摘要：
Rail construction including laterally adjacent frog sections with guard rails outwardly spaced to each side thereof by interposed liners. The components are interconnected by a transverse tightened bolt with vertical misalignment precluded by either nesting projections on adjacent abutting faces of the components or by a rigid, preformed sleeve press-fit within the bore receiving the bolt, the sleeve extending through the frog sections and at least partially through the liners.
