Introduction Railway traffic has an increasing role in the transport of large volumes of passengers and goods from one place to another due to the specific needs of users. In order to better meet the customer's needs, it is necessary to provide the best possible quality service. This requires railway lines of adequate characteristics. Line R106 is a regional line in Krapina - Zagorje County which connects the whole county. However, this line is at the end of its exploitation cycle due to long time non-maintenance. In order to maintain their function and to be able to provide quality transportation services in the area through which it passes, it is necessary to modernize and adapt it to modern demands and needs of railway transport users. One of these requirements is certainly a shorter and faster journey, as a large number of passengers use rail transport to their final destination in Zagreb. In this paper a brief review of previous research and methodology is given together with the description of the region and railway line which it passes and the problems which were detected on this line. After analysing the problem, an overview of several realistically possible variants of the proposed solutions to the detected problems will give, as well as their simulations on a pre-made model of the railway line, which was verified and corresponds to the real state. After testing all variants, the one that gives optimal results is selected and upgraded and proposed for implementation. Finally, a proposal is made for a new timetable organization based on the best use of the Diesel Motor Unit (DMU) and the shortest travel time and final conclusion is given. 2. Literature review and methodology Many authors conducted different research of regional public passenger transport in Croatia. Some of them gave different proposals and solutions. The author (Mikulčić et al. 2017) analysed the work on the regional R201 and R106 and local L202 lines and gave suggestions for new variants of the traffic organization on the R201 line. The impact of the repaired and modernized line on the other connected lines it is was also analysed. Author (Goluban 2019) in his work observed a new organization of public passenger transport after the modernization of the railway and gave suggestions of different variants of the traffic organization. Other authors (Abramović and Šipuš 2020); (Gasparik et al. 2015) also investigate the quality of regional public passenger transport and by survey question passenger's opinions about their satisfaction with transport services. In paper (Ljubaj et al. 2018), it was mentioned and proved that after the modernization, the capacity increase of the R201 line is 40%. Such
