In promotion for the debut of the HBO hit series, Boardwalk Empire, HBO has taken over the 2 & 3 trains throughout the month of September, but not the way You'd expect. They're resurrecting a whole subway train from the 1920's to run every weekend all month long! What a cool piece of emersive marketing. Best deal I can get for $2.75 in New York.
