Abstract

A computer program product for a computer system including a processor, a display, a historical database, and a geographic database, for determining railway defects includes a computer readable memory including code that directs the processor to receive positional data and status data for a portion of a railway, code that directs the processor to retrieve historical status data for the portion of the railway in response to the positional data from the historical database, code that directs the processor to compare the historical status data to the status data to determine a defect for the portion of the railway, code that directs the processor to retrieve an image of a geographic region in response to the positional data from the geographic database, code that directs the processor to determine an icon in response to the defect, and code that directs the display to display the image of the geographic region and the icon for the defect.

Claims

1. A computer system for displaying railway defects, the computer system comprising:

a receiver for receiving positional data and current status data for a portion of a railway;

a historical database for retrieving historical status data for the portion of the railway in response to the positional data;

a processor for comparing the historical status data to the current status data to determine a difference in the two sets of data which may indicate a defect occurring over time for the portion of the railway;

a geographic database for forming an image of a geographic region in response to the positional data;

an overlay generator for forming an overlay image in response to the defect; and

a display for displaying the image of the geographic region and the overlay image.

2. The computer system of claim 1 further comprising:

a railway database for retrieving railway data for the portion of the railway in response to the positional data; and

wherein the display is used for displaying the railway data.

3. The computer system of claim 1 further comprising:

a resource status module for determining a repair resource in the geographic region in response to the positional data; and

wherein the overlay for the image includes an icon representing the repair resource.

4. The computer system of claim 3 further comprising:

a work order processing module for generating a work order for the defect for the repair resource.

5. The computer system of claim 4 wherein the overlay for the image includes an icon representing the work order.

6. The computer system of claim 4 further comprising:

a job status module for monitoring status of the work order.

7. The computer system of claim 6 wherein the overlay for the image includes an icon representing the status of the work order.

8. A computer program product for a computer system including a processor, a display, a historical database, and a geographic database, for determining railway defects, the computer system comprising:

a computer readable memory including;

code that directs the processor to receive positional data and current status data for a portion of a railway;

code that directs the processor to retrieve historical status data for the portion of the railway in response to the positional data from the historical database;

code that directs the processor to compare the historical status data to the current status data to determine a difference in the two sets of data which may indicate a defect occurring over time for the portion of the railway;

code that directs the processor to retrieve an image of a geographic region in response to the positional data from the geographic database;

code that directs the processor to determine an icon in response to the defect; and

code that directs the display to display the image of the geographic region and the icon for the defect.

9. The computer program product of claim 8 wherein the computer readable memory also includes:

a railway database for retrieving railway data for the portion of the railway in response to the positional data; and

code that directs the display to display the railway data.

10. The computer program product of claim 8 wherein the computer readable memory also includes:

code that directs the processor to determine a repair resource in the geographic region in response to the positional data; and

code that directs the display to display an icon for the repair resource.

11. The computer program product of claim 10 wherein the computer readable memory also includes:

code that directs the processor to generate a work order for the defect for the repair resource.

12. The computer program product of claim 11 wherein the computer readable memory also includes:

code that directs the display to display an icon for the work order.

13. The computer program product of claim 11 wherein the computer readable memory also includes:

code that directs the processor to monitor a status of the work order.

14. The computer program product of claim 13 wherein the computer readable memory also includes:

code that directs the display to display an icon for the status of the work order.

15. A method for determining railway defects in a computer system including a display, a historical database, and a geographic database, the method comprising:

receiving positional data and current status data for a rail track;

retrieving historical status data from the historical database for the rail track in response to the positional data;

comparing the historical status data to the current status data to determine a difference in the two sets of data which can indicate a defect occurring over time for the rail track, if any, the defect having a defect type;

displaying an image of a geographic region from the geographic database on the display in response to the positional data; and

displaying an icon on the display in response to the defect type, if any.

16. The method of claim 15 further comprising

retrieving rail track data from a rail track database for the portion of the railway in response to the positional data;

and

displaying the rail track data on the display.

17. The method of claim 15 further comprising

determining a repair resource from a repair resource database in response to the positional data;

and

displaying an icon representing the repair resource on the display.

18. The method of claim 17 further comprising:

generating a work order for the defect for the repair resource.

19. The method of claim 18 further comprising:

displaying an icon representing the work order on the display.

20. The method of claim 18 further comprising:

monitoring the status of the work order.

21. The method of claim 20 further comprising:

displaying an icon representing the status of the work order on the display.
