I picked up the Bachmann Disaster Crossing for N Scale at a yard sale - Item #56-1201. It's a car that stops on the tracks at a railroad crossing, causes the train to stop, is towed away by a tow truck, and the train continues on. There were no instructions in the box. Is anyone familiar with this item? I'd like some information on it before I test it out and ruin it. Thanks for any help.
