In India most common means of transportation is railway. Most of the railway line is electrified, which increases the demand for electricity. Indian Rail uses only two phases from three-phase electric power supply to fed locomotive. Arrivals of locomotive at substation are dynamic load. Due to this voltage drop occur at OHE and three phase supply line also, result of this is inefficient operation of motor in loco. Due to excessive load the circuit breakers may trip without any fault on line. To avoid this problem many research is going on, some are given in this paper. This paper summarize the latest trends in the railway traction system .AC traction as an achievement in the power electronics after 1980’s contributes to the present efficient high speed mass transportation service.
