for establishing restricted limits, as those signals are typically used for operational communication and do not serve the purpose of designating areas of restricted limits.
