Now, in connection with necessity of the accelerated rates of development of high-speed movement, perfection of maintained systems of railway automatics is required. In this connection, there is a problem of acceptance of additional measures in increase of traffic safety of trains of the following in a package with a small interval, especially at refusals of devices of railway automatics and other supernumerary situations. Use of satellite radionavigating systems enables to reduce influence of the human factor in management of a railway traffic and as consequence, to raise safety, to increase speed and to reduce intervals of movement. Application of satellite radionavigating systems, in particular GLONASS for definition of a site of vehicles and definition of their speed is used rather recently, but have already found wide application on a railway transportation. A challenge is maintenance of demanded accuracy of positioning of the railway vehicles, necessary for definition of their site on a number the located ways. Presence of one receiver SRNS on the train any more does not meet modern requirements. The technical decision with accommodation of two navigating successors in a train is offered, and one receiver is in a head of the train, the second is in a tail of a train. All navigating receivers of the trains which are being on Site of a way, are incorporated in a uniform information network. Concentration of the information in a computer in a cabin driver of a train about coordinates of a tail ahead of a going train allows to define its speed and actual distance up to it. Presence of this additional information in comparison from a locomotive signal system available in existing systems, raises comfort and quality of conducting a train driver of a train. On the basis of this information in a head behind of a going train the choice with use of the developed software of a rational mode of movement, in view of requirements of increase of safety and To save up resources is carried out. The offered decision allows to realize a mode of movement of trains with reduced, in comparison with existing, an interval that allows to avoid in some cases modernization of existing devices of interval regulation of movement of trains at introduction on lines of movement of high-speed trains.
