The management of the train‘s traffic on railway sections is a complex process providing train movement depending on: the type of the line, the way of ensuring the movement in the interstations, the provision of traffic at stations depending on their centralization, the number of receiving station tracks. type and number of trains of different categories. The railway section can be regarded as a transport system consisting of interconnected technological subsystems – interstations and stations. For the examination of the parameters of the section with regard to technical equipment, the implementation of a train timetable and the occurrence of accidents, it is necessary to simulate the operation of a transport system ”railway section”. It is appropriate to regard of complex transport systems as a network of interconnected and interacting technological subsystems (in this case stations and interstations), when modelling. A imitation model of a railway section consisting of single-channel systems (interstations) and multi-channel mass service systems (stations) has been developed. This model makes it possible to realize the running of trains under different station and train traffic parameters, by using the General Purpose Simulation System (GPSS). The model allows for the examination of the system and its parameters at different technical equipment and train traffic size. The developed model can be applied for each studied section when setting the input parameters.
