Philadelphia Rapid Transit Co. (PRT) was the largest trolley company that was not a member of the coalition that designed the PCC streetcar.

Perhaps this was because its existing trolleys were somewhat newer than average at the time, but in 1938 PRT took delivery of twenty PCCs anyway, running on Wayne Avenue’s route 53. In 1940, successor company Philadelphia Transportation Co. (PTC) ordered 130 more, and the following year—worried that impending war would shut off availability of new cars—bought an additional 110. Philly’s new PCCs soldiered hard, carrying the wartime crush of riders, and may have saved the system from early bus conversion.

Car No. 1060, which Muni acquired from Philadelphia, models the original PTC livery of silver with cream window area and electric blue striping. The similarity to the packaging of Kraft’s famous ‘Philadelphia Cream Cheese’ did not go unnoticed, providing the car a nickname.

Car No. 1060 was originally painted to represent Newark, New Jersey. In November of 2002, the car suffered severe body damage when she took a curve at Market and Steuart too fast, jumped the track, and hit a lightpost. Muni repainted her in the 1938 silver and blue Philadelphia livery originally worn by wrecked PCC No. 1054. One of the actual Newark PCCs acquired by Muni in 2003—with Market Street Railway's support—will be painted in the historic livery previously worn by No. 1060. In Philadelphia, this car was numbered 2715.
