Rail vehicles

Abstract

To provide a rail vehicle that improves strength against vertical loads while avoiding deterioration of manufacturability and increase in mass. [Solution] The rail vehicle consists of a roof structure that forms the top surface, a side structure that forms the sides, an end structure that forms the longitudinal end face of the side structure, a frame that forms the bottom surface, and a bogie that supports the frame. The side structure has a plurality of window openings arranged in the longitudinal direction of the rail vehicle and a winding section between the window openings. The diameter of the arc provided at the corner of the window opening located above the bogie is larger than the diameter of the arc provided at the corner of the window opening near the longitudinal center of the rail vehicle.
