In the area of the Pragersko railway station, infrastructure is being upgraded and renovated. The network for carrying out geodetic works was established before the start of construction works. During the construction works, by removing the foundations of the columns of the railway line, most of the old geodetic points of the polygon and levelling network were destroyed. As part of the thesis, we will present the establishment of the levelling network of points embedded in the foundations of the columns of the railway line. For the determination of heights for all of the new points we previously analyzed the stability of existing points With adjusting the network to the chosen geodetic datum, we determined the heights and height accuracies of all the new points based on the measured height differences.
