What rule number is associated with the RVDS system in Sydney Trains?

The rule number associated with the RVDS (Road Vehicle Detection System) in Sydney Trains is NSY500. This rule is crucial as it outlines the operational guidelines and safety protocols concerning the detection and management of road vehicles near railway tracks. Understanding this specific rule is important for ensuring compliance with safety standards and minimizing the risks associated with vehicle interactions in proximity to the rail corridor.

The other options, while they might reference different systems or rules within the organization, do not pertain to the specific guidelines that govern the RVDS. Thus, NSY500 is identified as the accurate rule because it directly relates to the operational framework that personnel must adhere to when dealing with the RVDS in the context of train and road vehicle safety.
