Focus: List of train control systems in various countries

Introduction: 7.23 EMU rear-end event affects everyone's heart, and the train control system has become the focus of attention. Since the beginning of the train operation, with the continuous improvement of the operating speed, the train control systems in various countries have also been developed and improved. Today, we have a look at the train control systems of countries in Europe, America and Japan.

The speed increase of trains is an important goal for the development of railway technology, and the safety valve that is continuously realized by this goal is the train operation control system (referred to as the "train control system"). The function of the train control system is to prevent the train from exceeding the allowable speed specified by the line, and to manage the blocked area between tracks to prevent trains from running rear-end accidents. Since the beginning of the train operation, with the continuous improvement of the operating speed, the train control systems in various countries have also been developed and improved.

â–  Japan Train Control System ATC

The operation control of the brake system of the Shinkansen in Japan is divided into three parts: the first is the automatic train control system ATC; the second is the control handle braking, the train departure, acceleration, time adjustment and station parking and from 30km/h to All operations in the parking place are achieved by the driver through the handle; the third is the operation of emergency braking. When an accident occurs, the driver operates the emergency brake switch UBS to achieve emergency braking.

â–  European train control system ETCS

The European Train Control System (ETCS) is a unified train operation control system established to ensure the interoperability of high-speed trains within the European railway network. ETCS is a point-type train control system based on European transponder (plus local European loop) and on-board equipment, and can adapt to a maximum operating speed of 200-250km/h. The Central Dispatch Center determines the order of the train access and the train operation. The onboard equipment automatically controls the operation of the train based on the distance to the preceding train, speed requirements, and the like.

â–  American Railway Train Control System ATCS

The American Railway Train Control System (ATCS) consists of five major functional modules: dispatching command center/central control system; locomotive on-board equipment to realize train control and positioning; wireless data communication system; two-way information transmission between train and ground control center ( Voice and digital communications); ground equipment, including train positioning transponders, wireless relay base stations, antennas, etc.; line maintenance of mobile terminals. ATCS is a closed-loop decentralized control system that uses computers, wireless and digital communication technologies. It helps train drivers to optimize driving by rationally arranging trains to go over and meet. Dispatch and command centers timely notify trains or line data, and on-board computers monitor operations and equipment at any time. Status, timely measures to eliminate hidden dangers and increase safety; provide effective operation plans and operation adjustment plans, introduce mobile obstruction, and increase the capacity of existing lines.
