Standards for Frequency, Volume, Duration and Repetition of Announcements in MRT Trains and Stations

Mr Gerald Giam Yean Song asked the Minister for Transport (a) whether the Ministry sets standards across rail operators for the frequency, volume, duration and repetition of announcements in MRT trains and stations; and (b) if so (i) whether the average proportion of journey times occupied by announcements has been assessed for each rail line and (ii) whether non-critical reminders can be shifted to visual channels to provide a more comfortable commuter experience.

Other than announcements related to service disruptions and emergencies which must be made at prescribed frequencies, rail operators have the flexibility to decide on the frequency, volume and duration of announcements in stations and onboard trains. This is so that they can make adjustments based on the operating context, site conditions including ambient noise which can vary across time and location, as well as commuter profile.

Not all audio announcements can be shifted to visual channels, as some commuters may not be in a position to view the display panels. Audio announcements also remain essential for visually impaired commuters.
