An intermodal interaction of a railway station with a marine port is described as a queuing system. The main subsystems "carriage-port" and "vessel-port" are described in details, a characteristic of the respective claims and service devices is given. A detailed substantiation of the selected classes of queuing models is presented. The paper contains a description of the problem domain, a conceptual model and its mathematical formalization and identification. A discrete-event mechanism forms the modeling base.
