  • 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.

    Abstract: A computerized system and method of managing subway trains along a two-track subway line to allow express travel in combination with local service. Express trains catch up to local trains at express stations along the line, and provision is made to allow the express trains to physically or “virtually” pass the local train at those stations. Embodiments in which the express trains physically pass the local train include direct train-to-train transfer facilitated by side-by-side tracks at the express station occupying reduced foot-print. In other embodiments, virtual passing is accomplished by changing the type of service provided by trains at express intervals: a local train “transforms” into an express train and vice versa. Embodiments enable passengers to transfer between trains at express stations so that these “relay” passengers can travel faster than any specific train.

  • Patent number: 8234023
    Abstract: A system for regulating the speed, position and/or power of a powered vehicle, which is traveling on a track system according to a planned trip. The system comprises a database having data relative to the planned trip including a plurality of elapsed travel times associated with a planned speed, position and power. One or more controllers provide data including data relative to an operating speed, position and power of the vehicle during the trip and an operating time at which the vehicle is traveling at the operating speed, power or position. A regulator may adjust the operating parameter of the vehicle if the difference between the vehicle operating data and planned trip data exceeds a predetermined threshold speed.

  • Patent number: 8224509
    Abstract: A system for controlling movements of a vehicle along a guideway includes an array of targets that are mounted on the vehicle, and a series of wayside sensors that are mounted on the guideway. A signal processor monitors the passage of targets past appropriate sensors and uses resultant signals to derive parametric values that are characteristic of the vehicle's movements. The parametric values are then coordinated with a controller for the operation of a linear synchronous motor that propels the vehicle.

  • Publication number: 20120179310
    Abstract: A method for operating a train includes: (a) using a processor carried by the train, creating a trip profile which is computed at so as to substantially optimize an operating parameter of the train which depends on multiple operating variables; (b) operating the train along a route at speeds determined by the trip profile; (c) identifying a target location ahead of the train which cannot be cleared in a desired time if the train operates in accordance with the trip profile; and (d) operating the train at a clearing speed substantially faster than determined by the trip profile until the target location is cleared. A computer program product is provided for carrying out the method.

  • Patent number: 8190313
    Abstract: A system is provided for reducing a penalty period for a distributed power train. The distributed power train includes a braking system that switches into an application state upon commencement of the penalty period. The braking system includes a fluid carrying brake pipe which connects a first locomotive and a remote locomotive. The system includes a sensor positioned within the distributed power train, which measures a parameter related to the operation of the braking system. A control processor is positioned within the first locomotive, and is coupled to the sensor. Subsequent to the commencement of the penalty period, the control processor monitors the measured parameter and switches the braking system from the application state into a release state to reduce the penalty period, based on the measured parameter falling within a predetermined safety range. Additionally, a method is provided for reducing a penalty period for a distributed power train.
