Abstract
A GPS based system for automatically controlling the travel and other operational functions of a train. The system stores data characteristic of each location long the track such as speed limits, rail crossing locations and station locations. GPS input data provide information as to the current geographic coordinates of the train. If action is necessary such as slowing to conform with speed limits, sounding the horn as a crossing is approached, or announcing the approach to a train station, the system automatically takes the indicated action. Each train transmits its current location to other trains in the vicinity via satellite. An override allows a human operation to intervene and operate the train if necessary.
