Abstract: A method for detecting a movement of a rail vehicle, in particular a freight or passenger train, in a warning zone of a rail crossing, includes: determining a first temperature in the warning zone of the rail crossing or in a portion of the warning zone at a first time; determining a second temperature in the warning zone of the rail crossing or in a portion of the warning zone at a second time. The first time is chronologically before the second time. The method compares the first temperature with the second temperature. If the comparison demonstrates that the second temperature is higher than the first temperature, the method outputs a warning signal and initiates blocking of the rail crossing.

Abstract: A highway grade crossing gate system comprises a gate arm configured to rotate 90 degrees from a horizontal position to a vertical position and vice versa and a highway grade crossing gate mechanism coupled to the gate arm for controlling rotation of the gate arm without mechanical user adjustments but rather use user angle and time inputs/outputs. The highway grade crossing gate mechanism includes a DC motor to drive the gate arm up and down and a voltage reduction circuit to receive an input voltage from a battery and reduce the input voltage. The highway grade crossing gate mechanism further includes a human machine interface (HMI) to receive a plurality of programmable set points as operational variables for operation of the gate arm without manually adjustable cams on a main shaft that move contacts to open or close at some preset angular rotation. The highway grade crossing gate mechanism further includes a control printed circuit board (PCB) coupled to the HMI, the voltage reduction circuit, the brake, and the DC motor. The control PCB to receive an output based on an angular position of the gate arm as a position indication to have the control PCB provide an output for the operation of the gate arm.

Abstract: A system for simulating a railroad track. The system comprises one or more modular track simulation units that are smaller than conventional track simulators and are easy to use with and be connected to a device being tested (e.g., grade crossing predictor). Each track simulation unit may have one of a plurality of impedances associated with a corresponding railroad track length. The units are combinable such that the system can simulate multiple, different track lengths. Each unit has a plurality of test points that can be connected to the device under test and/or used to alter conditions of the simulated track.

Abstract: Systems and methods for detecting the dynamic train-to-rail shunting performance of a train as it is moving along the rails of a railroad track. The systems and methods use portable equipment temporarily installed at a site where it is desired to test the shunting of one or more trains or the electrical equipment installed at the track. The systems and method use sensor plates and a high speed recording system to simultaneously capture measured train-to-rail shunting characteristics and the positioning of a train's axles and any rail conditions impacting the measurements. The captured information can be used to fine tune the train, the electrical equipment installed at the track and/or to design new devices.
