Point disposition of the conditional benchmark network and the railway curve elements

Control of geodetic parameters is very important for traffic safety on the railways. Such control must be performed regularly because of the deviation of the track axis due to train traffic. The purpose of the article is the development of a mathematical rationale for the placement of railway benchmarks for the creation of the ‘own’ conditional benchmark network of the railway. These permanent repers are the basic points for both the construction stage and operation stage. The method is described and the curve coordinates from any point of the conditional benchmark network of the railway have been obtained.
