The New Andasar Subway is the public underground train system of New Andasar on Antiga Prime. Its rail lines contain cargo cars large enough to accommodate even vehicles the size of siege tanks. The entire city was connected by this railway.
During the Defenders of Man Insurgency, New Andasar was overrun by feral zerg, and many of the subway exits were blocked by creep. When Agent Nova Terra of the Terran Dominion arrived at the city to reverse parts of her mind wipe, Reigel noted that if the subway exits were cleared the rail line could be used to ferry her troops around the city.
