The purpose of this guideline is to consider the aspects that result in failed communications and to establish a range of guiding principles to assist in mitigating the risk of such failures by providing Rail Transport Operators (RTO’s), and associated rail industry stakeholders, with a range of processes and practices they can adopt and use for their operations.

This Guideline is outcome focussed, rather than being prescriptive in nature. It does not seek to mandate particular systems, processes or technologies, but focuses on outcomes, leaving the method up to individual network managers.
