To control the expanded and more diversified train services associated with extension of the Shin Kansen network, Japanese National Railways has introduced a more sophisticated control system, COMTRAC, by which the dispatcher can accurately and effectively regulate train traffic by fully utilizing computers. COMTRAC will be successively expanded through four stages. COMTRAC will control scheduling and route control, then will incorporate traffic adjustment functions and finally will involve transmission of instructions, delay information and automatic information to passenger stations. Two kinds of computers are used separately for the traffic controls system and the route control system.
