Thank you, Bob, Greg, Richie!
Bob, the height is a shade over 7 inches. The length of the slope is only 18 inches. Yes, your El does add a wrench in the works! Your scenes do have a lot of detail as they are!
Greg, yes Canton Avenue is steeper, but I think Rialto is a longer slope. Center Street in Duquesne is steep as well. I have never driven any of them myself. You are right that steep rural roads usually have twists and turns. The section of board I used has a slight turn near the bottom. I’ll want it to turn more when I actually build it.
