1. A method of reducing the shop time of locomotives at a locomotive maintenance facility comprising:
- providing data gathering systems onboard a locomotive and a computer at a remote locomotive maintenance facility, said computer having a historical data base of locomotive system data on a plurality of similar locomotives, said locomotive system data being selected from the group consisting of ambient air temperature, train notch, total track and force power, total voltage, total amps, software versions, engine RPM, engine temperature, crankcase pressure, dynamic braking, battery voltage, and voltage and amperage for all auxiliary motors;
obtaining onboard locomotive systems data with said onboard data gathering systems during operation of said locomotive, prior to arrival of said locomotive at said locomotive maintenance facility for scheduled maintenance;
transmitting said onboard systems data via wireless communications to said maintenance facility prior to arrival of said locomotive at said maintenance facility;
operating said computer at said maintenance facility, prior to arrival of said locomotive at said maintenance facility, to compare said onboard system data with said historical data base to determine whether any of said onboard system data is out of a predetermined range or is within said predetermined range, but exhibiting a trend toward being out of said range;
operating said computer at said maintenance facility, prior to arrival of said locomotive at said maintenance facility, to assign at least one fault code corresponding to at least one system fault based on said onboard systems data being either out of said range or exhibiting a trend toward being out of said range, said at least one fault code being selected from the group consisting of overcurrents, flashovers, crankcase overtemperatures, crankcase overpressures, communication failures, electrical around failures, air conditioner converter failures, propulsion system faults, auxiliary system faults, propulsion motor faults, auxiliary motor faults, auxiliary system charging faults, engine cooling system faults, oil system faults, control wiring faults, and microelectronics faults; and
operating said computer at said maintenance facility, prior to arrival of said locomotive at said maintenance facility, to determine any maintenance and repair operations to be performed when said inbound locomotive arrives at said maintenance facility, in response to said at least one fault code.

Abstract
A system and method for reducing the shop lime of a vehicle, e.g., a locomotive, at a maintenance facility by obtaining onboard systems parameter data during a period when the vehicle is inbound to the maintenance facility for required periodic scheduled maintenance, and by determining, at the maintenance facility and prior to arrival of the vehicle at the maintenance facility, from the data received from the inbound vehicle, whether any of the data is out of a predetermined range or is trending to be out of range.
