PROBLEM TO BE SOLVED: To solve the problems of a conventional operation of sidetracking a freight train having been houled by an electric locomotive into a cargo handling track, wherein the replacement of the electric locomotive with an internal combustion locomotive such as a diesel rolling stock spends excess time, labor and the like and ends in very poor working efficiency, and the inevitable allocation of the internal combustion locomotive even to a, freight station in an electrified railroad line for the purpose of moving the freight train into the cargo handling track hinders rationalization of freight station facilities. SOLUTION: Movable overhead line feeding facilities comprise a plurality of posts erected along a railroad line, arms attached to the upper portions of the posts for circumferential turning movement on the axes and for vertical movement along the axes, an overhead line suspended from the arms, and a controller for starting or stopping feeding the overhead line.
