During the daytime on weekdays, the N runs express between 34th Street–Herald Square in Manhattan and 59th Street in Brooklyn and local elsewhere. Local service in Manhattan is provided by the W, which is internally staffed and scheduled as part of the N. Weekend daytime service is the same as weekday service, except that the N makes all stops in Manhattan between 34th and Canal Streets. During late nights, the N makes all stops along its entire route and uses the Montague Street Tunnel to travel between Manhattan and Brooklyn.
