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.
Claims15
A method of determining a characteristic associated with a train traveling on a railroad track, said method comprising:
- capturing images of a portion of a train as the train is traveling over first and second sensor plates respectively installed on first and second rails of the track;
- and
- simultaneously capturing measurements of the characteristic as the train is traveling over the first and second sensor plates,
- wherein the characteristic comprises a train-to-rail shunt impedance.
A method of determining a characteristic associated with a train traveling on a railroad track, said method comprising:
- capturing images of a portion of a train as the train is traveling over first and second sensor plates respectively installed on first and second rails of the track;
- and
- simultaneously capturing measurements of the characteristic as the train is traveling over the first and second sensor plates,
- wherein the captured images and the simultaneously captured measurements are correlated and used to fine tune a shunting characteristic of the train.
