I can't thank you enough for this stunningly beautiful twilight memory of a Santa Fe Railway westbound double-stack container train. I know this ethereal location well. The view, looking due west, shows the train in silhouette, as it glides across Bridge #1 of Abo Canyon, spanning the Abo Arroyo of the Manzano Mountains - in central New Mexico.
