3 Train (Manhattan Exp)

The 3 Seventh Avenue Express is a rapid transit service in the A Division of the New York City Subway. Its route emblem, or "bullet," is colored red since it uses the IRT Broadway–Seventh Avenue Line through most of Manhattan.

The 3 operates at all times. Daytime service operates between 148th Street in Harlem, Manhattan and New Lots Avenue in East New York, Brooklyn, making express stops in Manhattan and all stops in Brooklyn. Late night service short turns at Times Square–42nd Street in Midtown Manhattan.

The 3 train formerly ran to City Hall or South Ferry in Manhattan, and was later rerouted to Flatbush Avenue–Brooklyn College in Brooklyn. In 1983, it was rerouted to New Lots Avenue.

The 3 Seventh Avenue Express currently uses a fleet of R68 Cars
