Mexico is positioning its southern rail corridor across the Isthmus of Tehuantepec as a faster alternative for shipping goods from Asia to the U.S. amid Panama Canal water shortages. South Korea’s Hyundai has already used the route, with major U.S. automakers expressing interest. The government is investing $540 million to expand ports and rail lines, aiming to establish a full freight corridor. The route cuts transit time to the U.S. by several days compared to Panama or Canadian routes, boosting southern Mexico’s logistics potential.
