Publication number: 20120029740Abstract: A method and a corresponding device enable monitoring the speed of rail vehicles. In order to enable a reduction and simplification of the required system components and a speed monitoring that is not only intermittent, it is provided that the rail vehicle emits a signal, the propagation time of which is evaluated on the track side with regard to the speed. The evaluated signal is transmitted back to the rail vehicle.Type: ApplicationFiled: March 30, 2010Publication date: February 2, 2012Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Ulrich Bock, Bernhard Evers, Lars Schnieder

Patent number: 8095253Abstract: A fuel efficiency improvement device for use on each of a plurality of locomotives in a consist includes a processor configured to transmit an initialization message including an identifier and power and fuel consumption rate information for the locomotive on which it is installed to all other locomotives in the consist. One of the devices is chosen to act as a lead device. The lead device is responsible for determining alternative throttle notch settings for each of the locomotives based on the power and fuel consumption rate information in the initialization message. The lead device may be chosen on the basis of identifiers in the initialization messages such as serial numbers. The alternative throttle settings may be determined using greedy value and maximum power calculations.Type: GrantFiled: July 24, 2008Date of Patent: January 10, 2012Assignee: Invensys Rail CorporationInventors: Mark Edward Kane, John D. Mix, Mark M. Madden

Patent number: 8090486Abstract: A method for delivering and maintaining mandatory directives data from a central office server to an on-board system. Mandatory directives include the enforceable train control data required for a train operating on controlled track. The method enables the on-board system and the central server to exchange data in a vital manner, in part by checking for any inconsistency between i) the on-board system's data as previously transmitted and ii) the required data as represented by both a transmitted set of data identifiers and an associated error correction code.Type: GrantFiled: January 20, 2009Date of Patent: January 3, 2012Assignee: Lockheed Martin CorporationInventors: Gerhard F. Meyer, Richard A. Allshouse, Robert B. Groves, Jr.

Patent number: 8065045Abstract: A system which operates a digitally controlled model railroad transmitting a first command from a first client program to a resident external controlling interface through a first communications transport. A second command is transmitted from a second client program to the resident external controlling interface through a second communications transport. The first command and the second command are received by the resident external controlling interface which queues the first and second commands. The resident external controlling interface sends third and fourth commands representative of the first and second commands, respectively, to a digital command station for execution on the digitally controlled model railroad.Type: GrantFiled: November 4, 2010Date of Patent: November 22, 2011Inventor: Matthew A. Katzer

Publication number: 20110270475Abstract: Systems and methods are described for monitoring different conditions that are simultaneously or concurrently experienced by different vehicles in the same consist and using the monitored conditions to locally change operations of one or more of the vehicles. In accordance with one embodiment, operations data related to one or more vehicles of the consist is acquired from one or more of plural different locations in the consist. The operations data and location data related to where the operations data is acquired are communicated to a first vehicle of the consist. Command data is formed based on the operations data and the location data. The command data directs at least one of the vehicles in the consist to change one or more operations of the at least one of the vehicles. The command data is transmitted to one or more of the vehicles of the consist.Type: ApplicationFiled: July 15, 2011Publication date: November 3, 2011Inventors: John BRAND, Jared COOPER, Wolfgang DAUM, Daniel BALLESTY

Patent number: 8036784Abstract: A system for verifying the integrity of a train having a predetermined length is provided. The system includes a device for communicating and synchronizing with a detector of a circuit. The detector detects the presence/absence of a train. The device also includes an odometer providing an odometric reference at the start of occupation of the circuit and when the circuit is left by the train, a first processor calculating the distance traveled by the train on the basis of the difference between the two odometric references, a second processor calculating a minimum estimate of the length of the train that is equal to the calculated distance traveled less the algebraic length of the detection circuit and an information mechanism indicating that the train is integral when the calculated length of the train is greater than the predetermined length of the train less the length of a wagon. A method and a computer program product are also provided.Type: GrantFiled: February 1, 2010Date of Patent: October 11, 2011Assignee: Alstom Belgium S.A.Inventors: Jean-Pierre Franckart, Eric Lechevin
