What Era, Railroads, & Locomotives are you set on?

I think so, there may actually be two of them if i'm not mixing some things up. I was under the Impression that UP itself was working on another Big Boy. I have a DVD somewhere that was on the Challenger that UP maintains and operates, and while they were touring the restoration area, you could not only see a Big Boy back there, but i think the guy being interviewed mentioned they were working on it as well. I'm not sure of the age of footage of the DVD, and it may be the same one. I'll have to dig it up.
