^Think of the logistics they has being open all year. They don't have the luxury of being closed all winter like most parks to refurb all their rolling stock. Couple that with budgets and trying to save $$$ and it is not surprising that they run one train. Why cut the waiting time from 1/2 hour to 15 minutes or 15 minutes to walk on and ware out a second train when most people don't mind waiting 30 minutes for a ride. This is Magic Mountain after all so waiting is expected!
