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 , since 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 through 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 the complementary skip-stop service on the same route. The 1 and 9 trains were rerouted after the September 11 attacks in 2001; although they had mostly resumed their normal route by 2002, the 1 train skipped the Cortlandt Street station until 2018. Service history Early service When the New York City Subway began operation between 1904 and 1908, one of the main service patterns was the West Side Branch, which the modern 1 train uses. Trains ran from Lower Manhattan to the 242nd Street station near Van Cortlandt Park, using what is now the IRT Lexington Avenue Line, 42nd Street Shuttle, and IRT Broadway–Seventh Avenue Line. There was both local and express service with express trains using the express tracks south of 96th Street. Some express trains ran to Atlantic Avenue in Brooklyn via the Joralemon Street Tunnel during rush hours while all other trains terminated at City Hall or the South Ferry outer loop. On November 15, 1906, a petition with 20,000 signatures was sent to the Rapid Transit Commission to request the restoration of express service on the third track north of 96th Street. Residents of Inwood, Marble Hill, and Kingsbridge joined Washington Heights residents in requesting this service to speed their commutes. After receiving that petition, on November 16, the Rapid Transit Commission ordered the Interborough Rapid Transit Company (IRT) to extend express service from 96th Street to 137th Street in three days. Limited express service was inaugurated on November 19, 1906, operating daily, except Sundays and holidays, between 7:20 and 8:58 a.m. and 4:54 and 6:18
