was discontinued, and 191st Street was no longer a skip-stop station. By this time, skip-stop service assigned the following stations to the 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, 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. It later ran to New Lots Avenue via the IRT Eastern Parkway Line, running local on that line, as well as south of 96th Street, replacing the train, which ran between Harlem–148th Street and 14th Street; the 9 service and skip-stop service were suspended at this time. trains returned to South Ferry, and skip-stop service was restored on September 15, 2002. On April 27, 2004, it was announced that New York City Transit was considering eliminating 9 and skip-stop service due to long wait times, and as a result of a decrease in the number of riders benefiting. The MTA estimated that eliminating skip-stop service only added to 3 minutes of travel time for passengers at the northernmost stations at 242nd Street and 238th Street, while many passengers would see trains frequencies double, resulting in decreased overall travel time because of less time waiting for trains. It planned on making a decision in the summer, and approved the change on January 11, 2005. The 9 train was discontinued on May 27, 2005 and the 1 now makes all stops on the IRT Broadway–Seventh Avenue Line.

Stations Stations in green and stations in blue denote stops served by the 1 and former 9, respectively, during rush hours. At all other times, the 1 ran local and now runs local at all times.
