The 1 Broadway–Seventh Avenue Local is a rapid transit service in the A Division of the New York City Subway. Its route emblem, or "bullet," is colored red, as it uses the IRT Broadway–Seventh Avenue Line for its entire route.
The 1 operates at all times, making all stops between Van Cortlandt Park–242nd Street in Riverdale, Bronx, and South Ferry in Lower Manhattan.
The modern 1 train has always run up to Van Cortlandt Park in the Bronx, but its route below 96th Street has varied over the years. Initially, there were two main service patterns south of 96th Street: a local service to South Ferry in Manhattan and an express service to Brooklyn. The express service was discontinued in 1959. From 1989 to 2005, the 1 ran in a skip-stop service pattern during rush hours, with the 9 providing complementary skip-stop service on the same route. The 1 and 9 trains were rerouted after the September 11 attacks in 2001; although they mostly resumed their normal route by 2002, the 1 train skipped the Cortlandt Street station until 2018.
The 1 Broadway–Seventh Avenue Local currently uses a fleet of R62A Cars
