This model has been a work in progress during the past few years. I have reached the maximum upload file size therefore shall consider this model complete.
Union Pacific "Big Boy" no. 4002, was the 3rd of 25 production units, measuring just over 123 ft long x just under 11 ft wide x 16 ft tall. Modeled from plans, images, and my general appreciation for this particular locomotive. There are few areas that were figured out to the best of my general understanding of how this articulated locomotive mechanically operates.
