Oh the humanity! I think you’re right though. I turned my track upside-down and tried to look inside that gap, as far as I could tell it was only metal, but your pic clearly shows that there’s plastic inside there. The change in thickness of the rail there shouldn’t be enough to derail it, at least not at lower speeds. Sweet! You sure BRUTALLY MURDERED that piece of curved track though, all the train people of the world will be having nightmares. You should still bring the track pieces to the Jan 6 meeting so we can see them.
