    en.wikipedia.org/wiki/Automatic_train_stop

    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.

  3. Anti-lock braking system - Wikipedia

    en.wikipedia.org/wiki/Anti-lock_braking_system

    An anti-lock braking system (ABS) is a safety anti-skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses. [1] ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over the ...

    The most common use case for the ATS system was to alert the railroad engineer of an impending hazard and if the alert was not acknowledged, stop the train by means of a full service application of the brakes. When attached to signals the shoe would be energized when the signal was displaying a clear indication. Any other signal indication ...

    ATS system. The ATS system is commonly integrated within most of the CBTC solutions. Its main task is to act as the interface between the operator and the system, managing the traffic according to the specific regulation criteria. Other tasks may include the event and alarm management as well as acting as the interface with external systems.

    D-ATC indicator used on the E233 series trains. The digital ATC system uses the track circuits to detect the presence of a train in the section and then transmits digital data from wayside equipment to the train on the track circuit numbers, the number of clear sections (track circuits) to the next train ahead, and the platform that the train will arrive at.
