Systems and methods for independent checking and healing of positive train control systems

A method by a computing system for monitoring a positive train control (PTC) system, the method comprising:

• receiving a plurality of first mandatory directives from a train authority computing system;
• receiving a plurality of second mandatory directives from a train bulletin computing system;
• storing the plurality of first mandatory directives and the plurality of second mandatory directives as issued mandatory directives in a database;
• receiving a plurality of onboard mandatory directives from a PTC back-office computing system, the plurality of onboard mandatory directives mirroring mandatory directives stored on a locomotive;
• storing the onboard mandatory directives in the database;
• comparing the issued mandatory directives with the onboard mandatory directives in order to identify any mismatches between the issued mandatory directives and the onboard mandatory directives;
• and
• electronically communicating across a communications network, when a mismatch between the issued mandatory directives and the onboard mandatory directives is identified, one or more instructions for the PTC back-office computing system to remediate the mismatch between the issued mandatory directives and the onboard mandatory directives.

One or more computer-readable non-transitory storage media embodying instructions that, when executed by a processor, cause the processor to perform operations comprising:

• receiving a plurality of mandatory directives from a computing system;
• storing the plurality of mandatory directives as issued mandatory directives in a database;
• receiving a plurality of onboard mandatory directives from a positive train control (PTC) back-office computing system, the plurality of onboard mandatory directives mirroring mandatory directives stored on a locomotive;
• storing the onboard mandatory directives in the database;
• comparing the issued mandatory directives with the onboard mandatory directives in order to identify any mismatches between the issued mandatory directives and the onboard mandatory directives;
• and
• electronically communicating across a communications network, when a mismatch between the issued mandatory directives and the onboard mandatory directives is identified, one or more instructions for the PTC back-office computing system to remediate the mismatch between the issued mandatory directives and the onboard mandatory directives.
