ABSTRACT:
An auto rack rail road freight car is provided for carrying low density, relatively high value, relatively fragile lading. The car has a relatively soft suspension and an empty vertical bounce natural frequency of less than 2.0 Hz. The car also has additional ballast to increase the dead sprung weight of the car relative to the weight of the lading. In the embodiments in which multi-unit articulated freight cars are employed, such as for auto rack rail cars, the ballast is located preferentially toward the coupler end trucks. The trucks for the railcar have an increased wheel base and damping located to provide a greater moment arm and bearing face to encourage a higher threshold for rail car hunting.
