摘要： Disclosed is a railroad switch device for moving railroad switch points. The device includes two spring assembly sets placed over two switch operation rods. The spring assembly sets move railroad switch points and keep railroad switch points against a stock rail. At least one sensor is mounted adjacent to two switch operation rods. The switch operation rods have a switch point position target connected to the switch operation rods. The switch point position target follows a movement of two throw rods. The two spring assembly sets provide a spring holding force to the two switch operation rods. The spring holding force provides a safe operation of a switch point position assembly by at least one of determining that the spring holding force is present in the moving railroad switch point, and pushing the spring holding force towards the switch point position assembly away from the at least one sensor.

摘要： The present invention relates to methods of improving the reliability and accuracy of level crossing warning systems. The invention is comprised of an axle counter based system that detects the presence and calculates the speed of a train approaching a level crossing and adjusts the activation time for any warning system using a pre-defined period.

摘要： A railroad crossing warning circuit includes a lamp and a signal generator for generating a first signal of a selected frequency. Divider circuitry divides the frequency of the signal to generate second signal at a flashing frequency. A switch responsive to the second signal controls current flow through the lamp and cause the lamp to flash at the flashing frequency.

摘要： A bond pin assembly for connecting a connection cable with a rail, comprising: a bond pin that is inserted into a through hole in the rail, said bond pin having a transition portion and a screw portion, a diameter of one end of the transition portion being larger than a diameter of the other end of the transition portion, the end of the transition portion having a smaller diameter being connected with the screw portion; a conductive sleeve that is provided between the bond pin and a wall of the through hole of the rail, and a nut that is screwed on the screw portion to fasten an end of the connection cable between the nut and a side wall of the rail. By inserting the conductive sleeve with the shape corresponding to those of the through hole and the bond pin between the through hole and the bond pin and further taking fastening measure, the structural intensity of the bond bin assembly can be increased effectively.

摘要： Systems and methods for detecting in motion railcar seismic data generated by defective railcar axles of a train traveling on a track. The method uses two or more seismic sensors on the side of the track to capture seismic noise generated by railcar wheels. A wheel that exceeds a preset seismic noise threshold in amplitude, will trigger a wheel tracking algorithm that calculates seismic phase shift data related to the actively tracked wheel noise level, to determine the precise location, in real time, of the faulty wheel carriage while moving. Knowing the precise location of the tracked wheel allows the system to isolate the railcar and capture the railcar and wheel carriage identification information.Subsequently, a railcar log is made on a computer database with the railcar identification information and made available to control centers via ground or satellite links.

摘要： 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.

摘要： An active fixed block track circuit comprises at least a fixed block section, comprising at least two rails corresponding to each other, each having an isolation connector at two ends thereof and connected to a power supply unit and a traffic signal; a short driving unit, connected to each of the two rails within the fixed block section; and a detection unit, connected to the short driving unit. In this manner, not only the previous rail traffic signal circuit function where no more than one train may be allowed into the same fixed block section is maintained, but also another train approaching from the rear may be prevented from entering the fixed block section when the detection unit at the fixed block section detects an exceptional case happening at a neighboring fixed block section so that the traffic signal unit is switched into a stop traffic signal.
