Steel rails are protected against excessive heat by using various methods such as employing heat-resistant materials, implementing cooling systems, and ensuring proper ventilation.
Steel rails are protected against excessive heat through a process called thermal expansion. This involves allowing room for the steel rails to expand and contract as temperatures change, preventing them from warping or buckling under high heat conditions. Additionally, steel rails are often coated with a protective layer, such as a heat-resistant paint or a layer of concrete, which helps to further insulate them against excessive heat.
Steel rails are protected against excessive heat through a process called heat treatment. This involves subjecting the steel rails to controlled heating and cooling cycles to enhance their strength, hardness, and resistance to heat-related damage. Additionally, railways use various cooling techniques, such as water spraying systems, to prevent the rails from reaching critical temperatures during extreme heat conditions.
