“…Such a solution is currently implemented in Poland with respect to relays used in railway traffic control devices. A possible way of selecting risk assessment criteria and developing a risk model for supporting such decisions was the subject of our further research with the participation of experts (Smoczyński 2018;Smoczyński et al 2019). We have also taken up the subject of Maintenance Board indicating new safety measures (Gill, Smoczyński 2018).…”

The railway network in Poland with over 19000 km is one of the biggest in the European Union (EU). At the same time safety indicators collected by the European Union Agency for Railways (ERA) show that it is one of the least safe in Europe. Consequently, all the actions taken in safety management of Polish Railways are particularly important for the society. In 2015, there was a change in the main infrastructure manager’s rulebook on track maintenance. A new process rule was introduced to replace a large set of long-established action rules. However, supervision reports of the Polish National Safety Authority indicate that the new rule is not used properly. Therefore, the current process of taking maintenance decisions on Polish Railways was described and a novel concept of maintenance layers and Maintenance Board meetings was proposed. The change would allow to choose the order of maintenance activities in a more objective way than it is done nowadays, without the necessity to make any major investments.

“…The documents of the European Railway Agency or the Polish Office of Rail Transport present mainly the statistical data [2,3,12]. Another important direction of studies in the last years is the modeling of safety systems at railway crossings in terms of risk management and risk model development [1,8,9,19,20].…”

In this work, safety analysis at the railway level crossings is presented using advanced mathematical modelling. Resistivity of track subgrade panels is taken into account. The analysis does not refer to the assessment of the current regulations. Specific cases of generalized dynamic system are considered by introducing operations S=∆, S=P defined in space C(N) of real sequences. In this model, generalized discrete exponential and trigonometric functions that reflect the oscillatory nature of the analysed quantities are used. The advantage of the analyzes is the avoidance of numerical errors. We show also the importance of the resistivity of track subgrade panels in safety at the level crossings. The safety at the level crossings can be increased through providing track subgrade panels with appropriate resistivity to minimize negative effect of stray currents. The results may be used to evaluate selected safety indicators as well as to predict safety levels and to determine the ways of improving safety.
