Communication system for use with train consist

1. A method of communicating a locomotive with a tender car, comprising:

transmitting between the locomotive and the tender car operational data captured by network components located onboard at least one of the locomotive and the tender car; and

selectively adjusting, via a controller having a processor, an operation of at least one of the locomotive and the tender car based on the data;

wherein the operational data includes operational data captured by network components located onboard both of the locomotive and the tender car; and

wherein the operational data includes a level of liquid fuel stored onboard the first locomotive being different than a level of liquid fuel stored onboard the second locomotive;

wherein selectively adjusting an operation includes selectively adjusting operation of an engine located onboard the locomotive; wherein;

the locomotive is a first locomotive;

the engine is a first engine; and

transmitting operational data includes transmitting operational data between the first locomotive, a second locomotive, and the tender car; and

selectively adjusting the operation includes selectively adjusting an operation of the first engine different than an operation of a second engine located onboard the second locomotive; and

wherein selectively adjusting the operation includes selectively adjusting a supply rate of gaseous fuel from the tender car to the first locomotive different than a supply rate of gaseous fuel from the tender car to the second locomotive based on the different levels of liquid fuel stored onboard the first and second locomotives.

2. The method of claim 1 , wherein:

the method further includes determining a first distance between the first locomotive and the tender car and a second distance between the second locomotive and the tender car; and

selectively adjusting an operation includes selectively adjusting a supply of gaseous fuel from the tender car to the first and second engines differently based on the first and second distance.

3. The method of claim 1 , wherein:

the method further includes determining a difference in operational performance between the first and second engines; and

selectively adjusting an operation includes selectively adjusting a supply of gaseous fuel from the tender car to the first and second engines differently based on the difference in operational performance.

4. The method of claim 3 , wherein the difference in operational performance includes a difference in at least one of efficiency and temperature.

5. The method of claim 1 , further including determining a fault condition based on the operational data, wherein selectively adjusting an operation includes selectively adjusting the operation only when the fault condition is determined to be critical.

6. The method of claim 5 , further including communicating, via a communication device connectable with a controller equipped on at least one of the first locomotive, the second locomotive, and the tender car the fault condition to an offboard entity.

7. A method of communicating a locomotive with a tender car, comprising:

transmitting between the locomotive and the tender car operational data captured by network components located onboard at least one of the locomotive and the tender car; and

selectively adjusting, via a controller having a processor, an operation of at least one of the locomotive and the tender car based on the data;

wherein the operational data includes operational data captured by network components located onboard both of the locomotive and the tender car; and

wherein the operational data includes at least one of a speed, a load, a temperature, a flow rate, a pressure, a voltage, a current, a desired fuel setting, braking data, a fuel supply rate, a fuel consumption rate, a change in demand for gaseous fuel, a fuel level of the at least one of the locomotive and the tender car, a level of liquid fuel stored onboard the first locomotive being different than a level of liquid fuel stored onboard the second locomotive, a fuel consumption rate of the locomotive and a fuel supply rate of the tender car, and a level of liquid fuel stored onboard the locomotive and a level of gaseous fuel stored onboard the tender car;

wherein selectively adjusting an operation includes selectively adjusting operation of a least one of a pump, a heat exchanger, an accumulator, and a regulator located onboard the tender car; and

wherein selectively adjusting operation includes selectively adjusting operation of at least one of a rate of fuel supply to an engine located onboard the locomotive and a fuel blend ratio.

8. A method of communicating a locomotive with a tender car, comprising:

transmitting between the locomotive and the tender car operational data captured by network components located onboard at least one of the locomotive and the tender car; and

selectively adjusting, via a controller having a processor, an operation of at least one of the locomotive and the tender car based on the data;

wherein the operational data includes operational data captured by network components located onboard both of the locomotive and the tender car; and

wherein the operational data includes a fuel consumption rate of the locomotive and a fuel supply rate of the tender car;

the method further includes determining fuel leakage based on a difference between the fuel consumption and supply rates; and

selectively adjusting includes selectively adjusting the operation of at least one of the locomotive and the tender car based on the fuel leakage.
