When two trains cross each other, loco pilots wave green flags as a safety protocol. This practice ensures clear communication between the pilots, confirming that both trains are on the correct track and proceeding safely.
The green flag signals that the track ahead is clear and that the train can continue its journey without any obstructions. This visual confirmation is crucial, especially in areas with limited visibility or complex track layouts.Â
By waving green flags, loco pilots uphold a tradition that enhances safety and coordination on the railway network.
