No fewer than thirteen people killed and ninety-eight wounded in rail accident in the nation of Mexico.

A tragic train derailment in the southern state of Oaxaca has claimed the lives of at least 13 people, an incident likely to revive censure from critics regarding the pace and handling of the country's flagship public works projects.

The accident occurred on the trans-isthmus railway, a line built to link the Atlantic and Pacific across the slenderest section of the Isthmus of Tehuantepec. This project was created to offer an different freight railway path to the Panama Canal, aimed at driving commercial progress in the area.

“We will rigorously clarify what caused this incident,” affirmed the country's president.

The official announced that, of the around 250 individuals on board, another 98 were injured, with five of those in critical condition. The leader added plans to travel to Oaxaca to confer with those impacted.

Key Undertaking of Previous Administration

The Interoceanic Train was a central development scheme of the former leader, whose presidency concluded the previous year. This venture was a hallmark of his administration's economic agenda for the southeastern region.

Another multi-billion dollar train initiative from that period, a tourist and cargo loop around the Yucatán Peninsula, was also part of the wider plan to revitalize the economy of a comparatively less developed part of the country.

Building Management and Risks Apprehensions

The building of both rail lines was managed by the nation's military, marking a dramatic expansion of its responsibilities in civilian infrastructure. They were executed at an rapid speed, beating forecasts to be partially opened before the end of that presidency.

However, this accelerated timeline had concurrently raised persistent apprehensions over operational security.

• Sunday's accident was the third such incident on the Interoceanic Train in the current year.
• This encompasses an previous collision this month when a train struck a truck at a railroad crossing.
• The other major rail project has also seen a couple of non-lethal derailments.

Calls for Review and Suspension

In the aftermath of the tragedy, the head of a primary political opposition urged an prompt halt in the development and management of all similar projects.

This stoppage was suggested while awaiting a full independent investigation. The party emphasized that the situation "calls for prompt explanations."

In reply, the president insisted that the train had been running in full accordance with all safety requirements. Promises were given that the government would remain "diligent" in both the construction and operation of these national undertakings.
