After an analysis on the current collection by train operated in urban rail transition system and the relevant current carrying capcity demand on conductor rail in overhead contact system, it is recommended that a periodical cyclic loaded current wave form for rating and test verification of the current carrying capacity of conductor rail be adopted. Heat run tests both under continuous loaded and periodical cyclic loaded current for conductor rail popularly used in existing overhead contact line system are conducted and the results are compared and analysed .
