With regard to system structure, conventional systems have a vertical independent structure because individual pieces of equipment such as automatic train control (ATC) equipment, electronic interlocking equipment and facility monitoring equipment have been separately developed and introduced into the systems. By contrast, our unified train control system's concept is a horizontal and hierarchical structure consisting of a "function layer", a "network layer" and a "terminal layer". This horizontal hierarchical structure is intended to make the systems lean and simple by bringing corresponding segments of those pieces of equipment together into each layer and to allow evolution of the systems by accommodating flexibly the train operators' needs. The function layer consolidates functions of individual pieces of the conventional equipment and manages the whole system centrally. The network layer provides standard network interfaces by means of IP networking without making users conscious of the existence of a network. The terminal layer facilitates reducing, adding and removing local facilities in an effort of downsizing.
