Hi all. I built me a truss bridge that is 11 inches high. To get down to ground level from there I have read that I need a 4 degree incline. From 11 inches at 4 degrees, it's roughly 9 1/2 feet. That will put me around one full turn. Will my trains climb that on a turn or do I need to adjust it any. I haven't built the incline yet and would like to know of any alterations I need to make before I do. I run dc and dcc trains on this rail. Any input would be helpful. Thanks.
