Below is a drawing of a PRR steam locomotive of the "super, multi-section articulated type". Although it was never built, the Pennsylvania Railroad did apply for a patent on it, circa 1944.
It's just one of the weirder things that can turn up in a Google Patent Search. Oddly enough, its outline is rather similar to the GG1...
Who knows? Maybe in one of the alternate universes, it was actually built, and perhaps is still in operation!
