System and method of transforming movement authority limits

A computer-implemented method of transforming movement authority limits for a train traveling in a track network, comprising:

• receiving, by at least one of a back office system, an on-board segment, and a wayside segment, authority data and/or train authority data provided by a dispatch system;
• determining, by the at least one of the back office system, the on-board segment, and the wayside segment, authority associated with a first track segment located on a first track, a second track segment located on a second track, and a switch leg of a switch located on the first track based at least partially on the authority data and/or train authority data provided by the dispatch system, wherein the first track segment and the second track segment are located at opposite ends of a crossover track between the first track and the second track, wherein the authority data and/or train authority provided by the dispatch system data does not include authority associated with the switch leg and the crossover track;
• and
• providing, by the at least one of the back office system, the on-board segment, and the wayside segment, authority on the crossover track based at least partially on the determined authority associated with the first track segment, the second track segment, and the switch leg.

A computer-implemented method of transforming movement authority limits for a train traveling in a track network, comprising:

• receiving, by at least one of a back office system, an on-board segment, and a wayside segment, authority data and/or train authority data provided by a dispatch system;
• determining, by the at least one of the back office system, the on-board segment, and the wayside segment, authority associated with a track segment, and a first switch leg of a switch based at least partially on the authority data and/or train authority data provided by the dispatch system, wherein the authority data and/or train authority data provided by the dispatch system does not include authority associated with the first switch leg of the switch and a second switch leg of the switch, wherein the track segment is adjacent to the switch, such that the switch is located between the track segment and the first switch leg;
• and
• providing, by the at least one of the back office system, the on-board segment, and the wayside segment, authority on the second switch leg based at least partially on the determined authority associated with the track segment and the first switch leg.

A computer-implemented method of transforming movement authority limits for a train traveling in a track network, comprising:

• receiving, by a management system on the train traveling in the network, authority data and/or train authority data provided by a dispatch system;
• determining, by the management system on the train traveling in the network, authority associated with a switch leg, a first track segment including a point of switch, and a second track segment based at least partially on the authority data and/or train authority data provided by the dispatch system, wherein the authority data and/or train authority data provided by the dispatch system does not include authority associated with the switch leg, wherein the first track segment is adjacent to a switch and the second track segment is adjacent to the switch leg of the switch, such that the switch and the switch leg are located between the first track segment and the second track segment;
• and
• providing, by the management system on the train traveling in the network, authority on the switch leg based at least partially on the determined authority associated with the switch leg, the first track segment, and the second track segment.

A computer-implemented method of transforming movement authority limits for a train traveling in a track network, comprising:

• receiving, by a back office system of a Positive Train Control (PTC) system including a plurality of different track networks including a plurality of different dispatch systems, authority data in a single authority dataset message provided by a dispatch office of the plurality of different dispatch systems;
• determining, by the back office system of the PTC system, authority associated with a first track segment located on a first track, a second track segment located on a second track, and a switch leg of a switch located on the first track based at least partially on the authority data provided in the single authority dataset message by the dispatch office, wherein the first track segment and the second track segment are located at opposite ends of a crossover track between the first track and the second track, wherein the authority data provided in the single authority dataset message by the dispatch office does not include authority associated with the crossover track;
• and
• providing, by the back office system of the PTC system, authority on the crossover track based at least partially on the determined authority associated with the first track segment, the second track segment, and the switch leg, in response to receiving the single authority dataset message that contains authority for at least a portion of the first track segment, at least a portion of the second track segment, and at least a portion of the switch leg.
