If that's a carbon foot print, I say "Bring it on and lay it on
thick!" 
Wow! I like to think that some guys weather and rust up their engines way too much, but it's hard to argue with them.

This old timer must have been weeks away from the cutting torch to be allowed to deteriorate to such an extent.

Either she was smoking it up for a photo runby or she really was on her last legs. The UP was famous for running with clean stacks and maintaining their steam engines well, so this example is pretty unusual.
If you can find a copy of "High Iron to North Platte", I would recommend you get it. It deals with the UP's operations in Nebraska during the steam to diesel transition era. It has some great photos of steamers and early diesels. It's out of print now, but an excellent book.
I like those old Big Boys. Too bad nobody has gotten one back in service, but somehow I don't the EPA would like that much. There were some experiments done to get a Big Boy to run on oil but it never worked out. If I remember they couldn't get it up to even one third power. It would be nice to see one running again.
The Big Boys probably could have run on oil if they had more than one burner under the firebox. The Challengers had four burners, with a much smaller firebox area. By the time the UP tried to convert them to oil in 1945, diesels were already the wave of the future, so I suspect the UP was content not to spend any more money on them, and let them finish their lives running on low quality Wyoming coal.
nice just added it to my wallpaper also& sent to others-too late for copyrights -oops!
Wow, he had to be choking the engine to make that much smoke!
Hamming it up for the photographer no doubt, been there done that.
Maybe they were just smoking it up before passing Al Gore's mansion. Or in other words teh UP's middle finger to carbon credits

Carbon footprint? Al Gore can go jump in a lake (as we sit here shivering during the coldest winter in decades)

Long Live Steam!
You're forgetting that most of the "facts" Mr. Gore presented have since been proven to be inaccurate or simply made up.
just added it to my wallpaper...
