ANALYSIS FO DD-35 LOCOMOTIVE & TRUCK IN OPERATION ON NEW YORK CENTRAL R.R. TRIBES HILL 2 DEGREE 58' CURVE

This report is a study of the conditions associated with operating the DD-35 locomotive over the 2 degree, 58 minute curve involved in the derailment at Tribes Hill on February 21, 1964. The expected lateral loading considered likely to occur on the Tribes Hill curve under the most extreme conditions would give net lateral wheel load of 15.900 pounds with instantaneous peaks to approximately 25,000 pounds. This extreme value of 15.900 pounds represents only 37 per cent of the associated vertical wheel load. Analysis and test results accumulated from numerous tests, including curve negotiation of many different locomotive models and measurements of wheel stresses, axle stresses, and lateral loads, indicate: the instantaneous peak values acting over and above the base loads are not significant in rail turnover, and, lateral loadings representing 90 - 100 per cent of vertical load can be applied to the rail at a single wheel location without any indication of rail turnover or wheel climbing.
