Ride characteristics of three different truck spring arrangements applied to multi-level auto rack equipped 89 ft. (27.1 m) flat cars were measured. Spring arrangements consisted of a group designed to carry the full AAR axle capacity, a reduced capacity group designed for the actual weight carried, and a hydraulically damped spring group. Data was reduced using a spectrum analyzer to produce spectral density plots.
