9 was a designation given to several services of the New York City Subway.
From 1917, Brooklyn–Manhattan Transit Corporation (BMT) services on the IRT Flushing Line were assigned the number 9, used on maps but not on trains; IRT services used the designation 7 instead. When the joint BMT-IRT operation on the Flushing Line, provided for under the Dual Contracts, was discontinued, the BMT designation 9 was also canceled.
The 9 designation was originally used for the Interborough Rapid Transit Company (IRT)'s Dyre Avenue Line upon its opening in 1941 between Dyre Avenue and the East 180th Street platforms of the former New York, Westchester and Boston Railway, 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 till 1966, the nighttime Dyre Avenue Shuttle continued to use the number 9. Since 1967, the Dyre Avenue Shuttle runs during late night hours, but now carries the number 5, the same as the through service on the line.
The second and most recent usage of the 9 designation was a skip-stop service to complement the 1 local train on the IRT Broadway–Seventh Avenue Line as the 9 Broadway–Seventh Avenue Line Local. Beginning at 6:30 AM on Monday, August 21, 1989, the services were coordinated as the 1/9 and both ran between Van Cortlandt Park–242nd Street and South Ferry. The skip-stop operation was north of 137th Street.
