The Rocky Mountains Expansion literally expands theWhistle Stop gameboard, adding a 3D mountain range to the game. These mountains provide a barrier that will challenge your West Coast aspirations, but can also provide lucrative rewards for those willing to cross them. Rethink your strategies and come up with new ways to execute the management of your trains to score more fame points than your opponents. In addition to the mountain range expansion board, this expansion contains 5 new End tiles, 4 new Special tiles, 2 additional train route tiles, 2 new variable common resources tiles, 2 new town tiles, 4 new six-point gold nugget tokens, 4 new whistle stop tiles, 2 new gold nugget tiles, 9 new upgrades, and 6 new shares.
