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".[citation needed]
Train station announcements vary in length and volume. The longest announcement is in Wales, reaching a duration of almost 3 minutes, listing all 39 stations in English and Welsh.[1]
Although train station announcements can seem outdated in addition the platform display and mobile apps, it is necessary for people with vision impairment and for warnings.[citation needed] In Singapore’s MRT, important train announcements are made in the four official languages.[2]
