The method of claim 1, wherein the fuel market information includes, for at least one of the first fuel or the second fuel, one or more of availability information or price information, and wherein the fuel market information includes fuel market information for one or more fuel stations along the fixed route, wherein the first fuel is diesel and the second fuel is natural gas, and wherein the first amount and second amount are selected to provide a fuel combustion ratio operative to exhaust a supply of the natural gas before a supply of the diesel. 3. The method of claim 1, wherein the route information includes one or more of projected mobile asset location information, projected fuel usage information, projected engine speed information, projected engine load information, projected engine emission information, or fuel station location information for one or more fuel stations along the fixed route, and wherein the first amount and second amount are further selected based on mobile asset operation information including one or more of actual engine speed information, actual engine load information, actual engine emission information, or actual mobile asset location information. 4. The method of claim 1, wherein the first amount and the second amount are further selected based upon mobile asset operation information including one or more of a quantity of at least one of the first or second fuels present in respective mobile asset fuel sources or actual fuel usage information. 5. The method of claim 4, wherein selecting the first amount and the second amount further based upon mobile asset operation information comprises determining a predicted first amount of the first fuel and a predicted second amount of the second fuel based at least in part on projected fuel usage information and adjusting the predicted first amount of the first fuel and the predicted second amount of the second fuel based on one or more of actual fuel usage information, actual engine speed information, actual engine load information, actual engine emission information, or actual mobile asset location information. 6. The method of claim 1, further comprising: receiving an update for at least one of the route information or the fuel market information during operation of the mobile asset; andadjusting at least one of the first amount or the second amount responsive to the update. 7. The method of claim 1, wherein at least one of the first amount or the second amount is further selected so that an actual emission level associated with usage of the first and second fuels is less than or equal to a determined emission level included in projected emission information associated with the fixed route. 8. The method of claim 7, further comprising supplying an engine exhaust with a third amount of the first fuel so that the actual emission level associated with usage of the first and second fuels is less than or equal to the determined emission level. 9. The method of claim 1, wherein at least one of the first amount and the second amount is further selected so that a ratio of the first and second amounts supplied to a cylinder of the engine is within a preselected range of fuel ratios. 10. The method of claim 1, further comprising selecting, from a plurality of fuel stations along the fixed route, a particular fuel station for refueling the mobile asset with at least one of the first or second fuels based upon the route information and the fuel market information so that the projected exhaustion of the first fuel does not precede the projected exhaustion of the second fuel. 11. The method of claim 1, wherein the first amount and the second amount are further selected so that the projected exhaustion of a particular fuel selected from the first fuel and the second fuel does not precede projected arrival of the mobile asset at a location where the mobile asset may be resupplied with that particular fuel. 12. A method for operating a consist, the method comprising: receiving route information for a fixed route along which the consist is traveling or will travel;receiving fuel market information for a first fuel and a second fuel, the first fuel and the second fuel being combustible in an engine in a first mobile asset of the consist;generating a motive power setting based upon the route information and the fuel market information so that a projected exhaustion of the first fuel does not precede a projected exhaustion of the second fuel; andsupplying with a fuel controller a first amount of the first fuel and a second amount of the second fuel to an engine in a mobile asset of the consist, wherein the first amount and the second amount are selected further based on a remaining quantity of the first fuel in a first fuel source and a remaining quantity of the second fuel in a second fuel source, and wherein the mobile asset is unable to operate with the second fuel alone. 13. The method of claim 12, wherein the consist comprises at least one second mobile asset, at least one of the at least one second mobile asset including a fuel tender. 14. The method of claim 13, wherein generating the motive power setting includes: generating a first engine power setting for the engine in the first mobile asset based upon the route information and the fuel market information; andgenerating a second engine power setting for an engine in the second mobile asset based upon the first engine power setting. 15. The method of claim 12, wherein the fuel market information includes, for at least one of the first fuel or the second fuel, at least one of availability information or price information, and where the route information includes at least one of projected mobile asset location information, projected fuel usage information, projected engine speed information, projected engine load information, projected engine emission information, or fuel station location information for one or more fuel stations along the fixed route, and further comprising generating a refueling plan based at least in part on the generated motive power setting. 16. The method of claim 12, further comprising: receiving an update for at least one of the route information and the fuel market information; and generating updated respective engine power settings for at least the first mobile asset and a second mobile asset included in the consist responsive to the update. 17. The method of claim 12, further comprising selecting, from a plurality of fuel stations along the fixed route, a particular fuel station for refueling the first mobile asset with one or more of the first fuel and the second fuel based upon the route information and the fuel market information so that the projected exhaustion of the first fuel does not precede the projected exhaustion of the second fuel. 18. An engine system, comprising: a fuel controller configured to determine a projected fuel supply rate to an engine for a first fuel of a plurality of fuels and a projected fuel supply rate to the engine for a second fuel of the plurality of fuels based upon route information about a fixed route along which a mobile asset powered by the engine is operable to travel; and adjust at least one of a first amount of the first fuel and a second amount of the second fuel supplied to the engine for combustion relative to the projected fuel supply rate for the first fuel and the projected fuel supply rate for the second fuel responsive to at least one of fuel market information for the plurality of fuels or mobile asset operational information. 19. The engine system of claim 18, wherein the fuel controller is further configured to adjust a third amount of at least one of the first and second fuels delivered to an exhaust fluidly coupled to the engine so that an actual emission level associated with usage of the plurality of fuels is less than or equal to a predefined emission level included in projected emission information associated with the fixed route. 20. The engine system of claim 19, wherein the at least one of the first and second fuels delivered to the exhaust is delivered through one or more of a cylinder of the engine during a post-injection fuel delivery event or an exhaust after treatment fuel injection location fluidly coupled to the exhaust. 21. The engine system of claim 19, wherein the fuel controller is further configured to adjust the third amount of the first and second fuels delivered to the exhaust responsive to an update to one or more of the route information and the fuel market information. 22. The engine system of claim 18, wherein the fuel controller is configured to adjust the first and second amounts of the first and second fuels, respectively, so that a projected exhaustion of the first fuel does not precede a projected exhaustion of the second fuel. 23.
