ATPn.²

Brit.

/ˌeɪtiːˈpiː/, U.S.

/ˌeɪˌtiˈpi/

Origin: Formed within English, as an initialism. Etymon: English automatic train protection.

Etymology: Initialism < automatic train protection.

Automatic train protection, a system designed to stop a train automatically if the driver ignores a signal warning, speed restriction, etc.
