The
M Sixth Avenue Local is a
rapid transit service in the
B Division of the
New York City Subway. Its route emblem, or "bullet", is colored since it uses the
IND Sixth Avenue Line in
Manhattan. On weekdays, the
M operates between
71st Avenue in
Forest Hills, Queens, and
Metropolitan Avenue in
Middle Village, Queens, via the
IND Queens Boulevard Line and
Sixth Avenue, the
Williamsburg Bridge, and the
BMT Jamaica and
Myrtle Avenue lines. This makes the
M the only service that travels through the same borough via two different, unconnected lines.
