Fabulous riches are discovered in the 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, it's time to build the tracks 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 a lot of it.

There is no luck in the game, just shared incentives and emerging alliances between players. A game for three to five players for less than an hour, designed by the modern master of train games.
