Originally intended to have been one of the pioneer order of 100 PCC cars bound for Brooklyn and Queens Transit, the 100 (the second car of the lot produced by St. Louis Car Co.) was diverted to Pittsburgh instead, and an additional car was constructed for Brooklyn to replace the lost unit. The car was equipped with locally-produced Westinghouse air brake equipment as a demonstration, which may well have been the principal reason behind 100's delivery to Pittsburgh. Delivered to Pittsburgh Railways in June 1936, car 100 entered service on July 26, 1936. Its operation in demonstration service and then revenue service on route 50 predated the inauguration of PCC operation in Brooklyn, thus making car 100 the very first PCC car to operate in revenue service anywhere in the world.Disposition:
The 100 was converted to instruction car M11 in 1950. By 1967, this unit was perhaps the oldest PCC car still retained on the roster of a transit system, although both M11 and PRCo were effectively in dead storage; PRCo had been succeeded by PAT as operator of Pittsburgh's remaining street railway services in 1964. M11 was not to be among those PRCo cars accepted by PAT, and was scrapped shortly thereafter.
1000-1099 (100 cars)
Builder: St. Louis
Trucks: Clark B-2
Motors: WH1432 (1000-1074), GE1198 (1075-1099)
So impressed were the management of PRCo with the performance of car 100 that they placed an order for 100 more cars the same month.
All scrapped in 1963, except 1138, which had been acquired by the Arden Trolley Museum in 1961.
In 1962, car 1276 was converted to a works car with a front-mounted wedge plow, and renumbered M1276. The following year, 58 cars were scrapped. The balance of the cars were placed in storage until final disposition.
All cars scrapped or stored by 1967, having been made surplus by the wholesale abandonment of remaining East End routes in January, 1967. Car 1440 was acquired by the Seashore Trolley Museum in 1968.
Car 1547 was diverted to Twin Cities Rapid Transit (Minnesota) prior to delivery, where it became TCRT 299. A replacement car, also numbered 1547, was delivered to Pittsburgh in its place. Like the 1400s, the remaining 1500s fell victim to the East End abandonments of 1967, and were scrapped.
Numerous cars rebuilt/repainted/renumbered in the 1970s. They remained air cars, but received 1700-series numbers, and (in three cases, at least), became double-ended by the installation of experimental backup equipment.
