In dampened railway car trucks wherein friction shoes are operatively carried in wedge-shaped pockets located at opposite sides of the bolster the invention provides for the retention of the friction shoes in a pocket in the bolster in the event the control springs become damaged or broken. The friction shoes are retained in the bolster pocket by the cooperation of a lip on the lower interior surface of the bolster pocket which engages the leading edge of the wedge-shaped friction shoe and the engagement of the rear vertical surface of the shoe and the adjacent vertical column of the side frame.
