Abstract
A rail mount secures a longitudinally extending rail having a foot to a sleeper of a track system. The mount has a rail base plate on the sleeper underneath the rail foot and unitarily formed with a pair of upwardly projecting holders transversely flanking the rail and each formed with at least one vertically throughgoing bore. Respective anchor bolts engaged vertically downward through the bores have heads bearing downward at least indirectly on the respective holders and are seated in the sleeper to hold the base plate down on the sleeper. Respective elastically deformable clips fitted to the holders below the respective anchor-bolt heads bear upwardly on the holders and downwardly on the rail foot to press the rail downwardly toward the sleeper.
