The mayors of both Nogales, Sonora and Nogales, Arizona — known collectively as Ambos Nogales — signed an agreement to promote the moving of a binational rail line.

Sonoran Gov. Alfonso Durazo has regularly talked about his desire to move the rail line, which splits the two cities in half, out of their respective downtowns. Residents on both sides of the border have long complained about the dangers and delays brought by the line.

Last week, Mayor Juan Francisco Gim of Sonora and his Arizona counterpart Mayor Arturo Garino signed an agreement to work together toward creating the necessary conditions for the major infrastructure project.

One wrinkle is Union Pacific, which owns the line on the Arizona side. In February, a company representative told KJZZ News that the company has “no plans on its own to move the track.”

That same representative confirmed late last week that UP’s position had not changed.
