I caught sight of this loco years ago in "Steam Locomotive Cyclopedia-Vo1 Model Railroad." What a Beast, there was an image of the loco negotiating a switch with crew members watch each drive wheel making sure it did not crawl up on to the rail.
The Beast! The UP 9000 series .

Ron,

After building the Union Pacific 9000 series with six coupled axles (4-12-2), the next step was to separate the six axles into two sets of three, resulting in the articulated Challenger locomotive (4-6-6-4), to track better on curves.
