Abstract: This paper presented a modeling procedure for a DC traction power system (TPS) of electrified railway to study lightning transients with EMTP. The TPS included overhead lines, electric cables on the ground, masts and other associated components. The nonlinear ionization characteristic of earth resistance and the flashover characteristic of insulators were taken into account. These models were integrated to represent the whole TPS in open track, which was subject to a lightning stroke. Lightning transients on the TPS were simulated using EMTP. The maximum voltage on the cables installed in trough was estimated. The crest voltage under different stroke scenarios was presented to address the risk of a flashover on the cables in the paper. A sensitivity study of earth resistance for the masts is presented finally. The low earth resistance effectively reduces the surge voltage on the cables
