Location

Description

The onset of hot weather brings with it the risk of track buckling if high rail temperatures are combined with deficiencies within the track system (i.e., incorrect rail stress, disturbed / deficient ballast, lateral alignment faults, incorrect rail joint gaps, etc.). Ideally, all such deficiencies should be eliminated before the hot weather season starts. As air temperatures increase during periods of hot weather, rail temperatures also increase. Metals expand and contract as the temperature changes. If a length of steel rail is rigidly clamped at both ends and then heated, the metal expands and is put under compression until the force becomes too great and exceeds the track systems lateral resistance forces.
