Abstract In this paper, a chain network model based on multi-conductor transmission lines was briefly described, models of AT-fed traction power system are built by Matlab/Simulink, the simulation results of rail potential are given out, the impact of changing the traction network structures and parameters to rail potential such as transversal connection, rail-earth leakage conductance, AT leakage reactance and electric conductivity of integrated earthing has been studied, the results show that the effect of transversal connection to decrease rail potential is obvious , the effect of other measures is not obvious.
