New Public Address System For Metro Stations

Play associated audio

Metro has started using a new public address system in dozens of underground rail stations in hopes of improving poor sound quality.

Passengers have long complained about inaudible messages in the cavernous concrete stations, and Metro hopes a $7.5 million upgrade fixes the problem. The new public address system installed in 38 stations includes speakers on most station platform pylons and walls. Two chimes are played just before an announcement to get passengers' attention.
