A hazardous event alert system for a train includes a sensor, a communication device, a positioning system, and a computer. The sensor is positioned on or associated with the train and configured to sense or monitor at least one parameter or condition. The computer is programmed or configured to determine that a hazardous event occurred based at least partially on data generated by the at least one sensor, determine or receive the location or position of the at least a portion of the train from the at least one positioning system, generate a hazardous event notification based at least partially on the at least one condition and the location or position of the at least a portion of the train, and communicate the hazardous event notification to at least one of a back office system and at least one remote server associated with at least one specified entity.

Systems and methods are provided for decentralized train control. A decentralized train system may include a plurality of wayside control units, configured for placement on or near tracks in a railway network, and one or more train-mounted units, each of which being configured for use in a particular train. Each wayside control unit may obtain information corresponding to each train that passes within its communication range, and provide obtained train-related information to each train-mounted unit passing within its communication range. Each train-mounted unit may configured to receive train-related information from each wayside control unit that comes within its communication range, process the received train-related information, assess based on the processing of the train-related information conditions relating to operation of train within the railway network, and when at least one condition meets one or more particular criteria, perform or cause performing one or more responsive actions.

A travelling vehicle includes a body including a small marker and a large marker, an imager, a pattern recognizer, and a state determiner. The large marker includes a display pattern including a first region, a second region with a lower reflectance than a reflectance of the first region, and a region where the small marker is located. The small marker has a display pattern including a third region with a lower reflectance than the reflectance of the first region and a fourth region with a lower reflectance than the reflectance of the third region and a lower reflectance than the reflectance of the second region.

An authentication system includes: an electronic key that transmits a signal including authority information indicating authority given to an owner and an authentication key; a plurality of on-board stations installed on a train to receive the signal from the electronic key; and an authentication device that determines a position of the electronic key from a reception status of the signal including the same authentication key in the plurality of on-board stations, and determines, on the basis of the position of the electronic key and the authority information, whether to permit departure of the train and whether to permit operation of a control console of the train.

An anti-collision system for railcars and locomotives and, more particularly, to a distance ranging and worker coupling protection system utilizes remote-sensing radar techniques for use with a locomotive and railcar. The anti-collision system may include an object detector device attached to a railcar or a locomotive that detects objects in a path of the railcar and the locomotive and a train display device electrically connected to the object detector device. The anti-collision system may also include an emergency action device which enables a crew member to stop the railcar or locomotive without communication to a locomotive operator when a hazard is recognized. The object detector device may include a remote sensor, a radio, and a microprocessor programmed to include data-logging to record and log all data from the anti-collision system.

A system for monitoring a useful life of an insulation component of a braking resistor includes a sensor that can be embedded below an outer surface of the insulation component to measure a temperature of the insulation component; and a controller connected to receive a signal from the sensor indicative of the measured temperature of the insulation component, and programmed to compare the measured temperature of the insulation component to a predetermined threshold activation temperature for the insulation component, decrement from a predetermined useful life value for the insulation component a life depreciation value assigned to the measured temperature to determine a remaining life value of the insulation component if the measured temperature of the insulation component is greater than the threshold activation temperature, compare the remaining life value to an end-of-life value for the insulation component, and generate a warning signal if the remaining life value is at or below the end-of-life value.

The object detector device may include a remote sensor, a radio, and a microprocessor programmed to include data-logging to record and log all data from the anti-collision system.

A system and method for detecting the operational status of a brake system on a railcar. The system receives from a sensor an indication of the magnitude of a braking force applied by the braking system in response to an instruction to increase or decrease the braking force. It compares the response to possible responses of the braking system in view of the instruction provided. Based on the comparison, the system generates at least one of a message and/or an alert indicating the status of the brake system. Additional sensors, including a pressure sensor on a brake pipe of the railcar, can be added for additional functionality.

The vehicle monitoring system includes a plurality of cameras provided corresponding to a plurality of doors provided on both sides (A side and B side) of each vehicle, and a management device for determining a camera corresponding to an open door. The management device determines a camera whose initial position is on the B side as the display use camera to be used for display, with respect to a vehicle in which the initial position of the door open camera corresponding to the open door identified by the open door identification information, and the door opening-side information match with the B side. With respect to a vehicle in which the initial position of the door open camera and the door opening-side information do not match with the B side, the management device determines a camera whose initial position is on the A side as the display use camera.

Systems and methods are provided for generating a safety notification to a first train with respect to a speed of a second train along a track, the system including a camera transceiver, comprising a light emitter configured to emit a narrow bandwidth light, an image sensor, one or more light reflectors and a lens subsystem; and a processor configured to perform the steps of: determining a train speed and a train position; receiving images from the camera transceiver; processing the images to calculate a speed and a position of a potential obstacle on the track; responsively to calculating the potential obstacle speed and position, determining a safe speed of the train and providing a control signal to control the first train.
