Below is a 1935 topo map of the Weehawken Terminal area (showing the ferry route to W. 42nd Street, too.) Free Maptech topo map downloads are available here. I was looking at Google Streetview but the area has changed so completely as to be virtually unrecognizable.
Thank you for the pictures. That staircase must have been one helluva climb. I took my first railroad (as opposed to subway) ride on a River Division train from Weehawken to Fort Montgomery . Its a shame that so much of that is gone but at least the Weehawken Tunnel is back in service and their is once again a ferry service between Weehawken and 42 street.
