This is an engine that id hope would be made in O scale other than my KTM and suprised it hasn’t by anyone else. I bought an HO Brodway Limited A while back because I loved the engine so much. (I don’t have HO) 

Out of the 144 of them that were built some may know Union Pacific #5511 “TTT-6” is the last remaining survivor of that class. The engine was also in “Last Of the Giants” Film. 

The coolest part of the engine besides the huge overhanging flat faced boiler is that some were built with “Young” Valve gear which is quite rare. Others were built with “Walschaert” Valve. Seeing the movement of The Young Valve gear is dramatic compared to the Walschaert. Also some featured a large exhaust stack others had a smaller one. Baldwin, Lima, and Alco built them for UP and followed the same cosmetic design.

Lets have Scott add that to the list of produced 3rd Rail Engines!

The engines pictured in the first and fifth photos are, in fact, 4-10-2 (FTT) -- there's another wheel on the front pilot lurking just at the trailing edge of the steam piston.  Here's the loco database information on each:

http://www.steamlocomotive.com...mp;railroad=up#13994

You'll see both the 8804 and the 5098 included in the number lists.

It turns out that the 8804 was one of a class of 10 FTT locos that had three cylinders - if you squint hard you can see the front edge of the center cylinder just over the lead wheel of the pilot on the 8804.  Interesting, as I thought the famous UP 4-12-2's were the only three cylinder locos UP had (which I got to see, hear and feel as a kid in NE)...

Here's the locobase link for the TTT's

As you noted, the last UP TTT is stored in Cheyenne -- there are eight other 2-10-2 locos, including two that are operational (Iowa Interstate's two chinese built locos) - here:

I do see that lurking wheel. I did this from my phone, I need to open my eyes a bit more. I will remove the pictures

Hot Water - I'm probably missing your point, I think.  According to the link I posted above - and again here: http://www.steamlocomotive.com...USA&wheel=2-10-2  there was a ton (bad pun intended) of Santa Fe-type locos (aka 2-10-2) built - 2179 owned by 44 different railroads.  So to the extent that having an engine in your favorite RR livery helps drive sales (a topic for which I claim no expertise) then you'd think offering a TTT loco wouldn't be out of the question.  By contrast, for the widely modeled 4-8-4 locos only 1126 (slightly more than a half a ton...) were built and owned by 36 railroads.

Since the original post was specifically referring to a Union Pacific TTT Class, just because many, MANY other railroads had the same wheel arrangement locomotives, i.e. the 2-10-2, doesn't mean that ANY of them even remotely LOOKED like the UP 2-10-2.
