New York Subway System

Since it would pretty much be completely invisible anyway, why would anyone want to? That would be like modelling the Chunnel.
:D
 
Just a guess but I bet after tim warris see this and finishes his bronx yard he might? It would take someone like him to pull it off. lol
 
That is an awesome map. I've been intrigued by subways and subteranean railways (current and abandoned) for quite a while but it all started with the tube when I took summer classes in London in '93. Neat stuff. Also, as an ex-cartographer, I can appreciate the work that went into the map as well.
