  • Publication number: 20100043667
    Abstract: A method is described for operation of a magnetic levitation railway which contains vehicles with a plurality of supporting magnets (20a . . . 20j) and supporting runners (26) associated with them. In the event of a malfunction, the braking of the vehicle with the drive and braking systems switched off is brought about or assisted until a preselected destination stopping point is reached solely in that, even before the destination stopping point is reached, at least one of the supporting magnets (for example 20f, 20g) is switched off, and the magnetic levitation vehicle is placed on the track path (3) by means of the associated supporting runner (26), and is brought to rest at the destination stopping point by making use of the friction forces that occur as a result. The invention also relates to a magnetic levitation vehicle operated in this way.

  • Patent number: 7664459
    Abstract: A distributed power train (10) communications system for sending and receiving signals between a lead locomotive (14) and remote locomotives (12A/12B/12C) in the train (10). A lead (14) initiated message is received by at least the remote locomotive (12A/12B) nearest to the lead unit (14). The receiving remote unit (12A/12B) retransmits the message for receiving by the next remote unit (12C) in the train. Thus the message leapfrogs down the train from the lead unit (14) to the remote units (12A/12B/12C). When the last remote unit (the nth remote unit) (12C) receives the message, the last remote (12C) transmits a status or other response message to the lead unit's message. The status message is received at the (n-1)th remote unit (12A/12B), which appends its status message and transmits the combined status messages toward the lead unit (14).

    Abstract: A remote control system for controlling movement of a train comprises one or more sensors positioned relative to a railroad track for detecting the presence of a lead railcar on the track being pushed by a remotely controllable locomotive. The one or more sensors are spaced a distance from a predetermined stop location of a lead railcar and transmit signals when the lead railcar is detected on the track. A programmable controller positioned off-board or wayside receives signals from the one or more sensors and is in radio communication with an onboard operating system of the locomotive. The controller transmits a signal to the locomotive when the lead railcar is detected by a sensor, and in response to the signal the operating system of the locomotive sets a maximum speed setting for the locomotive to travel on the track toward the stop location.

  • Publication number: 20090072096
    Abstract: The invention relates to a method for controlling train formation in marshalling yards. The control method according to the invention optimises the performance of a marshalling yard by a learning effect based on feed-back. The intervals of time between gravity humps are selected very long on commencement of use of the control system, and data are collected by the gravity humps. A computer determines from the time intervals that occur in these gravity humps in the critical zones of the marshalling yard whether the time interval between push-offs on the hump in the yard may or may not be reduced. The advantage of such a self-learning system is that it requires a much smaller number of programs than conventional systems, which are based on rigid algorithms and the measurement of many factors, and which still remain rigid despite all efforts to record all the influences. The maintenance cost is also considerably reduced.

  • Publication number: 20080154451
    Abstract: A train is driven by drive stations positioned along a track for frictionally contacting side plates on the train. The drive speed is controlled in response to sensors located at each drive station sensing a position of a wheel and a side plate for confirming a presence of the train. A start command is transmitted from the drive station driving the train to a second drive station downstream when a lead car is within a preselected distance from the second drive station. The drive station at the second drive station is quickly accelerated to a target speed for synchronizing the first drive station with the second drive station. After receiving the train, the second drive station then transmits a stop command to the first drive station for fast decelerating the drive station to a stop.

  • Patent number: 7386391
    Abstract: A method generates optimized traffic movement plans. A plan monitor determines a first planning boundary for traffic based upon traffic conditions of a region. A plan generator employs the first planning boundary and repetitively generates first traffic movement plans for the traffic. The plan generator selects one of the first traffic movement plans as a first optimized traffic movement plan, and outputs the same for controlling traffic movement. The plan monitor determines current traffic conditions of the region for a planning window, and updates the first planning boundary to provide a second planning boundary for the traffic based upon the current traffic conditions. The plan generator employs the second planning boundary and repetitively generates second traffic movement plans for the traffic, selects one of the first and second traffic movement plans as a second optimized traffic movement plan, and outputs the same for controlling traffic movement.

  • Patent number: 7356474
    Abstract: A system and method for remotely enforcing operational protocols is provided. In a remote environment, such as that found with a police environment, voice recognition technology is used to determine the situation and invoke actions according to an appropriate protocol. Actions may be set to be mandatory or discretionary. A secure log is maintained of the actions undertaken. Actions include automatically retrieving data from a remote database, automatically communicating with another unit or headquarters, and automating devices used in the remote environment. Voice recognition technology also extracts data from the user's speech and builds variables used as parameters in performing the actions. Data is returned to the user in either audible or textual form and either played to the user on a speaker or displayed on a display device.

  • Patent number: 7328090
    Abstract: The invention relates to a method for controlling the sequence of trains during traffic control, whereby a telephone communication between a traffic controller in a traffic control centre and a driver is carried out. In order to increase security during telephone communication, the traffic controller transmits a driving permit to the driver, in addition to a test code which is specific to the driving permit and determined by a traffic control computer, and the driver inputs the driving permit and the test code into a vehicle appliance which calculates the test code according to the same algorithm as the traffic control computer, and compares the calculated test code with the inputted test code. The driving permit is authenticated only if the two codes correspond.
