Method for run-time incorporation of domain data configuration changes

1. A method comprising:

developing a first change set of intended modifications to domain data of a train dispatching system, wherein the domain data defines physical assets and devices that make up a rail network over which plural trains travel;

developing a second change set of intended modifications to the domain data which reverses the modifications made by the first change set;

implementing the first change set to a domain data baseline in real-time while the dispatching system remains online and operational to users of the dispatching system during implementation of the modification to the domain data, including:

determining the domain data to be modified by the first change set;

preventing the implementation of the first change set if the domain data to be modified is currently being accessed by the dispatching system; and

notifying a user if the implementation of the first change set is prevented;

evaluating the operational implementation of the first change set in real time against a predetermined criterion; and

implementing the second change set in real time if the evaluation of the first change set does not satisfy the predetermined criterion to return the domain data to the domain data baseline.

2. The method of claim 1 , wherein the step of implementing a first change set comprises:

determining the domain data to be modified by the first change set; and

making the domain data to be modified inaccessible to users of the dispatching system until the first change set has been successfully implemented.

3. The method of claim 2 , wherein the step of implementing the first change set further comprises preventing the implementation of the first change set if the domain data to be modified is currently being accessed by the dispatching system.

4. The method of claim 3 , wherein the accessed domain data that is preventing the implementation of the first change set is identified to a user of the dispatching system.

5. The method of claim 4 , wherein the accessed domain data that is preventing the implementation of the first change set is identified to a user by a graphical user interface.

6. The method of claim 2 , wherein the step of making the domain data inaccessible includes disabling context menus and functions in a graphical user interface.

7. The method of claim 1 , wherein the step of implementing the first change set comprises:

identifying the domain data to be modified by the first change set that is subject to a safety constraint; and

applying the safety constraint to the identified domain data prior to implementation of the modifications.

8. The method of claim 7 , wherein the safety constraint comprises a track block.

9. The method of claim 7 , wherein the step of implementing the first change set further comprises reapplying the safety constraint following implementation of the modifications.

10. The method of claim 1 , wherein a movement plan for controlling the movement of the plural trains over plural track resources of the rail network is automatically generated following successful implementation of the first change set.

11. The method of claim 1 , wherein the domain data defines at least one of switches, track segments, or signals.

12. A method comprising:

developing a first change set of intended modifications to domain data of a train dispatching system, wherein the domain data defines physical assets and devices that make up a rail network over which plural trains travel;

developing a second change set of intended modifications to the domain data which reverses the modifications made by the first change set;

implementing the first change set to a domain data baseline in real-time while the dispatching system associated with the domain data remains online and operational to users of the dispatching system during implementation of the modification to the domain data, including:

determining the domain data to be modified by the first change set;

preventing the implementation of the first change set if the domain data to be modified is currently being accessed by the dispatching system; and

notifying a user if the implementation of the first change set is prevented;

evaluating the operational implementation of the first change set in real time against a predetermined criteria; and

implementing the second change set in real time if the evaluation of the first change set does not satisfy the predetermined criteria to return the domain data to the domain data baseline.

13. A method comprising:

developing a first change set of intended modifications to domain data of a train dispatching system configured to control movement of plural trains over plural track resources, wherein the domain data defines the plural track resources;

determining the domain data to be modified by the first change set;

making the domain data to be modified inaccessible to users of the dispatching system until the first change set has been successfully implemented; and

implementing the first change set to a domain data baseline, including preventing the implementation of the first change set if the domain data to be modified is currently being accessed by the dispatching system, wherein the dispatching system associated with the domain data remains online and operational to users of the dispatching system during implementation of the modification to the domain data.

14. A method for controlling the movement of plural trains in a train dispatching system comprising the steps of:

defining a plurality of track resources by domain data;

developing a first change set of intended modifications to the domain data;

developing a second change set of intended modifications to the domain data which reverses the modifications made by the first change set;

implementing the first change set to a domain data baseline including: identifying the domain data to be modified by the first change set that is subject to a track block, applying the track block to the identified domain data prior to implementation of the modifications, and reapplying the track block following implementation of the modifications;

evaluating the operational implementation of the first change set against a predetermined criteria; and

implementing the second change set if the evaluation of the first change set does not satisfy the predetermined criteria to return the domain data to the domain data baseline, wherein the dispatching system associated with the domain data remains online and operational to users of the dispatching system during implementation of the modification to the domain data.
