I ended up with 2 Williams scale GG1s. GRJ installed PS3 boards in them. I got the Williams models instead of MTH specifically because they will do O42 curves. But as Gene mentioned, they do have quite a bit of overhang. I didn’t like the massive overhang on my tighter curves so I only run them on wider loops. But even on the widest loop, there is one spot where the overhang causes a clearance problem. I put a sign there to keep from ripping the pantograph off. I have run them on inclines of 3% without problems. You should get one Foxer. They look a lot better than the semi scale version.
