Abstract: Disclosed are a railway vehicle braking system and method. The railway vehicle braking system includes a braking command generating unit generating a braking command to stop a railway vehicle, a comparison unit determining whether the braking command has been changed, a delay unit delaying and outputting the braking command depending upon a determination result from the comparison unit, and a digital-to-analog converter converting the braking command, which has been delayed by the delay unit, into an analog signal and inputting the analog signal to an actuator.

Abstract: An apparatus and method for protecting a communication device of a railroad car is provided. The apparatus includes an antenna portion configured to include main antennas and an auxiliary antenna, a main receiver configured to check a magnitude of a received signal transferred through the main antennas of the antenna portion, an auxiliary receiver configured to check a magnitude of a received signal transferred through the auxiliary antenna of the antenna portion, and a controller configured to compare the magnitude of the signal received by the main receiver and the magnitude of the signal received by the auxiliary receiver, determine whether there is a jamming signal according to a comparison result, and take a preset countermeasure when it is determined that there is a jamming signal.
