Happy Subway Day!
The Interborough Rapid Transit (IRT) subway, New York’s first underground rapid transit network, opened on October 27, 1904 with 28 stations along a 9.1-mile line. That four-track line began at City Hall, ran under Park Avenue South to Grand Central, across 42nd Street to Times Square, and up Broadway to 145th Street.
Initially, the IRT was a privately owned company. It expanded to the Bronx, Brooklyn, and Queens in the ensuing years, and was eventually joined by two competing companies, the Brooklyn-Manhattan Transit Corporation (BMT) and the city-owned Independent Subway (IND). In 1940, these companies were unified and today they comprise the current New York City subway system. It is the largest 24-hour operating subway in the world, with 472 stations, over 800 track miles and a fleet of over 6,000 passenger cars.
