Train control systems ensure the safety of railways. This paper begins with a summary of the typical train control systems in Japan and Europe. Based on this summary, the author then raises the following question regarding current train control systems: What approach should be adopted in order to enhance the functionality, safety, and reliability of train control systems and assist in commercial operations on railways? Next, the author provides a desirable architecture that is likely to assist with the development of new train control systems based on current information and communication technologies. A new unified train control system (UTCS) is proposed that is effective in enhancing the robustness and competitiveness of a train control system. The ultimate architecture of the UTCS will be only composed of essential elements such as point machines and level crossing control devices in the field. Finally, a processing method of the UTCS is discussed.
This paper proposes a new UTCS, in which a train control system is realized in a hierarchical structure of a functional layer, a network layer, and a terminal layer, and discusses its processing method. It has been demonstrated that an existing signal system can be flexibly evolved into an ideal CBTC that does not have a base-point controller. While the CBTC will start, for the time being, with an ATP block system in the form of a minimal system for local railway lines, in order to demonstrate its advantages, I will endeavor to realize this proposal as soon as possible, as it will be effective in enhancing the robustness and competiveness of railway systems. The ATP block system is a good example of realizing the essential control concept.
