  • Publication number: 20200198677
    Abstract: A control system includes a first vehicle controller configured to be disposed onboard a first vehicle system moving along route segments and to receive a conditional movement authority that has a condition to be met before the first vehicle system can travel into a designated route segment of the route segments. The first vehicle controller is configured to communicate with a separate, second vehicle system to determine a state of the second vehicle system. The first vehicle controller is configured to determine whether the state of the second vehicle system satisfies the condition of the conditional movement authority. The first vehicle controller also is configured to permit movement of the first vehicle system into the designated route segment responsive to determining that the state of the second vehicle system satisfies the condition of the conditional movement authority.

  • Publication number: 20200189629
    Abstract: A system for determining a location of a rail vehicle based on a radio frequency (RF) signal includes at least one processor programmed or configured to receive an RF signal transmitted by at least one radio transmitter device, where the RF signal includes location data associated with the location of the at least one radio transmitter device, determine a location of the at least one radio transmitter device based on the location data associated with the location of the at least one radio transmitter included in the RF signal, and determine a location of a rail vehicle based on the location of the at least one radio transmitter device. A method and computer program product are also disclosed.

  • Publication number: 20200039546
    Abstract: A vehicle control system includes a movement sensor configured to output information indicative of movement of a vehicle system and a controller configured to determine whether the vehicle system has stopped moving based on the information that is output from the movement sensor. The controller is configured to increment a counter based on a length of time that the vehicle system has remained stopped. The controller is configured to control operation of the vehicle system based on the counter that is incremented.

  • Publication number: 20190389498
    Abstract: A system, method, and computer program product for determining ancillary subdivision/districts may include obtaining route data associated with one or more vehicle network operators operating one or more subdivisions/districts over which the vehicle group may travel, determining an ancillary subdivision/district of the one or more subdivisions/districts that are not included in the route data by any of the one or more vehicle network operators, receiving route data for the vehicle network operator associated with the ancillary subdivision/district, and communicating with one or more wayside interface units in the ancillary subdivision/district based on the route data.

  • Publication number: 20190389499
    Abstract: A system, method, and computer program product for determining ancillary subdivision/districts may include obtaining track data associated with one or more railroads operating one or more subdivisions/districts over which the train may travel, determining an ancillary subdivision/district of the one or more subdivisions/districts that are not included in the track data by any of the one or more railroads, receiving track data for the railroad associated with the ancillary subdivision/district, and communicating with one or more wayside interface units in the ancillary subdivision/district based on the track data.

  • Patent number: 10457299
    Abstract: A train control system and method for 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, includes at least one computer programmed or configured to receive or determine an indication that the train is stopped, continuously increment a counter in response to the indication that the train is stopped, and control an operator interface to output a current count of the counter to an operator of the train.

  • Patent number: 9254855
    Abstract: A computer-implemented method for managing conditional authorities in a vehicle network for a target train, including: generating at least one conditional authority for the target train, the at least one conditional authority comprising authority data related to at least one identifying train; establishing at least one direct or indirect communication link between the target train and the at least one identifying train; determining position data for the at least one identifying train; comparing at least a portion of the position data with at least a portion of the authority data; and based at least partially on the comparison, generating at least one indication that the target train is authorized to proceed. Systems for managing conditional authorities in a vehicle network for a target train are also disclosed.

  • Patent number: 9168936
    Abstract: A computer-implemented method of transforming movement authority limits for a train traveling in a track network, which includes determining authority of tracks associated with a switch, based at least partially on authority data and/or train authority data for the train, and providing authority on a switch leg of the switch based at least partially on the authority of the associated tracks. The computer-implemented method also includes determining authority of tracks associated with switches on at least two tracks, based at least partially on authority data and/or train authority data for the train, and providing authority on a crossover track between the at least two tracks based at least partially on the authority of the associated tracks.

  • Patent number: 8478463
    Abstract: A train control system for controlling trains traveling in a track network including tracks with signals associated therewith. The system includes an on-board track database, a positioning system and an on-board control system. The on-board control system receives position data and automatically brakes the train prior to encountering an upcoming signal based upon specified data points. The train is not automatically braked if certain conditions are met. A method for controlling a train traveling in a track network is also disclosed.
