Note about Railway Companies and their Operations
Prior to the subways, elevated and surface lines were heavily utilized for commuters in New York City. While the first subway was officially launched in 1904 by the Interborough Rapid Transit (IRT), it is important to remember that elevated and surface lines were not completely replaced by this new form of rail transit.
As you can see below in this map from the early 20th century, the subway co-existed with elevated and surface lines.

In addition, while many of the rail companies listed in this section operated subways, many also operated elevated and/or surface rails prior and after 1904. For instance, the Brooklyn Rapid Transit Company was already operating elevated and surface rails long before the introduction of the subway in New York. As you can see from this map from approximately 1903, the existing commuter lines were far-reaching throughout the borough before the subway.

With the subway's introduction in 1904, BRT would later become involved in creating the underground systems. For instance, 1914's "Rand, McNally's & Co.'s map of dual subway system" shows both the existing and proposed lines for elevated rails and subways that were being operated by the BRT and IRT.
Today, while many people often refer to the MTA's lines as the "NYC Subway," these lines constitute a mixture of:
- elevated rails
- Example:
- 7 line is on an elevated track in Queens but underground in Manhattan
- Example:
- surface lines, and
- Example:
- Staten Island's SIR
- Example:
- underground subways
- Example:
- N line is underground in Manhattan, but becomes elevated in Brooklyn and Queens
