PCCカー
In December 2005, the San Diego Vintage Trolley Co. purchased three former San Francisco Municipal Railway PCC cars (one numbered 529). Car No. 529 was later fully restored for public rail service. Three other PCC cars, two from SEPTA and one from New Jersey (531-533), were subsequently purchased. In March 2014, MTS took possession of a second 1946 PCC streetcar, destined to join public service as Car #530. It was estimated that the mostly cosmetic restoration work required to restore Car #530 to service would take six to eight months. The PCC cars were planned to run on a loop route around Downtown using existing San Diego Trolley tracks. San Diego Metropolitan Transit System, in a partnership with the San Diego historic streetcar society, began select weekday, weekend and holiday mid-day service in August 2011 on this new heritage streetcar Silver Line, which operates around Downtown San Diego using the renovated PCC streetcar #529. By March 2011 MTS began work on a study to evaluate the feasibility of reconnecting Balboa Park, the San Diego Zoo, and Downtown San Diego through a fixed-guideway, electrified streetcar line&lt;ref name="MTS City/Park Streetcar Feasibility Study"&gt;&lt;/ref&gt; that might operate as an extension of the Silver Line and might be operated with other restored heritage streetcars.
