本标准规定了澳大利亚列车运行轨道稳定性管理的要求。 轨道稳定性指的是轨道抵抗主要由于轨道温度变化而产生的压缩力、曲线拉入力和轨道张力导致的钢轨断裂的能力。 本标准检查了影响连接、长钢轨和连续焊接钢轨设计和维护的轨道稳定性的因素。 本标准涵盖分类为7630的铁路网。 不包括有轨电车轨道、甘蔗铁路和单轨网络。

This Standard 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. This Standard examines factors affecting track stability for the design and maintenance of jointed, long and continuously welded rail. This Standard covers rail networks classified in AS 7630. Tram tracks, cane railway and monorail networks are not included.
