What difference do higher rails and swinging pilots make, apart from looking awful..??! In my video above, my Atlas SD40 takes my 36" radius curves on Code 125 2-rail, hand-spiked track, with no issues at all.
*Edit - have now gone back to my post further up and embeded the two videos I really want Unbelievers to see.
36 radius in 2R is O72 diameter in 3R. Thus, we still work with much tighter curves. For example, I ran my Lionel Sd70ace around my Christmas tree using o36 (18 diameter). It had a lot of overhang on curves, but it was a ton of fun. It would look a little better on 3R o48 or o60, but in a pinch it works. With that said, using regular couplers instead of the 3R lobster claws and fixed pilots, running a 6 axle diesel on my equivalent of o72 is still impressive.
