Scheduler and method for managing unpredictable local trains
First Claim
1. A method of scheduling the sporadic use of the main railway track of a railway network to local trains in which one or more multiple car throughway trains are moved along the main railway track under control of a dispatcher assisted by a scheduling computer prepared plan, comprising:
- (a) electronically receiving a request for a work order for a local train to use the main railway track in a dispatching computer;
(b) displaying the work request as an unassigned work request for the dispatcher;
(c) selecting the displayed unassigned work request to be performed by a selected local train;
(d) electronic sending the selected work request for the selected local train to the scheduling computer;
(e) planning the movement of the local train in the scheduling computer; and
(f) electronically communicating to the dispatching computer that the work request has been planned for the selected train.

Abstract
A scheduling system and method for moving plural objects through a multipath 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, and is particularly useful in managing the unpredictable movement of local industry trains.

3. A method of assisting a train dispatcher, who receives an order for movement of local industry trains requiring that the dispatcher provide access a main railway track from time to time, in controlling the interaction of the movement of the local industry train along the main railway track with the computer planned movement of a throughway train, said method comprising the steps of:
-
(a) using a scheduling computer to prepare a plan for the movement of plurality of multiple car throughway trains along a main railway track;
(b) receiving a work request for movement of a local industry train along the main railway track;
(c) inserting into the scheduling computer the work request for the then unscheduled movement of a specific local industry train along the main railway track; and
(d) modifying the computer prepared movement plan to include the movement of the local industry train. - View Dependent Claims (4, 5)

6. In a railroad system in which one or more multiple car throughway trains are moved along a main railway track under control of a dispatcher assisted by a scheduling computer prepared plan that receives work orders for activities to be performed by assigned resources, assigns time intervals to every activity, and assigns available resources to scheduled activities, and
where a dispatcher receives an order for movement of a local industry train requiring access to the main railway track, the improvement wherein the movement of the local industry train is integrated into the plan by the scheduling computer rather than manually scheduled by the dispatcher so as not to interfere with the scheduled movement of throughway trains.
