Yup, here's what it looks like from the outside:

And if you play around with street view, you should be able to see that there is an elevator next to the escalators. But because there are a few steps to get to the old 1 train platform, they can't label the station accessible. (And the R train platform is down another semi-long escalator with no elevator access IIRC)
