OBSERVATIONS ON THE EFFECT OF HEAVY WHEEL LOADS ON RAIL LIFE

The Bessemer and Lake Erie Railroad has operated 90-ton open-top cars since 1931 and has some statistics on rail wear and rail life under the stresses imposed by such equipment. Rail life on tangent track has been around 440 million gross tons for jointed rail and beyond 650 million gross tons for continuous welded rail. Statistics are also available for Curvemaster and controlled cooled rail on curves. On newer ore carrying railways, rail life appears to be appreciably shorter. Among possible reasons are the bidirectional operation of loaded trains on B&LE, the mixing of various capacities of cars, and the predominance of traffic on solid, rather than roller-type, journal bearings.
