Hi all. Sorry if this has been asked before:
Have you run an Atlas 4-axle 3-rail diesel, like the U23B or C424, around an O-31 curve? I know they list O-36 as a minimum, but maybe that's only because it won't clear O-31 switches? My smallest switch is a Gargraves O-42, but I have some smaller curves (actually Gargraves O-32 sectional.)
Again, I know what the "official" minimum is, but I'd like to know if anyone has run these engines through anything smaller. Don't worry, I won't rat you out.
Thanks,
Alan P
