20th century In the 1980s,
SEPTA was in the process of upgrading its
subway–surface trolley lines, replacing its fleet of PCCs with new light rail cars. Some lines, such as Routes 6, 50, 53, and 60 were converted to buses, while Routes 15, 23, and 56 continued to use PCCs into the 1990s. In 1992, SEPTA ended streetcar service on these three lines as well. In response to public outcry over the conversion, SEPTA stated that the suspension of these lines' streetcar service was temporary, and that they would be restored in 1997. However, during this time little was done to restore the lines, and as 1997 approached, it became clear that SEPTA had no immediate plans to restore streetcar service to these lines. In September 1997, at a City Council hearing, Jack Leary, SEPTA's general manager at the time, announced plans to restore streetcar service to only one of the three lines, Route 15. The initial proposal was to purchase twelve
low-floor articulated light rail cars, to make some existing railcars available for the line. However, this was found to be prohibitively costly, and the decision was made instead to rehabilitate older cars for the service. SEPTA sent 18 of its retired PCC cars to the
Brookville Equipment Company to be rebuilt, with another six to be used for parts.
21st century The first of the rebuilt
PCC II cars debuted on September 9, 2003, , rebuilding of the PCC II fleet into
PCC III cars continues, with the first finished cars entering back into Route 15 service on June 16, 2024. The PCC III fleet is projected to be replaced by 130 new low-floor trolleys to be built by
Alstom. The new trolleys will be 80 feet in length and fully ADA-compliant, which the current PCC III fleet have been since their PCC II rebuild. The trolleys will be distributed among Route 15, the subway-surface trolley lines, and the
Media–Sharon Hill Line. The first trolley is expected to be delivered from Alstom in the Spring of 2027, with the last trolley to be delivered some time in 2030. However, SEPTA does not plan on reconstructing the G for its Trolley Modernization Program until 2041 at the earliest. ==Design==
