was followed back into service by 1056. Second batch The cars that are presently numbered 1070–1080 were purchased originally by Twin Cities Rapid Transit in 1946. They were sold to Newark in 1953 and ran on the Newark City Subway until replacement by modern light rail vehicles in 2001. The San Francisco Municipal Railway acquired these cars in 2004 and had the cars overhauled at Brookville Equipment Corporation. Some of the cars were put in service in early 2007, but were taken out of service for wiring problems. These problems were eventually repaired. All these cars are single-end cars. Third batch A third group of PCC cars originally built for Muni in 1948 and 1952 were restored at Brookville in 2010–2011 and subsequently returned to service. This batch includes four double-ended "Big Ten" cars (1006, 1008, 1009, 1011) and the sole restored "Baby Ten" (1040), the last PCC car ever built in North America. Remaining PCC cars The remainder of the PCC streetcars assigned numbers 10xx which have yet to be restored mostly were acquired by Muni before 1952. This includes cars from three distinct sub-classes: the double-ended "Big Ten" (1014; the "Big 10s" comprise 1006–1015), the single-ended "Baby Tens" (1016–1040), and the "1050s". Of the 1050s, which were acquired from SEPTA in the early 1990s, most were restored and are in service, but two were scrapped: 1054 (ex-SEPTA 2121), which was damaged beyond repair in 2003 after re-entering revenue service, and 1064 (ex-SEPTA 2133), which was never rehabilitated after acquisition. Gunnar Henrioulle acquired several retired "Baby Ten" and "11xx" class cars as the largest single purchaser of retired Muni cars in the mid-1990s. He also acquired an ex-San Diego PCC (#502), two ex-Toronto PCCs (#4404 and #4472), and built a double-ended PCC from ex-Baby Ten #1024 and #1035. Henrioulle had intended to use the PCCs for a heritage streetcar line called Tahoe Valley Lines, but the government of South Lake Tahoe, California did not approve his plans and he was forced to sell off most of his fleet in 2001; four of his Baby Tens (#1026, 1027, 1038, and 1034) were reacquired by Muni at this time. 11xx class The 1100s series of cars were purchased in 1957 by Muni from St. Louis Public Service. These cars were retired in 1982 with the inauguration of Muni Metro LRV/subway service, with most being sold off to Henrioulle for Tahoe Valley
