Background

In the early 1980s, the Pittsburgh Port Authority began its "Stage I" project to completely rebuild portions of its streetcar system into their new T system

 lines earmarked in the "Stage II" plan, to be rebuilt at a later date as funding became available. Until that time, the "Stage II" lines would not be able to accommodate the new, heavier, and wider rail cars due to their age and condition, so the Authority needed to continue to operate their aging PCC fleet.

The solution was a fleet of completely rebuilt PCC's that could complement the new LRVs by operating on portions of the system that could not yet accommodate the larger, heavier cars, as well as having new components that extended their service lives until such time that their lines could be rebuilt and replacements bought.

Originally, the Authority planned to overhaul forty-five of their 1700 series PCC's. However, budgetary constraints and technical difficulties resulted in only sixteen cars being rebuilt. What cars that received the overhaul were essentially completely new vehicles built within the old car's body. All new propulsion and braking systems had been installed, as well as new interiors with improved lighting. They were each given two pantographs

 from the overhead wires. As planned, nearly all cars would be air-conditioned, but with the aforementioned budget issues, only one car, number 4006, was fitted with an air-conditioning system.

Service

The 4000 series was intended as an intermin solution for the Authority's unrebuilt lines, which could not accommodate the newer, heavier railcars. As such, they were assigned to the 47D Drake via Overbrook

, 47L Library via Overbrook, and 47S South Hills Village via Overbrook lines, as well as the 47 Shannon line, all trans-versing the Overbrook corridor. Later, it was discovered that the Library line could accommodate the larger LRV's with minor modifications, and the route was modified and redesignated as the "42L Library via Beechview"(as the Overbrook line could not accommodate the LRV's) and the PCC's were relegated to just the 47D,S, and 47 lines.

Unlike the LRV's which had both high and low level doors, the PCC's had only low level doors and were limited to street level boarding. As a result, all major stations on portions of the system that were shared by PCC's and LRV's(these being South Hills Village

 due to the deteriorated conditions of the track, bridges, walls, and other infrastructure. With that, routes 47 and 47S were suspended, and the 47D was reduced to a short shuttle between Drake and Castle Shannon, where riders would be required to transfer to route 42S or a bus to continue to downtown.

In 1999, the Drake shuttle was shut down, and the remaining PCC's were retired.
