For the design, construction and monitoring of railway infrastructure facilities, as well as for the maintenance of track facilities, it is necessary to have a spatial database relevant at the time of their production, which should be provided with a continuous survey of infrastructure facilities located in the right-of-way. The article considers the possibilities of introducing geoinformation technologies, including high-precision methods of coordinate-time support, mobile laser scanning, into the production processes of design, construction, operation, repair and diagnostics of railway infrastructure. The existing problems of the widespread introduction of mobile laser scanning technology in relation to the shooting of railway objects are shown.
