High Quality Content by WIKIPEDIA articles! The BMT Broadway Line is a rapid transit line of the B Division of the New York City Subway in Manhattan, New York City, United States. As of 2010, it is served by three services, all colored yellow: the Q on the express tracks and the N R on the local tracks. The line is often referred to as the "N and R", since those were the only services on the line during the long years that the Manhattan Bridge south tracks were closed for rebuilding. The Broadway Line was built to give the Brooklyn Rapid Transit Company (later the Brooklyn–Manhattan Transit Corporation) access to Midtown Manhattan.
