The Duquesne Incline is an inclined trolley service (the track is quite steep, so the unusual trolley car is not parallel with the rails) on the south side of Pittsburgh.
The Duquesne Incline wins 5 stars for: novelty, fun for kids, the view from the top and history. Most people take the incline just for the ride (there is parking at the bottom). Photographers have a marvelous opportunity to be creative, and not just with the view from above.
