The Station Square subway station was built in the 1980s, when the streetcars were diverted from the Smithfield Street Bridge to the Panhandle Bridge and into the subway downtown.
Even though it’s clearly above the ground, this is the end of the section of combined trolley lines that Pittsburghers call the “subway.” From here the outbound streetcars go underground into the Mount Washington tunnel, but that’s not a subway. That’s just trolleys running underground. You need to be a Pittsburgh native to follow the logic.
The entrance to the Mount Lebanon station on the Red Line. The station is at the end of a winding subway tunnel cut through the rock (although Pittsburghers never call it a “subway,” reserving that epithet for the downtown section of the system). To get to the station from the Washington Road business district, you have to enter here, go down a flight of stairs (or an elevator), cross an alley, and go down another flight of stairs (or another elevator). Below we see the alley crossing and the station beyond it.
This entrance was built in the fashionable postmodernist style of the 1980s, when the streetcars were moved from Washington Road into the subway. Old Pa Pitt is impressed by the architect’s forethought in providing for the entrance to be tightened with a giant screwdriver if it should ever start to come loose from the ground.
