The objective of the paper is to investigate the applicability of stochastic Petri nets for the safety and performance analysis of the railway operation control system. The paper presents firstly the application for safety analysis where the quantification of the danger state probability was used as a reference value. Secondly the performance analysis was carried out by probability evaluation of an operation hindering state. Using a simulation based analysis method of the tool TimeNET 3.0 deterministic as well as general stochastic events in the model could be considered. The approximations of general stochastic events by exponential stochastic distribution are discussed in the paper
