What happens if a switch is not cut off within 5 minutes after a train is lined and ready to proceed?

When a switch is lined for a train to proceed but is not cut off within a specified time frame, it is essential for the crew to take action by notifying the dispatcher again. This ensures that there is clear communication between the crew and the dispatcher regarding track conditions and the safety of the operation. The dispatcher can then evaluate the situation, providing updated instructions or making adjustments based on the current circumstances to maintain safe train operations.

This protocol is in place to prevent any potential safety hazards that could arise if a train were to proceed without confirmed instructions or updates regarding the switch. By requiring the crew to notify the dispatcher after a specific timeframe, the railway system fosters a culture of diligence and safety, ensuring rail operations are conducted as efficiently and securely as possible.
