Abstract
A railroad vehicle that moves a door to an airtight position and maintains air tightness of the door without increasing the size of a cylinder device; and a plug door for a railroad vehicle. When a door moves to a position, a piston extends in the vehicle width direction, a pressing member is contacts the inner surface of the door, and the door is moved toward a door frame. An auxiliary pressing device brings the piston into perpendicular contact with the inner surface of the door making it is possible to efficiently move and press the door without increasing the size of a cylinder device even when the door must be moved across a distance to arrive at an airtight position. The main pressing device is used to press the door toward the door frame.
