Pittsburgh Railway Company (PRC) was formed on January 1, 1902, when STC acquired operating rights over CTC and UTC.

[10] Highway improvements in the Duquesne-McKeesport area resulted in the replacement of trolley services with buses on September 21, 1958.

PRC was engaged in ongoing litigation over the failure of the Pennsylvania Public Utilities Commission to provide streetcar tracks on the new bridge.

In the end the company was allowed to abandon 27 miles (43 km) of street track in situ and was awarded $300,000 as compensation.

The Charleroi interurban line was cut back to the Allegheny County border at Library (Simmons loop) in June 1953[12] It continued to operate until the 1980s as 35 Shannon-Library and became the southern portion of 47L Library via Overbrook when Light Rail Vehicles (LRVs) replaced trolleys.

The Washington line was cut back to the county boundary at Drake in August 1953[12] and eventually became the 36 Shannon-Drake.

PRC operated 666 PCCs on 68 routes; the second-largest fleet of new cars (after Chicago), starting with number 100, the first PCC to enter revenue service.

The company took delivery of car 1600 in 1945, which was the prototype for the over 1,800 post-War “all-electric” PCCs built in North America.

Because replacement parts were no longer available, cars 1784 (originally 1603, and subsequently renumbered 1976) and 1779 were rebuilt in 1976 and 1977 respectively, with LRV-style flat fronts.

[22] The last four PCCs were finally retired on September 4, 1999, having been replaced by Siemens SD-400 Light Rail Vehicles.

Pittsburgh Railways inherited many different car barns from the companies that formed it, many of which were closed during the final years prior to take over by the Port Authority.

At the time of the PA takeover on February 28, 1964, only Craft Avenue, Keating and Tunnel (South Hills) remained as streetcar facilities, together with Homewood Shops, and a former carbarn in Rankin used only for dead storage of retired cars.

Craft Avenue assumed storage duties for East End facilities that were closed such as Homewood, Herron Hill and Highland Park, as well as Carrick on the South Side; thus it eventually also served routes such as 22, 71, 73, 76, 77/54, 87 and 88.

Craft Avenue ceased to be a streetcar facility on January 28, 1967 when all East End lines were converted to bus.

[29] The large site is now used for a mixture of residential and commercial premises, with the last remaining railway buildings converted first to a skating rink and then in 1997 to a bowling alley and entertainment venue called the Homewood Coliseum.

Ingram ceased as an active facility after June 21, 1959 when all the West End lines were abandoned after the Point Bridge was closed to traffic, although 30 1000- and 1100-series PCCs made surplus by the conversion were scrapped there.

The final North Side trolleys (6/14 and 21) were transferred to South Hills Car House in 1965 and the facility became the bus-only Ross Garage.

It was closed in the summer of 1954, with services 94 Aspinwall and 95 Butler Street routes being assigned to Manchester Car House until June 1959.

It was then transferred to Craft Avenue car house, also being replaced by buses on November 13, 1960 when the 62nd St. Sharpsburg Bridge was closed.

[43] 5 Generation Bakers now occupies the southern part of the site with a bakery and a retail outlet in a former supermarket building, with new housing to the north.
