Abstract: A hybrid support bracket for supporting a flexible end hose of a railcar air brake hose assembly is described. The bracket has a free end of a predetermined length and a train line support unit is displaceable along the displaceable free end. The train line support union has a connector which connects an end of the flexible end hose to the brake hose assembly. The hybrid bracket is secured to the yoke of a coupler and is displaceable therewith. The displaceable free end and train line support union permit relative displacement between the hybrid bracket and the hose support to compensate for the slack of the coupler due to wear.

Abstract: A test flange is used for an air brake piping system for railroad cars. The flange fits between an end flange of the brake cylinder pipe and the housing of the valve to which it is normally connected. The test flange includes a through aperture that aligns with the pipe end and the port in the valve housing and a test port that carries a quick disconnect valve in a lug with a distinct offset from the symmetrical centre line of the test flange. An internal passage in the test flange leads from the aperture to the test port.
