Abstract

A system and method for planning and monitoring rail yard processes and performance including compiling historical information, real time status display of rail yard activity, the development of parameters and metrics to evaluate rail yard performance, collection of rail yard status from various sensors, and the planning and assigning of work tasks for enhanced productivity and car processing capability.

Claims

1. In a rail yard having a plurality of arriving trains, and a plurality of resources in which to process the trains through the rail yard, a method of planning the movement of a train through the rail yard comprising the steps of:

a. displaying a plurality of arriving trains;

b. selecting one of the displayed arriving trains;

c. displaying one or more available tracks as a function of the selected train;

d. selecting one of the available tracks;

e. displaying one or more processes to be performed on the selected train;

f. selecting one of the displayed processes;

g. planning the movement of the selected train on the selected track as a function of the selected process; and

h. displaying the planned movement of the selected train as a function of the selected track and the selected process.

2. The method of claim 1 wherein the step of planning the movement further comprises:

(i) accessing a database having historical information for the selected process;

(ii) estimating the time to perform the selected process; and

(iii) displaying the planned movement as a function of the estimated time.

3. The method of claim 1 further comprising:

i. monitoring the actual movement of the selected train;

j. comparing the actual movement of the selected train with the planned movement of the selected train; and

k. displaying an alert when the actual movement deviates from the planned movement by a predetermined amount.

4. The method of claim 3 wherein the selected track is a receiving track and the selected process is inspection.

5. The method of claim 1 wherein

the step of displaying one or more processes to be performed includes displaying one or more crews to perform the process, and

the step of selecting one of the displayed processes includes selecting one of the displayed crews

6. The method of claim 5 wherein the step of planning the movement further comprises:

(i) accessing a database having historical information for the selected crew;

(ii) estimating the time for the selected crew to perform a process; and

(iii) displaying the planned movement as a function of the estimated time.

7. The method of claim 1 wherein the selected track and selected process is displayed as not available to other trains during the planned movement.

8. The method of claim 3 wherein the predetermined amount is determined by the steps comprising:

(a) accessing a database having historical information for the selected process; and

(ii) calculating a predetermined amount as a function of the accessed historical information for the selected process.

9. The method of claim 1 wherein the steps of selecting comprise at least one of double clicking on the display or drag and drop technology.

10. In a rail yard having an arriving train with a plurality of railcars, and a plurality of resources in which to process the railcars through the rail yard to build a plurality of departing trains, a method of planning the movement of the railcars through the rail yard comprising the steps of:

a. collecting historical data relating to the movement of railcars through a rail yard;

b. developing parameters to track the progress of the processes performed on the railcars based on the collected historical data;

c. determining metrics which quantitize the developed parameters;

d. planning the movement of the railcars through the yard as a function of the collected historical data;

e. monitoring the actual movement of the railcars through the yard;

f. comparing the actual movement of the railcars with the determined metrics; and

g. providing an alert when actual movement exceeds a determined metric by a predetermined threshold.

11. The method of claim 10 wherein the developed parameters comprise at least one of performance of a crew, performance of a class yard, and dwell variance.

12. The method of claim 10 wherein the collected historical data is maintained in a database.

13. The method of claim 10 where the planned movement of the railcars is displayed, and wherein the provided alert is displayed on a user monitor.

14. The method of claim 13, wherein the user may modify the planned movement in response to the alert by using the display.

15. The method of claim 14 wherein the modification may be made using drag and drop technology.

16. The method of claim 10 wherein the step of collecting historical data comprises collecting data from one or more sensors selected from the group of AEI tag readers, wheel detectors, cut-light sensors, track circuits, imaging devices, gravity sensors and location sensors.

17. The method of claim 16 wherein the one or more sensors are portable and carried by rail yard personnel.

18. The method of claim 10 wherein the step of collecting historical data comprises collecting data from sensors using wireless communication links.

19. The method of claim 10 wherein the step of collecting historical data comprises collecting data from a second rail yard.

20. The method of claim 10 wherein the determined metrics relate to plan performance and include at least one of dwell variance between proposed plan and locked-in plan, dwell variance between proposed plan and executed plan, variance in percentage of trains filled out and fill percentage, variance in class yard performance, variance in total cars through, and variance in percentage of resources used.

21. The method of claim 10 wherein the determined metrics relate to crew performance and include at least one of number of cars processed per crew per unit time, percentage of time a crew is used, time remaining before end of a crew shift.

22. The method of claim 10 wherein the determined metrics relate to classification yard performance and include at least one of average length of time car spends in classification yard, percentage of day that classification yard track is in use, number of cars left behind on train departure, number of car misroutes, accuracy of hump plan, number of slough tracks.

23. The method of claim 10 where the determined metrics relate to yard switch engine performance and include at least one of number of rail cars pulled from receiving yard versus time, number of rail cars pulled from classification yard versus time, engine utilization over 8 hours.

24. The method of claim 10 where the determined metrics relate to railcar repair and include at least one of time to repair versus repair code, capacity of repair tracks.
