I can’t speak for that particular locomotive, but I got my hands on a Hudson with that same set up, and even on O81 Atlas track, you could tell the flanges were fighting it.....I had no issues traversing switches, or obviously on straight track, but that thing in a curve, and you could hear it just cryin away till it came out....your results may vary, some others have mentioned they had little to no issues on Fastrack, but I’ve never owned any Fastrack,...and I’d imagine old school tube track just ain’t happen in’ .....
