Buckling of rails
WebBuckled Rail Buckled Rail On warm days, rails in direct sunshine can be as much as 20 degrees centigrade above air temperature. As rails are made out of steel, they expand … WebThe critical buckling load is given by Modern rail sections have a large second moment of area I, so this helps to stop buckling. However, the rail is very long (large L ), so if the rail is not prevented from moving sideways, it will buckle very easily.
