Why Train Drivers Swap Rings

Показать описание
Have you ever noticed that train drivers often exchange a metal ring with a worker before passing through a section? Well, it’s not just random. Actually, That metal ring is called a pilot token or staff, and it serves as official permission for a train to enter a specific section of track. This system ensures that only one train occupies a stretch of single-track railway at a time. The token swap between drivers ensures clear communication and coordination between train movements and helps prevent head-on crashes on single-track lines. but the tricky part is that it often has to be handed over while the train is still moving.
