| Abstract | Canada’s climate has been warming at a rate that is approximately double the global average between 1948 and 2016. Climate change is impacting Canada more than the world as a whole, with climate models predicting further warming during all four seasons, ranging from an increase of a low of 1.8 ⁰C to a high of 6.3 ⁰C depending on the emissions trajectory (or representative concentration pathway). Canada’s extensive rail network of 46,000 km traverses from coast to coast through different climate zones. Without expansion joints to release thermal stress buildup due to changes in ambient temperature, continuously welded rail (CWR) is vulnerable to climate change. The increase in magnitude and frequency of extreme temperature events projected under future climate will induce additional longitudinal stress in the rail. This paper examines how the projected changes in climate will impact CWR, latest climate data and models, as well as propose a method, along with a case study to incorporate future climate scenarios into CWR thermal stress management practices for specific sites. |
