1. What is cab signalling and why is it important for trains?Cab signalling is a system that sends signal information straight into the train's driver's cabin. It helps keep trains safe by giving the driver clear instructions about speed and track conditions.
2. How does cab signalling help trains stay safe when the outside signals are hidden?When outside signals are hidden by fog or snow, cab signalling still works because it sends continuous updates to the driver. This way the driver always knows what the track ahead looks like.

Signal Passed at Danger (SPAD): An incident where a train passes a signal that indicates danger or stop.
Automatic Train Protection (ATP): A safety system that automatically intervenes to stop a train if it exceeds safe operating parameters.
