The planned redesign of station Resnik in the south of Belgrade is a good example of questions popping up for the future track topology. Of course, it strongly depends on the traffic forecast and the planned timetable. The challenge is to find a solution which offers a high utilisation of station tracks but also some reserves for future demand. Thereby, operational conflicts should be minimised by the layout itself. Looking at the costs of such a measure, one half is the investment and the other half is the maintenance during the life cycle. Therefore, too many tracks and switches will require more maintenance than less infrastructure assets. In this paper several solutions will be presented and discussed upon their advantages and disadvantages.
