Communications in railway centralized traffic control systems: Communications

Centralized Traffic Control system for railways overlaps hierarchically over interlocking and fixed block installations that allows traffic control between railway stations and represents the management core and organization of railway traffic. This paper shows the necessity of CTC use since this centralized control model decisions and related implementation actions concerning traffic control are carried out by the same entity and setting routes or changing signal aspects are tasks performed by remote control from the respective positions. Network management involves the centralized traffic control for an optimum system with the following functions: Ethernet network design; maintenance and control the local network security; remediation of faulty or failing system equipment; the correct management of the local network (IP, communications equipment, specific applications); maintaining appropriate quality standards in terms of network configurations. Presented simulation achieved in MATLAB can be used as a basis for designing an electronic track circuit for train detection and data transmission.
