I was sorting through a stack of discontinued books and out of date magazines in a train store, and found a book on a Rock Island engine facility that developed some interesting gas electrics, including some short ones that had long lives on the railroad. I now have other projects to contemplate for power chasses.
Made me wonder if there was a book on Rock Island cabooses out there as there is for the CB&Q (which I also am looking for). Seems like these prairie
roads with branches, MoPac, Q, and maybe the Rock, had interesting cabooses as did assorted southern short lines.
