UP 3564

Hi guys, I've been looking for information on this unit as it is or was the last UP unit painted in the 1970s scheme, and I can't seem to find any info on it, what came of the unit? Is it retired? Still in service?

Couldn't find any recent photos, so here's a shot of it from 2007 sitting in the dead line at Hinkle, OR, at a time when UP began selling off a lot of its SD40-2's; especially those that weren't kept around for local/yard service. Last info I could find was that the unit had been moved to storage, don't know when or where, or if it's been moved again since...
