 The four remaining PCC cars were retired in 1999.These PCCs were from an original fleet of 12 "homebuilt" cars constructed in the 1980s in the Port Authority shops using a combination of new underframes, lower body panels, front and rear ends, interiors, wiring and controls, together with reconditioned components such as trucks, motors, and upper body parts and windows reused from original Pittsburgh PCCs numbered in the 1700 series.They avoided the breakers yard, along with some other trolleys from the later years of PAT ownership.
