Yes it does. Layers, elevations, grades… The only problem I had with it was the lack of included support for tubular O gauge track but for all I know I’m the first person to ever miss that. That’s fixable with the custom definitions. It’s a pretty serious package. Give it a whirl and I’m sure you’ll like what you see.

Dave,
Does this software allow layers? I would love to put down the layout I had as a kid. My Dad built it.

It was a large "U" shaped layout, with the yards on the right and an elevated section + turning loop (lower level) on the right.

Dad built all the bench work himself in ~1960. Some of it survived until we sold the house.

Hope you are having fun with your trains!
