ABSTRACT:
A smooth junction is provided between aluminum conductor rails at the power collection surface by the provision of a wedge shaped insert the geometry of which corresponds to that of the gap between the rails. On expansion of the rails the insert is pushed partly out of the gap and on contraction is forced into the gap by a spring or springs thus always providing continuity on the power transfer surface.
