摘要:
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.
