A system and method for reducing the shop time 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.
