 The folks of Louisville claim the experiences were based on the short Brook Street Line in 1915, which ran until 1930.For years, this route had been getting the cast-off equipment from the trunk lines until it became the joke of the town.Finally, the managing editor of the "Louisville Herald" asked the young Fox to draw some sketches caricaturing the antiquated vehicles, which is said to have cast the germ for the "Toonerville Trolley".
