Archimedes Track Switching

Archimedes Sensors The sensors indicate the location of the train and will be needed for: Crossing gate Lights Track switching The sensor starts off with a reed switch that will close when it senses a field from an external magnet. Magnets will be attached to the bottom of all the train’s cars.
