Various methods are used to protect steel rails from excessive heat and cold. One primary measure to prevent steel rails from being damaged by excessive heat is the utilization of thermal expansion joints. These joints allow the rails to expand and contract as the temperature changes, preventing them from buckling or warping under extreme heat conditions. Additionally, a layer of paint or protective coatings that can endure high temperatures is often applied to steel rails, providing further protection against heat-related harm.
To shield steel rails from excessive cold, insulation materials are frequently employed. These materials are applied to the rail track in order to minimize the transfer of cold temperatures to the steel rails. Insulation aids in preventing the rails from freezing, which could result in cracks or deformations. In certain cases, heating systems are also installed beneath the rail tracks to melt ice and snow, preventing the formation of ice on the rails and ensuring safe operation.
In summary, a combination of thermal expansion joints, protective coatings, insulation materials, and heating systems are implemented to safeguard steel rails from the detrimental effects of excessive heat and cold. These measures help maintain the structural integrity of the rails, guaranteeing secure and dependable train transportation even in extreme temperature conditions.
