The Golden Spike Tower and Visitors Center is home to an attraction for visitors to view the Union Pacific Bailey Yards, the world’s largest classification yard according to the Guinness Book of World Records.

The tower is a replacement for a 14’-0” high viewing platform, originally down the road from the new site.

The building is a combination of 2 types of structures. The lower building is the entrance and visitors center which is wood frame construction with brick veneer built to resemble and up to date look of an old depot. This portion also houses the great hall, gift shop, restrooms, offices and entrance to the tower.

The tower pushes the visitor into the future with pre-cast panel construction for the 8 story viewing platforms. The open air 7th floor platform at 82’ high allows visitors to take in all the noise and unobstructed views of the yard itself.

The enclosed, climate controlled 8th floor at 95’ allows visitors to take in a 360 degree view of not only the rail yard but the entire Platte Valley

The tower size and shape, in plan is a 48’ x 23’ stretched octagon shape constructed of white pre-cast panels topping out 8 stories above the ground.

The foundation is comprised of 63 – 18”x 25’ deep auger cast piles capped with a 4’ deep pile cap extending 3’-4” outside the pre-cast panels.
