The object of the research, the result of which is the presented work, is a comprehensive system of spatial data of the railway infrastructure, within which a high-precision system of coordinates of the Russian Railways has been created, and methods definition of normal heights in the Baltic Heights System 1977. The strategy and prospects for the development of high-speed transport highways (VSM) have been described. Methods for determining normal heights at research sites are given.
