This is the first expansion for Amabel Holland's Dual Gauge. Honshu is a small, cutthroat map for three to four players. Money is tight and the terrain unforgiving. Along the way, you and your opponents will help industrialize Japan's largest island, upgrading low-paying dits into profitable cities. (In fact, failing to do so will result in end-game penalties!) Of course, cities can be tokened, allowing you to create chokepoints on the fly. A nasty, nasty map. The second map shifts the scene to exotic and fantastical Wisconsin. This is a sprawling "big money" map for three to five players. The major gimmick here is that there are nine 5Ts, and these trains are "diesels" – running as far as you like along a stretch of compatible track. Plan carefully in the early game, and you can end up with a triple-digit run in the last couple Operating Rounds. But an inconvenient change in gauge or station can stop your diesel before it leaves the station. When the base game came "back in print" in 2021, we added Company Charter cards. Those cards are also included in this expansion for our early adopters.
