Broadway–Seventh Avenue Local

The 9 Broadway–Seventh Avenue Local was a rapid transit service in the A Division of the New York City Subway. Its route emblem, or "bullet", was colored red, since it used the Interborough Rapid Transit Company (IRT)'s Broadway–Seventh Avenue Line for its entire route.

The 9 operated during rush hour periods from 1989 to 2005, as a variant of the 1, providing service between Van Cortlandt Park–242nd Street in Riverdale, Bronx, and South Ferry in Lower Manhattan. The 1 ran in a skip-stop service pattern during rush hours, with the 9 providing the complementary skip-stop service on the same route. The 9 was temporarily suspended between 2001 and 2002 due to severe damage to the Broadway–Seventh Avenue Line caused by the September 11 attacks, and was permanently discontinued in 2005 as a result of a decrease in the number of riders benefiting. The 9 designation was also used for a shuttle train on the IRT Dyre Avenue Line between 1941 and 1967.

History
The 9 designation was originally used for the Interborough Rapid Transit Company's (IRT) Dyre Avenue Line. It served the former New York, Westchester and Boston Railway between Dyre Avenue and East 180th Street, connecting to the IRT White Plains Road Line at the latter station. When a connection between the Dyre Avenue Line and the White Plains Road Line opened in 1957, daytime shuttle service was replaced with through service as the 2. From 1957 until 1967, the nighttime Dyre Avenue Shuttle continued to use the number 9. The shuttle was relabeled SS in 1967, and then renamed as part of the 5, the same as the through service on the line through East 180th Street to Dyre Avenue. in August 1972.
