A track identification system for a plurality of locomotives moving on defined plurality of tracks of a railway network wherein the system consists of on board computers with track data and identifiable switching locations data and the parameters of movement of the locomotives along the said tracks, the computers receiving reference location signals of the locomotive from a global positioning system and different geographical locations of the locomotives and digitally map the determined geographical locations on the stored route and track data, the computers continuously monitoring the movement of the locomotives with reference to specific parameters to compute the angular velocity change profile to determine switching actions at the said switching locations and generate signals relative to the angular change profile relating to switching actions at the switching locations to determine the tracks on which the movement of each of the locomotives is occurring and the velocity of such movement.
