The Saint Charles Street RR operated several lines which came together on the lower portion of St. Charles Street, from Canal to Lee Circle, then diverged into several uptown neighborhoods.  These included the Clio, Dryades, and Carondelet lines, but not the St. Charles line, which was built by the New Orleans & Carrollton RR.  (However, modern restrikes of these buttons are said to have been worn unofficially by operators on the St. Charles line.)  VanCourt catalog number 52/17.
