Systems and methods for determining track location and/or direction of travel
First Claim
1. A system for determining a track location of a train including at least two locomotives or control cars and, optionally, at least one railroad car, in a track network having a plurality of tracks, the system comprising at least one computer programmed or configured to:
- receive or determine at least one location associated with at least one locomotive or control car of the train;
receive or determine at least one other location associated with at least one other locomotive or control car, wherein the at least one other locomotive or control car is different than the at least one locomotive or control car, and wherein the at least one other locomotive or control car is in the same train as the at least one locomotive or control car; and
determine a track of the plurality of tracks on which the train is located based at least partly on the at least one location associated with the at least one locomotive or control car and the at least one other location associated with the at least one other locomotive or control car.

Abstract
A system and method for determining a track location and/or a direction of travel of a train includes at least one computer programmed or configured to determine at least one of a track on which the train is located and a direction of travel of the train on the track based at least partly on at least one location associated with at least one locomotive or control car of the train and at least one other location associated with at least one other locomotive or control car of the train. The at least one computer can be programmed or configured to determine a track on which the train is located based at least partly on the at least one location associated with the at least one locomotive or control car of the train and at least one additional location associated with at least one additional locomotive or control car of at least one additional train.

13. A system for determining a direction of travel of a train including at least two locomotives or control cars and, optionally, at least one railroad car, in a track network having a plurality of tracks, the system comprising at least one computer programmed or configured to:
-
receive or determine a direction of orientation of a lead locomotive of the train on a track before the train moves after an initialization of the lead locomotive or control car; receive or determine a reverser handle position of the lead locomotive of the train before the train moves after the initialization of the lead locomotive or control car; and determine, based on the direction of orientation and the reverser handle position, the direction of travel of the train on the track before the train moves after the initialization of the lead locomotive or control car. - View Dependent Claims (14)

15. A computer implemented method for determining a track location of a train including at least two locomotives or control cars and, optionally, at least one railroad car, in a track network having a plurality of tracks, the method comprising:
-
receiving or determining at least one location associated with at least one locomotive or control car of the train; receiving or determining at least one other location associated with at least one other locomotive or control car, wherein the at least one other locomotive or control car is different than the at least one locomotive or control car, and wherein the at least one other locomotive or control car is in the same train as the at least one locomotive or control car; and determining a track of the plurality of tracks on which the train is located based at least partly on the at least one location associated with the at least one locomotive or control car and the at least one other location associated with the at least one other locomotive or control car.

16. A computer implemented method for determining a direction of travel of a train including at least two locomotives or control cars and, optionally, at least one railroad car, in a track network having a plurality of tracks, the method comprising:
-
receiving or determining a direction of orientation of a lead locomotive of the train on the track before the train moves after an initialization of the lead locomotive or control car; receiving or determining a reverser handle position of the lead locomotive of the train before the train moves after the initialization of the lead locomotive or control car; and determining based on the direction of orientation and the reverser handle position the direction of travel of the train on the track before the train moves after the initialization of the lead locomotive or control car.

17. A system for determining a track location of a train including at least one locomotive or control car and, optionally, at least one railroad car, in a track network having a plurality of tracks, the system comprising at least one computer programmed or configured to:
-
receive or determine at least one location associated with the at least one locomotive or control car of the train; receive or determine at least one additional location associated with at least one additional locomotive or control car of at least one additional train in the track network, wherein the at least one additional locomotive or control car is different than the at least one locomotive or control car, and wherein the at least one additional train in the track network is different than the train in the track network; receive or determine track centerline data associated with a centerline of a track of the plurality of tracks on which the at least one additional train is located; determine, based on the at least one additional location associated with the at least one additional locomotive or control car of the at least one additional train in the track network and the track centerline data, an amount of skew associated with the at least one additional location of the at least one additional locomotive or control car of the at least one additional train; adjust the at least one location associated with the at least one locomotive or control car of the train based on the amount of skew associated with the at least one additional location; and determine a track of the plurality of tracks on which the train is located based at least partly on the adjusted at least one location associated with the at least one locomotive or control car of the train. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A computer implemented method for determining a track location of a train including at least one locomotive or control car and, optionally, at least one railroad car, in a track network having a plurality of tracks, the method comprising:
-
receiving or determining at least one location associated with the at least one locomotive or control car of the train; receiving or determining at least one additional location associated with at least one additional locomotive or control car of at least one additional train in the track network, wherein the at least one additional locomotive or control car is different than the at least one locomotive or control car, and wherein the at least one additional train in the track network is different than the train in the track network; receiving or determining track centerline data associated with a centerline of a track of the plurality of tracks on which the at least one additional train is located; determining, based on the at least one additional location associated with the at least one additional locomotive or control car of the at least one additional train in the track network and the track centerline data, an amount of skew associated with the at least one additional location of the at least one additional locomotive or control car of the at least one additional train; adjusting the at least one location associated with the at least one locomotive or control car of the train based on the amount of skew associated with the at least one additional location; and determining a track of the plurality of tracks on which the train is located based at least partly on the adjusted at least one location associated with the at least one locomotive or control car of the train.
