These solenoid turnout motors are available for several Atlas turnouts as well as under-table versions. Control Box 150-56 (sold separately) allows use of standard three-wire wiring, and other single-pole, double-throw momentary electrical switches may be used (not included). Switch Machines are part of the line of Atlas HO Scale Code 100 track.
