Abstract: A portable, single-fixation, magnetic derailment mitigation device may be fixed on a rail track for measuring the deflection of the rail track. The magnetically fixing device is used for measuring vertical track deflection (sleeper voids), horizontal track deflection, ambient and rail temperature, rail angle, vibration, displacement, and location. The derailment mitigation device sends digital notifications and/or alarms during the live train and/or freight operations to help prevent derailments, rail buckles, breaks, and pull apart. The measured data and/or all events obtained from the derailment mitigation device is stored in the data storage such as cloud storage and viewed from any smart devices.

Abstract: A method is provided for determining anomalies associated with a railcar wheel of a railcar wheelset, or a railcar bogie assembly that the railcar wheelset is part of, or a track, during motion of the railcar wheelset on a track. A wheel-mounted sensor ring is removably attached to a hub portion of a railcar wheel of a railcar wheelset. The sensor ring includes one or more sensors, such as inertial measurement units (IMU's), mounted thereto to measure parameters that are used for determining the anomalies during motion of the railcar wheel on the track. The railcar wheelset is moved on the track. The measured parameters are collected from the one or more sensors. The measured parameters are used for determining the anomalies during motion of the railcar wheel on the track.

Abstract: A metro rail corrugation measurement method based the Seq2Seq model and vibration and noise data fusion comprises the following steps: Constructing a time series data set corresponding to floor longitudinal acceleration and train speed based on historical data of metro trains; Constructing the metro train mileage matching prediction model based on the Seq2Seq model, training the metro train mileage matching prediction model by time series data sets, and inputting the inside floor longitudinal acceleration of the metro train to be detected into the trained metro train mileage matching prediction model to obtain the running speed of the metro train to be detected. According to the vibration and noise data of the metro train to be detected, the vibration and noise composite index of the rail corrugation is calculated to determine the wavelength and amplitude information corresponding to the rail corrugation.

Abstract: A system and method for automating railroad maintenance for a tie gang using electronic tie marking (ETM) configured to optimize railroad asset maintenance. The system enables the automating of an adaptive maintenance process for the asset that is being maintainanced. The system can identify a railroad asset scheduled for maintenance using various forms of inspection including real-time kinematic (RTK)-corrected GPS data, radar signal processing data, and real-time imaging. The system also provides for the acquisition and upload of asset pictures for verification and analysis of a railroad asset. The system can identify a next location to perform maintenance and can calculate an optimum path based on sensor input incorporating machine-specific and environmental characteristics. The system further can provide a customizable user interface to identify, track, and process information related to maintenance of the railroad asset.

Abstract: A deployable measurement system for analyzing a rail of a railroad track includes a housing, a reflecting assembly coupled to the housing, a movement assembly coupled to the housing, and an optical measurement system disposed within the housing. Both the housing and the reflecting assembly are moveable between a stored position and a deployed position. The movement assembly includes a deployment assembly that moves the reflecting assembly from the stored position to the deployed position, and a retraction assembly that moves the reflecting assembly from the deployed position to the stored position. The optical measurement system emits and receives light. The reflecting assembly reflects the emitted light toward the rail. The reflecting assembly reflects light reflected off of the rail toward the optical measurement system. The light received by the optical measurement system is used to measure parameters related to the rail.
