ABSTRACT:
A rail joint includes an insulative base piece insertable between a rail base flange and a joint bar. The ends of the base piece project longitudinally beyond the respective ends of the joint bar to provide exposed terminal sections with an intermediate central section. Longitudinal migration of the base piece during travel over the rail joint is precluded by one or more end abutment members fixedly disposed relative the base piece and including an elevated inner abutment surface intermediate the central section and each terminal section and engaging the joint bar ends. The abutment members may comprise integral elevated tabs cut from the base piece or alternatively, separate members insertable through cut-out portions in the base piece terminal sections.
