A relatively simple train game set in North America and involving shares and building railway lines with a few twists thrown in.
Each player uses their investment cubes to bid for control of companies, six in all. When you take control of a company you receive one share, which means that only one share per turn can be purchased. The cubes you bid with go into the company and allow it to build track. Each location has a value which determines how much profit you receive for connecting it. After companies have built as much track as they can players are paid the profit that each company they control has made this turn. Profit levels are reset for the following turn. Players get another set of cubes to bid with and then bid again for control of companies.
At the end of the game each company will pay out an additional amount of profit to each share held. This level is determined by how many different regions a company is connected to. The amount of cash you have determines the winner!
