Here's a pic of the PCC in testing prior to revenue service. Note retrofitted pantograph and digital destination board. Trolley shoes or wheels wouldn't work on a system built for pantographs; the signboard is just a travesty. Photo from Orange Empire Railway Museum e-newsletter:

This is the rebuilt PCC car which debuted on Aug 27 as the start of the Silver Line which circles downtown San Diego. While this car retains its Trolley Pole, it has been updated with a pantograph, LED message sign and a wheelchair lift. Rebuilding this car cost $850,000 plus hours of volunteered work. There are 5 more PCC cars to be rehabbed and added to the fleet. Service for now is weekends and holiday 10AM to 2PM. Photos by Noel T. Braymer.
