Add this matching boom car to take command control railroading to a whole new level. Listen as the diesel engine sputters and comes to life. Turn the cab or lower the hook, and hear the gears or winch engage. Deploy the outriggers and hear the sounds of steel girders snapping into place. Each effect is synchronized to the action of the crane car. Listen as the crane operator takes directions from his foreman, who sometimes just shouts a cautionary reminder of “Safety First!"
