Abstract: A pipe clamp wedge is disclosed that can be used with an existing pipe clamp anchor to secure a brake line pipe to a rail car. The wedge has a cradle portion having a concave side receiving the pipe, and a convex wedge side opposite the concave side. The cradle portion has a height increasing in a longitudinal direction, and a pair of opposed channels on lateral sides of the wedge are adapted to receive tabs on the pipe anchor. A pair of tabs on the wedge extends in the opposite direction from the tabs on the pipe anchor on either side of the cradle portion. Thus, the wedge can be slid onto the anchor, tightening around the pipe as the wedge moves in the longitudinal direction onto the anchor, and the wedge is dimensioned so that when the wedge cannot move further, the tabs on the wedge extend beyond the pipe anchor and may be bent up (toward the railcar) to secure the wedge. The parts of the combination are adapted so that sliding the pipe onto the anchor and bending the tabs may be done with a hammer.

Abstract: A railway car truck incorporating an interconnection between the side frame and bearing adapter is characterized by a low lateral spring constant relative to the longitudinal spring constant. The interconnection provides a proportional restoring force with minimal internal friction and hysteresis. In embodiments, the interconnection comprises compressed elastomeric members positioned between the thrust lug of the side frame and the bearing adapter in the longitudinal direction and a low friction interface between the roof of the pedestal jaw and the top of the bearing adapter.

Abstract: A trolley hanger for supporting brake hose connections between rail cars which hangs securely on a trolley rod, and preferably is directly connected to an intermediate hose flange, a train line support casting flange, or trolley pipe flange, prevents lateral and rotational movement of a brake hose connection, thereby reducing unwanted brake hose uncoupling.
