Action description

V/Line advised that the network standard for the inspection and assessment of lateral stability has been amended to include the requirement to measure and correct Stress Free Temperature (SFT) prior to the onset of the summer period (1 November to 31 March), with additional controls for any loss of rail stress detected during the summer period. The Technical Maintenance Plan has been amended to ensure creep measurements are completed 3 weeks prior to the summer season, to permit sufficient time for creep condition assessment and stress free temperature testing and correction.
