A symmetrical multi-unit railroad freight car, such as a 3-pack railroad intermo dal well car, has body units that are connected symmetrically. The body units have a symmetrical arrangement of end trucks and shared trucks. The end trucks are 70 Ton Trucks. The shared trucks are 125 Ton trucks. The trucks have passive steering using geometric rocker stiffiiesses. The rockers in the end trucks have a smaller radius of curvature than the rockers in the shared trucks. The spring groups in the shared trucks are stiffer than the spring groups in the end trucks. The spring groups in the end trucks have a different proportion of damping when empty, a shorter live load range of travel, and greater reserve travel than the shared trucks. The end trucks and the shared trucks have four-cornered damper groups that have the same sized damper wedges. The damper wedges have non-metallic wear pads.
