Triangle Line providing express service along Massachusetts Avenue going from Friendship Heights to Federal Triangle. But both routes were eliminated. The Capital Transit Company was later acquired by DC Transit in 1956 which later formed into Metrobus on February 4, 1973. On August 25, 1984, when Friendship Heights station opened, routes N1, N2, and N3 were rerouted to terminate at the newly opened station. A new N6 was later introduced to operate alongside the N2 and N4 but run during the late nights and weekends as a combination to routes N2 and N4 operating in the Wesley Heights Neighborhood alongside the N2 in the clockwise direction (going westbound) but remaining along Massachusetts Avenue going eastbound. In 1996, routes N1 and N3 were eliminated and replaced by route N4 which was extended from its terminus from Westmoreland Circle to Friendship Heights station along Western Avenue. On December 29, 1996, route N6 was eliminated and replaced by routes N2 and N4 which added late night and weekend service at frequencies of every 24–32 minutes during weekday peak periods in the counterclockwise direction, every 36 minutes weekdays between approximately 9:30 AM and 3:30 PM, every 40 minutes weekday evenings after 7:30 PM, and every 50 minutes on Saturdays and Sundays. In 1999, route N6 was reincarnated on its previous routing to replace the N2 and N4 during the late nights and weekends as both routes had low ridership during the post PM Peak hours and weekends. Route N6 would operate for the N2 and N4 as one route to fill the low demand the N2 and N4 had during the times the N6 will operate. On June 25, 2000, route N2 was rerouted to operate along Wisconsin Avenue, Tenley Circle, and Nebraska Avenue instead of operating along Western Avenue as the route overlapped the N4. The reroute N2 would serve the Tenleytown neighborhood and Tenleytown–AU station plus give additional service for routes 30, 32, 34, 35, and 36 along Wisconsin Avenue and route M4 along portions of Nebraska Avenue. Service between Ward Circle and Cathedral and Massachusetts Avenues (to Farragut Square) plus Massachusetts and Idaho Avenues (to Friendship Heights) were unaffected. A new route N3 was also introduced to operate during the weekday peak hours in the peak direction between Friendship Heights station and Federal Triangle via the N4 routing along Western Avenue and Massachusetts Avenue, but turn onto 20th Place and operate
