The abandoned railroad route between Polvo and Vail was once operated in Arizona by the Southern Pacific Railroad.

That was the old line that went from Vail to Tucson across what would become DMAFB. The line was removed & a new line built alongside the El Paso & Southwestern out of Vail and West to Tucson.
