  • Patent number: 10829136
    Abstract: A protection method for a railway network which is divided into track sections by track elements, and which can be traveled on by vehicles. The vehicles request steps for assignment from selected track elements to form travel path elements. In order to optimize the train service, each of the selected track elements provides at least one signal for each vehicle that requests at least one of the steps for assignment as a travel path element from same. A protection system for a railway network is configured to carry out the protection method.

  • Patent number: 8924048
    Abstract: A method for automatically controlling braking of a powered system or consist includes automatically applying a first degree of braking to a consist during a first time period when a powered unit of the consist is being locally or remotely controlled via an onboard control system in an absence of control inputs from an onboard operator. The first degree of braking is based on a first deceleration force selected so that the consist is slowed in a manner effective to limit a peak deceleration rate experienced by the consist sufficient for reducing unintended movement of at least one of one or more riders or cargo onboard the consist. The method also includes automatically applying a second degree of braking to the consist during a second time period following the first time period.

  • Patent number: 8903574
    Abstract: In a system and method for communicating data in a locomotive consist or other vehicle consist (comprising at least first and second linked vehicles), a first electronic component in the first vehicle of the vehicle consist is monitored to determine if the component is in (or enters) a failure state. In the failure state, the first electronic component is unable to perform a designated function. Upon determining the failure state, data is transmitted from the first vehicle to a second electronic component on the second vehicle, over a communication channel linking the first vehicle and the second vehicle. The second electronic component is operated based on the transmitted data, with the second electronic component performing the designated function that the first electronic component is unable to perform.

  • Patent number: 8820685
    Abstract: A method is provided. The method includes, the railway network being subdivided into resources, the state being driven by a ground controller, and each vehicle including an onboard controller being capable of communicating with the ground controller. The method includes planning, by a regulating unit, of a vehicle's mission, transmitting said mission to the vehicle. The onboard controller of identifying a group of resources permitting the vehicle to continue its mission, reserving the identified resources with the ground controllers, once all of the resources are allocated, interlocking each resource in a required state, verifying that each resource is reserved and is in the required state and, when this verification is positive, extending permission for the vehicle to move on the path corresponding to said group of resources.

  • Publication number: 20140209752
    Abstract: A train control system includes an on-board device 3 mounted on a train 2; a vehicle radio set 4; wayside radio sets 5 that are disposed on a ground; and ground devices 6 disposed in every control sections defined on the track. In each control section, the ground device 6 is connected to the wayside radio sets 5 in the control section. When one ground device 6 fails to transmit information to and receive information from another ground device 6, the one ground device 6 determines that said another ground device 6 has been failed, and then, the one ground device 6 calculates a possible travel distance to a control section of the failed ground device 6 to prevent the train 2 from entering the control section of the failed ground device 6, and then, the one ground device 6 transmits the possible travel distance to the on-board device 3.

  • Patent number: 8380361
    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: 20120217350
    Abstract: A distributed interlocking device, architecture and process are disclosed, and are based on segregating the vital logic for a signal installation by type of signal equipment. A plurality of intelligent signal devices is disclosed, wherein each intelligent signal device is used to control a basic signal unit. In turn, a signal unit includes a set of signal apparatuses that are geographically and logically interrelated. An intelligent signal device receives data related to the states of other signal devices, determines and controls its own operational states, and communicates its own operational states to other devices. A generic intelligent signal device is also disclosed, and is based on a parameterization approach. The device is then customized to a site specific location by activating the appropriate parameters for that location. Further, a new vital change management process, and a new failure recovery scheme are disclosed.

  • Patent number: 7822491
    Abstract: A method and system for the operation of trains on a rail network, and particularly in the context of long-haul rail networks. The invention provides a method and system which monitors the progress of a train on a long-haul network, calculates efficient control profiles for the train, and displays driving advice to the train crew. The system calculates and provides driving advice that assists to keep the train on time and reduce the energy used by the train by: (i) monitoring the progress of a journey to determine the current location and speed of the train; (ii) estimating some parameters of a train performance model; (iii) calculating or selecting an energy-efficient driving strategy that will get the train to the next key location as close as possible to the desired time; and (iv) generating and providing driving advice for the driver.

  • Publication number: 20100191395
    Abstract: A method and a configuration for the operation of a railroad line include at least one signal box for providing line-block-section-specific light signal data and a line side system for an intermittent automatic or inductive train control system at line block section ends. In order to dispense with line side light signals and still be able to continue to use a signal box logic concept for light signals, the signal box transfers the line-block-section-specific light signal data over a radio system to a rail vehicle and the intermittent automatic or inductive train control system transfers line-block-section-specific data to the rail vehicle during passage by the rail vehicle. The rail vehicle determines the light signal data assigned to the line block section by comparison of line block section specifics.

  • Patent number: 7756613
    Abstract: Trains and points are patrolled by a telegram containing the block occupancy information as a section that only one train is permitted to occupy, the information for giving lock position instructions to a point, and the point position information. This telegram is updated in order to get the right of block occupancy that is not held by other trains, and to give lock position instruction to the point. The train checks the block which this train is allowed to occupy, confirms that the point in this block has been set to the lock position specified by this train. Reading the aforementioned telegram, the point checks the lock position instruction given to itself and controls its lock position. A signaling system characterized by reduced designing and manufacturing costs is provided.
