The role and place of passenger transport services in the modern structure of rail transportation is considered. The need for approach to rail passenger transport as a logistics system, which is characterized by a set of parameters corresponding to the concept of logistics system in general and taking into account the peculiarities of railway passenger transportation is determined. The features of formation of such a system, taking into account the generally accepted theoretical approach and the specifics of rail transport are also presented. The concept of logistic system for railway vehicles is given; its overall structure is reviewed. The structure of the particular transport is defined by rail freight and in passenger traffic. Is an example of a mathematical model of the logistics system of rail passenger services on the basis of sets of incoming and outgoing parameters is determined. The structure of technologic process for goods and passenger transportation by rail from the perspective of logistics is characterized.
