Across Arizona: BNSF’s Arizona Mainline Enjoy a fantastic adventure across the Grand Canyon State on BNSF’s Seligman and Gallup Subdivisions. You’ll travel the double-track main line from Needles, CA., east across the Mojave Desert to Kingman Canyon. The steady drumming of the colorful GE diesels fills the air as the grade reaches 1.8%, and the scenery changes dramatically as the railroad gains over 6,000 feet in elevation. Head through Crozier Canyon and the double-track tunnel at Nelson and up the western slope of the Colorado Plateau to Williams. Excellent videography makes for a very entertaining show. 1 hr. 48 min.
