From the "They're really going to do this?" department:
The 10th & 11th of May, there will be a celebration on Ogden, UT for the 150th anniversary of the transcontinental railroad. This was the high technology of it's day - a six day trip by land across the country, rather than weeks by stagecoach or months by ship.
So, I'm not a photographer by any means, but I would like to watch 1.2 million pounds of 1940's technology run again, simply for grins and giggles. I'm reading elsewhere that there will be thousands of people, all wanting to watch a bit of history be reborn. If you've not seen news stories, I'm certain they will be coming up soon.
The last of these specific locomotives were operational in the late 1950's, so there will be only a few that were alive at the time these were retired for diesel-electric locomotive power. Union Pacific has had a heritage fleet for several years. During the centennial celebrations of Arizona statehood, another locomotive (UP 844) came thru the area - photo below:
My wife was grabbing the shots, while I piloted the motorcycle.
The locomotive we'll be looking at in May is nearly twice the size of the one in the photo!
I can only be away from home for a couple of days to watch this; room reservations are made, and hopeful that the weather in southern Wyoming is spring-like in early May.
