Computer application for railway track realignment

The topic of this article is the issue of railway track realignment. For this purpose, a computer software application was created that supports computations and generates a report needed for regulation of the trajectory of the railway. This program gives the ability to import data from measurement of the railway trajectory and then perform the calculation of the mathematical realignment. The result of this calculation is the basis for creating a project of the railway track regulation. This program was created in collaborative research project on modernization of railway lines in Poland at the request of one of the railway companies.
