I am considering using 3 Lionel 104 bridge spans as pictured below, but probably with taller supports and and a lower base. The inside width is only 5", which I consider a bit close for engines such as my 392E. I am considering shimming out the green sides about 1/4" or more on each side. Am I being silly, or is this a good idea? I don't want to go to the trouble if I am not likely to have a problem. I think my biggest concern is that someone, someday may want to run their special engine on my layout and the bridge may be too narrow.
