Steel rails are manufactured by Liberty Primary Steel's Whyalla Steelworks in South Australia for use by the freight, mining and metropolitan rail networks. Both plain carbon and head hardened rails are available in a range of sizes and are produced in accordance with AS 1085.1–2002 Railway track material. Part 1 Steel rails.
Plain carbon is suitable for most network and light freight rail applications, while head-hardened rails exhibit greater durability and are suitable for heavy axle loads and tight-radius curves.
Steel sleepers are also available from Liberty that incorporate the company’s registered Trak-Lok resilient fastening system to secure the rail to the sleeper. Trak-Lok sleepers tie rails together to maintain gauge and rail position while resisting lateral and longitudinal movement of the rail. The Trak-Lok 2 resilient clip secures the rail to the sleeper in conjunction with the appropriate Trak-Lok 'Lock-n Shoulder'.
Among the benefits it offers is a lightweight design for ease of transport and handling, improved track stability and low maintenance costs.
