This is fascinating to watch. The locomotive appears to have 4 cylinders with 2 being inside of the side frames. The crankshaft for the inside cylinders is the main driver axle.

Thanks Bobby! I used to work (draftsman) in a machine shop back in the 70s and was always amazed at how they could take a drawing and make pieces that would fit together. I can't imagine the labor involved in making a giant, living, breathing steam locomotive.

Yes, she was a four cylinder, compound locomotive, i.e. the smaller high pressure cylinders are on the outside, while the low pressure cylinders are in-board.
