There are probably hundreds -- if not thousands -- of on-line pictures of New York City subway cars and stations.
But I can't find any decent photographs -- or drawings -- of the elevated structure suitable for starting to model it. I'll probably take some of my own pictures later this year but it would help if I could find some preliminary on-line material first.
Anyone know of any on-line sites with good pictures or drawings of the "el"? How about books?
