Automatic train protection (ATP) is the generic term for train protection systems that continually check that the speed of a train is compatible with the permitted speed allowed by signalling, including automatic stop at certain signal aspects. If it is not, ATP activates an emergency brake to stop the train. [1]
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.
Automatic Train Protection (ATP) is a method of beacon based railway cab signalling developed by British Rail. The system is only installed on the Great Western Main Line between London Paddington and Bristol Temple Meads, and the Chiltern Main Line from London Marylebone to High Wycombe and Aylesbury. History Background Automatic Train Protection notice on a then First Great Western InterCity ...
In inductive system, data is transmitted magnetically between the track and locomotive by magnets mounted beside the rails and on the locomotive. [4]In the Integra-Signum system the trains are influenced only at given locations, for instance whenever a train ignores a red signal, the emergency brakes are applied and the locomotive's motors are shut down.
The Automatic Train Protection sub-system uses coded track circuit technology originally supplied by Rochester, New York-based General Railway Signal when the line was constructed in the 1970s. It is a life-critical system that provides a continuous stream of information to the train regarding the maximum safe speed via the running rails. Speed ...
Automatic train operation (ATO) is a method of operating trains automatically where the driver is not required or required for supervision at most. [1] Alternatively, ATO can be defined as a subsystem within the automatic train control, which performs any or all of functions like programmed stopping, speed adjusting, door operation, and similar otherwise assigned to the train operator.
Interfacing with on-board Automatic Train Protection (ATP) systems, such as the North American Positive Train Control (PTC) system, to extend the amount of time the train can remain in automatic ...
Often referred to as just ATS in railroad operating books, the full name of the system is Intermittent Inductive Automatic Train Stop to differentiate it from mechanical systems being offered at the time. The popularity of ATS as a train protection mechanism fell after the introduction of track coded cab signals in the 1930s.
