The swing bridge is a common sight on rivers and industrial canals across America. In the spirit of the #213 Lift Bridge, the all-new Lionel Swing Bridge keeps traffic on your O gauge river and rail systems running smoothly. At the press of a lever, the entire bridge span pivots at its mid-point, allowing boat traffic to pass below. Press the lever again and watch the bridge swing the rails back in line so that the awaiting fast freight train can barrel across the river. Twelve navigation lights below the bridge warn vessels passing below of the bridges position.
