Abstract

The current legislative decree on Slovak republic is in the line with the applicable European Union standards and is based on the original legislative decrees supplemented and updated to meet the requirements of the European standards. The main European standard for track geometry is EN 13848. This standard specifies the requirements for aligning track geometry parameters that present the quality of track. Quality can be measured by different measuring devices mounted on tracking vehicles. This norm is applied to all track parameters. Each parameter is defined hand in hand with the requirements for its´ measuring, methodology of processing and interpreting of the results. [1] That are the reasons, why there is not only needed to be focus of measurement technology, but on the processing and alignment as well. It is also necessary to focus to an inertial precision of the system. There are few problems, such as impossibility of having the identical detailed survey points on a rail superstructure.
