This looks to me like something a model railroader would build out of spare parts, but it's actually a Cincinnati Car Co. demonstrator locomotive, completed on Dec. 17, 1925. The non-equalized six-wheel trucks are strange enough, but check out that misshapen cab. It ran in demo service on the Western Ohio, the Cincinnati & Georgetown, and on the CH&D (C&LE) as their number 605. It was finally scrapped at Moraine, sadly enough.
The Scioto Valley was a third-rail interurban (the only one in the Indiana-Ohio network) best known for its big wooden cars, but it also had some more modern steel cars. This is #120, in its final resting place at 119 E. Main in Lancaster.
This is another Scioto Valley car, probably the same series, but its actual number and location are unknown.
And this is Western Ohio car #51, a Kuhlman. Again, the location is unknown, but it appears to be right next to a former main line.
