20th century The station opened on July 1, 1977. Its opening coincided with the completion of of rail between
National Airport and
RFK Stadium. Orange Line service to the station began upon the line's opening on November 20, 1978. In 1979, the D.C. Armory requested that the station name be changed to "Starplex" for the Stadium Armory Complex, but that request was ignored by the Metro Board. Stadium–Armory would also serve as the eastern terminus of the Blue Line from its opening through the opening of its extension to on November 22, 1980.
21st century The station was supposed to be the Silver Line's eastern terminus, but in December 2012, due to safety concerns regarding a
pocket track between this station and and
Benning Road, Metro officials decided to extend the line into nearby
Prince George's County, Maryland to
Largo, which is the eastern terminus of the Blue Line. Silver Line service at Stadium-Armory began on July 26, 2014. Between May 28 and September 5, 2022, all Orange Line trains were terminating at Stadium–Armory station due to the Platform Improvement Project which closed stations north of Stadium–Armory station. On weekends, all Blue and Silver Line trains were terminating Stadium–Armory while Orange Line trains were cut back to
Ballston–MU due to aerial structure repairs along the D route. On September 21, 2015, a
transformer caught fire near the station, causing severe delays. The reduced power as a result of the loss of the transformer caused WMATA to implement strategies to combat congestion in the system. This included having Orange and Silver line trains skip the Stadium–Armory station during rush hours, but service had been restored as of November. == References ==
