For automatic regulation of train traffic and greater safety of railway transport, in recent years in Europe and in Bulgarian railways the system ETCS (European Train Control System) level 1 with the so-called infill balises is used. The distance from the infill balise to the respective main signal is disputable and depends on a number of parametres, as it differs among the various railway administrations. In order to determine the most appropriate place of locating the infill balise in the conditions of BDZ, a software product is developed for automatic calculation of the infill balise location based on various input data. Multiple ancillary data are also calculated, as they are helpful for designing the section in which the infill balise will be located. The product is equipped with a graphical user interface, facilitating the work with it and the data visualization. Subject of this article is a description of the aforementioned graphical user interface and the results from the work with it.
