PROBLEM TO BE SOLVED: To provide an electric power conversion system having a stack structure which is small and formed in consideration of improvement of cooling performance, and to provide a railway vehicle.SOLUTION: An electric power conversion system includes: a plurality of semiconductor modules including a plurality of switching elements therein; a heat receiving block having the plurality of semiconductor modules on one surface; cooling fins provided on the other surface of the heat receiving block; filter capacitors electrically connected to the semiconductor modules; and gate drive devices which send control signals to the switching elements. A longitudinal direction of each semiconductor module is oriented in a direction orthogonal to cooling air passing through spaces between the cooling fins.SELECTED DRAWING: Figure 1
