Station, Block, Or Train-order Signals Patents (Class 246/14)
  • Patent number: 10766511
    Abstract: A railroad switch indicator, that operates independently of the mechanism for operating the switch, for signaling the position of the switchpoints via a flexible mechanical cable connected to a railroad switch amplifier mechanism. The railroad switch amplifier mechanism has linkage members attached to a crossbar connecting inner stockrails and to a pivoted lever arm, the output arm of which is attached to the mechanical cable. The flexible mechanical cable allows the railroad switch indicator to be positioned remotely from the switchpoints and switch amplifier mechanism in a highly visible and easily serviced location.

  • Patent number: 9879384
    Abstract: A travelling vehicle system includes an intermediate track; first tracks; second tracks; a first switching track which connects the intermediate track and one of the first tracks to an other one track; and a second switching track which connects the intermediate track and one of the second tracks to the other one track. When a travelling vehicle travels on the intermediate track, a travelling vehicle controller determines before the travelling vehicle enters the first switching track that the travelling vehicle can enter both the first and second switching tracks in the case of determining that the first track on which the travelling vehicle is currently travelling is connected to the intermediate track and determining that the intermediate track is connected to the second track selected by the travelling vehicle.

  • 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.

  • 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.

  • Patent number: 7983806
    Abstract: A system for computing car switching solutions in a railway switch yard. The system is computer based and has an input for receiving data conveying information about one or more arrival trains arriving at the switch yard and data conveying information about departure trains to depart the switch yard. A processing entity processes the data and computes car switching solutions for the railcars.

  • 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.

  • Patent number: 7359770
    Abstract: The present invention is directed to a system and method for optimizing the dynamics and energy usage of long vehicles such as freight trains by determining their operating conditions and calculating an optimal sequence of power and braking control actions. The sequence calculated provides for optimal vehicle dynamic behaviour with minimum energy usage in accordance with the train type, track topography and train operation rules and policies. The method and system serves as a management tool for the driver and reference signals for a train cruise control or autopilot system.

  • Patent number: 7200471
    Abstract: A train control system and method for ensuring that a train cannot be moved from a section of track not on a main line to a section of track on the main line until both a movement authority for the section of main line track and a circulation authority for the section of track not on the main line are received.

  • Patent number: 7099754
    Abstract: In order to propose a method of promptly judging movement of a train between block sections with a minimum number of transponders, an on-ground train control part for controlling operation of a train; an on-ground communication means capable of performing communication of information by coming within a specified range; and a sending-and-receiving part capable of sending the information received by the on-ground communication device to the on-ground train control part and receiving the information sent from the on-ground train control part, are provided, thereby, a position of presence of train is grasped by receiving a speed of the train using the on-ground communication means when the on-train communication means attached to the train comes near.

  • Patent number: 7079926
    Abstract: A train control system includes positioning systems at the end of the train and at the front of the train, allowing the conductor or engineer to unambiguously determine that no cars of the train have become detached. The positioning system at the end of the train is also used to verify that the entire train has cleared a block. This information can be relayed to a dispatcher, thereby eliminating the need for trackside sensing equipment. A control unit prevents the train from moving without an authorization that includes the train's current position.

  • Patent number: 6666411
    Abstract: A vehicle control system and method in which a plurality of beacon tags are disposed along a length of a track for a predetermine number of blocks. The beacon tags each provide information pertaining its location. Each vehicle that passes along the track has a tag reader that solicits information from the beacon tags and a transmitter that transmits the solicited information, as well as vehicle identification information for the transmitting vehicle, to a wayside control unit. The wayside control unit receives the transmitted position information and vehicle identification information and in turn transmits a single broadcast of information pertaining to each of the blocks of the predetermined number of blocks. This signal is received by all of the vehicles, which use only the information about immediately approaching blocks.
