These methods and systems detect an incoming train entering a geographic area defined by a railyard, store an entry time indicative of a time at which the incoming train entering the railyard was detected, detect the incoming train coming to a stop in a subyard of the railyard, store a stop time indicative of a time at which the incoming train came to a stop in the receiving subyard, calculate an incoming train latency time by subtracting the entry time from the stop time, and store the incoming train latency time as an incoming train latency time record.
This invention is a railroad wayside signal system positioned adjacent to a railroad track that comprises a mast that is attached to a support structure in an upright position. A signal head having one or more signal lights is mounted to the mast such that a locomotive operator in an approaching locomotive can see the signal lights. The mast pivots with respect to the support structure between the upright position and a substantially horizontal position for maintaining and/or aligning the signal head and signal lights. The signal system may also be equipped with one or more actuators operatively connected to the signal head. A remote control unit is placed in communication with the actuators, and the remote control has an input mechanism for inputting a command representative of a direction of rotation of the signal head. The remote control also generates a signal in response to the input command that is representative of one or more directions of rotation.
A method and computer program product are provided for monitoring integrity of a railroad train and determining passage of the train relative to a plurality of virtual blocks defined by wireless transmissions along a section of track over which the train travels. The virtual blocks provide safeguards for the travel of the train relative to other trains on the section of the track when there is a shared use of the section of track. In aspects thereof, the method allows collecting data useful for evaluating conditions that may affect train integrity from at least one sensing device at a end of train location. The method further allows collecting data at a head-of-train location, with the data collected at the head-of-train corresponding to the type of data collected at the end-of-train location. The data collected at the end-of-train and at the head-of train location is processed to determine whether the entire train has cleared a respective one of the virtual blocks. In the event this determination is unable to reach a clearance for the respective block, a cautionary status is associated with the virtual block. The cautionary status for the virtual block is automatically communicated to an offboard system, which is responsible for managing shared use of the track by other trains.
A railway power supply system and method for electrically powering an electrical device are provided. The electrical device is situated along a railway and is powered through an electrically conductive line generally used for carrying an electrical signal to a railway signaling device. The power supply system includes a power injector coupled to the line. The line is used for carrying a signal to the signaling device at a first frequency value for performing a signaling operation. The power injector is configured to introduce at the line a power signal for powering the electrical device. The injected power is at a second frequency value that is sufficiently spread apart from the first frequency value to avoid interference with the signaling operation of the railway signaling device. The power supply system further includes a power collector coupled to the line and to the electrical device for passing the signal for powering the electrical device.
A scheduling system and method for moving plural objects through a system described as a freight railway scheduling system. The scheduling system utilizes a cost reactive resource scheduler to minimize resource exception while at the same time minimizing the global costs associated with the solution. The achievable movement plan can be used to assist in the control of, or to automatically control, the movement of trains through the system. Train location reports used in the automatic updating of the movement plans are selectively disabled for individual trains as a function of the activity scheduled for that train.
A data gathering apparatus comprises a power generation device configured to generate power via movement of the rail. The data gathering apparatus further comprises a sensing device configured to receive power from the power generation device and to sense at least one property of the rail, wherein the property of the rail is at least partially defined by a vehicle traveling on the rail.
A lost motion apparatus for adapting a typical in-tie switch machine, designed for use with interconnected switch points, to be used as an in-tie machine for moving the movable V-point of a movable point frog assembly.
System and method for monitoring status of a visual signal lamp. The system includes at least one optical fiber comprising a first end and a second end. The first end is positioned proximate to the signal lamp and is oriented to capture a portion of light signal emitted by the signal lamp when the signal lamp is illuminated. The system also includes a photodetector positioned proximate to the second end of the optical fiber and configured to receive the portion of light signal. The system further includes a threshold detection circuitry connected to the photodetector and configured to detect a lighting parameter in relation to the signal lamp according to a predetermined criterion.
An operational status detection system for a railroad warning device having a warning light, comprising: a photodiode configured to generate a signal corresponding to a light output of the warning light of the railroad warning device; an amplifier for increasing a signal strength of the signal and providing an output corresponding to the signal; a filter for receiving the output, the filter being configured to only allow portions of the output corresponding to the light output of the warning light to be presented as an output signal of the warning light; and a microcontroller receptive to the output signal and for comparing the output signal to a threshold value, the threshold value corresponding to an acceptable light output of the warning light.
