ABSTRACT OF THE DISCLOSURE This disclosure concerns a spring system between the body of a railroad car and the wheel supporting truck. The spring system includes a coil spring for-absorbing vertical forces and includes a rubber layer spring for absorbing lateral forces, the latter resulting from lateral impact and movement of the railway car along curves in the track. The last mentioned rubber spring is coaxial with and placed inside the first-mentioned coil spring, thereby minimizing the vertical height of the spring system. A pair of spring washers extends laterally between the car body and the truck. The spring washers are held apart by the coil spring. The rubber spring is divided be- tween a first section above the upper spring washer and the undercarriage o e the car and a second section beneath the lower spring washer and the frame of the truck. The spring washers have a plurality of troughs for receiving a plurality o-f sets of springs. For rigidifying purposes, the spring washers on opposite sides of the truck are held together by rigidifying bars.
