Quite a few years ago Bachmann sold a Remote Control Bascule Bridge in HO scale. It was one of only a few bascule (drawbridge) that have been sold, and the train approaching the bridge automatically stopped when the bridge was open. Any train that  approached the closed bridge, (using tracks that went underneath the bridge), stopped when the bridge was in the down position.

Is there any chance that Bachmann could bring back the bridge and sell some more, as it is very difficult to find it anymore and no other company has sold anything like it, except Walthers and their out-of-production bascule bridge did not have an automatic train stopping system when the bridge was open.
