The Lenox Avenue Line begins at the Harlem–148th Street station, which was formerly known as 148th Street–Lenox Terminal. After the terminal, a track merges from the Lenox Yard, and the line heads south under Lenox Avenue. At 142nd Street Junction, the IRT White Plains Road Line merges (with an at-grade crossing between the northbound Lenox track and the southbound White Plains track), carrying through service from the Bronx.
At the north border of Central Park is the final stop on the line, Central Park North–110th Street. From there the line curves southwest under the North Woods and North Meadow of Central Park, being one of three lines to pass under the park (the other two being the IND 63rd Street Line and the BMT 63rd Street Line). It heads west under 104th Street, then turns southwest and south to run underneath the IRT Broadway–Seventh Avenue Line, passing under part of the northbound platform at 103rd Street. After the center express track on the Broadway–Seventh Avenue Line ends by connecting to the two local tracks, the Lenox Avenue Line rises to become the two express tracks, with double crossovers to each local direction. The four-track Broadway–Seventh Avenue line then continues south through 96th Street, an express station and transfer point.
The line opened south of 145th Street just after midnight on November 23, 1904, as part of the IRT's original system. It was known as the East Side Subway or East Side Branch at the time, as it was the spur of the main line to the east side. The first train ran from the line onto the IRT White Plains Road Line (known as the West Farms Branch or the West Farms Extension) just after midnight on July 10, 1905. Soon after the line opened, it was speculated that it would bring prosperity to Harlem.
Originally the line north of the 142nd Street Junction was only intended to be a yard lead to Lenox Yard, and sometime afterwards it was suggested to add a station at 145th Street.
The line has always carried trains of two service patterns, currently designated 2 and 3. Prior to February 6, 1959, 3 trains switched to the local on the IRT Broadway–Seventh Avenue Line north of 96th Street. Afterwards, all trains running from the Lenox Avenue Line ran express.
From March 2 to October 12, 1998, the tunnel that carried the 2 and 3 services was reconstructed along with the cracked invert (tunnel floor). This was done to correct a major water problem that had existed for many years due to underground streams located around the Lenox Avenue area that caused extensive water damage and seepage problems, resulting in extensive and severe delays due to track and roadbed flooding. The project cost $82 million. Many 2 trains were rerouted via the IRT Lexington Avenue Line, while the 3 trains were rerouted to the 137th Street–City College station on the IRT Broadway–Seventh Avenue Line. Each of the two tracks that carried both the 2 and 3 services were alternately taken out of service, the 116th Street Station was closed, and supplemental shuttle bus service connecting to other lines in the area were provided for much of this time.
From 1995 until 2008, the line's two northernmost stations, Harlem–148th Street and 145th Street, were served by shuttle buses during the late-night hours. Full-time service was restored on July 27, 2008.
The entire line is located in Harlem.
