12. Oldest Subway Line: The IRT Line

City Hall Subway Station

The IRT subway line was the first to open in October 1904, and went from City Hall to Grand Central Terminal, cut across 42nd Street to Times Square, and went on north to 145th Street. Though the IRT subway stations all opened on the same day, the most famous is the decommissioned City Hall subway station.

City Hall Station was built as the “crown jewel” of the new New York City subway line. Though it’s been out of service for over 75 years, you can still catch a glimpse of it today. Trains still travel through the station the 6 line in order to turn around.
