IND Second System maps

I saw these two second system maps on wikipedia today. They are re-printed from "Twelve Historical New York City Street and Transit Maps from 1860 to 1967"

This one is from 1929:

And this one's from 1939:

Both are public-domain because there is no copyright.

What was the IND second system going to be? Is there a link?

Read "The Routes Not Taken" by Joseph Raskin.

May I suggest you Google "IND second system"? You will find many links.

Thank you NW.

<Bump>. Someone mentioned the IND Second System in another thread: I thought I'd add some resources, and ask the question which of these lines would be feasible today? Which in hindsight should have been built? Which was not useless?
