Title:  Union Pacific Challenger pulling into Gladewater Texas fall 1990
Description:  Union Pacific Challenger pulling into Gladewater Texas fall 1990. Taken with my Bronica medium format camera. There weren't as many railfans chasing the beast back then as there was when the 844 came through. Did not get a lot of stills as I was shooting video back then.

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.
