The Union Pacific is one of the largest railroad companies in America with rails connecting many of the largest cities. To further enhance its range, it has arrangements with smaller companies to use their rails. This allows the Union Pacific to serve even more cities. The map shows the ten smaller companies with their starting cities and possible track sections they may build. Each track section connects two cities and has spaces for one or more trains. The number of spaces indicates how many companies may build track along the section. The players are shareholders of the railway companies and fight for the stock majorities in the companies. They also develop the railway systems by building track for the companies. By building track for the companies they have large holdings in, the players attempt to earn large dividends and end the game as the richest player.
