During the afternoon peak hours, routes N2 and N4 utilize the 2016 New Flyer XE40 buses WMATA owns (1001).

The N2 and N4 originally began operating under streetcar lines by the Washington Railway & Electric Company in the 1900s.

[2] When the Capital Transit Company took over the Washington Railway & Electric Company, route N4 was rerouted to Glen Echo Park along the Maryland side of Massachusetts Avenue and Goldsboro Road.

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.

Passengers would have to walk a short distance to the Mazza Gallerie Metro station entrance as a result.

But many residents called Erion's statement pathetic and that both WMATA and DDOT have total disdain for both Glover Park and Wesley Heights.

DDOT's Steve Strauss told neighbors that in making the changes, both his agency and WMATA assumed the community "wanted to maintain the Spring Valley connection.

"[12] Other Glover Park residents argued that the impacts of inclement weather and insufficient lighting make some of the streets no longer served by the N2 difficult and potentially dangerous.

[12] The Advisory Neighborhood Commission passed a resolution asking DDOT and WMATA to restore the N2 route prior to the September 2011 changes Commissioners reasoned that the change was made so quickly in the first place that the agencies should be able to just switch them back.

If the buses are "inter-lining," it is possible that, for instance, when N2 bus reaches the end of its route, it could become another line entirely.

This gave Wesley Heights and Glover Park residents access to Tenleytown–AU station as the September 2011 reroute abruptly taken away service to Tenleytown.

Riders can ride the N4 up to 20th Street and transfer to the H1, L1 or S1 to Potomac Park/Foggy Bottom–GWU station and routes 30N, 30S, 32, 33, and 36 to Federal Triangle.

[19] A modified schedule and all weekend service resumed on August 23, 2020 with routes N2 and N4 remaining suspended.
