Train time is a big event at stations equipped with this system that uses your train names or numbers, plus the names of arrival and destination cities on your O-, S- or HO-layout! Small barcodes placed under a baggage or passenger car automatically identify up to 16 different trains on two thru- or dead-end tracks. Unit senses each train's direction of travel to make appropriate announcements. Trains can be restarted manually or automatically with a built-in auto (timed) release. And since the unit is speed sensitive, fast express trains just roll by.
