ABSTRACT:
Methods and systems for monitoring trains in a railyard. These methods and systems detect an incoming train entering a geographic area defined by a railyard, store an entry time indicative of a time at which the incoming train entering the railyard was detected, detect the incoming train coming to a stop in a subyard of the railyard, store a stop time indicative of a time at which the incoming train came to a stop in the receiving subyard, calculate an incoming train latency time by subtracting the entry time from the stop time, and store the incoming train latency time as an incoming train latency time record.
