Abstract
A method includes generating PTC data for at least a portion of a track network, the PTC data comprising real-time train data generated by an on-board system of a train traveling in the track network, the real-time train data comprising a train speed and a train location, generating predictive train location data based at least partially on the PTC data, the predictive train location data comprising at least one upcoming location of the train associated with at least one time; and transmitting at least a portion of the predictive train location data to at least one navigation service in response to receiving a request, the request comprising at least one of the following: a route, an intersection, a rail crossing, geographic coordinates, or any combination thereof.
