The Interoceanic Train, inaugurated in 2023 under former President Andres Manuel Lopez Obrador, forms part of the broader Interoceanic Corridor project.
The initiative was designed to modernize the rail link across the Isthmus of Tehuantepec, connecting Mexico's Pacific port of Salina Cruz with Coatzacoalcos on the Gulf Coast.
The Mexican government has sought to develop the isthmus into a strategic trade corridor, expanding ports, railways and industrial infrastructure with the goal of creating a route that could compete with the Panama Canal.
The train service is also part of a broader push to expand passenger and freight rail in southern Mexico and stimulate economic development in the region.
