ATTRAPI Rejects All Bids for Four Rail Stations Contract

ATTRAPI voided the tender to design and build four stations for the Saltillo–Nuevo Laredo passenger rail project after finding no bid met the full technical and financial requirements. The ruling cites issues such as overlapping key personnel, missing audited financial/tax documents, and failure to incorporate official amendments on Compras MX. Separately, ATTRAPI has launched a new tender for an 18.06km Monterrey-area segment with a 2026 budget of MX$1.70 billion (US$98.95 million).

Mexico’s Agency for Trains and Integrated Public Transport (ATTRAPI) has voided the tender to design and build four railway stations for the Saltillo-Nuevo Laredo passenger rail project, after determining that no bid met the full set of technical and financial requirements established in the procurement documents.

The decision is set out in the official Award Decision Minutes for International Open Public Tender No. LO-09-D00-009D00999-I-74-2025, issued in Mexico City at 5:00 p.m. on Feb. 25, 2026.

The procedure sought the design and construction of four stations, Derramadero, Saltillo, Ramos Arizpe, and Garcia, tied to the Saltillo-Nuevo Laredo corridor.

ATTRAPI notes that the tender was originally launched by the former Federal Railway Agency (ARTF) and later continued by ATTRAPI under the transitional provisions of the decree that created the new agency, published in the Official Gazette of the Federation (DOF) on Jan. 13, 2026.

In the ruling, ATTRAPI states it did not have any technically compliant proposals, because the bids received failed to comply with requirements set out in the tender rules. The agency therefore declared the tender void, arguing that no proposal complied with all technical and economic requirements, meaning the contracting authority could not ensure the works would be delivered properly and on time.

ATTRAPI says that the evaluation model is based on points and percentages, covering legal-administrative compliance, technical requirements, and economic requirements, using documentation submitted via Compras MX.

The ruling also references a minimum technical threshold of 37.50 points and lists multiple proposals that were rejected during the technical review. The document includes a section detailing consortia whose bids were rejected, with cited reasons including staffing conflicts, missing financial documents, and failure to reflect official clarifications or amendments published during the process. The reasons include:

• Group I (Comsa / VISE / COMSA / Regiomontana): Rejected because the same proposed key professional staff had been submitted in another tender (LO-09-D00-009D00999-I-55-2025, for stations on the Queretaro–Irapuato line) that had already been awarded. Under the tender’s rules, once one procedure is awarded, the same staff/equipment cannot be simultaneously committed in a way that conflicts with the awarded contract.

• Group II (Obrascón Huarte Lain / Caabsa / Constructora de Proyectos Viales de México): Rejected for omitting required tax filings and audited financial statements for the last three fiscal years (2022, 2023, and 2024) requested under the technical proposal requirements.

• Groups III, IV, V and VI: Rejected on grounds that include not incorporating an official modification/amendment published by the contracting authority on Jan. 6, 2026 in the tender file on Compras MX, and in at least one case, missing required legal documentation.

The ruling documents only the formal decision to declare the tender void due to noncompliance; it does not establish a new schedule or confirm whether ATTRAPI will reissue the tender under revised terms.

New Procurement, Monterrey-area Segment Moves to Tender

Separately, ATTRAPI has launched a tender for a new segment: the 15 A2 of the Saltillo-Nuevo Laredo project in Monterrey, described as a 18.06km section that crosses urban areas, rural zones, and industrial land.

ATTRAPI states the date of May 1 and an execution period of 1,007 calendar days, with a 2026 budget allocation of MX$1.701 billion (US$98.947 million) for that segment.

Meanwhile, the Proyectos México project sheet identifies the Saltillo-Nuevo Laredo train as a 396.3km passenger rail project within the broader passenger-service macroproject, with stages and procurement processes underway for different segments and components.

Back in December, Mexico’s Regulatory Agency for Railway Transport (ARTF) formally awarded ICA Constructora the contract to build and design 30.75km of the Saltillo–Nuevo Laredo passenger rail project in the Monterrey Metropolitan Area, under Segment 15 “B,” MBN reports.
