Abstract Research purposes: All parallel supply with parallel branch connecting the upward and downward catenaries in the dual electrified railway will made the current distribution more balanced and could promote the power supply quality roundly，which is specially adapted to the electrified railways with mono － directional traction load in mountain areas． Currently the parallel branch was set in the middle of the supply arm，but the reason could not be found． In this paper the load capacity of traction network with all parallel supply mode is calculated and the best position of the parallel branch is also analyzed．
Research conclusions: ( 1) All parallel supply mode can reduce the demand of load capacity efficaciously． ( 2) The best effect arises when the parallel branch is set at the front one － quarter of the supply arm． ( 3) The current flowing in the parallel branch always keep at 25% approximately． ( 4) The best position of the AT post is also at the front one － quarter of the supply arm．

Key words： traction network all parallel supply current distribution load capacity Parallel Position
