Officials from Pima County, Arizona, the state, and Mexico are in talks to extend a planned passenger rail route from Nogales, on the Mexican side of the border, to Tucson, connecting the United States to Mexico's 700-mile rail system.

According to reporting by Connor Greenwall for KJZZ, "Discussions occurred at a Pima Association of Governments meeting on January 19 after local authorities were given a presentation by Álvaro Madrigal, director general of the Mexican railroad agency."

While there is no concrete proposal on the table, officials from all sides expressed interest in the project. "If they can do 700-plus miles of track, we've got to be able to figure out how to do 63 from the border up to the Tucson area," said Pima County Supervisor Matt Heinz.
