Washington Metropolitan Area Transit Service and the nation's leading wireless carriers — AT&T, Sprint, T‐Mobile and Verizon Wireless — have announced the availability of additional wireless voice and data service in the first downtown tunnel segments on the Blue, Orange and Silver lines.
Metro riders can now enjoy uninterrupted wireless access to text, voice and data services when traveling between Metro Center and Stadium-Armory stations. The third underground segment debuting today, Metro Center to Potomac Avenue, provides a seamless connection to the first segment launched in December 2016 between Potomac Ave and the Stadium-Armory tunnel portal.
The addition of the new tunnel segments, extend underground wireless coverage to 3.7 miles of tunnels in each direction on the Orange, Silver and Blue lines.
Metro and the wireless carriers previously installed wireless voice and data service in all underground Metro stations and in April introduced service on the Red Line from Glenmont Station to the Silver Spring Station tunnel portal.
The activation of additional tunnel segments will be announced as collaborative work continues, with all tunnels projected to be covered by December 2020.
