Abstract
A track rail fastening system includes a direct fixation fastener assembly having a direct fixation fastener, and a laterally elongated support block. Fastener holes for receiving fastener-clamping fasteners, and fastener holes for receiving bracket-clamping fasteners, are formed in the support block. The respective sets of fastener holes are arranged in different anchor patterns. Fastener-clamping fasteners are received in one of the sets of fastener holes and claim direct fixation fastener to the support block. Bracket-clamping fasteners clamp a third-rail support bracket to the support block, and are received in one of the sets of fastener holes. The third-rail support bracket is cantilevered to the support block.
