1057 – Cincinnati, Ohio
This streetcar is painted to honor Cincinnati, which ran PCC streetcars from 1939 to 1951. Cincinnati was unique among North American streetcar systems in requiring two overhead wires for streetcars, one to supply electrical power, the other to provide a ground and complete the circuit. This arrangement grew from an early and (pardon the pun) groundless fear of electrocution from the standard streetcar practice of returning current through the tracks. (Trolley buses use two wires because they run on rubber tires, and have no metal tracks to use as ground.)
