Yeah, I looked at bringing in the side frames on my F-3's, but again, as Mario pointed out, 3" scale inches isn't enough to be concerned with. And, it really shows off the detail of the trucks since they are a little more exposed.
If I ever really get ambitious I guess I can fill in the countersunk screw head hole in the frame tab and try to drill and tap a new hole, but the taper of the countersunk hole uses up about half the existing factory hole, so I'm not sure if JB Weld or any product would hold.
Yes, LOS is a very talented modeler and quite the weathering guru. He has weathered some of the best looking locos and cars I've seen in 2 or 3 rail (the GP-30 is only one example). I don't think the number of rails is as important as the desire to have the best representation of the prototype locos and rolling stock on your layout. I'm finding out there are quite a number of 3R guys who appreciate this aspect of the hobby as much as anyone in any gauge.
