DoubleDAZ posted:It's not advisable to start a grade right after the switch, so I started it after the 5" straight track. Not sure why you think you need the Red track to be at 7" when they don't cross over the bottom tracks until the curve before the switch going into the upper reversing loop. Here's a rendition done in SCARM. The Blue track is at 0" elevation, the Green track is at 7" and the Orange track has a grade of 4.1%.
The layout that I posted a picture of is from Lionel. They show the elevated section in red but do not give a height. I just picked 7 inches so I wouldn't have to adjust it in case I get some equipment that would be too tall to make it under the bridge. If I build 1/2 inch above my tallest piece off equipment and then down the road buy something that I like that's taller by 5/8 I have to adjust. Trying to avoid that.
Thank you for your service and the info
