I asked for the N Big Boy rerailer. I have ballasted Atlas flex. I find that the rerailer is not wide enough. The slots for the wheel flanges are fine. But the rerailer's narrowness makes it unstable on the horizontal plane. The edges need to extend further outward. I wish there was a better way to communicate other than RU-vid comments.
Not a problem. Message me on Cults. How much wider on each side? Just added three more versions of the 25cm long rerailer. Wider, wider and taller and even wider than that... Let me know if that works!
