The test equipment is supported at the end of atelescopic horizontal arm, which may be closed and swungout of the way parallel to the track when not in use. Thetest equipment is coupled up to the train and signal lines atthe rear end of the tender by means of hose and standardcoupling, from which pipe lines lead along the side of theinspection pit and up through the base of the crane. Fromthe upper end of these pipes hose connections of sufficient. s J fill J
