Various methods and systems are provided for a vehicle. In one example, a vehicle comprises a first fuel tank configured to store a first fuel, and a second fuel tank configured to store a second fuel, both the first fuel tank and the second fuel tank disposed in the vehicle, a multi fuel engine disposed in the vehicle, the multi fuel engine configured to combust the first fuel and the second fuel, a fuel injection system configured to inject the first fuel into the multi fuel engine, and a conduit configured to route the second fuel from the second fuel tank to the multi fuel engine.

Systems and methods for modulating a telepowering signal in a downlink communication. Embodiments of the present invention provide a fingerprint module to generate a fingerprint signal that can be modulated with a telepowering signal for communication by a transmission module in a downlink communication. The fingerprint signal is reflected by a wayside equipment module and received by the transmission module to enable an additional communication other than the downlink communication and an uplink communication.

Systems and methods are provided for train operation control and enforcement. A train control system for controlling operations of a train may include a train-mounted control unit deployed in the train, and a plurality of fixed control nodes deployed on or in close proximity to a track traversed by the train. Each of the train-mounted control unit and fixed control nodes includes a corresponding communication subsystem that includes transponders and communication circuits, configured for communicating signals. The train-mounted control unit is configured to transmit signals to and receive signals from the plurality of fixed control nodes, with the signals including ultra-wideband (UWB) signals and with at least some of the signals carrying data pertinent to controlling operations of the train; and to determine control information relating to controlling operations of the train based on received UWB signals originating from one or more fixed control nodes.

A vehicle control system and method includes a first controller that controls operation of a first vehicle and is operably coupled with a first communication system. A second controller controls operation of a second vehicle and is operably coupled with a second communication system. The first controller determines an orientation of the second vehicle and identifies a type of the second vehicle. The first controller generates a first set of vehicle control signals based on the orientation and the type of the second vehicle. The first communication system communicates the first set of vehicle control signals with the second communication system. The first controller overrides control of the second vehicle by the second controller to control operation of the first vehicle and the second vehicle according to the first set of vehicle control signals.

A method for locating a rail vehicle with a rail vehicle position determination device on a route includes reading positions of reference marks, passed by the rail vehicle, along the route of the rail vehicle and evaluating additional distance information. In order to locate a rail vehicle with little expenditure and with comparatively high accuracy, in the case of a route with at least one track section bounded by axle counting sensor units and having an axle counting evaluator, information on the number of axles from the axle counting evaluator is transferred to the rail vehicle position determination device for determining the position of a rail vehicle. In the rail vehicle position determination device, the position of an axle of the rail vehicle corresponding to the information on the number of axles is determined using route topology data present there, and this position is used as a further reference mark.

A method operates an automatic train control system which has an electronic signal box, a balize and a frequency track circuit. To configure the train control system so as to be constructed from components of the European train control system and of the frequency track circuit without substantial additional development effort, the balize is acted upon by indicator messages of a first type of the electronic signal box via an actuation module for modular elements having an addressable memory for the number of currently free block route segments. Indicator messages of a third type are created from indicator messages of a second type. A functional relationship between the addresses of the memory and code information of the frequency track circuit is taken into account during the creation of the third indicator messages. A transmitter of the frequency track circuit is acted upon as a result of the third indicator messages.

A portable mounting assembly is provided comprising a mounting disc comprising at least one magnetic component for attaching the mounting disc to an axle bearing on a vehicle such as a locomotive, for determining speed; and a stabilizer bar attached at a first end to the mounting disc and at a second end to an outrigger comprising at least one magnetic component for attaching to a stationary component of the vehicle. A method of providing speed control to a portable remote control system for a locomotive is also provided. A method of overriding a speed control mode operated by a portable remote control system for a locomotive is also provided.

The present invention relates to a train control device. The train control device sets an emergency brake pattern and a regular brake pattern as patterns of maximum speed according to the distance to a stopping point, and outputs a braking command when the train speed exceeds the maximum speed. Then, when the maximum speed defined in the regular brake pattern falls below a set speed, the maximum speed of the regular brake pattern is kept constant for a predetermined distance. After that, the maximum speed is gradually reduced toward a stopping point of the emergency brake pattern. This allows a train to make an approach to a fixed stopping position in an automatic train operation even when the fixed stopping position is located farther than a stopping point of the regular brake pattern, and excessive output of an emergency braking command based on the emergency brake pattern can be reduced.

A ground control device includes a control unit that determines a control mode of operation control on a train in a communication area of a radio communication apparatus, based on information on a communication level indicating a communication state between the train and the radio communication apparatus determined in a predetermined period, and performs train operation control according to the determined control mode on a train entering or approaching the communication area after the control mode is determined, and a storage unit that stores one or more pieces of the information on the communication level on one or more of the radio communication apparatuses.

A transportation system is provided. The system includes: a highway vehicle, a first set of highway points located along a path of the vehicle, a second set of highway points located along a traffic signal section, at least one RFID tag located at each of the first set and the second set of highway points, and at least one RFID tag reader located on the highway vehicle connected to a network. The at least one RFID tag located at the first set of highway points is configured to store dynamic and static characteristics of the highway vehicle as it passes the first set of highway points and the at least one RFID tag located at the second set of highway points is configured to store dynamic and static characteristics of the vehicle as it passes the second set of highway points.
