What must happen if an Acses fault requires monitoring but not a cut-out?

When an Acses fault requires monitoring but does not necessitate a cut-out, the correct action involves notifying the relevant departments and ensuring that trains are limited to a speed of under 79 mph. This procedure is essential for maintaining safety and operational integrity while the fault is being monitored. Limiting train speeds helps prevent potential hazards that may arise due to the fault while still allowing train operations to continue, ensuring service is not completely halted.

By notifying the relevant departments, communication channels are maintained so that all necessary personnel are aware of the situation. This collaborative approach allows for a prompt response should the fault worsen or require more urgent measures. Keeping trains under a specified speed threshold acts as a safety precaution, minimizing risk until the situation is appropriately addressed.
