I am going to start this post by reminding everyone this is about TRAINS NOT politics, so please keep it that way.
Talk about trains and their effect on defining / altering History, well this is hard to beat as a single event!
Yes I have heard of the Golden Spike, but that was different, it was a defining moment. Used to illustrate how this Our Nation built Railroads, and how in turn Railroads built Our Nation.
Anyhow there was a post that got me "derailed".

I started thinking it would be interesting to know what motive power was used to pull the train over its 30K mile run. Why you ask, well IMO this time (Late 1948) may have been the pinnacle of the Transition Period, and You can bet every railroad wanted to put there "best foot forward". It also reveals what different RR management thought that might be.
So here are some links I uncovered. If anyone happens to have a definitive list already compiled, please feel free to share it!
