The 2017 Edition Includes Updated and Revised Map and Cards for Railways of North America. Railways of North America expands the basic game of Railways of the World (ROTW) to Canada and requires a copy of the base game to play it. Fans of the series will be happy to see new features and an advanced map designed specifically for this expansion. Designed for 2-5 players (but best with 3 or 4) this map has been in development for over a year! This new Canadian map introduces new features – Mines and Ferry Lines – using cards that start out on the table from the onset and can be claimed anytime (just like Railroad Operations cards) for the right price!
