Abstract:
A system and method which may include on each locomotive a propulsion system and a braking system; a transceiver for communication between the locomotives; and sensors for sensing operational conditions on the locomotive. A processor receives the sensed operation conditions, communicates information including the sensed operational conditions to the other locomotive, determines a propulsion or braking value or command based on the sensed operational conditions, pre-selected criteria and the information received from the other locomotive, and outputs the propulsion or braking value or command. The present system may include on each locomotive a location determining device and a storage of track topology; and the processor determines and communicates to the other locomotive as information an initial propulsion or braking value using the topology of the present and projected location of the locomotive and pre-selected criteria, determines a final propulsion or braking value or command based on the initial value and the information received from the other locomotive, and outputs the final propulsion or braking value.
Abstract:

Abstract:
A geographic information System (GIS) displays geographic roadway data, geographic track data and geographic train position data. The GIS includes a GIS database having static roadway and track data. A computer aided dispatching (CAD) System includes a task to determine an occupied track section. A web server includes a first routine determining geographic starting and ending positions of the track section, a second routine displaying geographic information regarding the static roadway and track data. and a third routine determining geographic information regarding the occupied track section from the geographie starting and ending positions of the track section and from the GIS database. A client system communicates with the web server to receive and display the geographie information regarding the static roadway and track data, and to receive and display the geographic information regarding the occupied track section with the geographie information regarding the static roadway and track data.
Abstract:
A method and system (10) for self-directed operation of a locomotive (12) in a rail yard (82) using a control system (64) on the locomotive for controlling locomotive operations. The method includes establishing at least one operational area (e.g. 74, 76, 78) within the rail yard and associating an operational parameter with each area. The method also includes operating the locomotive using the control system and sensing a location of the locomotive within an operational area. The method further includes determining whether the locomotive is operating within the operational parameter established for the area of its location. If the locomotive is determined not to be operating within the operational parameter, an operation of the locomotive is automatically controlled to operate within the respective operational parameter, without operator input to the control system. The system includes a location detector (62) in communication with the control system to automatically control locomotive operation.
Abstract:
A method and system for automatically activating a train warning device that uses a positioning system such as a global positioning system (GPS) receiver or an inertial navigation system (INS) to determine the train's position. The system further includes a database containing locations of grade crossings and other locations at which a train is required to give a warning signal and what regulations govern activation of the warning device at such locations.
Abstract:
A device for determining the position of a rail-bound vehicle (1), comprising at least one sensor (2, 2b) adapted to generate a signal dependent upon irregularities in the track caused by rail components arranged on or in connection to the rail track, a memory means (5) adapted to store information about the position of the rail components along the route of travel of the vehicle and necessary features for identifying the rail components, an identifying means (6) adapted to detect and identify the rail components by comparing said signal with the stored features, a calculating means (7) adapted to determine the position of the vehicle based upon the identified rail components and their stored position. A method to determine the position of a rail-bound vehicle whereby position and characteristic features of rail components arranged on or in connection to the rail track are registered and stored in advance. During a signal dependent upon irregularities caused by said rail components is generated. The signal is compared to the stored characteristic features, whereby the rail components are detected and identified, and the position of the vehicle is determined based upon the identified rail components and their stored position.
Abstract:
A method using the position data being determined on the train to determine characteristics of the track and location of the train. This is achieved by providing position determining devices at two or more spaced locations along the train. The position of the two locations are determined by the position determining devices. A processor determines the difference between the two locations from the positions determined by the position determining devices and determines the characteristics of the track and location of the train from the determined difference between the two locations.
Abstract:
The invention relates to a method for determining the position of a rail vehicle (2) that runs on a system of railroads. A user device that is present in the rail vehicle and that is provided with a receiver and/or transmitter unit contacts at least one accessible communication station (3) of a mobile radio communication system, thereby obtaining a location information. The location information thereby obtained is used to determine the position of the rail vehicle by correlating it with cartographic information about the system of railroads. The inventive system allows to use already existing mobile radio communication systems in combination with already existing, for example vectorial, representations of the system of railroads and is therefore inexpensive and easy to implement.
Abstract:
In one aspect, the present invention relates to identifying locomotive consists within train consists, and determining the order of the locomotives within the identified locomotive consists. By identifying locomotive consists and the order of locomotives within such consists, a railroad can better manage its locomotive fleet. In one exemplary embodiment, an on-board tracking system for being mounted to each locomotive of a train includes locomotive interfaces for interfacing with other systems of the particular locomotive, and a computer coupled to receive inputs from the interface, and a GPS receiver and a satellite communicator (transceiver) coupled to the computer. Generally, the onboard tracking systems determine the absolute position of the locomotive on which it is mounted and additionally, obtain information regarding specific locomotive interfaces that relate to the operational state of the locomotive. Each equipped locomotive operating in the field determines its absolute position and obtains other information independently of other equipped locomotives. Position is represented as a geodetic position, i.e., latitude and longitude. As locomotives provide location and discrete information from the field, a central data processing facility receives the raw locomotive data. The data center processes the locomotive data and determines locomotive consists.
Abstract:
A logistics system (10) and a method are mounted on a vehicle (4) and utilize vehicle position control (8) for logistics operations, such as loading and unloading material to and from the vehicle (4). The position control can be GPS-based and/or based on linear movement of the vehicle (4), such as movement of a railcar (4) along a track (5). A computer-based position control subsystem (8) mounted on the vehicle (4) is connected to and operates vehicle-mounted components (40) for performing the logistics functions.
