OK, we have a good progress with MTH RealTrax library for SCARM, thanks to Steve and Jefrey
Today, I updated the preliminary library file in the blog and now it should have all tracks and turnouts. I also corrected the radii of O-31 and O-42 curves, as the old values was slightly larger. I used the new Background Image feature in SCARM to check the library against several track plans found with Google and they all fit in SCARM without problems. However, a real tests (with real tracks) are still needed to verify that geometry and dimensions are correct.
So download the updated SCARM lib from the blog post and try it
