    Patent number: 6431462
    Abstract: A concrete gauge panel spans the gap between two parallel railroad tracks. Two concrete field panels lead from the roadway surface to the railroad tracks, one panel on each side of the railroad tracks. A spacer sits between the concrete of the concrete field and gauge panels and the railroad tracks. The spacer is affixed to the panels in a way that allows the spacer to be removed and replaced without replacing the entire panel.
