  • Patent number: 7137600
    Abstract: A method for automatic train control in a digitally controlled model railroad system includes detecting a polarity change of a track voltage applied to the track by means of a digitally controlled motor vehicle running on the track. The track voltage being a modulated control voltage which is normally symmetric and asymmetric in galvanically isolated track sections. After each detection of a change of polarity, the voltage level of the control voltage applied to the track is sampled independently for each rail of the track by means of the digitally controlled motor vehicle running on the track. The voltage values sampled for each rail of the track are compared to each other and evaluated with regard to any asymmetry occurring in the amplitude of the track voltage with reference to each rail of the track. Depending on the result of the evaluation, the travel operation of the motor vehicle is influenced that is otherwise controlled by the digital control system.

  • Patent number: 6619593
    Abstract: A two-piece, compact wireless railroad grade crossing motorist warning device comprising: a transmitter that transmits a non-audible analog radar beacon signal to be installed on a train and a receiver to receive the non-audible analog radar beacon to be installed on a motor vehicle. The receiver warns the motor vehicle operator of the train approaching a nearby railroad highway intersection without substantially increasing the ambient noise level in the surrounding community adjacent to the intersection.

  • Patent number: 6088635
    Abstract: A method and monitoring unit for recording the status of a railroad vehicle prior to a potential accident. In a monitoring unit mounted in or on a railroad vehicle, such as a locomotive, a video camera is provided to continuously view a scene that the railroad vehicle approaches. The monitoring unit continuously monitors the status of an emergency brake of the railroad vehicle and the status of a horn of the railroad vehicle. Video signals from the video camera are continuously stored. A control unit in the monitoring unit detects the application of both the emergency brake and blast of the horn within a predetermined time window. Video signals from the video camera are captured for a predetermined period of time after detecting that the application of the emergency brake and horn blast within the predetermined time window.

  • Patent number: 5680120
    Abstract: A transportation safety apparatus and method for the detection of obstacles which lie off the line-of-sight or beyond the field of view of a moving vehicle entails shooting a laser beam through the air from a moving vehicle, capturing the beam and passing it to a fiberoptic relay which transmits a laser pulse to a distant site, and receiving a reflection thereof if the site is clear of obstacles. The pulses are received within about 10-20 microseconds per kilometer of relay length from the time of launching, permitting monitoring of the probe-site in real-time.

  • Patent number: 4094252
    Abstract: A monorail track switch and method is disclosed wherein the track switch senses the approach of a train and automatically aligns itself to accommodate passage of the train. Circuits are provided to selectively deenergize a movable track section when in nonaligned position and to re-energize the track section when properly aligned. Novel structure and method is also provided for lowering the movable track section onto rollers to facilitate movement and thereafter lifting the track section into horizontal alignment with the train path. Electronic lockout circuits prevent a train from overrunning the switch when the switch is in a nonaligned position.
