This train, the Union Pacific MRORV, was the second of three bunched up westbound trains I saw this day on Silver Zone Pass. It was behind the BNSF QPVS8J and ahead of a loaded coal train destined for export at Stockton, CA. Getting out here to Arnolds Loop requires some rough road driving and also a hike up a steep, rocky slope to get to the upper level trackage. Once you’re up here the view is worth the effort.
