Maglev

Maglev (derived from magnetic levitation) was a system of overland, underground, and transoceanic transport used on many Federation planets, including Earth. 

In 2045, the Translantic Maglev Tunnel was completed, connecting Montauk, New York, and County Kerry, Ireland. ( Timeline)

The many facilities of the Empire State Hospital Complex, on Roosevelt and Manhattan Islands in New York City were connected by an underground private maglev network. 

After her college boyfriend broke up with her in 2273, Carolyn Adiwoso hopped on a maglev from New York City to San Francisco to cry on her cousin Sabartomo's shoulder. (Star Trek: Shadowstar Station: "Promised")


 * It has not yet been seen, either in aired or published Trek, to what extent Earth's global maglev transportation network was made obsolete by site-to-site transporters.
