That is a good idea, the RR crossings here do that as well. There were two intersections like this right by our old home of 35 years before we moved a little further west in 2013.
I get the idea, not sure I know how to accomplish it, but will give it a try. Something to fiddle with anyway. Will post back here with results one way or the other. Don't go away, in case I get stuck...
Thanks to both of you for all the help so far.
