[Superseded]Railway track material, Part 1: Steel rails
Specifies performance requirements for as-rolled and head-hardened steel rail, covering track compatibility, service life, material integrity, connection, maintenance and handling. Asymmetric switch rails and elevated guardrails are also covered. Appendices five deemed to comply solutions for profiles, tolerances, chemical composition, mechanical properties and specify test methods for inclusions and surface finish. Guidance to purchasers, information on compliance and on residual stresses in rail is also given in appendices.
