I'm planning a new Ntrak module. I've settled on a design I like, but would like some input on it. It's based on a section of I55 and US66 with some "artistic license" taken. (The UP AFAIK never had a 3 track main, for example.)
For those with CadStd, you can download the original document here. The one I've settled on is the upper right design. If you want to use the track and module designs for non-commercial purposes, feel free. (I still own the copyright, though.)
