Union Station is a quick-playing cube rails game for 3-5 players, focusing more on share purchasing and stock manipulation than route building. On your turn you may either buy stock and increase its value, sell all of your stock to get quick cash while also lowering the company's value, or lay track. While the shares might come out randomly, it's all about careful timing and the willingness to drop something good for something even better.
The game ends immediately when all of the Shares have been bought or sold off, 20 dividends have been paid, or railroad companies cannot lay any additional track. The players add together their cash in hand to the value of each of their shares, and the player with the most money wins.
