Amtrak’s California Zephyr
Amtrak’s scheduled daylight operation of its California Zephyr over Donner, makes this popular train by far the most photographed train on the pass. In November 2003, Amtrak number 5, passes the signal bridge near Boca Dam on its westward ascent of Donner. I featured this photo in my book The World’s Most Spectacular Railway Journeys.
