摘要： A concrete sleeper has an elongate metal insert having a T-slot containing a T-head of a retaining block which bears against a rail foot to retain rail gauge. The retaining block can be rotated by 180.degree. and slid along the T-slot to abut an edge of the foot of a rail, the T-slot being sufficiently long to allow adjustment of the rail on the sleeper. After rail position has been determined, the block location can be fixed by inserting grout into the T-slot. Alternatively, the T-slot can have abutment lugs which determine the block position, and thereby the rail position.

摘要： A fastener assembly for a railroad concrete sleeper wherein an insert is embedded in the concrete and extends across the sleeper, the insert having flanges which form between them a mouth of a T-slot over a wider space below the flanges and having surfaces which key it into the concrete, and a retaining block having a tail which bears upwardly against the undersurface of the flange which lies beneath a rail foot, and a head which bears downwardly on the upper surface of the other flange outboard of the rail foot, the head having an aperture extending through it in a direction also across the sleeper, and a bent rod type fastener is retained by the aperture and bears downwardly both on the rail foot and on the block head.
