The functioning of wheels and rails as a supporting and guiding system depends on a Hertzian contact of 0.2 in/in area. In addition to its supporting function, this area must withstand tangential forces to enable the functions of traction, braking, and guidance to be fulfilled. Such traction forces are accompanied by a deflection known as "creep" and classical estimates of this quantity are compared with measurements made on the track. Modes of wear of wheel and rail are described and alternative systems which avoid contact are discussed.
