NYCTA J/M/Z Lines

The J Nassau Street Local and Z Nassau Street Express are two rapid transit services in the B Division of the New York City Subway. They are colored terra cotta brown, since they use the BMT Nassau Street Line in Lower Manhattan. The J runs at all times while the Z operates only during rush hours in the peak direction; both services use the entire BMT Archer Avenue, Jamaica, and Nassau Street lines between Jamaica Center – Parsons/Archer, in Jamaica, Queens, and Lower Manhattan (via the Williamsburg Bridge between Brooklyn and Manhattan). On weekdays, trains run express in Brooklyn between Myrtle Avenue and Marcy Avenue in the peak direction, bypassing three stations. During rush hours also in the peak direction, the J and Z form a skip-stop pair east of Myrtle Avenue.
