A crossing gate mechanism includes an electric motor with one or more sensor(s), a crossing gate arm operated via the electric motor, and a controller configured to control the electric motor to raise or lower the crossing gate arm in response to a gate control signal. The controller is further configured to sense a motion of the crossing gate arm and detect an obstruction that prevents the crossing gate arm to execute the motion. Further, an associated method and non-transitory computer readable medium are described.

A degradation estimation system includes a processing unit simulating an operation mode of equipment on a corresponding railroad section at each set-up timing based on corresponding railroad section timetable information, and processing respective simulation results, and an estimation unit aggregating respective processing results of the processing unit. The processing unit simulates a travel transition of each training existing in the corresponding railroad section timetable information as a dynamic of each train based on corresponding railroad section timetable information and a running curve, simulates a state change of each track circuit based on the simulation result and railroad track information, and simulates an operational change of the equipment on each track circuit. The estimation unit aggregates the simulation result of the processing unit indicating the operational change of the equipment disposed on each track circuit, and estimates the degradation of the equipment from the aggregation result.

A crossing gate mechanism includes a gate mechanism enclosure, electrical components inside the gate mechanism enclosure, and a controller inside the gate mechanism enclosure. The controller is connected to and configured to monitor and/or control the electrical components. The controller includes an operator panel for receiving input from a user. In addition, the controller has a user interface displayed by the operator panel. The controller is operable to present information associated with the electrical components on the user interface.

A crossing gate mechanism includes a gate mechanism enclosure defining an interior space, external wires located substantially outside the gate mechanism enclosure, and a terminal board positioned within the interior space of the gate mechanism enclosure. The external wires are connected to the terminal board. The terminal board is coupled to and swingable relative to the gate mechanism enclosure.

A crossing gate mechanism includes a swingable gate arm, a rotatable gate arm shaft fixed to the gate arm, and an electronic sensor assembly coupled to the gate arm shaft. Rotation of the gate arm shaft corresponds with swinging of the gate arm. The electronic sensor assembly senses an angular position of the gate arm shaft and transmits a position signal corresponding thereto. The electronic sensor assembly includes a driving element that is attached to the gate arm shaft to rotate therewith. the electronic sensor assembly also includes a driven element that is driven by the driving element such that rotation of the gate arm shaft causes the driven element to rotate. The electronic sensor assembly is configured to generate the position signal based on a position of the gate arm shaft.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for monitoring vehicles traversing a dedicated roadway that includes an at-grade crossing. In some implementations, a system includes a central server, a gate system, and sensors. The gate system provides access to an at-grade crossing for vehicles. The sensors are positioned in a fixed location relative to a roadway, the roadway including the at-grade crossing. Each sensor can detect vehicles on the roadway. For each vehicle, each sensor can generate sensor data and observational data from the generated sensor data. Each sensor can determine a likelihood that the detected vehicle will approach the at-grade crossing by comparing the likelihood to a threshold. In response, each sensor can transmit data to the gate system that causes the gate system to allow the autonomous vehicle access to the at-grade crossing prior to the autonomous vehicle reaching the gate system.
