Starting tomorrow, September 3, HBO will market Boardwalk Empire in Manhattan in a pretty high concept way: "an authentic vintage 1920’s train will run on the express 2/3 track in Manhattan" on Saturdays and Sundays in September from 12 p.m. to 6 p.m. The train will run until September 25, when the second season of Boardwalk Empire premieres.

Check out the images above.
