@grue Sorry, I got confused by the top comment talking about the Pink Pig.
You're correct, this seems to be a photo of the John Wanamaker monorail in Philly.
"Wanamaker’s maintained a large Toy Department at the south end of the Eighth floor. It included a real monorail for kids that made a circuit around the department from 1946 to 1984, and a sprawling electric-train layout. The rocket monorail cars have been moved to the Please Touch Museum."
