Re: UP 844 in Magnolia

I can't prove it but I think that when limiting the discussion to the 4-8-4 "Northern Class" locomotives -- the Santa Fe 2900 series were the largest. Certainly they had much larger tenders than the UP versions.

For example, the Northern Pacific Z5 Yellowstone 2-8-8-4 had more tractive effort than the UP Big Boys but was a few feet shorter. It's firebox was so massive, bigger than the Big Boy's firebox that before the first Z5 was commissioned they had a dinner party for 16 notables in the fire box!. (Great idea for a restraunt in Austin? Have a hot time at Austin's newest restraunt, The Firebox!)

But, one thing we know for sure about UP 844 is that it is the one and only major class 1 locomotive in the US to be in continuous service since it was placed on the roster when built. As many of you know, it's number was briefly changed to 8444 when the 800 class diesels came to the UP. But, 844 outlasted them and got it's number back!!
