REQUIREMENTS FOR THE RELIABILITY ASSESSMENT OF RAILROAD RAIL IN SERVICE

The increasing occurrence of defective railroad rail and the associated increase in train accidents has emphasized the need, both from safety and operation viewpoints, to consider the statistical character of rail failure. Even though wheel-rail contact stresses play a central role in many significant railroad problems (wear, traction, guidance, braking, headway, etc.), an adequate understanding of these stresses still eludes us. The complexity of the problem was illustrated, and the current status of knowledge was reviewed in such areas as: conformal contact (worn or "profiled" wheels), rolling contact, adhesion, creep, plastic flow, residual stresses, and surface roughness effects. Sources of information on these and related areas were identified, and physical and geometrical plausibility arguments were used to describe a number of major results which have been achieved by complex mathematical procedures.
