摘要： Provided is a brake control system that can reduce use of a mechanical braking in a railway vehicle using an automatic train control (ATC). The present disclosure is a brake control system for a railway vehicle using an ATC. The brake control system includes: a main electric motor, a main conversion device, a brake controller, and an ATC device. The main electric motor generates a braking force by converting kinetic energy of a wheel of the railway vehicle to electrical energy. The main conversion device actuates the main electric motor. The brake controller outputs a braking signal to the main conversion device. The ATC device outputs a braking command to the brake controller based on the ATC. In addition, the ATC device outputs a preliminary braking signal for energizing the main electric motor prior to output of the braking command.

摘要： Provided are a railroad vehicle that makes it possible to maintain the air tightness of a door and a plug door for a railroad vehicle. A second rail is provided parallel to a first rail in the longitudinal direction of a vehicle body above the leading edge side (door side) of a plug rail. The second rail supports the leading edge side of the plug rail. As a result, both edges of the plug rail are supported by the first rail and the second rail. Dangling of the leading edge side of the plug rail is thus prevented even when the plug distance (the distance that the door moves in the vehicle body width direction) is long. In this way, it is possible to block the doorway without leaving a gap using the door and to maintain the air tightness of the door.
