In the railway transportation system exist many constraints, which combined with disruptions can have important impact on the system operation. The position of trains in a timetable has effect on the transportation system robust-ness. One of the key issues is the allocation of time reserves due to the real occurrence of undesirable events and their consequences. Correct placing of the reserves, as well as optimization of the timetable will be possible after an assessment process that leads to weak node identification. The main goal of the paper is to elaborate a robustness assessment method which will take into account variability of processes in terms of operational factors. A robust timetable is resistant to strokes from undesirable events. In other words, for a full robust timetable there is lack of disruption propagation. The challenge arises how to quantify the robustness of the railway transportation system. Thus, the paper discusses issues related to robustness in context of time re-serves. Correct dealing with time reserves is a multidimensional issue.
