    摘要： A wireless position sensing device is provided for monitoring railyard equipment status. The device comprises a gravity sensing mechanism for sensing an angular displacement with respect to a substantially vertical line, and for generating a displacement signal upon sensing a change in angular displacement exceeding approximately 40 degrees. A processing mechanism, operatively coupled to the gravity sensing mechanism, receives the displacement signal. A radio frequency transmitter, responsive to the processing mechanism, transmits a data signal indicative of the angular displacement. The processing mechanism is programmed to activate the radio frequency transmitter upon receipt of the displacement signal. The gravity sensing mechanism is affixed, attached, or mechanically coupled to railyard equipment comprising at least one of a manually operated rail switch or a safety indicator.

    摘要： 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.
