PCC streetcar
By the 1960s most North American streetcar lines were closed, with only the exceptions noted above and discussed below remaining in service. During the same time all streetcar systems in Central America were scrapped as well. The survival of the lines that made it past the 1960s was aided by the introduction of the successful PCC streetcar (Presidents' Conference Committee car) in the 1940s and 1950s in all these cities except New Orleans.
