Chuffing tenders? I am not much of a steam fan but with the few real ones that I have been around, the chuffing seemed to come from somewhere further forward!
As far as US prototypes, it is especially odd as there were only two of them! It probably is the lead and has been offered in all of the normal scales: G, O, S, OO*, HO, TT, & N. Not shure about Z though.
*US OO
In the first photo, it is not derailed, it is on the diverging track.
In the second photo it was set that way to take advantage of the "free" spotlighting; the morning sun.
I liked the 0 scale GWR one enough to get a used one from Hatton's mostly though just to brag about it! BTW, I need to put a "&" between the G and the W as it really operates on the Greenville & Winnsboro Railroad! Now, my real preference for small locomotives is this one:
Baltimore & Ohio "Docksider"; they had two for use in street trackage in the port area of Baltimore.
EDIT: I will have to put the two (GWR & B&O) side-by-side one day for a comparison photo shoot.
Not by me, it is 531° R here right now. I have always liked it since I learned about it high school physics (or chemistry) as it gives the real temperature..
Shades of the Scullin Disc drivers. I love then and they are the only thing that makes certain large New York Central locos palatable!!

Raindrop changed considerably during the time after the operation; I suspect that, as the female hormones dissipated. I wish now that I had not had it done,
The version that I like uses"Disapearin'" and has great train photos:
I rode the "City" when I was stationed at NAS Memphis. On a Saturday, I rode from Memphis to someplace deep in Mississippi where I could wait (about an hour) for a northbound train to get me back to Memphis on Sunday.
The actual train in the video is privately owned and the video appear to be taken on different trips as the consist changes in several shots.
