My gosh, what beautiful machines! My mind is now going back to the Ives factory, people on the line assembling the train I'll be getting. How it was run and enjoyed under Christmas trees, maybe a layout or just on a floor.
A child and dad (or both mom and dad) watching the train go round, having it make stops on it's route from New York to Chicago.
These are the trains, to me, that fire an imagination.
