    摘要： A railcar that allows a first end beam to move toward a second end beam when an intended load is input is provided. A railcar includes a fuse member that couples a first end beam to a second end beam along a car longitudinal direction, and the fuse member buckles when a load received in collision exceeds a predetermined value to allow the first end beam to move toward the second end beam, thus ensuring reduction of variation of the load that allows the first end beam to move toward the second end beam. Consequently, when the intended load is input, the first end beam is allowed to move toward the second end beam.

    摘要： According to a railcar, a low-floor underframe includes side beams to which side bodyshells are coupled, a high-floor underframe includes a center sill disposed to extend in a car longitudinal direction at a center in a car width direction and a body bolster coupled to this center sill and to be an installation portion of a bogie, and the body bolster is coupled to the side beam by a coupling member. Thus, the car end compression load input to the high-floor underframe can be directly transmitted from the center sill and the body bolster to the side beams via the coupling member. This can disperse the car end compression load on the side bodyshells to ensure the car strength against the car end compression load.

    摘要： A railroad vehicle fire-resistant floor structure with improved fire resistance against underfloor fires includes a mounting part for installing underfloor equipment on the lower surface of an underframe, and a fire-resistant member. The fire-resistant member is a fire-resistant coating applied to the lower surface of the underframe. The fire-resistant coating is preferably a foamable fire-resistant coating. A cover that covers an exposed portion exposed from the fire-resistant coating (foamable fire-resistant coating) is attached to the mounting part. The underfloor equipment is installed at the mounting part with a closing plate sandwiched therebetween.

    摘要： According to a railcar, a fuse member that couples a first end beam to a second end beam along a car longitudinal direction is formed as a channel material with an approximately U-shaped cross-section, including a web disposed to extend along the car longitudinal direction and a pair of flanges disposed upright from both end portions of this web. Accordingly, when a load received in collision exceeds a predetermined value, the fuse member buckles to allow the first end beam to move toward the second end beam to ensure reducing variation of the load that allows the first end beam to move toward the second end beam. Consequently, when the intended load is input, the first end beam is allowed to move toward the second end beam.

    摘要： 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 the position as indicated by the two-dot/dash line in FIG. 1, 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 as indicated in FIGS. 5(a)-5(b) is used to press the door toward the door frame.
