Stephenson's Rocket 1

About Stephenson's Rocket, from BoardGameGeek:

Reiner Knizia expands his fleet of tile laying games with this game about colliding railroads in early 1800's England. There are seven different rail companies that players can expand. Each time you extend a rail, the other stockholders can veto your action, but it might cost them their shares. When two companies' rail touch, the railways merge to become one. The game is over when only one company remains or there are no rail tiles remaining, and the winner is the player who earned the most money over the course of the game.
