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.
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.
Metro was designed to use an Automatic Train Control (ATC) system, which comprises three sub-systems. Automatic Train Protection (ATP) protects trains by separating them so as to avoid collision. Automatic Train Supervision (ATS) routes trains and assists in maintaining adherence to schedule. [ 1 ]
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 Toronto subway uses a variety of signalling systems on its lines, consisting of a combination of fixed block signalling and moving block signalling technologies.. The oldest signalling system is known as automatic block signalling and was designed for the system's heavy rail lines: Line 1 Yonge–University, Line 2 Bloor–Danforth and Line 4 Sheppard.
When contacting the local control unit, pilots indicate their information <letter>, where <letter> is the ATIS identification letter of the ATIS transmission the pilot received. This helps the ATC controller verify that the pilot has current information. [4] Many airports also employ the use of data-link ATIS (D-ATIS, introduced in 1996 [2]). D ...
Automatic train stop or ATS is a system on a train that automatically stops a train if certain situations occur (unresponsive train operator, earthquake, disconnected rail, train running over a stop signal, etc.) to prevent accidents.
