If a train operator notices a white light being waved on the track ahead, what is the signal to do?

When a train operator sees a white light being waved on the track ahead, it is a signal to slow down and prepare to stop. This signaling is typically used to indicate a potential danger or an obstacle on the track. The white light indicates that the operator should proceed with caution, reducing speed to ensure the safety of passengers, crew, and equipment. Understanding this signal is crucial for maintaining safety protocols and responding appropriately to changing conditions on the track. It helps operators to be vigilant and ready to address any situations that may arise, ensuring the train can come to a safe stop if necessary.
