Travel to beautiful northern Arizona and one of the most interesting stretches of railroad in the United States, BNSF’s mainline over the Arizona Divide. Visit the line between Kingman and Flagstaff, with great western scenery and over 60 trains a day. You’ll see the split-level track in Kingman Canyon, rugged Crozier Canyon, the remote, beautiful Crookton Cutoff, and the beautiful alpine area between Williams and Flagstaff. This is one of the busiest railroad lines in the United States, the route of the old Santa Fe. Enjoy lots of contemporary diesel action running through great western scenery.
