Ferromex (reporting mark FXE) (syllabic abbreviation of Ferrocarril Mexicano, 'Mexican Railway') is a private rail consortium that operates the largest (by mileage) railway in Mexico with combined mileage (Ferromex + Ferrosur) of 12,100 kilometres (7,500 mi) and is often classed with North American Class I railroads.

Ferromex began operating on February 19, 1998, following the privatization of most of the government-owned railways by Mexican President Ernesto Zedillo Ponce de León.

Ferromex hosts the Ferrocarril Chihuahua al Pacífico "ChePe" railroad, a tourist line that runs through the Copper Canyon.

In November 2005, Grupo México, the majority owner of Ferromex, purchased Infraestructura y Transportes Ferroviarios, the parent company of Ferrosur, another of Mexico's Class I railroads, in a US$309 million stock transaction.

[4] Following the November 2005 purchase of Ferrosur by Grupo México, Kansas City Southern de México (KCSM), successor to TFM, petitioned the Mexican government to block the merger of Ferrosur and Ferromex.
