Train station announcement

Train station announcements are used to inform passengers of the railway timetable of upcoming trains, possible changes such as delays or railway platform changes, and reminders about the non-smoking policies and to keep a safe distance between the tracks and the passengers as well as minding the gap between train and platform. A well-known phrase comes from the London Underground and is the phrase: "Mind the gap".
