While the outlines show modern theory is that coning does harm rather than good,so far as curve work is concerned. The cone, however, has a real advantage in steadying thetrucks on tangents and preventing them from running fromside to side or hunting. Coning, to some extent, also re-duces flange wear on ordinary rails. It is something of aquestion, however, whether a coned wheel is of any advan-tage on a grooved rail where the groove allows only Standard Face and Flangeof 30and , 4 ft.

It adds strength at the very point where it is mostneeded, making the flange much better able to resist shocksof all kinds and tending to prevent the annoying droppingoff of large sections.

Coning was formerlysupposed to be an advantage in enabling wheels placed play to the wheels at best and where dirt, etc., practicallyleaves the wheels without play. Under such conditionshunting is out of the question. In many cases the wheeltakes its bearing at the bottom of the groove. The wear of wheels on curves has long been a studyamong stea
