The paper describes the features of construction and monitoring in cultural and historical heritage areas using the example of the railway bypass of the Inkerman St. Kliment Monastery. The analysis of the current regulatory documents regulating activities in this area is carried out. The stages of geomonitoring are described. The geodetic component of monitoring is considered, taking into account the requirements established by the current legislation.

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.

The improvement of refrigerator wagons is an essential problem in Russia. Different tasks need to be solved. One of them is the improvement of bogie dynamics properties. The authors have developed mathematical models for simulating the dynamics of the refrigerator railway vehicle. The aim of the paper was to determine the experimental condition for theoretical results verification and obtain new information about the wagon. Accelerometer schemes on the bogies and wagon body were obtained that made possible to measure all bogies movements and investigate the influence of longitudinal dynamics on flexible carbody accelerations.
