I photographed a three panel segment of the subway wall and pasted them together for the length of my subway station wall. Today that station also has the pillars on the platform, lighting on the overhead, and soon there will be a level above this with a representation of the city streets. Directly above this line is 7th Avenue with some traffic and pedestrians on it. Broadway crosses 7th Avenue at this station, but that is now a pedestrian mall. I'll make a stab at modeling that too. The tall buildings that live at this location will not be super detailed (after all, street level in this location will already be 6' above the floor line) but will use the computer to generate panels for construction of several buildings.
