I came across this article in Subchat by chance. I never knew that Louisville had an early elevated line. It was not just a structure for steam trains to pass through a city but a regular line with a schedule. First run with stream trains, it was later converted to overhead trolley. Several cars ran together. The tall pole in some of the drawings below are early arc lights that lighted the waterfront. What an interesting article. Louisville may have had also a trolleybus system that was unique, it passed between two states. I may have read something about this years ago in an article published in the North American Trackless Trolley Association. I read the article very fast, and I think the system folded in 1907? Sorry for the truncation. See link in Subchat.
