摘要： A method includes obtaining creep measurements and tractive/braking measurements from at least one vehicle system at different locations along a route segment while the at least one vehicle system moves through the route segment. The method also includes calculating tribology characteristics of the route segment at the different locations. The tribology characteristics are based on the creep measurements and the tractive/braking measurements from the at least one vehicle system. The tribology characteristics are indicative of a friction coefficient of the route segment at the different locations. The method also includes determining an effectiveness of a friction modifier applied to the route segment based on the tribology characteristics.

摘要： A method for forming 3D image data representative of the subsurface of infrastructure located in the vicinity of a moving vehicle. The method includes: rotating a directional antenna, mounted to the moving vehicle, about an antenna rotation axis; performing, using the directional antenna whilst it is rotated about the antenna rotation axis, a plurality of collection cycles in which the directional antenna emits RF energy and receives reflected RF energy; collecting, during each of the plurality of collection cycles performed by the directional antenna.

摘要： A control method operates a rail vehicle. The method is carried out in a computer-assisted manner on the basis of a vehicle control program. Accordingly, it is provided that the vehicle control program operates with the use of detected driving and/or surroundings data being detected by on-board or train-board sensors.

摘要： A method of determining the actual position of a track relative to a fixed point located in a lateral vicinity of the track by using a registering device being mobile on the track includes surveying the position of the fixed point relative to the track. The registering device is moved along the track, image pairs of the lateral vicinity of the track are continuously recorded by a stereo camera system on the registering device and the fixed point is searched for in the image pairs by pattern recognition carried out in an evaluation device. Upon recognition of the fixed point, the position of the fixed point relative to the track is determined by evaluating at least one image pair. This creates the possibility of surveying fixed points in passing with the configuration of the fixed point not being bound to any special form. A measuring system is also provided.

摘要： A monitor vehicle for a rail system includes a wheeled trolley, an overhead vehicle, a supporting structure, and a first sensor. The wheeled trolley is above a rail of the rail system, is operable to move over the rail, and has a bottom surface. The overhead vehicle body is suspended by the wheeled trolley and below the rail. The supporting structure connects the wheeled trolley and the overhead vehicle body. The first sensor is on the bottom surface of the wheeled trolley and is configured to detect a first parameter of the rail of the rail system.

摘要： A system for real-time asset recognition and location includes an image capture and recognition system having a plurality of image capturing devices for capturing image data of an area surrounding a railroad track and a position determination system for determining a position of assets in the area surrounding the track. A processor analyzes captured image data and recognizes assets and correlates a determined position with each recognized asset. The system recognizes assets and determines positions of assets in real-time as the system is transported along a railroad track by a survey vehicle. The captured and analyzed data is stored to a data storage unit for immediate use in updating a railroad asset data base, subdivision files, or positive train control (PTC) files.

摘要： A method and an apparatus for identifying faults in a computer-aided manner for a technical system including a switch and a switch drive is provided. A fault or a disruption in the switch and/or in the switch drive is detected by capturing a temporal profile of a measurement variable of the switch drive. A simulation model is provided for the technical system and a fault situation is set by means of setting values of the simulation model, wherein the setting values are assigned to the fault situation. The technical system is simulated by means of the simulation model, wherein a simulated temporal profile of the measurement variable is captured. The simulated temporal profile is compared with the temporal profile of the measurement variable of the switch drive, wherein the fault situation is assigned to the detected fault on the basis of the comparison.

摘要： The present invention defines a method of determining a vertical profile signal of a rail surface that includes, obtaining a vertical acceleration signal acc1, by measuring vertical acceleration of a bogie of a rail vehicle that runs on the rail surface; processing the vertical acceleration signal to obtain a vertical velocity signal; determining the vertical profile signal of the rail surface, by using the vertical acceleration signal and the vertical velocity signal as inputs to a simulation model of the bogie, the model having an unsprung mass connected to a sprung mass, the vertical acceleration signal acc1 represents the vertical acceleration of the unsprung mass; and measuring a linear velocity signal of the rail vehicle, the linear velocity signal is used in the step of determining to convert the vertical profile signal from the time domain to the distance domain.
