Spen:

Found it! There were a couple of engines like yours, yours and the Skookum that
boomed around on a couple of logging roads. Yes these were logging engines but I
won't snitch...

Skookum/#7 was 65 tons on the drivers so that's 130,000 lbs divided by four or
32,500 lbs per axle so you bet that works. The Russian Dec is about the same. By
comparison the USRA light Mike is about 50,000 pounds.

Also just clutching out of the air... A bridge survey I found lists a Wisconsin
"riveted pony truss" along with several wood pile and deck sections, implying a
light bridge, at a Cooper E-56 so I'm kinda in the ballpark with the USRA light
as an upper limit.
