For some reason, a number of roads--Erie (other than USRA), New Haven, Great Northern, Northern Pacific, the two big Canadian lines--have been underrepresented in the new model roll-outs we've been seeing in recent years. Among these is the Chicago, Rock Island & Pacific, the famous Rock Island line.
Now, I don't know if there are enough modelers of the Rock Island to justify someone producing models of CRI&P steam prototypes, but just in case there is, here is a collection of photos and data on a variety of Rock Island engines; alternately, this collection of images may reveal models that can be kitbashed from other engines that are currently offered.
Some of these photo links have been posted recently in a 4-6-2 proposal thread, but they are included here in the interest of having all the Rock Island material I could locate in one place.
First, a listing of Rock Island locomotive classes with some specifications; sadly there are no numbers nor some other material that would normally be in a proper roster. Still, it is a starting point.

Rock Island steam info is not too common on the internet. We'll start with some information and photos on the three surviving Rock Island 4-6-2s:

Some random images from Bob Yarger, a former editor at Railway Preservation News; of note to me are some of the Atlantics, including some with the main rod connected to the first driving axle, like a 4-4-0. The Santa Fe had some engines like this; the layout suggests these engines, like Santa Fe's, may have been built as compounds back close to 1900:

Erecting drawing of a 4-4-2, apparently called a "Chautauqua" type on the Rock Island:

To my eyes, this one looks to be based on a USRA heavy 2-8-2:

This one reminds me of a New York Central engine, perhaps an H-7:

Quite a bit of rebuilding visible on this one:

That will have to do for now; Have Fun!

From the above; looks like a USRA 0-8-0 to me (Life Like); possibly a copy; note slope-front cab, not quite USRA design, could have been a modification of a USRA original, or a preference by CRI&P when ordering a copy:
