The "Tren Maya" is Mexico’s flagship railway project. The route network on the Yucatán Peninsula is expected to be around 1,500 kilometers long by the summer.
Certain sections of the route run through a jungle area that is considered the second most important forest reserve in Latin America after the Amazon. Environmental activists worry about ancient cave systems and freshwater supplies. In February 2023, the authority responsible for the “Maya Train” project admitted that 3.4 million trees had been felled.
