UP 4342 rolls south on the Spine Line towards Mason City, running parallel to the now out-of-service IC&E tracks (ex-Milwaukee Road I&M Sub).

With an older SD70M on the point, an eastbound UP auto train rounds the big curve west of Beaumont at Nicklin, and will soon be rolling downgrade into the low desert toward Palm Springs and Yuma.

Deep in the heart of San Timoteo Canyon, an eastbound UP auto train works through some curves near El Casco on the former SP Sunset Route.

UP 4342 leads this eastbound auto train as it rounds the big curve at Beaumont.

Something told me to wait for 33K today. I did...and as the sun was setting I was rewarded with a pair of UP units which had, earlier in the day, been part of the consist of NS 212.

Southbound with a UP flying eagle on nose. Train is approaching mp 260 below town.
