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.

Curved insulated rail joint bar and methods for making same

An end post () for a rail joint assembly comprising: a top portion () consisting essentially of a first electrically insulating material comprising a fiber reinforced polymer material and having a profile substantially identical to cross-sectional shapes of rail head sections of first and second rails of the rail joint assembly; a base () having a profile substantially identical to cross-sectional shapes of rail base sections of first and second rails of the rail joint assembly; and a stem () disposed between the top portion () and the base (); wherein the stem () and the base () consist essentially of a second electrically insulating material comprising a polymer material.

Composite rail joint end post

An end post for a rail joint assembly comprising: a top portion having a profile substantially identical to cross-sectional shapes of rail head sections of first and second rails of the rail joint assembly; a base; and a stem disposed between the top portion and the base; wherein one or more of the top portion, base and stem comprise a plurality of pieces of a first electrically insulating material disposed on or in a second electrically insulating material. The plurality of pieces are preferably spaced apart and may have a substantially disc-shape or a substantially cylindrical-shape, and are preferably made from a ceramic material such as zirconium dioxide, aluminum oxide or silicon nitride, where the second electrically insulating material comprises a polymeric material, such as polyurethane.
