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.

A system and method for guidance control on a wheeled bogie is disclosed herein. An electromagnetic engine may be coupled to the wheeled bogie such that the electromagnetic engine may generate magnetically attractive forces between the electromagnetic engine and the rail. The generated force may be used to increase traction for braking and climbing operations. Further, the generated force may be used to counteract hunting oscillation. Still further, the generated force may be used to counteract lift generated by the wheeled bogie operating in a turn with cant.

A process for detecting a derailment of a rail vehicle having two or more rail vehicle parts and one or more articulations through which adjacent rail vehicle parts are rotatably connected with one another includes determining an angle of rotation between adjacent rail vehicle parts, and/or a quantity derived from the angle of rotation. The process further includes comparing the angle of rotation or the derived quantity with at least one reference value or threshold, or with at least one reference value range or threshold range. A test criterion indicating whether or not there is a derailment is defined based on the at least one reference value or threshold, and/or an expected relationship of multiple angles of rotation, and/or an expected relationship of the multiple quantities derived from the angles of rotation, relative to one another. The method further includes determining whether or not the test criterion is met.
