“Both the big work horse moved millions of tons of freight and troops for the effort during WWII. Thank goodness we had them!!”

Indeed they did. It can be argued that the Challenger was the world’s largest passenger locomotive, although it was designed primarily for moving fast freight.

It's a shame that the only 2 remaining Allegheny's are static. We still have a Big Boy or 2 that are still road worthy and those that love the old workhorses are passing down the knowledge (to a few) as how to run them, service them, and rebuild them.

Couldn't agree more with your comment on the Challenger......dat sucker is fast on flat grade. IIRC, UP's #3985 was chased at 70 mph not to long ago.
