*Thanks for the compliments regarding the 2nd Avenue Subway page.  I think the original Second Ave page covers it pretty well too.  Perhaps the parts to keep from 2nd Ave version are the A New 21st Century Attempt and See Also, because they have relevant information that isn't covered in the orginal artical and the links are useful. 
 :Regaring the image of the 2nd Avenue Subway from the MTA website.  The one arguement I would make in favor of using it is the fact that it comes from a publicly released PDF document about the project scope.  It seems to me that such a publicly required document should be rather easy to reuse in a non-commercial format like Wikipedia.  

 :*As I said on the images talk page, the problem isnt the legality as much as it is wikipedia policy. We can only use images that are Public Domain, Fair Use, or Licensed under GFDL or similar licenses. This is none, so although it might be legal (a debatable fact anyway), its still against our policy. If i have time i might recreate a image to replace it with. -  .:.
