The 2 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 since it uses the IRT Broadway – Seventh Avenue Line through most of Manhattan. The 2 operates at all times between 241st Street in Wakefield, Bronx and Flatbush Avenue – Brooklyn College in Flatbush, Brooklyn, making all stops in the Bronx and Brooklyn. Daytime 2 service runs express in Manhattan; late night service operates local. The service operates via White Plains Road in the Bronx, Lenox Avenue and Seventh Avenue in Manhattan and Eastern Parkway and Nostrand Avenue in Brooklyn. Limited rush hour service also operates between the Bronx and New Lots Avenue in East New York, Brooklyn due to capacity issues at Flatbush Avenue. == Service history == The first section of what became the current 2 entered service on November 26, 1904 from at temporary 180th Street - Bronx Park terminal via the West Farms El to 149th Street - 3rd Avenue.
