Introduction

Grupo México, a global railway industry giant, is joining competitors to secure operations of Belgrano Cargas and San Martín railway lines in Argentina. Decisions are expected by March of the following year.

Grupo México’s Background and Relevance

Grupo México is a prominent player in the global railway sector, with operations spanning logistics, infrastructure, and mining. The company currently manages the primary railway line in Mexico and Florida, with plans to open one in Texas. Their railway networks transport over 100 million tons, partnering with Union Pacific, the world’s largest railway line in the sector.

Targeted Argentine Railway Lines

The Belgrano Cargas and San Martín lines are the focus of Grupo México’s interest. The Belgrano Cargas, traversing Santa Fe, Entre Ríos, Córdoba, Tucumán, Salta, and Jujuy provinces, passes through the significant grain export port of San Lorenzo. The San Martín line connects Buenos Aires to the port, crossing La Pampa, Mendoza, San Luis, and southern Córdoba.

Competition for Railway Operations

Several entities are interested in these lines. Mining companies and agroexporters, who formed a consortium to jointly administer the railway, view Belgrano Cargas as highly desirable for its export sector appeal. The estimated investment for Grupo México’s entry is around $3,000 million, targeting control of all tranches and operational areas to subsequently serve energy, mining, and agroexport sectors.

Cereal Industry’s Interest

The major cereal companies in Rosario’s port have agreed to form a joint offer for the Belgrano Cargas train. Their goal is to reduce production costs by approximately 20% due to the logistics’ weight. Bunge, Cargill, ACA, AGD, Dreyfus, and Cofco have united to achieve this.

Mining Sector’s Interest

Mining companies are also interested in the Belgrano Cargas line to transport litium, gold, copper, and silver production from Argentina’s northwest towards ports.

Investment and Timeline

The sector estimates that Grupo México’s entry could require an investment of $800 million for railway operations. The formal privatization process began in February of this year, with a tender expected by late November or early December. Decisions are anticipated by March.
