9 (New York City Subway service)

For the former Brooklyn–Manhattan Transit Corporation 9 service, see IRT Flushing Line.

9 was a designation given to several Interborough Rapid Transit Company (IRT) services of the New York City Subway.

Dyre Avenue Line (1941–1966)

9 DYRE AVE

The 9 designation was originally used for the IRT 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.

Broadway – Seventh Avenue Line skip-stop service (1989–2005)

1989–2005 bullet

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.

Midday skip-stop service was discontinued in 1994, but remained during peak hours. By this time, skip-stop service assigned the following stations to the 1 train only:

• 238th Street
• 215th Street
• Dyckman Street
• 157th Street

and the following stations to the 9 train only:

• Marble Hill – 225th Street
• 207th Street
• 145th Street

After the September 11, 2001 attacks, 1 trains had to be rerouted since the IRT Broadway – Seventh Avenue Line ran directly under the World Trade Center site and was heavily damaged in the collapse of the Twin Towers. The 1 ran only between Van Cortlandt Park – 242nd Street and 14th Street, running local north of 96th Street and express south of there; the 9 service and skip-stop service were suspended at this time. 1 trains returned to South Ferry, and skip-stop service was restored on September 15, 2002.

As a result of a decrease in the number of riders benefiting from the 9 and skip-stop services, the MTA announced their elimination in mid-2004 and approved it in early 2005. The last 9 train ran on May 27, 2005 and the 1 now makes all stops on the IRT Broadway-Seventh Line.

May 31, 2005 was the first weekday the 9 did not run
