The tail end of a San Bernardino, CA to Alliance, TX intermodal leaves the great state of Arizona for New Mexico, it begins the one percent grade up the western slope of the Arizona Divide, across the Navajo Nation, and into Belen, NM; the next crew changing point. What makes this train unique is that the last 57 cars out of 90 are all Wal-Mart trailers. They trailers, produced by Hyundai, are made in Mexico and are being delivered to Texas where they'll be put into service.
