To design in-house and manufacture railway track equipment of the highest quality, operating under strict international standards — ISO, AAR, EN/UIC — with full supply chain capability, from rough machining to final manufacturing.
To become a global reference in integrated railway solutions: innovation, globally certified standards and full plant capability, leading the future of rail mobility.
We design and manufacture to international standards and register our engineering in Mexico and the United States.
Quality management system based on AAR M-1003 requirements and AREMA technical criteria.
Our #8, #9, #10, #11, #15 and #20 geometries comply with the AREMA Manual for Railway Engineering 2024 and Portfolio of Trackwork Plans, the current standard for railway track in North America.
The only foundry in the region with explosive hardening of manganese steel.
Processes certified to international standards and Class 1 line interoperability. Every part is inspected against its own drawing before it leaves the plant.
Every part starts from an in-house drawing, registered as intellectual property in Mexico and the United States, and is delivered modeled in BIM.
Per AREMA standards.

New railway infrastructure in Mexico: from supplying the part to installing it in track.
AREMA (American Railway Engineering and Maintenance-of-Way Association) is the technical reference for railway track in North America. Our entire catalog is designed on its plans.
Hadfield manganese steel comes out of the foundry tough but relatively soft. A controlled shock wave hardens it in depth without touching the drawing geometry. We are the only company in Latin America with this capability, per ASTM A128.
We design and manufacture to international standards so every part is interoperable wherever it is installed.
We don't copy drawings. We make them. Every design is MACRO intellectual property and is delivered modeled to integrate into the customer's project.
100% Mexican manufacturers. Six steps under one roof: what is designed in the office is what gets cast, assembled and installed on track.
Casting, machining and assembly at our main plant in Nuevo León, with our own furnaces and overhead cranes.
Coverage area
The assembly is built and counted at the plant, loaded on a flatbed with our own equipment and arrives complete at the job site.
