Japanese-style ATC cab signalling indicator. Automatic train control (ATC) is a general class of train protection systems for railways that involves a speed control mechanism in response to external inputs. For example, a system could effect an emergency brake application if the driver does not react to a signal at danger.
In United States and Canadian aviation, the Aeronautical Information Manual (AIM) [1] (formerly the Airman's Information Manual) is the respective nation's official guide to basic flight information and air traffic control procedures. These manuals contains the fundamentals required in order to fly legally in the country of origin.
In machining, an automatic tool changer (ATC) is used in computerized numerical control (CNC) machine tools to improve the production and tool carrying capacity of the machine. ATCs change tools rapidly, reducing non-productive time. They are generally used to improve the capacity of the machines to work with a number of tools.
The first full-scale implementation of TASC was on the Tokyo Metro Ginza Line, the oldest subway line in Japan, where it, along with a new CS-ATC cab signalling system, replaced the line's previous mechanically-operated automatic train stop (ATS) system in 1993, [1] enabling a massive upgrade of the line's route capacity and frequency between ...
Automatic Train Control, or ATC, adds in-cab enforcement to these and will apply the brakes if a dangerous situation arises, such as when the next signal is displaying a stop indication but the engineer has not begun slowing the train. Some form of ATS or ATC is required on all U.S. rail lines that operate at 80 mph or more.
An Advanced Train Control System (ATCS) is a North American system of railroad equipment designed to ensure safety by monitoring locomotive and train locations, providing analysis and reporting, automating track warrants, detecting blind spot and similar orders.
Advanced Civil Speed Enforcement System (ACSES) is a positive train control cab signaling system developed by Alstom. [1] The system is designed to prevent train -to-train collisions , protect against overspeed, and protect work crews with temporary speed restrictions.
At no point can the ATC system override the maximum speed limit enforced by the cab signal system. Automatic Train Operation controls trains so that, between stations, they will move at the speed specified by the automatic train protection and automatic train supervision sub-systems.
