Abstract

A system for identifying at least one condition of at least one upcoming feature of at least one track in a track network. The system includes a positioning system for determining an estimated train position on a track within the track network, and at least one database including track data and feature data. A computer (i) obtains the determined estimated train position on at least one track from the positioning system; and (ii) for the at least one track, identifies at least one condition for at least one upcoming feature based at least in part upon the track data and the feature data in the at least one database. The feature data is dynamically updated while the train is traversing the track in the track network. A method and apparatus for identifying a condition of an upcoming feature are also provided.
