Ah, the legendary North Shore, with the “Electroliner” and its on-board snack bar serving “Electro-Burgers.”
If you haven’t got it, see if you can find the Classic Trains Summer 2013 issue, the BIG interurban issue. There’s a fine article on the North Shore I’m sure you’ll enjoy. Also, “Railfan and Railroad” had a great North Shore article several issues back.
Did you check out that photo website on trolleys I suggested?
I may have but have not found anything on the NJ Palisades interurbans or PSC cars
