The cab signal and rail navigation systems of a railway locomotive are combined to form a single integrated system capable of acting as an automatic train protection system. The train travels along a railway route equipped with a wayside signaling system that features a multiplicity ofwayside signal devices. Each wayside signal device provides to the cab signal system a cab signal inclusive of signal aspect information as to how the train should proceed along a particular segment of the railway route. When the train is traveling on a segment of track from which the cab signal is available, the cab signal system receives the cab signal via the AC track circuit disposed on the rails as the train approaches each wayside signal device. After filtering and decoding the electrical cab signal, the cab signal system communicates the deciphered signal aspect information to the rail navigation system. The rail navigation system determines whether signal aspect information should be available from the particular track segment the train is encountering and thus whether and how the brakes of the train will be operated thereon should the train engineer be required and fail to operate the brakes according to one or more braking profiles calculated by the system. The integrated system operates as an automatic train protection system whether the wayside signaling system provides cab signal coverage continuously or noncontinuously throughout the railway route.

[ I claim:] [1.] An integrated cab signal and rail navigation system for a rail vehicle travelling along a railway track featuring a multiplicity of wayside signal devices each of which situated along such railway track so as to communicate from a railway operating authority information including directions as to how such rail vehicle should proceed along a segment of such railway track generally corresponding thereto, said integrated system comprising:(a) a cab signal system to which said information is communicated from each of such wayside signal devices as such rail vehicle approaches thereto; and(b) a rail navigation system, to which said cab signal system is connected, for determining whether such segment that such rail vehicle is encountering is covered by one of such wayside signal devices and thus whether and how brakes of such rail vehicle will be operated thereon whether said rail navigation system receives or fails to receive said information while such rail vehicle is encountering such segment of such railway track.
