10 10. TRAK-LOK STEEL SLEEPER SYSTEMS. Introduction Trak-Lok Steel Sleeper Systems are manufactured from Liberty OneSteel's rolled M sleeper sections and incorporates the Trak-Lok resilient fastening system that has been developed specifically for use with steel sleepers. Steel sleepers are support members that form part of the structure of the railway Track . The steel sleepers are embedded into ballast and provide support to the rails above. The steel sleepers tie the rails together maintaining gauge and rail position whilst resisting lateral and longitudinal movement of the rail . Recent developments in sleeper design have seen the introduction of the Deep End Spade (DES), offering improved lateral resistance to the sleeper system. The Trak-Lok 2 resilient clip secures the rail to the sleeper in conjunction with the appropriate Trak-Lok Lock In Shoulder.
