I truthfully don't have a favorite type of passenger steam engine, but then again, Daylight engine 4449 is one of those engines that I'd be willing to run on my layout (set in Ohio) and NOT give a good reason why I have it on my layout, although it's an engine from my birth state (California).
i would have guessed streamlined 4-6-4 from your CNWman name.
The GS4s began their lives in Ohio...they were built by the Lima Locomotive Works and would have been moved, at least, over the NKP, the Erie, or the B&O.
