WHEEL, AXLE, AND RAIL STRESS PROBLEMS RELATED TO HIGHER CAPACITY CARS--PART IV-EFFECT ON RAIL

Those items that have been found advantageous in reducing shelling caused by higher capacity (85 to 100-ton) cars are wheel loads should be limited in proportion to wheel diameter. Higher strength material in the rail will greatly reduce shelling but not entirely eliminate it (under the wheel loading conditions existing with 70-ton capacity cars before the allowable load was increased 5%). Modified rail head contours in today's modern rail sections which approach the average worn wheel condition, have been helpful in reducing shelling. Rail lubrication on curves extends the rail life but results in the removal of more rails for shelling rather than abrasive wear.
