John Parsons started very young with an American Flyer train set. He was intrigued by wig-wag signals at grade crossings near his home and by age four made wig-wag replicas with Tinker Toys. He has been on a mission ever since to improve the realism of model railroad signal operation in a way that's accessible to the average modeler.  John is the instigator and owner of Azatrax.
