1. The flange rarely ever touches the rail and curves are mostly handled by the taper on the wheels and are rarely ever handled by the flange..
2. The flange DOES touch the rail on curves and the taper is only there to help centre the wheelset on straight tracks and is not enough to act as a differential.
3. The flange touches the rail on curves, and the taper is there to help centre the wheelsets and to allow the wheels to spin independently on curves a bit like number 1 except the flange always touches except for straight tracks and GIANT curves.
What is correct?
