D. SUMMARY: This three-part video shows the operation of an S gauge automatic passing siding, showing it controlling 2 trains on the same track. The system uses magnets on the bottom of the locos/cars to activate a reed switch, which activates an automotive relay, which then throws the American Flyer turnouts. Automotive relays are used to handle the large amounts of current (estimated about 6 amps) required to operate a pair of American Flyer switches.
