Extreme weather conditions present unique challenges to the mechanical behavior of elastic materials under railway dynamic loading. For designers, operators, and maintenance teams in railway projects, understanding how temperature variations impact material performance is crucial throughout a project’s lifecycle. Deviations from specified temperature limits can compromise system integrity, potentially leading to failures and catastrophic events like rail vehicle derailments or track shutdowns. This issue has become increasingly relevant due to climate change, which exposes railway tracks to temperature variations beyond their original design specifications. In this literature review, we explore the behavior of elastic track components, focusing on materials such as polyurethane on extreme weather conditions. Our goal is to examine how the unique properties of these materials affect the overall track structure and propose strategies to mitigate issues arising from unusual temperatures like extreme cold conditions. Our findings show that changing of the material composition can enhance safety margins, ensuring that railway track systems maintain performance and reliability even in the harshest environments.
