Human errors, as well as deliberate sabotage, pose a considerable danger to passengers riding on the modern railways and have created disastrous consequences. To protect civilians against both intentional and unintentional threats, rail transportation has become increasingly automated. Railway Safety, Reliability, and Security: Technologies and Systems Engineering provides engineering students and professionals with a collection of state-of-the-art methodological and technological notions to support the development and certification of Areal-time safety-criticalA railway control systems, as well as the protection of rail transportation infrastructures.A longitudinal current flowing under the train, when the train interconnects an insulated rail joint that has a broken side-bond. Obviously, jointless track circuits avoid the problem created by longitudinal current, but for many legacy signalling ... This would be identified by the false activation of track circuit relays from excessive longitudinal voltage or current at the ... frequency is 13.54MHz Ap 30ppm and the data uplink has a pulsecode modulation to provide a data rate of 9.6 kbits/s.
