A gauge plate insulator includes a body having a first side and a second side positioned opposite the second, with the first side of the body defining a planar surface, and the body defining a first opening and a second opening, and a leg extending from the second side of the body and configured to be positioned between first and second gauge plate members. The leg is positioned between the first and second openings of the body, with the body and leg formed integrally from a fiber-reinforced polymer.

A center support sleeve for a bonded rail joint bar that includes a body having a head portion, a web portion, and a base portion. The head portion depends from the web portion, which depends from the base portion. The head portion and the base portion are bent in the same direction thereby defining a recess area therebetween. The web portion of the body also defines a plurality of holes.

A rail joint bar, comprising: a first side and a second side; wherein the first side has a longitudinal axis and a first outer surface curved convexly or concavely along the longitudinal axis and wherein the first outer surface defines a rounded shape conforming to and fitting within a concavely or convexly curved channel of a side of a curved railroad rail joint, wherein the concavely or convexly curved channel is defined by a web, a head and a foot of the railroad rail joint; and wherein the second side has a second outer surface that has a flat surface following the same curvature of the first side.

A bonded, electrically insulated rail joint (IRJ) assembly for railways or subways is realized by machining two standard switch rails and subsequently coupling them by use of a lower bolted cover plate.
