Pnumatic subway

Wired has a facinating story about New Yorks first attempt to build a subway in 1870 – 40 years before the real one came.

Think mail delivery tube systems. The project failed due to concerns about building safety, but the story is amazing. Read more about it here and see amazing pictures.
