A track identification system for a plurality of locomotives moving on defined plurality of tracks, said tracks having uniquely identifiable switching locations where said locomotives can switch movement from one track to movement on to one or more other tracks, said tracks passing through a railway network consisting of locomotives, stationary structures such as stations, crossings, yards, said system consisting of on board computers fitted to each of the locomotives, said on board computers having storage means to eraseably store digitally encoded information of at least a portion of the route and track data relating to the said plurality of tracks, each of said uniquely identifiable switching locations, and the parameters of movement of the locomotives along the said tracks, said computers having processors programmed to receive reference location signals of the locomotive from a global positioning system and thereby determine the precise geographical locations of the locomotives, said computers further programmed to digitally map at least a portion of the determined geographical locations on the stored route and track data, and to continuously monitor the movement of the locomotives with reference to parameters such as their location coordinates, velocity and angular change profile at the said switching locations, and further having programming means to compute the angular change profile to determine switching actions at the said switching locations and programmed signal generator means operable by the said processing means to generate signals relative to the angular change profile relating to switching actions at the switching locations thereby determining the tracks on which the movement of each of the locomotives is occurring and the velocity of such movement. |
