Effectiveness of measuring stress-free temperature in continuously welded rails by Rail Creep Method and Rail Stress Modules

摘要

Continuously welded rail track has two critical parameters that affect track stability, namely longitudinal rail stress and lateral resistance of the track structure. Maintaining the stress free temperature of rail plays an important role in managing of rail stress focussing on lateral track stability. Railway companies are focusing on finding an effective means of minimising longitudinal rail forces through management of Stress Free Temperature.
