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 system and a method for monitoring route devices in a transportation network includes one or more processors to receive sensed traffic control device information from first vehicle systems in a transportation network formed from interconnected routes. The sensed traffic control device information indicates states of traffic control devised at intersections between the routes in the transportation network. The one or more processors determine whether the sensed traffic control device information conflicts with stored traffic control device information stored in a database accessible by the one or more processors. The one or more processors send one or more bulletins to one or more second vehicle systems to change movement of the one or more second vehicle systems responsive to determining that the sensed traffic control device information conflicts with the stored traffic control device information.

System and method for monitoring traffic control devices

A switch reporting device including at least one display screen, a high resolution camera, a code reader, at least one memory and one or more processors, the switch reporting device configured to determine a position of an unmonitored switch in a railway by capturing an image of one or more portions associated with the unmonitored switch, generating switch position data based on the image of one or more portions associated with the unmonitored switch, and updating a switch position record for the unmonitored switch with the switch position data. The switch reporting device includes one or more mobile computers or an EOT device for monitoring and reporting switch position data for an unmonitored switch.
