ABSTRACT:
A composite minimum-joint electrified rail is constructed by combining a non-conductive support rail divided into easily installed segments with a continuous conductive rail that mounts on the support rail and spans any number of support rail segments. The conductive rail may be attached to the non-conductive rail by a tongue and groove arrangement. Multiple conductive rails or strips may be attached to different portions of the same support rail. In addition spring clips are shown for attaching the support rail to railroad ties or roadbed, and fish plates are shown for attaching abutted support rails.
