President Claudia Sheinbaum confirmed that the federal government is currently developing a new railway alignment near Salina Cruz, Oaxaca, to address operational risks following a fatal derailment on December 28, 2025. While officials aim to launch passenger service early next year, independent specialists estimate the necessary infrastructure upgrades could take at least 12 months to complete due to the technical complexity of the terrain.
Project Scope and Safety Concerns
The proposed project involves constructing a new 70-kilometer stretch of track designed to bypass a zone characterized by steep gradients and sharp curves. According to rail expert Carlos Barreda, this modification is essential for safely separating passenger and cargo traffic. The area remains a focal point for authorities following the December 2025 accident, which resulted in 14 deaths and over 100 injuries.
The planned infrastructure overhaul requires the acquisition of new rights-of-way and extensive coordination with local communities in Oaxaca to facilitate the construction of the alternative rail line.
Timeline for Passenger Service
President Sheinbaum stated that passenger operations will commence before the final track correction is fully realized. She emphasized that the service will adhere to technical recommendations provided by international specialists. Authorities are currently finalizing the executive project and securing the necessary land rights to move forward with the construction.
The decision to prioritize passenger service ahead of structural completion highlights a significant tension between the demand for transit connectivity and the engineering realities of high-risk mountainous terrain. The project’s success hinges on balancing international safety standards with the complex, time-consuming process of negotiating land use and construction rights with local stakeholders.
Operational Challenges
The modification process faces logistical hurdles beyond simple engineering. According to Carlos Barreda, the project requires complex new definitions for land use and construction rights across the 70-kilometer route. These territorial requirements mean that the project timeline remains subject to the pace of community negotiations and the technical demands of the specific Oaxacan landscape.
Frequently Asked Questions
What is the primary goal of the new railway alignment?
The goal is to build a new track to avoid a zone of steep slopes and sharp curves near Salina Cruz, which currently poses a high operational risk for both passenger and cargo trains.
When will the passenger train service begin operating?
President Sheinbaum expects the service to begin operating at the beginning of next year, even while the permanent track corrections are still underway.
Why do experts believe the project could take more than a year?
Specialist Carlos Barreda points to the technical complexity of the 70-kilometer stretch and the need to navigate land acquisition, construction rights, and community agreements as factors that could extend the timeline by at least a year.
How do you believe the government should balance the need for rapid transit deployment with the time required for comprehensive infrastructure safety improvements?
