I originally posted information about Antique Powerland on my website in a PLACES page on November 23, 2007 and last updated it on December 18, 2009. I am posting the railroad-related information here, with pictures and information from the 2010 Great Oregon Steam-Up. All of my information about Antique Powerland can be found at PlacesPages.
Streetcars #1118 and #1159 are Presidential Conference Committee (PCC) Cars built by the St. Louis Car Company in 1946. PCC cars were a standardized modern streetcar designed by the Electric Railway Presidents Conference Committee from 1929 to 1934. The first PCC cars were built in 1936, and by the time the last were built in 1952, over 5000 had been produced for use in the United States and Canada.
These two cars were originally built for the St. Louis Public Service railroad, where they were numbered #1720 and #1727. The San Francisco Municipal Railway (MUNI) leased these two cars in 1957, and purchased them outright in 1961, assigning them their current numbers. They were retired in the 1980s when new subway lines replaced five streetcar lines. The PCCs were not compatible with the high platforms of the subway line, and they were replaced by new light rail vehicles.
