CLEARANCE ALLOWANCES TO PROVIDE FOR VERTICAL AND HORIZONTAL MOVEMENTS OF EQUIPMENT DUE TO LATERAL PLAY, WEAR AND SPRING DEFLECTION

A study on a method of ascertaining the lateral displacement of a moving car due to track irregularities and the dynamic behavior of the equipment is discussed. The results of an analysis of running test tracings on 8 passenger cars with different truck types is shown. The angular variation noted is a function of speed. A comparative tabulation of lateral displacements of the cars at a point 11 feet above the top of rail, based on the cars moving at 70 mph and at 3-in. unbalanced elevation is presented.
