No fewer than 13 passengers killed and 98 hurt in train derailment in the nation of Mexico.

A fatal railway accident in the Mexican state of Oaxaca has caused the fatalities of at least 13 people, an incident expected to reignite critical opposition regarding the pace and handling of the country's key public works projects.

The accident occurred on the trans-isthmus railway, a route built to join the Atlantic and Pacific Ocean across the thinnest stretch of the Isthmus of Tehuantepec. This endeavor was designed to provide an alternative rail cargo route to the Panama Canal, aimed at driving economic development in the area.

“We will thoroughly investigate the reasons behind this tragedy,” declared the head of state.

The official reported that, of the some 250 passengers on board, another 98 were hurt, with five of those in serious condition. The president stated plans to travel to Oaxaca to meet those affected.

Flagship Project of Previous Administration

The Interoceanic Train was a signature infrastructure project of the former leader, whose time in office ended the prior year. This project was intimately linked to his administration's developmental goals for the southern region.

Another ambitious rail project from that era, a tourist and cargo loop around the Yucatán Peninsula, was also integral to the comprehensive effort to kickstart the economic fortunes of a comparatively less developed part of the country.

Construction Oversight and Risks Apprehensions

The construction of both train projects was managed by the army, marking a significant increase of its role in public works. They were completed at an fast-tracked rate, beating expectations to be partially inaugurated before the end of that administration.

However, this rushed timetable had simultaneously raised persistent apprehensions over operational security.

• Sunday's accident was the third occurrence on the Interoceanic Train within the past twelve months.
• This includes an previous collision this month when a train struck a truck at a level crossing.
• The other major rail project has also seen a couple of non-fatal derailments.

Calls for Audit and Pause

In the aftermath of the tragedy, the chief of a major opposition party called for an prompt halt in the building and running of all similar projects.

This halt was requested until the completion of a comprehensive technical review. The party stated that the loss of life "calls for immediate answers."

In reaction, the president maintained that the train had been running in total accordance with all safety requirements. Promises were given that the government would be "responsible" in both the construction and operation of these vital undertakings.
