Abstract

A system and method for controlling the movement of plural trains over a rail network, where the rail network is divided into at least one control area with a dispatcher assigned to manage the movement of trains in a control area by predicting the occurrence of events along the network based on the movement plan and prompting the dispatcher to provide information or take specified actions relating to the predicted events.

Claims

1. A method of controlling the movement of plural trains over a network of tracks using a network wide computer-based movement planner which creates a movement plan for planning the movement of the trains traveling over the network, the network having a dispatcher being assigned to manage the movement of trains in accordance with the movement plan, comprising:

predicting the occurrence of events along the network based on the movement plan;

prompting the dispatcher to take specific actions as a function of the predicted events,

wherein said prompting is a function of non-compliance of actual events with the predicted events, and wherein said prompting includes requesting the dispatcher to provide information about the non-compliance; and

modifying the movement plan using the information provided by the dispatcher;

wherein the information comprises a cause of train delay, and wherein the movement plan is modified using the cause of train delay and to account for additional expected delays based on the cause for train delay.

2. The method of claim 1 wherein said prompting comprises:

(i) generating a task list of activities to be performed by the dispatcher as a function of the predicted occurrence of events; and

(ii) monitoring the completion of the activities specified on the task list by the dispatcher.

3. The method of claim 1 wherein said predicting includes accessing historical performance information to predict future compliance with movement plan.

4. The method of claim 3 wherein said accessing comprises accessing information relating to configuration of work locations for trains performing specific types of activities.

5. The method of claim 1 wherein said predicting includes determining train performance as a function of train characteristics.

6. A method of controlling the movement of plural trains over a network of tracks using a network wide computer-based movement planner which creates a movement plan for planning the movement of the trains traveling over the network, the network having at least one control area with a dispatcher being assigned to manage the movement of trains for a control area in accordance with the movement plan, comprising:

generating a task list of activities to be performed by the respective dispatcher as a function of the movement plan, wherein said generating comprises;

receiving movement reports regarding the trains in the control area, and prompting a desired activity by the dispatcher on the basis of the non-receipt of a movement report;

monitoring the execution of the activities specified on the task list by the dispatcher;

prompting the dispatcher to provide information relating to the non-receipt of the movement report, said prompting including transmitting a form to the dispatcher that is required to be submitted for providing the information; and

updating the movement plan as a function of the information provided by the dispatcher.

7. The method of claim 6 wherein said generating further comprises:

(i) monitoring the movement of trains through the control area, and (ii) prompting a desired activity of the dispatcher as a function of the movement of the trains.

8. The method of claim 6 wherein said prompting comprises notifying the dispatcher to assign a helper locomotive.

9. A method of controlling the movement of plural trains over a network of tracks using a network wide computer-based movement planner which creates a movement plan for planning the movement of the trains traveling over the network, the network having a dispatcher being assigned to manage the movement of trains in accordance with the movement plan, comprising:

monitoring the movement of trains in accordance with the movement plan;

identifying incidents of non-conformance with the movement plan;

alerting the respective dispatcher of an identified incident;

prompting the dispatcher to provide information about the identified incident;

updating the movement plan as a function of the information provided by the dispatcher; and

wherein said monitoring includes receiving periodic movement reports from the train and wherein said identifying includes determining non-receipt of an expected movement report.

10. The method of claim 9 wherein said alerting includes the step of prompting the dispatcher to provide information related to the identified incident.

11. The method of claim 9 wherein said alerting includes communicating information relating to an identified incident for at least one train of a linked activity.
