Abstract
In an overhead electric traction system a simple and inexpensive mid-point anchor comprises a mast and, mounted on the upper part of the mast, a cantilever structure comprising a pair of rigid elongate members which lie in a common plane and extended transversely with respect to and lie spaced apart in a direction lengthwise of the track, and which at their ends nearer the track are connected to the mast by a third transversely extending elongate member inclined at an acute angle to the common plane. The ends of the members remote from the track are connected to opposite ends of a rigid bar which extends lengthwise of the track, which is pivotally connected to the mast about a vertical axis and which, at each of its end portions, is connected to the mast by a flexible tie. In the event of an unbalanced load on the catenary, pivotal movement of the cantilever structure about the vertical axis is prevented by one of the flexible ties and the out of balance load is transferred to the mast as a torsional load.
