A general static analysis, including the effects of centrifugal acceleration, is presented for an arbitrarily loaded freight car negotiating an arbitrary spiral curve. Two types of equilibrium states are investigated: one with and one without car side bearing clearance. Using a case study as an example, the analysis predicts lighter and lighter loads for a particular wheel set as the 'roughest' part of the spiral curve is approached, just prior to derailment. Several possible causes for derailment, including lack of ballast and dynamic effects, are delineated. (Hannebauer)
