An auto rack rail road freight car is provided for carrying low density, relatively high value, relatively fragile lading. The car has trucks that have multiple dampers in a four corner arrangement in the sideframes. The spring groups in the side frames are relatively soft, giving a low vertical bounce natural frequency. In an articulated embodiment, differentially placed ballast is mounted in a biased arrangement to load the coupler end trucks to encourage a dynamic response similar to the dynamic response of the internal trucks.
