This incline puts the "fun" in "funicular". It was opened in 1870 (while Ulysses S. Grant was president) and still has some of that 19th century charm. ...Until everyone onboard pulls out their digital cameras and smart phones.
There is a viewing platform near the Upper Station with some nice views of Pittsburgh.
(I wanted to make a joke about it being more like the "Monongahela Decline" but the Incline was too neat to write something like that.)
