Method and apparatus for selectively disabling train location reports
First Claim
1. In a railway scheduling system in which each resource used in each scheduled activity has an incremental cost associated with it, and in which train location reports are automatically provided to the scheduler as an aid in the updating the schedule, a method of selectively disabling train location reports comprising:
- (a) assigning a local movement activity to a selected train at a selected location;
(b) automatically disabling the generation of train location reports by the selected train as a function of the distance of the train from the selected location.

Abstract
A scheduling system and method for moving plural objects through a system described as a freight railway scheduling system. The scheduling system utilizes a cost reactive resource scheduler to minimize resource exception while at the same time minimizing the global costs associated with the solution. The achievable movement plan can be used to assist in the control of, or to automatically control, the movement of trains through the system. Train location reports used in the automatic updating of the movement plans are selectively disabled for individual trains as a function of the activity scheduled for that train.

5. A method of preventing the impact of automatically generated train location reports on the movement plan for the system comprising the selective disabling of the movement planner for information related to the location of specifically identified trains.

6. In a railroad system in which plural trains are moved along a network of railway tracks under control of a dispatcher assisted by a scheduling computer prepared movement plan that assigns resources to activities and considers the cost of each activity and assigned resources in scheduling the movement of trains over the tracks,
and in which information as to the location of trains is automatically provided to the movement planner for use in modifying the movement plan for the system, the improvement comprising the step of disabling the use of train location information for trains that have been assigned activities that require local movement.
