Washington Blvd.–Dunn Loring Line

The initial name of the Washington Blvd.–Dunn Loring Line was the Washington Boulevard Line which was the original name since the beginning of service. The Washington Boulevard Line consists of routes 2A, 2C, 2M, and 2W.[2] All 4 routes of the 2 line operated on various schedules, and on different roads. At some point in the 1980s, 2A used to operate between Ballston station and Tysons Corner Shopping Center, until it was replaced by route 2C north of Dunn Loring station. Alongside with these changes, route 2G was introduced, the 2M was discontinued, and the 2W was transferred to the Vienna–Oakton Line. The entire 2 line serves in Ballston station, as it splits into different segments at the neighborhood of Merrifield. Route 2A operates between Ballston and Dunn Loring stations during early morning and late night. Routes 2B and 2G operates the same interval as the 2A, with the extension towards Fair Oaks in Fairfax County. The 2B operates from Monday to Saturday through Fair Oaks Mall, and the 2G operates on weekday peak hour schedules via Flint Hill Office Park and the Gateway Center in Fair Oaks. Route 2C operates in a similar interval as the 2A, by extending the line to Tysons Corner Center. The 2C operates everyday, unlike the other routes in the line.[3] These routes remains the same until December 29, 2013, when the entire 2 line was split to form three new lines. Route 2A became the sole route that operates the original interval, and was renamed the Washington Blvd.–Dunn Loring Line, while the 2B was truncated and transferred to the Fair Oaks–Jermantown Road Line, and the 2C was replaced by the 2T under the Tysons Corner–Dunn Loring Line.[4]

On June 29, 2008, route 2G no longer operates via the Gateway Center.[5] The 2G continues to operate via Flint Hill Office Park to Fair Oaks Mall.

In 2013, WMATA proposed to modify the Washington Boulevard Line.[6] It was proposed that the 2G to be converted into 2B trips, and the 2B to form a new line as the Fair Oaks–Jermantown Road Line. These changes was to reduce bus bunching on the entire line, as the 2G was a redundancy to the 2B.

On December 29, 2013, route 2B splits into two different segments. The eastern segment was replaced by route 2A. Following these changes, route 2A started daily service, while the 2B was truncated to operate between Dunn Loring station and Fair Oaks Mall.[4] Route 2G was discontinued, replaced by routes 2A, and 2B. Route 2C was replaced by the 2T, to operate between Dunn Loring station and Tysons Corner Center.

On September 10, 2020 as part of its FY2022 proposed budget, WMATA proposed to reduce all weekday frequency of route 2A in order to reduce costs and low federal funds.[7]
