The Communication Based Train Control (CBTC) system reports the real-time train location from an onboard system to a wayside systems and transmits the movement authority through radio communication from the wayside system to the onboard system, and it shall increase railway capacity by allowing the highdensity train control through high information transmission amount between the wayside ATP/AT...

The Communication Based Train Control (CBTC) performs real-time train position report and movement authority transmission through wireless communications between a wayside control center and a vehicle on-board computer. And it has increasing effects of railway capacity by allowing the high-density train control through a high information transmission amount between the on-board and the wayside....

The Automatic Train Operation of a metro line is not so difficult to implement: almost no junction or crossing between lines, rolling stock homogeneity, double track operation, relatively low speed, very simple station track layout, mostly rubber-mounted, and specific site continuously fenced with no level crossing. Tunnels and platform screen doors complete the picture to prevent almost totall...

Since 1981, the Automatic Train Control (ATC) devices have been used to maintain a safe distance between trains on the Yamanote and Keihin-Tohoku lines in Tokyo. Although shorter train headways have been desired for years to increase the line capacities, this has been impossible with the conventional ATC. The authors have developed a new ATC system, the Digital ATC system, to replace the conven...

A trackside computer tracks all trains in the assigned section of line and calculates an appropriate movement authority for each train. As a result, trains are routed continuously and can run at shorter headways than when driven manually on sight. In fully automated mode, metro trains are driven by the Automatic Train Control (ATC) in combination with control and protection of the line by inter...
