Geodetic support for construction and operation of high-speed railways requires high-precision geodetic work both at the construction stage and during operation of the structure. Geodetic separation network, being the basis of mainline construction, requires special care and accuracy in measurements for its creation. The analysis of studies carried out in this field shows their insufficiency or incorrectness, and the comparison of current rules and regulations documents shows their contradiction. In the article, based on the results of existing scientific works, on the basis of the allowable standard values of outstanding lateral accelerations, the necessary accuracy of building a marking network for the construction of a railway line with speeds up to 400 km/h is calculated. On the basis of the analysis of existing regulatory documents of various countries engaged in high-speed rail traffic, the correctness of the obtained result has been proved. The imperfection of the Russian normative base in the field of construction of such objects is shown. Based on the findings, practical recommendations are given on methods for constructing a planned network for the construction of a high-speed highway and fixing its points, which can significantly reduce the cost and intensity of work on its creation, as well as directions for further necessary research in the field of geodetic support for the construction of high-speed highways.
