Bruce, being a Pittsburgher, thanks for the memories. The inclines were an integral part of transportation, along with the streecars (street railways). There is a nice photo of a model of the South Hills street car junction on page 46 of September MR. My dad was a Pittsburgh Railways street car operator for 44 years, so I am familiar with most of the routes.
I don't recall where the railroad bridge was located.

There were three major railroads in Pittsburgh, the PRR, B&O, and P&LE. The PRR station was majestic, and still there, but is being used for offices and apartments. The B&O was on the Pittsburgh side of the Monogahela River. The passenger station was dead ended, so the trains had to be backed in or out. The P&LE was across the river at the same Smithfield Street bridge, which had two lanes of trolley tracks, and two lanes for autos. That station is still standing, but being used for offices and retail shops.

If you would like any more trivia, let me know.
