An operation status reproducing device includes an onboard information obtaining unit that obtains onboard information corresponding to date and time from an onboard device mounted on a designated train being a train specified by a train number and the date and time externally designated, a specific event detecting unit that specifies time at which a specific event occurs by analyzing the onboard information, a ground information obtaining unit that obtains ground information in a certain period including the time at which the specific event occurs from a ground device, an external information obtaining unit that obtains external information including weather information in a certain period including the time at which the specific event occurs, and a reproduction image generating unit that generates a reproduction image illustrating a past operation status of the designated train based on the onboard information, the ground information, and the external information.

A method for outputting a trigger signal for an acoustic warning signal of a rail vehicle, includes reading in a piece of signal information detected by an image sensor of the rail vehicle, comparing the piece of signal information to at least one stored piece of reference signal information to classify the piece of signal information as a warning sign requiring an output of an acoustic warning signal, and providing a trigger signal to an output unit of the rail vehicle for outputting an acoustic warning signal.

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.

The present invention relates to a method for sending information to an individual (11) located in the environment of a vehicle (10), the method comprising the following steps: acquiring an image of the environment of the vehicle (10), detecting, where applicable, at least one individual (11) on the acquired image, determining a probability of collision between the individual (11) detected on the acquired image and the vehicle (10), sending at least one item of information to the detected individual (11), the information sent depending on the determined probability of collision, the steps of detecting, determining and sending being repeated, for the same individual (11), with subsequent acquired images as long as said individual (11) is detected on said images and as long as the probability of collision is greater than a threshold.

A system and method are for controlling a train traveling along track blocks. A first signal transmitter is installed at a first track block and transmits, using a predefined range of transmission frequencies, first signals for detecting when the train enters the first track block. A second signal transmitter is installed at an adjacent second track block and transmits, using a predefined range of transmission frequencies different from the predefined range of transmission frequencies used by the first signal transmitter, second signals for detecting when the train enters the second track block. One or more signal receivers on board of the train are configured to receive the transmitted first and second signals, and an onboard controller is configured, based on signals supplied by the one or more receivers indicative of the first and second signals received, to identify when the train enters the first or second track blocks.

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.

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.
