Grupo México is preparing a bid for Argentina's freight rail operations in partnership with Wabtec, Mexico Business News has reported.

The pairing would bring together one of Latin America's largest industrial transport groups and a major US-based locomotive and equipment supplier. Under the reported arrangement, the two companies intend to submit a joint offer for Argentina's state-run freight railway.

Grupo México operates extensive rail freight concessions in Mexico through its transport division, and its interest in Argentina signals potential expansion beyond its home market. Wabtec, which supplies locomotives, freight cars and signalling equipment to operators worldwide, would bring manufacturing and fleet technology capability to the proposed bid.

Details of the offer remain unconfirmed. The initial report does not specify the value of the contemplated bid, the scope of assets covered, or a timetable for submitting the proposal. Neither Grupo México nor Wabtec has publicly disclosed terms, and Argentine authorities have not confirmed whether a formal tender process is under way for the freight network.

Argentina's freight rail sector has long faced questions over investment levels, fleet condition and the balance between rail and road haulage for bulk cargo. Any transfer of operating control to a private consortium would hinge on regulatory approvals and on the structure the Argentine government chooses for the transaction.

For Grupo México, a successful bid would extend a freight franchise portfolio built largely around Mexican mining and industrial traffic. For Wabtec, participation as a bidding partner rather than purely as an equipment vendor would tie its fortunes directly to the outcome of any future concession and the fleet renewal that would likely follow.

Confirmation of the bid's scope, valuation and timeline is expected as the companies finalise their proposal and engage with Argentine officials.
