But, with the city's acquisition of the New York, Westchester and Boston Railway and subsequent conversion into the IRT Dyre Avenue Line, such an extension was deemed unnecessary.

[3][4] The station was built underneath preexisting private property for most of its length, passing directly under East 205th Street at its eastern end.

[23] There is clear evidence of water damage and mold due to poor drainage in numerous areas along the platform ceiling, the wall tiles, and to a number of the support columns.

[25][26][29][30] 205th Street station was declared one of the five worst in the system in terms of maintenance and appearance by the New York City Transit Riders Council in 2005,[24][26][27][31] problems which have persisted into the 2010s.

The full-time side at the west (railroad south) end has a turnstile bank, token booth, and two staircases going up to the southeast and northwest corners of East 206th Street and Bainbridge Avenue.

[30][33] Because of the varying topography of the surrounding neighborhood, a single escalator was installed in 1937 in this fare control area, traversing an elevation difference of 25 feet (7.6 m) between the mezzanine and platform.

[39] Another proposal in the 1970s involved extending the Concourse Line to White Plains Road, but financial troubles caused the plan to be aborted.

[39][40] As a result of the planned extension, the two tracks continue east of this station for about 700 feet along 205th Street to Webster Avenue, ending at a concrete wall.

[19][41] The station is located close to several Norwood landmarks, including the New York Public Library's Mosholu Branch; the Montefiore Medical Center and North Central Bronx Hospital, north of the station on East 210th Street; St. Brendan's Church and School; the Valentine–Varian House; and the Williamsbridge Oval, the former site of the Williamsbridge Reservoir.
