PROBLEM TO BE SOLVED: To provide a drive controller of a rail vehicle exhibiting significant energy saving effect by minimizing operation of a power conversion means under low temperature. SOLUTION: At the time of power up under low temperature, a processing for charging an electricity accumulation means through a means for converting AC power from an engine driven power generation means into DC power without operating a means for converting DC power from a power converting means into AC power, and a processing for absorbing power discharged from the electricity accumulation means by a load on the power generation means side through the means for converting AC power into DC power are repeated alternately.
