Good eyes indeed, Uptowner. We still can barely make out that Sixth Ave. Line lettering on the station, even after it was pointed out. That is the elevated train line that ran up Sixth Avenue, crossing 58th street at the terminus right before Central Park. The building on the near right with the banded rustication is the Coronet, a pre-war apartment house built in 1901 that still stands today at 57 West 58th Street. The Sixth Avenue El did not survive. The elevated train continued until December of 1938, when it was decomissioned—replaced by a subterranean way. Thanks for playing!
