New Vertiform City was a holographic city created by the USS Enterprise-D's computer in 2370.

The city was a metonymic representation of an area abundant in vertion particles. New Vertiform City was created by the computer as a replacement for Vertiform City, namely Tambor Beta-6, a white dwarf star, which had proven to be an insufficient source of the particles.

At first, New Vertiform City's real-world counterpart was the Cordannas system, the next nearest white dwarf star system, but when Data showed the conductor a shortcut to New Vertiform City, he was actually redirecting the ship's course to the MacPherson Nebula. (TNG: "Emergence")

Though the train arrived in New Vertiform City, the city was never actually shown on screen.
