The first and second terminals to provide an electric energy source based on the heat extracted and harnessed for powering at least one of an electronic circuit, a light source, and a communication device associated with railways infrastructure.

TRAIN SAFETY WARNING SYSTEM
20170197644 · 2017-07-13 ·

A system for providing train safety warnings can include a train vehicle positioned on and movable along a track, as well as a warning device. The warning device can be associated with a receiving device that is in signal communication with a transmitter, such as a transmitter included on the train vehicle. An emitter of the warning device is configured to output an indication that the train vehicle is approaching based on the signal communication with the transmitter. In some instances, the warning device, and/or the emitter thereof, can be positioned at a same elevation as the track.

BOND PIN ASSEMBLY FOR CONNECTING CONNECTION CABLES
20170158083 · 2017-06-08 ·

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.

Railroad switch device for moving railroad switch points
12221144 · 2025-02-11 ·

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.

Train control device

A train control device includes an on-vehicle base station mounted on a train, base stations that can communicate with the on-vehicle base station, an on-vehicle control device controlling an operation such that the train can stop before reaching a stop limit before which the train can run safely, and ground control devices that transmit, to the train side, the stop limit calculated based on information on the current position acquired from the train side via the base stations and opening information on a turnout on the ground. The on-vehicle control device calculates a channel-reservation start pattern, which is a pattern determining a reservation start position of a communication channel of a base station as a switching target when the base station as a communication partner to the on-vehicle base station is switched and in which the reservation start position is different according to train speed and train position.

Train direction and route detection via wireless sensors
09630635 · 2017-04-25 · ·

Systems and methods for detecting train direction and route along a railroad track. The systems and methods use wireless train presence detection sensors such as e.g., magnetometer sensors to detect the presence of the train, and its direction and route along the track.

Standstill determination in a rail vehicle

A control arrangement for a rail vehicle, having at least one control device which is or can be connected for the purpose of receiving sensor signals, wherein the sensor signals each represent at least one speed, and having at least one bus connection which is used or can be used to connect the control device to a data bus of the rail vehicle for interchanging data. The control device creates a standstill signal on the basis of the sensor signals and transmits the standstill signal onto the data bus. Also disclosed is a standstill determination device which can receive standstill signals via the data bus, wherein the standstill determination device determines, on the basis of standstill signals received via the data bus, whether the rail vehicle is at a standstill. Also disclosed is a rail vehicle and a method for determining a standstill of a rail vehicle.

System and method for controlling a train travelling along a railway line

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.
