When trains are required to report clear of a main track, what must the report include regarding the switch?

When trains are required to report clear of a main track, it is essential to provide assurance that the switch is "lined normal and locked." This ensures that the switch is set to direct trains safely onto the main track rather than into a siding or an incorrect route. By indicating that the switch is lined normal, it communicates to control personnel that it is in the correct position for train movements on the mainline, which is crucial for maintaining safe and efficient operations.

Furthermore, stating that the switch is locked reinforces the idea that it is secure and will not inadvertently shift position, preventing potential accidents or misrouting of trains. Overall, this communication is vital for maintaining operational integrity and safety on the railway.
