Amtrak's eastbound Southwest Chief roars upgrade out of Seligman, Arizona; the signals of East Seligman are visible near the train's rear car. Note the headlight of another eastbound on the adjacent track just behind the Chief; from Seligman east the line was CTC signaled for bidirectional running and Santa Fe made the most of it. This view is from Arizona State Route 66, formerly part of U.S. Route 66.
