Review of factors affecting stress-free temperature in the continuous welded rail track

Railways have a significant role to play in sustainable transportation. Rail travel is currently the only mode of rapid, large-scale, long-distance transport for both freight and passengers that offers zero carbon dioxide emissions at point use. However, our railway infrastructure needs be more robust resilient combined effects climate change, traffic growth increases vehicle loads speed. buckling increasing concern as environmental temperatures rise loads, speed intensity use increase. A key indicator control propensity track stress-free temperature rails. determining actual given section challenging. Knowledge factors affecting will help identification vulnerable sections development an appropriate maintenance regime. This paper reviews discusses ballasted with continuous welded rails (CWR).
