- W4313161808 abstract "The implementation of the concept of integrated development of the scientific and technical project Digital Railway provides for the development of digital technologies in all areas of activity of JSC Russian Railways, including the track economy. In order to monitor the current state of the tracks, digital models of the tracks are created and maintained at the level of modern requirements, used to collect, store and evaluate spatial data on the current state of the tracks and develop recommendations for the prevention and elimination of identified malfunctions. The most effective and universal means of controlling and straightening the track is the coordinate method based on a system of continuous coordinate-digital description of the track in a single coordinate system. Track measuring wagons widely used in the railway network do not allow obtaining the geometric parameters of the track in a single coordinate system. Because of this, in our country and in foreign countries, various track-measuring systems have been developed and are used, allowing to obtain the CMR in coordinates. Therefore, the purpose of theoretical and experimental research is to identify the accuracy of determining the geometric parameters of the railway track using the Gedo track measuring trolley. The method of determining the track geometry, technical characteristics and distinctive features of the Gedo track measuring trolley are considered. A program of experimental studies is described and comparative accuracy estimates of the railway track geometry determination by the geodetic method, using a Gedo track measuring trolley and a rail gauge template are given. It is shown that in connection with the transition of the railway industry to digital technologies for modeling infrastructure facilities, it is most expedient to use the Gedo track measuring trolley for monitoring the geometry of the railway track, which provide the required accuracy of determining the geometry of the track, productivity and obtaining the necessary information in a single coordinate system." @default.
