“It is a magnum opus, we are not exaggerating if we say that there is no one like it in the world today.” The phrase It was pronounced at the end of 2023 by former Mexican president Manuel López Obrador, and although in politics (no matter the nation) the use of superlatives is common, the truth is that it was not misguided. What López Obrador was referring to was the Mayan Trainan ambitious railway circuit of more than 1,500 kilometers that started more than two years ago between Campeche and Cancun and continues to take shape become a priority of the Government.
Mexico needs it to be a success, but not at any price.
What has happened? That the Mexican justice system has just reminded the country’s administration that, no matter how important and strategic it may be, the Mayan Train cannot advance with its back to the regulations. That is why it has issued a suspension order that will mark the works of one of its most controversial sections.
For the project to continue advancing, from now on the authorities will have to put more effort into protecting natural resources in one of the most sensitive areas through which the railway must circulate: the region located between Cancún and Tulum, right where it passes. Section 5 of the Mayan Train.


What has justice done? Dictate a final suspension order focused on that specific section. That does not mean that it has condemned the project or that the Mayan Train should give up its Cancún-Tulum stretch, although it does represent a wake-up call for those responsible for the project and a reminder that the work must advance while respecting its environment. Basically what the magistrate has done is demand that the environmental authorities of Mexico confirm that the project complies with the regulations and are responsible for monitoring it.
The court order obliges the Federal Environmental Protection Agency (Profepa) to carry out direct and permanent inspections in the Cancún-Tulum section. No revisions on paper or reports signed from the offices in Mexico City, miles from where the works are being carried out. The ruling was issued thanks to the mediation of the organization ‘Save me’ and is addressed to Profepa and the General Directorate of Crimes, Commutations, Complaints and Complaints.
Is it so important? Yes. According to precise The Chroniclerthe order places several duties on the competent agencies that, in practice, will force them to reinforce their surveillance. To begin with, they will have to carry out direct, field supervision of the project. They must also verify the effects on protected species, the protection of cenotes and control underground rivers.
Finally, the ruling points out the need to prepare detailed reports. If these demands are not met, those responsible could face sanctions.
What do environmentalists say? Sélvame has valued the judge’s decision as “a significant achievement” in the defense of the media. “It is an important step towards the protection of natural resources and guarantees that verification, inspection, conservation and protection actions will be carried out in the event of pertinent public complaints,” celebrate. The groups that have been warning for some time about alleged irregularities, such as tree felling or unsupervised work that affects wetlands, they advance that they will be attentive so that the order is carried out.


What area does it affect? That is one of the keys. The Mayan Train is a wide railway circuit, more than 1,500 kmbut the focus has been placed on a very specific point: Section 5, which is in turn divided into various segments (north and south) between Tulum and Cancun. In total, according to the Mayan Train Guidemeasures just over 100 km. Beyond its length, shorter than other sections, the local press stands out which is one of the most sensitive. The reason: the presence of vulnerable ecosystems, caves and underground rivers and the threat to their biodiversity.
In August 2024 the Verified platform assured that the construction of the Mayan Train had affected approximately 7.3 million trees, a good part (3.5 million) in Section 5. In 2024 A court has already ordered work to stop until geological, geophysical and hydrological studies are delivered.
Why is it important? To begin with and as López Obrador himself recognized in December 2023, when he presided over the inaugural tour of the Mayan Train, because the railway circuit is not just any project. And not only because of its impact on the environment, its dimensions, its costs or enormous ambition.
With it, the Mexican authorities aspire to promote the development of the southeastern region, articulating a new communications backbone that favors tourism. The problem is that its implementation is not being easy. Its premiere has not had the expected success (at least in passenger traffic) and its management has just change handsmoving to the Secretary of Defense.
