Abstract: A train jolt determination system includes: a portable terminal capable of being held in a train and configured to acquire position information on the train, detect the acceleration of the train, and capture an image of the scene around the train; a storage section configured to associate the position information, acceleration information indicative of a detection result of the acceleration, and image information indicative of the scene and store the position information, the acceleration information, and the image information; and a jolt amount calculation section configured to calculate an amount of jolting of the body based on the acceleration information. In a case where the body is determined to have jolted based on the amount of jolting, position information associated with acceleration information used for the determination of jolting is supplemented with image information associated with the acceleration information, and a position where the body has jolted is estimated.

Abstract: A bodyshell of a railcar includes side outside plates, end bodyshells, and guiding plates. The side outside plate are located at both end portions of a carbody in a vehicle width direction. The end bodyshell includes an end outside plate and a corner post. The end outside plates are located at both end portions of the carbody in the longitudinal direction. The corner posts are located at four corners of the carbody. The corner post is joined to the adjacent end outside plate and the adjacent side outside plate. The guiding plate is provided at the side outside plate so as to cover the corner post from a vehicle exterior. The guiding plate includes an inclined portion and a joining portion. The inclined portion is provided in front of the corner post and inclined to the rear side toward the side outside plate.

Abstract: A bodyshell of a railcar includes side outside plates and end bodyshells. The side outside plates are respectively provided at both end portions of an underframe in a vehicle width direction. The end bodyshell includes end outside plates and corner posts. The end outside plates are respectively provided at front and rear end portions of the underframe. The corner posts are respectively provided at four corners of the underframe and are joined to the end outside plates and the side outside plates. Moreover, the corner post includes a side plate joining portion. The side plate joining portion overlaps a front end portion of the side outside plates from an outer side in the vehicle width direction and is joined to the side outside plate.

Abstract: A railcar that includes an underframe, a front surface frame located at a front surface portion of a carbody and having a lower end portion coupled to the underframe, and a buffer member coupled to the front surface frame and extending toward a vehicle interior side. Then, the buffer member is provided at a position higher than the underframe.

Abstract: A thawing device for railway track points is constituted by connecting a heating coil (1a) wound around a floor plate (2) for heating the floor plate (2) by induction to an inverter device (5) for supplying high-frequency current to the heating coil (1a), via a connection cable (4); and providing a protection against magnetism (9, 10a-10c, 11a-11c , 12a, 12b) about the periphery of the heating coil (1a) and the connection cable (4).

Abstract: Low aerodynamic noise type current collection equipment is provided for reducing variations in aerodynamic force applied to a current collector during train operation. A central region (2a) of a current collector (1) having a collector head (2) with a top surface in which a contact strip (3) is embedded is rectangular in cross-section, and each side region is shaped convex in cross-section in the front and rear directions, with e.g. an elliptical shape. The rectangular shape has characteristics such that the magnitude of the aerodynamic lift force would be kept substantially constant even if the inclination angle against the aerial flow would be changed.
