The only difference is the scale coupler, electronics, and the wheels being all flanged. The Kadee couplers have slightly closer coupling. You probably could get a two rail version to go around a shorter radius with a long shank Kadee coupler. However, having all three axles flanged is the real issue I believe. When I modified an MTH GE 6 axle so that all the axles had flanges it no longer would go around an 072 curve. Having said all that, I understand that 3rd Rail 2 rail locomotives run on a 48" radius if the track is laid well.
