locomotive mounted tablet catcher pk of 10 please see my other auctions for the locomotive mounted catchers A train tablet catcher system uses physical tokens called "tablets" to control traffic on single-line railway sections, ensuring only one train can use the line at a time to prevent collisions. The system involves tablets held in machines at stations and mechanical catchers mounted on locomotives and ground-based pillars, allowing for high-speed, automated exchange of tablets between trains and signal boxes without requiring the train to stop.
