A train control network includes a rail, a first communication element and a second communication element, which are to communicate with each other. The first communication element includes a first HF-injector, adapted for injecting HF-signals into the rail. The second communication element includes a HF-receiver, adapted for receiving HF-signals transmitted via the rail. An evaluation unit is provided for analyzing the received HF-signals.

A method of determining when a first train has cleared an intersection a distance to permit travel of a second train through the intersection without risk of collision or contact includes: (a) sampling first GPS data corresponding to a location of a lead vehicle of the first train travelling on a first track when the lead vehicle passes proximate a marker; (b) sampling second GPS data corresponding to a location of a last vehicle of the first train moving on the first track; (c) comparing the second GPS data and the first GPS data: (d) repeating steps (b)-(c) until the location corresponding to the first GPS data and the location corresponding to the second GPS data are within a predetermined distance of each other, and (e) generating a signal when the locations are within the predetermined distance.

A system for testing trainline communications includes a command test box, a remote test box, and a controller. The command test box is coupled to a first electric coupler at a first end of a consist including one or more cars of a railroad train. The command test box applies a test signal to the first electric coupler and wirelessly transmits an indication of the test signal. The remote test box is coupled to a second electric coupler at a second end of the consist, and determines whether the test signal is present at the second electric coupler and wirelessly transmits an indication of the test signal. The controller communicates wirelessly with the test boxes to determine whether the test signal has successfully traversed the consist.

A method for wagon-to-wagon communication between wagons of a train is disclosed. The train includes a first train wagon and at least one further train wagon, the first train wagon having a first transmitter/receiver device, and the further train wagon having a further transmitter/receiver device. The first transmitter/receiver device sends a request message using short distance communication. The further transmitter/receiver device sends an acknowledgement to the first transmitter/receiver device using short distance communication. The first transmitter/receiver device sends a first identification code identifying the first train wagon to the further train wagon. A method for checking train integrity and a train wagon is also disclosed.

A system and method for monitoring a track and/or rail employs one or more imagers mounted to a railcar and directed to image the track and/or rails wherein the images are geo-tagged with location data. Geo-tagged images are processed to determine at least track gauge and/or at least rail fastener integrity. The system and method may also determine other track and/or rail integrity issues including, e.g., rail fastener integrity, rail profile, rail alignment, center point dip, cross level, rail cant, wheel wear, wheel integrity, rail wear, rail defects, and/or rail temperature. The system and method may also determine when inspection and/or maintenance of the track is indicated, and provide selected records of where and/or when such inspection and/or maintenance is indicated.

A system that allows an electronically controlled pneumatic (ECP) railcar to be optionally selected as the ECP End of Train (EOT) device when that car is positioned at the end of a train regardless of its physical orientation. This eliminates the requirement to use and install a traditional End of Train (EOT) device at the end of an ECP train while maintaining the same train integrity monitoring functionality that is typically provided for train brake-in-two detection and closed cut-out cock detection. The system also eliminates the requirement for a dedicated EOT device at the end of the train for ECP RUN Mode operation, and allows any ECP car to function normally as part of the train or act as the EOT device when selected.

An end of train (EOT) system includes monitoring equipment with a sensor to monitor a pressure of air in a brake mechanism in a railcar, and a power supply having battery cells and a temperature control system for the battery cells. The temperature control system includes a heat sink in heat transference contact with the battery cells, and an electronically controlled heater for the battery cells. The temperature control system includes a temperature sensor, and a control device coupled with the temperature sensor and the electronically controlled heater to vary an output of the heater based on an output of the temperature sensor.

A device for attachment to a train having a lead locomotive or control car and a rear car in a track network having a plurality of tracks is disclosed. The device may include at least one sensor. The sensor(s) may be disposed with the rear car. The sensor(s) may be configured to generate sensor data associated with at least one of a heading of the rear car of the train or a distance between the rear car of the train and an object in the track network. A communication interface may be configured to transmit the sensor data to at least one receiver. The receiver(s) may provide at least one indication based on the sensor data. A device for use onboard the train, a control system, a method for operating the device(s), and a method for coupling the train to a separate car are also disclosed.

In a method of controlling operation of an end-of-train unit (EOTU) of a train during travel of the train on a path, a GPS receiver of the EOTU receives first GPS data and a controller, based on the received first GPS data, sets an electrical/electronic device or system of the EOTU to a first mode of operation. After travel of the train on the path following setting the electrical/electronic device or system to the first mode of operation, the GPS receiver receives second GPS data. The controller, based on the received second GPS data, sets the electrical/electronic device or system of the EOTU to a second, different mode of operation.

A system for determining a location of a rail vehicle based on an radio frequency (RF) signal that includes at least one processor programmed or configured to determine that a first RF communication signal transmitted by a head of train (HOT) unit of a plurality of rail vehicles is received by an end of train (EOT) unit of the plurality of rail vehicles, determine whether a second RF communication signal transmitted by the HOT unit is received by the EOT unit during a time interval after a time at which the first RF communication signal was determined to be received by the EOT unit, and determine one or more locations of the plurality of rail vehicles based on determining that the second RF communication signal transmitted by the HOT unit is not received by the EOT unit during the time interval. A method and computer program product are also disclosed.
