Assemblies, systems, and methods for inspecting vehicles are disclosed. An assembly can comprise one or more cameras, one or more light sources s, and a housing configured to attach to a railway. The one or more cameras can be configured to capture images in a generally vertical direction and can be located below a top surface of one or more ties of a railway when the inspection assembly is attached to the railway. The housing can comprise a base a base configured to at least partially support the one or more cameras and the one or more light sources and a shroud sloped downwardly in a direction extending away from the one or more cameras.

Systems and methods for gathering data on passing vehicles is disclosed. The system can comprise a support structure spanning across a railroad track; an overhead inspection system comprising one or more cameras for gathering data on the top portion of the passing railcar; a first side inspection system and/or a second side inspection system comprising one or more cameras for capturing images of at least one side of the passing railcar; and/or one or more rail-mounted inspection assemblies comprising one or more cameras for capturing images of the underside of the passing railcar.

Methods and systems for detecting and measuring physical conditions of a railroad track based on image-based distance measurements are provided. In embodiments, at least one object associated with a condition of a railroad track is detected in at least one image. A first point and a second point on the at least one object is detected. A pixel distance between the first point and the second point is measured, and a physical distance-based measurement of the condition of the railroad track is determined, using a conversion model, based on the pixel distance between the first point and the second point. An alert is generated when the physical distance-based measurement of the condition of the railroad track exceeds a predetermined threshold.

A train forewarning braking system is disposed between a train and a track for the train to travel on, is electrically connected to a traffic control center, and has an image monitoring module. The image monitoring module is disposed around the track, is electrically connected to a control system of the train and the traffic control center, and has multiple image capture units and multiple display units. The image capture units are disposed at spaced intervals near the track and are electrically connected to the control system of the train to capture images of the environment around the track. The display units are disposed on the train and the traffic control center, and are electrically connected to the control system to display the images captured by each one of the image capture units.

Method and a device for detecting defects in an elongated structure able to act as an elastic-wave waveguide, the elongated structure being fitted with a plurality of transducers able to acquire measurement signals of characteristic quantities of elastic waves propagating in the elongated structure, each transducer being coupled to an electronic device, the set of electronic devices constituting a network of nodes configured to process measurement signals received from at least one transducer. The method is computer-implemented and comprises steps of: performing a plurality of local defect diagnoses, based on measurement signals received by a plurality of electronic devices, the measurement signals being acquired for multiple elastic wave emission phases; transmitting, to a remote server in accordance with a low-energy-consumption communication protocol, messages containing information relating to each local diagnosis, the messages being formatted in accordance with the low-energy-consumption communication protocol; aggregating the information contained in the received messages; and performing a global defect diagnosis for determining the presence or absence of a defect in the elongated structure.

Provided is a rail head abrader including a base, a blade, a vertical measurement section and a horizontal measurement section. The blade is disposed on the base, and an upper portion of the blade is engraved with vertical wear rail type selection lines. The vertical measurement section includes: a vertical scale frame slidably mounted on the blade; a vertical digital display device; and a vertical scale frame cursor. The horizontal measurement section includes: a horizontal scale frame disposed in an upper middle of the vertical scale frame; a horizontal measuring rod provided with a horizontal measuring rod probe and engraved with side wear rail type selection lines; a horizontal digital display device; and a horizontal scale frame cursor engraved with a horizontal scale frame cursor locating line corresponding with the side wear rail type selection lines. The horizontal measuring rod is slidably mounted on the horizontal scale frame.

An impact load detector can include a rigid object affixed to a structure for which an impact is to be evaluated. The detector can include one or more sensors which are configured to acquire impact data corresponding to an effect the impact on the structure has on the rigid object. The detector can include a data processor that processes the impact data to evaluate for a presence of a set of faults.
