Wow, I feel like we just viewed a briefing at NSA headquarters! Great photos and highlights. The B-17s will start their bombing runs just after the P-51s strafe the ack ack emplacements.
I have been past Black River Falls several times. If I am not mistaken, there is a casino nearby, so the "display" doesn't suprise me. I also know there is a race track somewheres around there and I recall seeing a D4 7U and a 112 or 212 grader parked out back. All of this from the seat of a truck whizzing by on the interstate at speed. There is a lot of nifty looking iron out there if you turn your head 90 degrees to the left or right. (The problem is the exit ramp is never convenient.)
my guess would be Lunda Const or Hoffman Const both big contractors headquartered in BRF. don't know if they have websites or not.
Here is a link. A railroad buff took a picture while driving by.

Thanks for the link. I tried to view it from Google "Street view" and the closest view is from the main drag, and it is not even clear what is on the train other than grey and yellow blobs. They look like a class outfit.
