A Daniel Burnham masterpiece, fortunately preserved as luxury apartments (you have to go out back by the Dumpsters to catch a train). It was officially Union Station, but usually called Penn Station, since the railroads that were not owned by the Pennsylvania Railroad had their own separate stations.
The East Busway runs right past the building on part of the original railroad right-of-way.
We also have some close-up pictures of the terra-cotta decorations on Penn Station.
Other cities have King Boulevards; we have an East Busway that is officially named for Dr. King, but no one ever uses the whole official name, because by the time you have pronounced the decasyllabic name “Mar-tin Lu-ther King Ju-nior East Bus-way,” you have forgotten what you were talking about. Why not just “King Busway?” We do less honor to Dr. King by using his full name as the name of the busway, because no one ever speaks it.
At any rate, here is the East Busway with two of its stations, in pictures that demonstrate why this busway is such a useful transit artery. Along with the railroad, it runs in a hollow that winds through Bloomfield and Shadyside, giving it the grade separation of a subway without the construction cost. It is in effect a rubber-tired metro line. Pittsburgh invented “bus rapid transit,” and for the most part we did it right.
