ABSTRACT:
A sliding joint of the type designed to permit expansion and contraction between adjoining ends of rail sections in a single or double track system is characterized by having a rail point defining an extension of one adjoining end which is both lengthened and reinforced along the area adjacent to its juncture with the one adjoining end to more effectively absorb and distribute stresses imparted under wheel loading. A limit stop for the curved end of the rail section is mounted on the base of the joint ahead of the juncture of the rail point with the one adjoining end of the rail so as to further alleviate stresses imparted by the curved rail to the rail point when the curved rail undergoes maximum expansion.
