The tread is flat and perfectly horizontal and parallel to the ties. The is no small filet radius between the tread and the flange. Not criticizing, just explaining. With a tapered tread the loco tends to keep itself centered on the track and not wander. With a small radius, the wheels tend to NOT pick points. It is the cross section of the tread that is square. The other view shows a circle. Ed Loizeaux
