Abstract

The study describes geodetic inventory measurement techniques used to study the geometry of a selected section of a railway track. Specialized trolleys equipped with various measurement sensors were used in the field tests. The research was carried out in several hardware configurations using various measurement techniques. Then, designs for adjusting the track centerline were prepared for two parallel tracks. The adjustment results were verified with the track geometry included in the longitudinal track profile. Discrepancies between the existing document and the current track geometry were revealed. A new geometry was proposed to optimize the alignment of adjacent tracks. Conclusions were drawn regarding the selection of the optimal inventory measurement technique.
