18US is a railroad operations and share trading board game in the 18xx series, to be published in 2006 by Deep Thought Games. The game, designed by David G.D. Hecht as an "advanced" 18XX game, is set in the continental United States. Unlike 18C2C or other, similar products, it is a very compact game: the entire "Lower 48" only takes up two map panels. There are twelve playable companies: two companies can be merged into a System.
