History
Planning for Metro began with the Mass Transportation Survey in 1955, which attempted to forecast freeway and mass transit systems sufficient to meet the needs of 1980. In 1959, the study's final report recommended two rapid transit lines which anticipated subways in downtown Washington. Because the plan called for extensive freeway construction within the District of Columbia, alarmed residents lobbied for federal legislation creating a moratorium on freeway construction through July 1, 1962. The National Capital Transportation Agency's 1962 ''Transportation in the National Capital Region'' report anticipated much of the present Red Line route, with the Red Line following the
Baltimore and Ohio Railroad

right-of-way between Silver Spring and Rockville instead of a direct route between
Bethesda and Rockville.
With the formation of WMATA in October 1966, planning of the system shifted from federal hands to a regional body with representatives of the District, Maryland, and Virginia. Congressional route approval was no longer a key consideration. Instead, routes had to serve each suburban jurisdiction to assure that they would approve bond referendums to finance the system. Because the least expensive way to build into the suburbs was to use existing railroad right-of-ways, the Red Line took much of its present form, except that it continued to feature a further link between its two stems along the Baltimore and Ohio Railroad right-of-way.
By 1969, WMATA had decided on the current routing and stations, except for the extension beyond Rockville to Shady Grove. Montgomery County officials opposed ending the Red Line in downtown Rockville, saying it would cause congestion in the area and use scarce vacant land for a storage yard.
Metro decided to propose to extend the red line one more station to Shady Grove and the U.S. Department of Transportation conditionally approved funding for the extension on July 26, 1975.
Construction on the Red Line began with a groundbreaking ceremony at

and required that the Red Line tunnel under that valley, the tunnel in turn caused both the
Dupont Circle and Woodley Park stations to be built further underground. The Red Line was proposed to tunnel under Yuma Street from Connecticut Avenue to Wisconsin Avenue, but local residents sued and that court case delayed construction of the tunnel for two years, then WMATA finally won the right to build the tunnel there.
Service on the Red Line (and the Metro as a whole) began on March 27, 1976, with operation between
Farragut North and
Rhode Island Avenue.
Gallery Place's opening was delayed due to a court order regarding lack of handicapped access, but it opened in the middle of the line on December 15, 1976.
The western end of the line was extended one station to
Dupont Circle on January 17, 1977, three stations to
Van Ness–UDC on December 5, 1981, five stations to
Grosvenor–Strathmore on August 25, 1984, and four stations to
Shady Grove on December 15, 1984.
The eastern end was extended one station from
Rhode Island Avenue-Brentwood to
Brookland-CUA on February 3, 1978. The eastern end was extended three stations to
Silver Spring on February 6, 1978—which added Maryland to the system for the first time — two stations to
Wheaton on September 22, 1990, and one station to
Glenmont on July 25, 1998, completing the line.
The only time the Red Line shared tracks with another line was from January 27, 1997, to September 17, 1999, when the
Green Line Commuter Shortcut used Red Line tracks from
Brookland–CUA to
Farragut North. A short time after the Green Line branch north of
Fort Totten opened in the early 1990s, the "Green Line Commuter Shortcut" began as a six-month experiment. Passengers could board the Green Line between
Greenbelt and
West Hyattsville and travel as far as Farragut North without having to transfer; the trains bypassed Fort Totten via a single-track spur between the West Hyattsville and Brookland–CUA stations. Due to its success, the shortcut continued until the mid-city portion of the Green Line was completed in 1999.
The
NoMa–Gallaudet University station (formerly New York Ave–Florida Ave–Gallaudet University), located between
Union Station and
Rhode Island Avenue–Brentwood, opened on November 20, 2004. It was the system's first

(i.e., a new station built between existing stations).
In November 2010, the WMATA authorized $37 million in capital improvements on the Red Line, a part of $212 million of work on the Red Line scheduled for 2010 to 2014.
In April 2012, a 1,200-car parking garage opened at the Glenmont station, joining the existing 1,700-car garage. Construction on the project, funded by the state of Maryland, began in December 2009.
From March 26, 2020, until June 28, 2020, trains were bypassing , , and stations due to the
2020 coronavirus pandemic.
All stations were reopened beginning on June 28, 2020.
From September 11, 2021, to January 16, 2022, the Metro station was closed due to the Rockville Canopy Replacement Project.
On February 25, 2022, WMATA opened a new entrance, on the east side of Rockville Pike and a new elevator and staircase to platform at the
Medical Center station, eliminating the need for thousands of daily riders who emerge from the station on the west side of the Pike to cross the busy six-lane road to reach the
Walter Reed National Military Medical Center. In September 2009, Montgomery County applied for a $20 million federal grant, seeking to begin construction in 2011, but the project was not approved until 2013. Construction began in December 2017. The $68 million project, mostly funded by from the
Department of Defense, also includes new deep elevators, better surface bicycle, and pedestrian facilities, a pedestrian tunnel under Rockville Pike, and an extension of the left-turn lane on southbound MD 355 that opened in late 2021.
Incidents and accidents
2004 Woodley Park accident

On November 3, 2004, an out-of-service Red Line train rolled backward into the
Woodley Park station and hit an in-service train stopped at the platform. Twenty people were injured. A 14-month investigation concluded that the train operator was most likely not alert. Safety officials estimated that at least 79 would have died had the train been full. The train operator was fired and Metro officials agreed to add rollback protection to more than 300 rail cars.
2009 train collision

On June 22, 2009, at 5:03 p.m., a six-car train collided with and
telescoped onto a stationary train between the
Takoma and
Fort Totten Metro stations. Eight passengers and a train operator were killed in the collision and at least 70 people were injured. It is the deadliest accident in the history of the Washington Metro.

Chronology
Dates on which portions of the Red Line opened for service.
Route

The Red Line begins above ground at Shady Grove, and parallels
CSX Transportation's
Metropolitan Subdivision (served by
MARC Brunswick Line trains) to south of
Twinbrook. The route then enters a tunnel and curves west to run under
Rockville Pike at
White Flint. Until
Tenleytown, the line follows the route of Rockville Pike and
Wisconsin Avenue in a tunnel, except for a bridge over the
Capital Beltway (I-495). The tunnel curves east at Tenleytown into Yuma Street to reach the
Van Ness–UDC station, curving south there to travel under
Connecticut Avenue through south of
Farragut Square. A curve under
Lafayette Park takes the tunnel east under G Street Northwest through the
Metro Center and
Gallery Place stations.

, the line runs southeast, turning east again at D Street to reach
Union Station. There it turns north and surfaces next to Union Station's platforms, follows the Washington Terminal yard tracks north to
Brentwood where the line turns northwestward and again joins CSX Transportation's Metropolitan Subdivision tracks, running in a unique
gauntlet

Internally, WMATA calls the Red Line the Shady Grove Route (A) and the Glenmont Route (B), which meet at
Metro Center.
The Red Line needs 44 trains (10 eight-car trains and 34 six-car trains, consisting of 284 rail cars) to run at peak capacity. Trains run most frequently during morning and evening rush hours (nominally four to eight minutes apart) and least frequently after 9:30 p.m. (nominally 15 to 18 minutes apart).
