Fabulous riches are discovered in the nearly inaccessible Rocky Mountains. Gold and silver mines are opening in remote boomtowns and the mine owners want men and equipment and supplies to work the Mother Lode. Now, they say, is the time to
build the rails through the Rockies! The sooner a railroad gets to a mine, the greater the profits for the mine owner before the mine is exhausted. The iron horse means money, and lots of it.

Players are mine owners spurring the fledgling railroads through the daunting alpine terrain to the various booming mining districts. There is no luck during the game, just shared incentives and emergent alliances between players. A game for three to five players for less than an hour, designed by the modern master of train games.
