Abstract
A system determines real-time locations of railcars in a railroad environment. Railcars are equipped with at least four RFID tags. A RFID reader at a fixed location at every track branch in the environment reads the RFID tags. Railcar locations are updated for the railcars by determining the branches on which the railcars are located.
