Abstract

A rail conditioning system associated with a locomotive is provided. The locomotive operates on a rail. The rail conditioning system includes a fluid supply tank. The rail conditioning system also includes a first nozzle coupled to the locomotive. The first nozzle is adapted to direct a first beam of fluid received from the fluid supply tank towards a first portion of the rail. The rail conditioning system further includes a second nozzle coupled to the locomotive. The second nozzle is adapted to direct a second beam of fluid received from the fluid supply tank towards a second portion of the rail. The rail conditioning system includes a valve element provided in fluid communication with the first and second nozzles. The rail conditioning system further includes a control module in communication with the valve element.

First claim

What is claimed is:

1. A rail conditioning system associated with a locomotive, the locomotive operating on a rail, the rail conditioning system comprising:
a fluid supply tank mounted on the locomotive;
a first nozzle coupled to the locomotive, wherein the first nozzle is in selective fluid communication with the fluid supply tank, the first nozzle adapted to direct a first beam of fluid received from the fluid supply tank towards a first portion of the rail;
a second nozzle coupled to the locomotive, wherein the second nozzle is in selective fluid communication with the fluid supply tank, the second nozzle adapted to direct a second beam of fluid received from the fluid supply tank towards a second portion of the rail;
a valve element in fluid communication with the first and second nozzles;
a sensor assembly including a sensor structured to generate a signal indicative of operating the locomotive on a rail having a curved configuration; and
a control module in communication with the valve element, the control module configured to control the valve element to activate each of the first and second nozzles based on a tangent configuration of the rail, and to selectively activate only one of the first or second nozzles based on a curved configuration of the rail.

2. The rail conditioning system of claim 1 , wherein a total volume of fluid supplied by the fluid supply tank is split such that a volume of the first beam of fluid is equal to a volume of the second beam of fluid based on the activation of each of the first and second nozzles.

3. The rail conditioning system of claim 1 , wherein the fluid is pressurized air.

4. The rail conditioning system of claim 1 , wherein the sensor assembly includes at least one of a non-contact type sensing element or a contact type sensing element, the sensor assembly being communicably coupled with the control module, and configured to generate a signal corresponding to a turning motion of the locomotive to determine the curved configuration of the rail.

5. The rail conditioning system of claim 1 , wherein the first and second nozzles are angled downwardly towards the rail such that, when the rail is in the tangent configuration, the first and second portions are defined at an outer third and an inner third portion of the rail, respectively.

6. The rail conditioning system of claim 1 , wherein the first and second nozzles are provided in a laterally spaced arrangement on opposing sides of a wheel of the locomotive.

7. The rail conditioning system of claim 1 , wherein the first and second portions lie on opposite sides of a central portion of the rail when the rail is in a tangent configuration.

8. The rail conditioning system of claim 1 , wherein only one of the first or the second portion is defined at a central portion of the rail when the rail is in a curved configuration.

9. The rail conditioning system of claim 1 , wherein the control module is structured to control fluid delivery to split a total volume of fluid supplied by the fluid supply tank such that a volume of the first beam of fluid is equal to a volume of the second beam of fluid based on the tangent configuration of the rail.

10. A rail conditioning system for a locomotive, the locomotive operating on a rail, the rail conditioning system comprising:
a fluid supply tank mounted on the locomotive;
a first nozzle coupled to the locomotive, wherein the first nozzle is in selective fluid communication with the fluid supply tank, the first nozzle adapted to direct a first beam of fluid received from the fluid supply tank towards the rail;
a second nozzle coupled to the locomotive, wherein the second nozzle is in selective fluid communication with the fluid supply tank, the second nozzle adapted to direct a second beam of fluid received from the fluid supply tank towards the rail;
a valve element in fluid communication with the fluid supply and the first and second nozzles;
a sensor assembly including a sensor structured to generate a signal indicative of operating the locomotive on a rail having a curved configuration; and
a control module in communication with the valve element and the sensor assembly, the control module configured to control the valve element to selectively activate only one of the first nozzle or the second nozzle based on the signal indicative of operating the locomotive on a rail having a curved configuration of the rail for directing the first beam of fluid or the second beam of fluid towards the central portion of the rail.

11. The rail conditioning system of claim 10 , wherein the control module is further configured to control the valve element to place activate each of the first and second nozzles in fluid communication with the fluid supply tank when the rail is in a tangent configuration with respect to the locomotive.

12. The rail conditioning system of claim 11 , wherein the control module is structured to split a total volume of fluid supplied by the fluid supply tank such that a volume of the first beam of fluid is equal to a volume of the second beam of fluid based on a signal indicative of a tangent configuration of the rail.

13. The rail conditioning system of claim 11 , wherein the first and second nozzles project angularly downwards from the locomotive towards the rail such that the first and second beams of fluid are directed towards opposite sides of the central portion of the rail when the rail is in a tangent configuration with respect to the locomotive.

14. The rail conditioning system of claim 13 , wherein the first and second beams of fluid are directed towards an outer third portion of the rail and an inner third portion of the rail, respectively, when the rail is in a tangent configuration with respect to the locomotive.

15. The rail conditioning system of claim 13 , wherein a total volume of fluid supplied by the fluid supply tank is split such that a volume of the first beam of fluid is equal to a volume of the second beam of fluid based on the activation of each of the first and second nozzles.

16. The rail conditioning system of claim 10 , wherein the control module is configured to control an outflow of fluid from the fluid supply tank to provide a maximum fluid pressure to only one of the first nozzle or the second nozzle when the rail is in a curved configuration with respect to the locomotive.

17. The rail conditioning system of claim 10 , wherein the sensor assembly includes at least one of a non-contact type sensing element or a contact type sensing element.

18. The rail conditioning system of claim 17 , wherein the sensor assembly includes a gyro sensor.

19. The rail conditioning system of claim 10 , wherein the sensor assembly is further structured to generate a signal indicative of operating the locomotive on a rail having a tangent configuration.
