What information must a Dispatcher provide to trains experiencing a wayside cab signal apparatus outage?

In situations where there is a wayside cab signal apparatus outage, one of the key responsibilities of a Dispatcher is to ensure that trains are informed about the extent of the outage. The limits of the CSS (Cab Signal System) outage indicate the areas where the signal system is not functioning and therefore cannot provide the necessary information to the train crew for safe operation. By providing this information, Dispatchers help ensure that train crews can exercise caution and properly adjust their train operations in accordance with the current signal conditions. This is critical for maintaining safety and efficiency on the rail network.

Knowing the limits of the outage allows train crews to plan their movements accordingly, ensuring they take appropriate measures, such as reducing speed or being prepared for manual operations or signal indications that may differ from automated systems. This information effectively allows crews to implement safety protocols to mitigate potential risks while navigating through areas affected by the outage.
