At the beginning of 2026, a consortium led by Aldesa from Spain and deeply empowered by CRCC successfully won a heavyweight contract worth 173 million US dollars, officially responsible for the construction of the complete operational infrastructure for the Kretaro Irapuato passenger dedicated line. This is not only another major milestone for the project after the civil engineering, but also marks the deep participation of international contractors with Chinese heritage in another national strategic project besides the Maya Railway in Mexico. With the construction of gas stations, maintenance bases, and other major rear areas, this golden corridor that carries the hope of Mexican industry is accelerating from a blueprint to a reality.

Building the West Mexico China Railway Triangle

This bid is a deep integration of the industrial chain across the Eurasian continent. Aldesa is not fighting alone, behind it stands CRCC, a strategic shareholder who has just completed its equity restructuring. As one of the world's largest engineering contractors, CRCC has not only injected strong capital into Aldesa, but also brought world leading railway construction technology and management experience.

In this newly established joint venture, Aldesa will collaborate with its affiliated companies Aldesem, Proacon, and Coalvi, and specifically introduce the powerful Mexican contractor Jaguar. This iron triangle model of Spanish general contracting, Chinese technology/funding, and local execution in Mexico not only avoids the entry risks of pure foreign-funded enterprises, but also utilizes CRCC's global supply chain advantages to significantly reduce the procurement costs of building materials and equipment. Moreover, through Jaguar's familiarity with local labor laws and community relations, non-technical obstacles have been cleared for the project.

6.7 billion US dollars grand plan launched

The $173 million operational infrastructure contract is just one piece of the massive puzzle for the Kretaro Irapuato project. As early as November 2025, a consortium led by Portugal's Motta Engier had taken the lead in winning the first major civil engineering project of the line. Now, with the establishment of operational facility construction companies, the project has officially entered the fast lane of parallel civil engineering and logistics.

The project is 108 kilometers long and adopts a dual track design, with a maximum speed that can meet the efficient commuting needs of Baj í o Industrial Zone - the heart of Mexico's automobile manufacturing industry, where giant factories such as Volkswagen and General Motors are located. The total budget of the project is as high as 6.7 billion US dollars, fully managed by Attapi, a newly established federal agency by the Mexican government in January 2026. The establishment of Attapi aims to break down departmental barriers and coordinate national railway planning. Its debut was this passenger line, which is regarded as the industrial artery of Mexico.

To cope with complex geological conditions, the contractor plans to introduce multiple large-diameter earth pressure balance shield machines, which is CRCC's specialty. It is expected that after the full line is opened in 2029, this railway will shorten the travel time between Mexico City and northern industrial towns to less than 2 hours, not only restoring intercity passenger transportation that has been interrupted for decades, but also reducing logistics costs for Mexico's manufacturing industry by about 15%.

From the Maya Railway to the Queretaro Special Line, Chinese infrastructure companies are transforming from simple construction companies to integrated partners in investment, construction, and operation. CRCC's controlling stake in Aldesa actually opens a hidden and spacious door for Chinese standards, Chinese equipment, and Chinese capital to enter the backyard of the North American Free Trade Zone. With the gradual injection of $6.7 billion, a steel Silk Road connecting the Gulf of Mexico and the Pacific coast is gradually becoming clear.Editor/Cheng Liting
