Classification: CPC B  G | IPC G

Claim 0:
1. A system for performing root cause analysis of a positive train control (PTC) enforcement event, comprising:
a memory having a database with system component logs for determining a root cause; and
a networked computer processor operably coupled to the memory and capable of executing machine-readable instructions to perform program steps, the program steps comprising:
determining, based on one or more conditions, to generate a PTC enforcement event in response to identifying one or more potential risks to a vehicle;
initiating, based on the PTC enforcement event, a change in a speed of the vehicle to respond to the one or more potential risks;
receiving extracted data, wherein receiving the extracted data includes:
receiving an indication that the PTC enforcement event has occurred, the indication including a set of data related to the PTC enforcement event;
clearing the PTC enforcement event for processing by conducting a health scan of the system to determine that the set of data related to the PTC enforcement event is reliable to perform analysis of the PTC enforcement event;
selecting an extraction model based on a determination that the selected extraction model will yield a set of data points required for event analysis;
applying the extraction model to extract data for event analysis; and
receiving the extracted data, wherein the extracted data includes data associated with events related to the PTC enforcement event;

executing a first analysis model using the extracted data to generate a first result and assigning a first unique ID to the first result;
if a defect is detected in the first result based on the first analysis model, classifying the defect as a root cause of the PTC enforcement event;
if a defect is not detected in the first result based on the first analysis model, executing a second analysis model using the extracted data to generate a second result, assigning a second unique ID to the second result, and comparing the first result with the second result to determine a most accurate result as the root cause of the PTC enforcement event, wherein comparing the first result with the second result includes comparing an accuracy of the first result to an accuracy of the second result to determine the most accurate result as the root cause of the PTC enforcement event;
generating a report to indicate the root cause of the PTC enforcement event; and
storing the first result, the first unique ID, the second result, and the second unique ID.
