From Wikipedia becuase it is easier then typing it out myself
The
Independent Subway System (
IND or
ISS), formerly known as the
Independent City-Owned Subway System (
ICOS) or the
Independent City-Owned Rapid Transit Railroad, was a
rapid transit rail system in
New York City that is now part of the
New York City Subway. It was first constructed as the "
Eighth Avenue Line" in
Manhattan in 1932.
One of three rail networks that became part of the modern New York City subway, the IND was intended to be fully owned and operated by the municipal government, in contrast to the privately operated or jointly-funded
Interborough Rapid Transit Company (IRT) and
Brooklyn-Manhattan Transit Corporation (BMT) companies. It was merged with these two networks in 1940.
The original IND service lines are the modern subway's
A through
G lines. In addition, the BMT's
R now runs partly on IND trackage, and the
Rockaway Park Shuttle and
V supplement the
A and
F, respectively. For operational purposes, the IND and BMT lines are referred to jointly as the
B Division.
The
Brooklyn-Manhattan Transit Corporation (
BMT) was an
urban transit holding company, based in
Brooklyn,
New York City,
United States, and incorporated in 1923. It is now the BMT Division of the
New York City Subway. Together with the
IND, it is operationally described as
B Division. The original BMT routes have the letters from
J to
R, as well as the
Franklin Avenue Shuttle (
S). The
IND's
B,
D and
F partly use BMT trackage, and the
W and
Z supplement the
N and
J.
