With first and second wagons (1, 3), including an emitter similar to the one of an access point and a receiving wagon (2), including a receiver similar to the one of a device onboard a train and measuring a quantity relating to a received signal, this method consists of: placing the first wagon at a previous implantation point while the emitter of the first wagon emits a first signal, moving the receiving wagon away from the first wagon; when the quantity relating to the first signal is under a threshold, immobilizing the receiving wagon; while the emitter of the second wagon emits a second signal, moving the second wagon away from the receiving wagon; when the quantity relating to the second signal is under the threshold, immobilizing the second wagon; and storing its position as the implantation point of an access point.

There is described systems and methods for managing an electrical surge of railway signaling equipment. A breaker includes a mechanical reset button that shifts positions in response to detecting the electrical surge exceeding a threshold amperage. An opto-isolator deenergizes in response to the position shift of the mechanical reset button. The event recorder transmits an alarm signal to a remote office system in response to the deenergizing of the opto-isolator.

A communication system includes communication units onboard a vehicle system. A first unit receives satellite positioning data and correction data based on phase measurements of satellite signals. A second unit receives the satellite positioning data. One or more processors determine a first geographical position of the first unit based on the position correction data and the satellite positioning data. The processors communicate the position correction data or a copy thereof to the second unit. The processors determine second geographical position data of the second unit based on the position correction data and the satellite positioning data. The one or more processors communicate the second geographical position data that is determined to the first communication unit.

A wireless terminal configured for use in a mobile vehicle comprises a transmitter (64), a receiver (66), and processor circuitry (42). The transmitter (64) is configured to transmit a series (50) of vehicle data messages (52) over a vehicle (V2X) communication radio interface (15). The receiver (66) is configured to receive a message (56) from a stationary infrastructure unit (36) over the vehicle (V2X) communication radio interface (15). The processor circuitry (42) is configured to: generate the vehicle data messages of the series (50); set a default transmission rate for transmission of at least some of the vehicle data messages of the series; make a determination regarding content of the message received from the stationary infrastructure unit (36); and thereafter in accordance with the determination, set a modified transmission rate for transmission of at least another vehicle data message of the series and thereby modify utilization of the vehicle (V2X) communication radio interface (15).

A method and an apparatus for a train control system are disclosed, and are based on virtualization of train control logic and the use of cloud computing resources. A train control system is configured into two main parts. The first part includes physical elements of the train control system, and the second part includes a virtual train control system that provides the computing resources for the required train control application platforms. The disclosed architecture can be used with various train control technologies, including communications based train control, cab-signaling and fixed block, wayside signal technology. Further, the disclosure describes methodologies to convert cab-signaling and manual operations into distance to go operation.

A system for automatically updating route information to a locomotive that includes a route computer and voice radio encoder that merges data representing temporary changes in a route with a voice radio call placed by a dispatcher to a locomotive engineer. A voice radio decoder coupled to the locomotive cab voice radio extracts the data representing the temporary changes from the voice radio signal and provides the data directed to the energy management system so that there is no need for the engineer to manually enter the temporary data.

Systems and methods are disclosed for reliable detection of oncoming trains and for warning roadway personnel working on the railroad track of the oncoming train. A train detection system includes a wireless communication network further including train detection modules attached to catenary poles along the sides of the railroad track. Each train detection module is equipped with at least two diverse sensors configured to detect trains and other on-track vehicles. Each train detection sensor is simultaneously active and works with other train detection sensors to detect an approaching train and generate train alerts. The train alerts are transmitted wirelessly over the wireless communication network by the train detection modules. The system transmits train alerts to personal alert devices worn by roadway workers. The personal alert device forms an ad-hoc wireless network with the train detection modules.

Systems and methods for protecting and preventing unauthorized transfer or downloading of recorded train event data for use in a train event recording system of a train. A train event recording system and an authenticated data storage device are also disclosed. According to one preferred and non-limiting embodiment, provided is a system for protecting recorded train event data, the system including at least one external memory device having encrypted authentication data stored thereon, the encrypted authentication data including authentication data encrypted with at least one first key.
