Great idea if I had the time. There is a working model of one that still exists on the New Haven done in HO (I think) that is shown every year at the Amherst Railway Society’s Big Train Show at the Big E (Agawam, MA). Took the guy 5 or ten years to build. Even in HO the thing is HUGE.
My indoor bridges are much more utilitarian. The one in the picture is bare bones. The new one is a lot prettier, made of pre-finished boards (an old water bed frame) with nice rounded edges. If I were to paint it gray, it might pass for a concrete structure.
So the Bascule will have to wait until I retire, and then it will be built in Z (with the aid of a microscope) 'cause when I retire we plan on converting this house into one with 10 wheels and a big diesel engine and spend all our time traveling. That is if gas stays under $50/gallon :o
