4-6-6-4 Union Pacific Challenger prepares to leave Kansas City Union Station!

Built specifically to take on long grades like her cousins the “Big Boys” 4-8-8-4’s, the #3985 Challenger was designed to pull freight fast up long grades without helper engines.

Currently, UP’s #3985 Challenger 4-6-6-4 is undergoing renovation as Union Pacific’s steam shop in Cheyenne, Wyoming.

Since the #3985 was so long, she was built as an articulated locomotive that allows the 4 wheel front truck to go with the bend in tracks which would have otherwise be troublesome to such a long boiler. Hence, she can articulate herself around the curves because the front of the boiler sits on top of this truck much the same way a big rig diesel truck hooks up to its’ trailer.
