ABSTRACT:
A miter rail system for spanning a railroad track joint including a fixed rail, a lift rail and a rider rail connected to the fixed rail. The rider rail has an upper surface including a central portion defined by an arc of constant radius and opposite end portions. The apex of the central portion is greater in height than the height of the fixed rail and lift rail, and the height of the opposite end portions at opposed end faces of the rider rail is sufficiently low to avoid contact by a rolling stock wheel.
