No fewer than 13 passengers lose their lives and ninety-eight injured in train crash in the nation of Mexico.

A fatal train derailment in the Mexican state of Oaxaca has claimed the lives of at least 13 people, an incident likely to revive critical opposition regarding the rapidity and execution of the country's major government projects.

The disaster happened on the Interoceanic Train, a route constructed to join the Atlantic Ocean and Pacific Ocean across the slenderest section of the Isthmus of Tehuantepec. This initiative was created to offer an competing rail corridor to the Panama Canal, intended to promote commercial progress in the area.

“We shall meticulously determine the reasons behind this incident,” affirmed the country's president.

The leader announced that, of the around 250 people on board, another 98 were injured, with five of those in serious condition. The leader added plans to travel to Oaxaca to confer with those involved.

Key Undertaking of Former Government

The Interoceanic Train was a central development scheme of the former leader, whose term ended the prior year. This venture was intimately linked to his administration's developmental agenda for the southeastern region.

Another massive railway undertaking from that period, a passenger and freight circuit around the Yucatán Peninsula, was also integral to the broader strategy to kickstart the economic fortunes of a historically poorer part of the country.

Construction Oversight and Worries

The construction of both railway systems was overseen by the army, marking a significant growth of its responsibilities in civilian projects. They were completed at an accelerated pace, defying forecasts to be partially launched before the end of that government.

However, this fast-paced schedule had concurrently raised significant concerns over safety standards.

• Sunday's crash was the third event on the Interoceanic Train this year.
• This includes an previous crash this month when a train struck a truck at a railroad crossing.
• The other major rail project has also experienced several non-deadly derailments.

Appeals for Investigation and Halt

In the aftermath of the catastrophe, the chief of a major opposition party called for an immediate suspension in the building and running of all such projects.

This pause was suggested pending a comprehensive technical review. The party emphasized that the tragedy "requires swift accountability."

In reply, the national leader insisted that the train had been running in full accordance with all operational standards. Assurances were given that the government would continue to be "accountable" in both the construction and running of these national projects.
