Title: DESIGN REFINEMENTS MAKE THE STEEL SLEEPER VIABLE
Abstract: Although steel is a relatively expensive material, careful investigation into the optimum rolled section for different loadings and duty cycles has produced a range of sleepers which are competitive with wood and concrete, bearing in mind the long life and high scrap value. Trials with 2500 heavy-duty steel sleepers on the Mount Newman iron ore line with 30-tonne axleloads have proved successful; two other types for main and secondary lines have been developed. One-piece polyethylene pads insulate the rail from sleeper and fastenings to permit the use of track circuits.
