A system for supervising and controlling the movement of a railway vehicle is provided, wherein a plurality of wayside controller units are each distributed to a plurality of wayside controller locations by a multi-access carrier, such as a fiber LAN or IEEE 802.3 Ethernet, for instance, such that supervisory and control operations may be communicated between each of the wayside controller units with a multi-access protocol on the multi-access carrier. The present invention replaces the use of a serial-link protocol for point-to-point communication with a multi-access protocol on a multi-access carrier. In a preferred embodiment, a computer-based control system may be connected through the multi-access carrier, so that communication is achieved solely with multi-access protocols. Related art Centralized traffic control (CTC) functions may be eliminated from a global services (GS) block of the central office (CO) and implemented as Distributed Traffic Control functions that are distributed to the wayside controller units. |
