On my way to pick up the railbender from Cale in Spartanburg I spotted a very unusual site.
A Union Pacific SD 90, as well as a UP SD 70 on the Norfolk Southern line. They were stopped on
the Clinchfield bridge. As I turned around in traffic a NS northbound obscured the view of the UP locos. I parked to get a photo, the NS cleared, and the UP SD’s were gone

From what someone told me, UP was getting rid of a bunch of loco’s. I saw a few on the Florida East Coast line last summer.
Ralph, I’ve seen them around here before-really weird at first glance!
Last summer I saw a Norfolk Southern loco in a UP consist out near Yuma.
