There are regular subway signs, and then there are the ones that give clear directions—in these cases, using names no longer widely used.
The Port Authority Building, the Art Deco structure built in 1932 that stretches from 14th to 15th Streets on Eighth Avenue, must have been important; it scored its own sign in the station at that corner.
Google bought it in 2010, and it now serves as their famous New York City headquarters. I wonder what old-school Port Authority employees would think of the trick doors in the library and Lego play area.
I’d never heard of the B and D trains referred to as “concourse trains.”
But they made up a branch of the IND called the Concourse Line, opened in 1933 and running from 145th Street (where the photo was located) and 205th Street in the Bronx, under the Grand Concourse.
Penn Railroad sounds quaint, but it’s easy enough to decipher. I wonder how many tourists and new New Yorkers know what BMT and H&M mean—and no, it certainly has nothing to do with the store!
