ABSTRACT:
The specification describes an improved railroad track expansion joint which is comprised of a pair of longitudinally aligned elongated joint members interconnected with one another by means of a dovetail joint formed along abutting faces which extend at an acute angle to the members. The other ends of the joint members are connected to conventional rails and any expansion and contraction of the rails will cause the members to slide relative one another along the abutting face.
