A method and apparatus for chronologically combining fault data, repair data, and operational parameters for a railroad locomotive. Generally, this data is collected and stored in separate databases. The present invention teaches combining the data so that an ordered analysis reflecting the timing of faults, repairs, and operational information can be carried out to determine the root causes of the faults.

1. A method for analyzing faults from a locomotive, said method comprising:(a) receiving fault data from a fault database off-board the locomotive, wherein the fault database comprises faults experienced by the locomotive, including information as to when the fault occurred;(b) receiving operating parameter data from the locomotive, including information as to when the operating parameter data was collected;(c) receiving repair data from a repair database off-board the locomotive, wherein the repair database comprises repairs performed on the locomotive, including information as to when the repair was performed; and(d) combining the fault data, the repair data, and the operating parameter data in chronological sequence, to analyze locomotive faults. 2. An article of manufacture comprising a computer program product comprising a computer-usable medium having a computer-readable code therein for analyzing faults from a locomotive using time-tagged data from a plurality of sources, said article of manufacture comprising:(a) a computer readable program code module for receiving fault data representing the faults experienced by the locomotive, including information as to when the fault occurred;(b) a computer readable program code module for receiving data representing the operational aspects of the locomotive, including information as to when the operational data was collected;(c) a computer readable program code module for receiving off-locomotive data selected from the group comprising repair data describing repairs performed on the locomotive including information as to when the repair was performed, maintenance data describing maintenance performed on the locomotive including information as to when the maintenance was performed, and past fault log data describing past faults occurring on the locomotive including information as to when the past fault occurred; and(d) a computer-readable program code module for combining the fault data, the operational data and the off-locomotive data in chronological sequence for use in analyzing faults from the locomotive. 3. A method for analyzing faults that occur in railroad locomotive operation using time-tagged data from a plurality of sources, said method comprising:monitoring operation of a railroad locomotive for faults and operational conditions of the locomotive;transmitting the data indicative of the faults and operational conditions from onboard the locomotive to an off-board location via wireless communications;accessing off-board data from the group comprising locomotive repair data, maintenance data and past fault log data for the locomotive stored in one or more historical data bases off-board of the locomotive;combining the onboard data and the off-board data in chronological sequence; andgenerating a report including the combined data for use in identifying locomotive operation faults and their causes. 4. The method of claim 3 wherein the step of accessing further comprises accessing off-board data from the group comprising locomotive repair data, maintenance data, past fault log data and operational statistics data for the locomotive stored in one or more historical data bases off-board of the locomotive. 5. The method of claim 3 wherein the off-board location comprises a remote monitoring and diagnostic center. 6. The method of claim 3 wherein the generating step further comprises generating a report including the combined data for use in identifying locomotive repair and maintenance actions. 7. The method of claim 3 wherein the step of monitoring further comprises monitoring operation of a railroad locomotive for faults and for operational conditions of the locomotive occurring at or near the time of the faults. 8. The method of claim wherein the step of generating further comprises generating a report including the combined data for use in identifying potential fault conditions on the locomotive. 9. A method for analyzing the effectiveness of repairs made to a railroad l ocomotive using time-tagged data from a plurality of sources, said method comprising:monitoring operation of a railroad locomotive for locomotive operational conditions occurring both before and after the time of a repair to the locomotive;transmitting the data indicative of the operational conditions from onboard the locomotive to an off-board location via wireless communications,accessing off-board data from the group comprising locomotive repair data, maintenance data and past fault log data for the locomotive stored in one or more historical data bases off-board of the locomotive;combining the onboard data and off-board data in chronological sequence; andgenerating a report of the combined data for use in evaluating the effectiveness of the repair.
