ABSTRACT:
The invention provides a railway car with superior riding quality by improving the flexural rigidity of the car body structure while suppressing increase of body structure mass. A reinforcing plate7is attached to a roof construction1on the side facing an inner side of the car body at a longitudinal center portion of a railway car body structure10composed of a roof construction1, a side construction2, an underframe3and an end construction4. The range in which the reinforcing plate7is adhered in the longitudinal direction of the railway car body structure10is between two body bolsters6, and the range in which the plate7is adhered in the horizontal direction of the roof construction1is approximately half the length of the roof construction1in the horizontal direction. The thickness of the reinforcing plate7is increased gradually as the height of the roof construction1in the vertical direction increases. According to this arrangement, the deformation of the roof construction1at the longitudinal center portion of the railway car body structure10, which is excessive without the present arrangement, is suppressed, and the flexural rigidity of the railway car body structure10is effectively improved. In other words, the bending vibration of the railway car body in the vertical direction can be suppressed, and a superior riding quality is provided.
