  2. Transfer switch - Wikipedia

    en.wikipedia.org/wiki/Transfer_switch

    A transfer switch is an electrical switch that switches a load between two sources. Some transfer switches are manual, in that an operator effects the transfer by throwing a switch, while others are automatic and trigger when they sense one of the sources has lost or gained power. An Automatic Transfer Switch (ATS) is often installed where a ...

    en.wikipedia.org/wiki/Automatic_train_stop

    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. In some scenarios it functions as a type of dead man's switch.

  8. Automatic train operation - Wikipedia

    en.wikipedia.org/wiki/Automatic_train_operation

    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.
