  • Patent number: 9071338
    Abstract: A method for controlling data communication within a locomotive consist is disclosed. The method may include receiving, at a first access point, a first set of data packets that represent a communication sent from a second access point via a first set of wires. The method may also include receiving, at the first access point, a second set of data packets that represent the same communication sent from the second access point via a second set of wires. Further, the method may include processing the first set of data packets and the second set of data packets to create a resultant set of data packets and generating, at the first access point, a communication related to operating the locomotive based on the resultant data packets.

  • Patent number: 9043044
    Abstract: A system for communicating a dataset may include at least a first and a second communication line. The system may also include a first transceiver configured to communicate a first data signal indicative of the dataset over the first communication line and a second transceiver configured to communicate a second data signal indicative of the dataset over the second communication line. The system may also include a processor. The processor may be configured to receive the first data signal and the second data signal and compare the first data signal and the second data signal to determine whether the first data signal or the second data signal comprises a more accurate signal. The processor may also be configured to determine the dataset based upon the more accurate signal.

  • Publication number: 20150142226
    Abstract: An apparatus for controlling speed in railway vehicles is disclosed, the apparatus estimates a future train speed and determines a control input (first speed control) configured to control a train speed based on a TTSLC {Time-To-Speed-Limit Crossing, a time taken by a train from a current time to exceed an ATP (Automatic Train Protection) speed profile, which is an ATP speed limit}, and determines a control input (second speed control) configured to control the train speed based on a difference between the ATP speed profile and an actual train speed, whereby the first speed control or the second speed control is selected in response to the TTSLC and outputted to the train.
