I had originally planned to use ScaleTrax before I started my layout. I had watched all of Rich Bautista’s videos on working with it and created a track plan with SCARM.
Then the bottom dropped out when I started to have trouble sourcing the track, and then shortly after that MTH announced their “going out of business” now turned reorganization. Other than a few samples I purchased to experiment with, I gave up on buying it.
I really do like the way it looks and it was priced competitively. The lack of curve options didn’t bother me because the flex track was so easy to work with.
I’m heavily invested in Ross (and some GarGraves) now so I doubt I would purchase any more, other than for displays. One thought I had was to use it in my yards to give the impression of a lighter weight, lower grade rail there, in comparison to the high-rail mainline.
another thing I’ve considered is replacing the center rail of the Ross track in the most visible portions of the layout with the center rail of the ScaleTrax, and using the left over “2-rail” ST for shelves, etc.
