UP 3985 @ Rock Island Arsenal
Title:  UP 3985 @ Rock Island Arsenal
Description:  UP's big beast of the 90s, this unit has sat for around a decade prior to being moved from Cheyenne to Silvis. This is the first time I've seen any moving steam beyond IAIS's 6988, and seeing such a large locomotive this close was something that had me in awe.

UP3985's driver @ Rock Island Arsenal
Title:  UP3985's driver @ Rock Island Arsenal
Description:  69 inches of driving wheel is nothing to scoff at on a locomotive. Everything on this locomotive seemed massive, drivers included, even placed next to me, and I'm 6'1! Regardless, seeing all of the small details on this unit was pretty awesome, and I was glad to get this beast.
