WHEEL-RAIL DYNAMICS OF LOADED ORE CARS ON THE Q.C.M. AND B. AND L.E. RAILROADS

This study was initiated to determine the possible cause and to recommended a practicable remedy for excessive wear and damage to rails on the Quebec Cartier Mining Company Railroad. Using instrumented car trucks and trackside rail deflection indicators, measurements of wheel-rail dynamics were made during test runs on the Bessemer and Lake Erie Railroad to evaluate the effect of different cars, car-truck combinations, and track structures on the forces between the wheels and the rails. The primary causes of the severe rail damage and rail corrugation experienced by the Q.C.M. are the unit train method of operation in conjunction with the undesirable car behavioral traits inherent in the design of the trucks of the standard Q.C.M. car. The effects of "bouncing", "rocking", "hunting", and "oscillation" of cars on tangent track, and of the "skewing", and "unbalance" on curves were measured quantitatively.
