A locomotive (10) is operable in two or more distinct configurations, with the change in configuration being response to a configuration input signal (35). A locomotive configuration is represented by the set of end use device control signals (13) that are generated by the locomotive control systems (22) in response to the respective set of operational input values (27). For a given set of operational input values, a first set of end use device control signals is generated when a configuration input has a first value, and a second set of end use device control signals is generated when a configuration input has a second value. The configuration input variable is responsive to an emission profile associated with the locomotive location. A value of a locomotive emission parameter corresponding to the emission profile is monitored and saved in a storage device (e.g., 104).

What is claimed is: 1. A system for monitoring and controlling locomotive engine emissions comprising: a location determination unit for determining a geographic location of a locomotive; memory for storing a plurality of predetermined engine emission profiles, one profile for each of a plurality of geographic locations; a processor in communication with the memory for accessing the engine emission profile for the determined location of the locomotive and generating an engine control command responsive to respective engine emission profile and engine operating parameters; a control unit on board the locomotive controlling an operation of the locomotive responsive to the engine control command to limit the production of engine emissions to the corresponding emission profile; a monitor unit monitoring values of an emission parameter of the locomotive indicative of the emissions produced by the engine; and memory storing the values of the emission parameter of the locomotive and at least one of the time and the location of the locomotive when the engine emission was monitored. 2. The system of claim 1, further comprising: a communications interface for transmitting the values of the emission parameter off-board the locomotive; and a central monitoring system, remote from the locomotive, for receiving the values of the emission parameter transmitted via the communications interface. 3. The system of claim 1, wherein the monitor unit comprises a sensor selected from the group consisting of an engine inlet air temperature sensor, a fuel injection timing sensor, a fuel injection pressure sensor, and a sensor sensing engine exhaust characteristics. 4. The system of claim 1, wherein the monitor unit comprises: an engine power sensor; an engine speed sensor; and a fuel usage sensor. 5. A method of monitoring locomotive engine emissions: determining a location of a locomotive; determining an emission profile of the locomotive as a function of the location of the locomotive; controlling an operation of the locomotive in response to the emission profile; monitoring values of an emission parameter of the locomotive corresponding to the emissions profile; and storing the values of the emission parameter. 6. The method of claim 5, further comprising providing the values of the emission parameter to a central monitoring system off-board the locomotive. 7. The method of claim 6, further comprising determining, at the central monitoring system, compliance with the emission profile based on the values of the emission parameter. 8. The method of claim 7, further comprising allocating, at the central monitoring system, emission credits for values of the emission parameter less than a minimum value required by the emission profile. 9. A method of managing operation of a locomotive that moves between at least two operating areas, the locomotive having at least two emission profiles of operation, the locomotive traveling along a path comprised of at least two operating areas, each operating area having at least one emission profile associated therewith, with the emission profile of one operating area being different from that of a second area, the method comprising: monitoring a location of the locomotive to determine its operating area; controlling an operation of the locomotive as a function of the determined operation area and an associated emission profile, the emissions profile including a restriction on an operation of the locomotive based on its position relative to an emission control area; and storing values of an emission parameter of the locomotive associated with operation of the locomotive in the operating area. 10. The method of claim 9, further comprising: storing the values of the emission parameter on-board the locomotive; and periodically downloading the stored emission values. 11. The method of claim 9, further comprising calculating a rate of engine emission discharge. 12. The method of claim 9, further comprising calculating an amount of an engine emission discharge during a time the locomotive is located in a predetermined geographic area. 13. The method of claim 9, wherein the locomotive is one of a fleet of similar locomotives, the method further comprising calculating an amount of engine emission discharge for each of the locomotives of the fleet located in a predetermined area during a selected interval of time. 14. The method of claim 13, further comprising controlling the operation of each of the locomotives entering, leaving, and operating in a predetermined operating area so that an amount of engine emission discharge from each of the locomotives does not exceed a predetermined limit. 15. The method of claim 9, wherein monitoring comprises a locomotive operator identifying movement of the locomotive from the one operating area to the second area. 16. The method of claim 15, wherein controlling comprises the operator controlling the operation of the locomotive responsive to the movement of the locomotive from the one operating area to the second area. 17. Computer readable media containing program instructions for monitoring locomotive engine emissions, the computer readable media comprising: a computer program code for determining a location of a locomotive; a computer program code for determining an emission profile of the locomotive as a function of the location of the locomotive; a computer program code for controlling an operation of the locomotive in response to the emission profile; a computer program code for monitoring values of an emission parameter of the locomotive corresponding to the emissions profile; and a computer program code for storing the values of the emission parameter.
