AS/RISSB 7643 : 2012

This document sets out the requirements for managing the stability of tracks for train operations in Australia. Track stability refers to the capacity of track to resist push out and buckling from compressive forces, curve pull-in and rail breaking from tension forces in the rails, due mainly to changes in rail temperature.The standard examines factors affecting track stability for the design and maintenance of Jointed, Long and Continuously Welded Rail. This standard covers rail networks classified as AS 7630. Tram tracks, cane railway and monorail networks are not included.Please note that this product is available in Excel format only. The Excel format allows users to more easily edit and comply with the standard, especially when working in the field. The decision to use Excel was based on much discussion and valuable feedback from customers of RISSB Australian Standards.
