If your looking for operational aspect over prototype at our club we do 6” center to center and that keeps us from surprisingly smacking a passing train. On O-72 and wider it should keep say a scale big boy from remodeling a 21” passenger car

I can tell you with certainty that on O90 curves at 5 1/4", the VL-BB will take out 21" passenger cars on the outside track.
