The line operated during the weekend early AM hours only between 5:00 AM and 7:00 AM providing riders to National Airport prior to Metro's opening at 7:00 AM.

Most of the lines would travel to various points into Northern Virginia or to Downtown Washington D.C.[1][2] However those routes were later phased out throughout the 1980s to 1990s being simplified or replaced.

[2] The new 13 lines replaced most of routes operating between Pentagon station and Downtown Washington DC on the same day.

Also a new 13F and 13G were introduced to operate between Ronald Reagan Washington National Airport station/Ronald Reagan Washington National Airport and Federal Triangle via Crystal City station and Pentagon station which operates along the 13A, 13B, 13C, 13D, and 13E routing between Pentagon and Downtown DC.

[8][9] Routes 13F and 13G would be retained and still provide early morning weekend service between 5:00 AM and 7:00 AM but could be extended to 8:00 AM if Metro were to change its hours.

[11] WMATA reasons the changes in order to provide connections to additional activity areas and transfers to other lines and minimal ridership was reported at Arlington Cemetery station and on Constitution Avenue west of 14th Street.

[12] In 2016 during WMATA's FY2018 budget, it was proposed to eliminate route 13Y due to low ridership, to reduce costs, and has a high subsidy per rider.

[13][14] According to performance measure it goes as the following for WMATA:[15] On June 25, 2017, route 13Y was eliminated due to low ridership.

The main difference between the 10N and 13Y was the 10N would operate during Friday and Saturday late nights (after midnight) and early morning Sunday service between 6:30 AM and 7:30 AM only.
