Found a used one for a good deal, and it is actually quite close to scale based upon my own research (found a railroad museum with measurements of their real one), or at least close enough for me. I do see I might add/change some details eventually but I am pleased with it so far. For outdoors use (my eventual goal) this will be great.
I gotta say I am impressed compared to the stuff I have been messing around with (G scale/older O gauge). This one has PS2. I can probably do without the announcements, I only really *need* the bell, whistle, and chuffing but the startup and shutdown is nice. I do wish the volume would go down one more notch before shutting off completely.
Boy does it put out the smoke! My wife promptly forbid "smoke on" in the house before I even got it into the house - I was just testing on a test track in the garage. 
Are there 2 rail wheelsets/trucks for these?
