During each turn you may take one of two actions: Either he builds a track section, adding it to a company’s route (building track) and draws a share card or he plays one or more share cards from his hand (investing), placing them on the board.

Building track
1. Select a track card and discard it.
2. Select a company/train from the box and place a train on a corresponding track type.
3. Draw a share card and put in your hand.

Investing
1. Play one or more share cards face-up in front of you.
2. Discard a track card

Everytime a divedend card is drawn from the stack of shares, payment is done for your dividends. The game ends after the fourth dividend card is handled.

I have only made a test play with two players. It's promising, but two is too few.
