Choo Choo Charlie & Rich, special thanks to both of you.
Turns out that my LHS owner, Tom of Tom's Trains in Ardsley. NY, who is a great guy with a wonderful hobby shop, got the name of this accessory wrong, but you wonderful and brilliant guys go the name right and directed me to the Lionel on-line owner's manual that I needed.
This accessory is exactly what I needed and fits perfectly where I will have it on my layout. It works, and over the weekend I will position it and hook it up to my layout.
I already have the Lionel Bsscule bridge to serve as a draw bridge for the train to come to, and go from, the new peninsula on my layout. Next to the Bascule Bridge I will place this Lionel Operating Draw Bridge to serve as a drawbridge for automobiles on the road that comes to, and goes from, that same penninsula.
You can't really see the road I'm talking about in the above photo that only shows the raised Bascule Bridge, not the draw bridge. The draw bridge will cross the river where the tugboat is, and then I'll move the tugboat and a smaller barge a little further up the river.
When I have the drawbridge placed, hooked up and operating, then I will post photos of it, and a video showing it in action.
