Confessing complete befuddlement, Ivan Parmar, 21, a real estate agent from Borough Park, Brooklyn, stood at the downtown B and N platform at Herald Square yesterday morning, next to a Metropolitan Transportation Authority poster that read in part, "Sometimes you have to go backward to go forward."
Indeed. I haven't fully explored Herald Square since the change, but when I rode through that station on the downtown B train yesterday, it pulled in on the 6th Avenue platforms. (That is, it pulled in on the same platforms as the F, V, and D trains.) The N, Q, and R use the Broadway platforms. I can't imagine why there would be a B and N platform anywhere in that station.
