the at least one parameter includes a position of the first rail vehicle with respect to the position of the second rail vehicle in the consist.
4 . The system of claim 2 , wherein:
the processor has access to the information of the levels of non-propulsion consumable resources available on-board the first and second rail vehicles and is configured to create a schedule based on the information that manages the use of the non-propulsion consumable resources on-board the first and second rail vehicles.
5 . The system of claim 1 , wherein:
the non-propulsion consumable resource is a tractive material for use in an on-board tractive effort system.
6 . The system of claim 1 , wherein:
the non-propulsion consumable resource is compressed air.
7 . The system of claim 1 , wherein:
the communication link is a high-bandwidth communication link.
8 . The system of claim 1 , wherein:
the communication link is a remote or radio controlled communications link.
9 . The system of claim 1 , wherein:
the first rail vehicle is a lead rail vehicle and the first control unit is a master control unit; and
wherein the second rail vehicle is a trail rail vehicle.
10 . A system for rail vehicle control, the system comprising:
a control unit for a first rail vehicle in a consist, the control unit having a processor and being configured to receive signals indicative of amounts of a non-propulsion consumable resource available on-board the first rail vehicle and other rail vehicles in the consist; and
a set of instructions stored in a non-transient medium accessible by the processor, the instructions configured to control the processor to create a schedule that manages the use of the non-propulsion consumable resource by the consist based on the signals indicative of the amounts of the non-propulsion consumable resource available on-board the first and other rail vehicles in the consist.
11 . The system of claim 10 , wherein:
the non-propulsion consumable resource is a tractive material for use in an on-board tractive effort system.
12 . The system of claim 10 , wherein:
the non-propulsion consumable resource is compressed air.
13 . The system of claim 10 , wherein:
the control unit is configured to receive the signals indicative of the amounts of the non-propulsion consumable resource available on-board the first rail vehicle and other rail vehicles in the consist via a communication link between the first rail vehicle and other rail vehicles.
14 . The system of claim 13 , wherein:
the communication link is a high-bandwidth communications link.
15 . The system of claim 14 , wherein:
each of the rail vehicles in the consist includes a sensor for determining the amount of non-propulsion consumable resource on-board the rail vehicle; and
wherein each sensor is configured to communicate with the control unit for transmitting the amount of non-propulsion consumable resource thereto.
16 . A method for rail vehicle control, the method comprising the steps of:
receiving information of a determined first amount of a non-propulsion consumable resource available on-board a first rail vehicle in a consist;
receiving information of a determined second amount of the non-propulsion consumable resource available on-board a second rail vehicle in the consist; and
prioritizing use of the non-propulsion consumable resource in dependence upon the determined first and second amounts.
17 . The method according to claim 16 , further comprising the step of:
communicating the information of the determined first amount and the information of the information of the determined second amount between the first and second rail vehicle via a communication link, the communication link comprising one or more of wired or wireless distributed power, low bandwidth communications, or high bandwidth communications.
18 . The method according to claim 16 , wherein:
the step of prioritizing use of the non-propulsion consumable resource includes comparing the determined first amount of the resource on-board the first rail vehicle with the determined second amount of the resource on-board the second rail vehicle; and
controlling the first and second rail vehicles in the consist so as to utilize the resource from the first rail vehicle or the second rail vehicle having a greater amount of the resource.
19 . The method according to claim 16 , wherein:
the step of prioritizing the use of the non-propulsion consumable resource includes determining a position of the first rail vehicle with respect to the second rail vehicle within the consist.
20 . The method according to claim 16 , wherein the step of prioritizing use of the non-propulsion consumable resource comprises determining whether use of the non-propulsion consumable resource on the first rail vehicle is functionally fungible with use of the non-propulsion consumable resource on the second rail vehicle.
