Thirty-eight Washington Metropolitan Area Transit Authority (Metro)
underground Metrorail stations unveiled new public address systems, this week,
as part of a $7.5 million initiative.
As part of the new public address system, Metro installed
public address speakers on most of the station platform pylons, enhancing the
sound quality inside underground stations.
Additionally, Metro replaced the communications radio system
inside its Rail Operations Control Center. The original
equipment dated back to the beginning of the Metrorail system in 1976 and the
sound system declined in performance and reliability over the course of the
past 32 years.
Metrorail customers will also notice that the new public
address system plays two chimes prior to the start of a station announcement to
get people’s attention.
