RAILWAY CAR TRUCK WITH FRICTION DAMPING A device is provided for addition to a three piece railway freight truck to prevent vertical over travel of the bolster (13) and absorb inertia energy of the bolster (13) before it impacts the sideframe (2, 13) or brake equipment. Two variations of this device have a gap which prevents the device from being engaged under normal operating conditions. The device utilizes an energy absorbing elastomer material mounted between the top of the bolster end (14, 15) and the bottom of the sideframe top center compression member.
