T. PerryWestinghouse Brake and Signal CompanyToday, rail transport is faced with the ever-increasing demands for the higher speeds, closer headways and the strict adherence to established schedules, even under inclement weather conditions. Obviously these demands must be met, and in full compliance with safe train operation. To that end WABCO WESTINGHOUSE has developed automatic train control (ATC) systems. With an ATC system, wayside signals are in effect brought into the cab, thus informing the traindriver of the status of the signal blocks ahead and advising him of the maximum speed at which he is permitted to run. The cab signal controls are used in conjunction with a speed determining device to enforce the traindriver's obedience (overspeed protection) to the speed-limit conveyed by the cab signal. Consequently, any failure of the train driver to maintain his train speed results in an automatic brake application. |
