The New York City boroughs of Brooklyn, Queens, Staten Island and the Bronx are home to 6.6 million people. Many of them are poorly served by the city’s century-old, Manhattan-centric transit system.

Interborough Express
Running 24 miles on existing track from Co-op City in the Bronx to Bay Ridge in Brooklyn, the Triboro would be an above-ground rail line connecting 17 subway lines and 4 commuter lines.
