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.

Method for obtaining route and directive data for interlocked subdivisions

A computer-implemented method is provided that includes obtaining a first secret and a first public key, and obtaining a second secret a second public key. The method may also include authenticating the first public key of the first vehicle based on a first private key associated with the first vehicle, and authenticating the second public key of the second vehicle based on a second private key associated with the second vehicle. The method may also include preventing a man-in-the-middle attack, by securing at least one of a first vehicle-to-central office communication, a central office-to-first vehicle communication, or a first vehicle-to-second vehicle, wherein the first vehicle-to-central office communication and the central office-to-first vehicle communication are authenticated based on a determined private key associated with a respective first vehicle on-board computer, and sending a message, with the central office server, to a vehicle associated with a conditional movement authority.

Secure vehicle to vehicle PTC communication

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.

Control system for enforcing conditional authorities using vehicle-to-vehicle monitoring

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.

Method and system for vehicle data communication

A system and method for a secure key exchange between two trains operating within a track network may include generating a first or second public key based on a secret random number, generating a shared secret key based on the first or second public key, authenticating one or more key exchange communications by a remote server based on a digital signature established with an on-board key associated with the first train, authenticating a communication by a remote server based on the digital signature of the second train signed with an on-board key associated with the second train, and establishing secure train-to-train communication between the two trains by generating a shared secret key based on a public key received from the other train, the secure key exchange protecting the two trains from a man-in-the-middle attack.

Secure vehicle to vehicle communication

A computer-implemented method for a plurality of trains, at least one of which is operating at a restricted speed, the method including: (a) transmitting, by at least one on-board computer of at least one train to at least one remote server, train location data; (b) requesting, by the at least one on-board computer from the at least one remote server, office polling data; (c) generating at least one poll registration message based at least partially on the office polling data; (d) based at least partially on the office polling data and/or the poll registration message, determining proximity of the at least one train to at least one subdivision; and (e) based at least partially on at least one of the following: train location data, office polling data, the poll registration message, or any combination thereof, transmitting, by the at least one remote server to at least one on-board computer of at least one train, train location data comprising location or position data related to at least one other train. A protection system for a plurality of trains, at least one of which is operating at a restricted speed, is also disclosed.

Method and protection system for trains operating at restricted speed

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.
