The main reason railroad trains remain on their tracks has to do with the ____________________. A) None of these.B) beveled shape of the wheel circumference.C) independence of opposite wheel motions.D) All of these.
E) flange on their wheels.

    The flange keeps the wheels on the track when negotiating a curve. The beveling effectively provides slightly different diameters so that the inside and outside wheels can move at slightly different speeds on curves, so that a differeential is not needed. See
