A staircase leads to the exit at the 47–50 Streets Rockefeller Center subway station in Manhattan. The station serves the B, D, F, and M lines.

The Lexington Avenue–63rd Street station in Manhattan, part of the IND and BMT lines of the New York City Subway, is shown here in its distinctive red-tiled design. Opened in 1989 as part of the 63rd Street Tunnel project, the station serves the F and Q trains, linking the Upper East Side to Queens and the Second Avenue Subway. Its sharply linear geometry and long central platform exemplify late-20th-century transit architecture, emphasizing function and durability. The bright red glazed brick walls contrast with the metallic fixtures and fluorescent ceiling strips, creating a visual rhythm typical of New York’s underground infrastructure during the city’s major transit expansion era.
