In Gulf, Mobile & Ohio, the third entry in Winsome Games's Historic Railroads System, players build railroads in the South that existed between 1830-1860, with the game board featuring cities from Richmond to New Orleans, and from Memphis to Savannah. Twenty-three different railroad lines exist in the game, each represented by two shares of stock: a charter share for the player who founds this railroad, and a common share that might be auctioned later in the game. Eight railroads are designated as starting lines, and initially only the shares for these eight lines are available to players. Railroad lines will be represented on the game board with wooden cubes that come in six colors, with the number of cubes ranging from 6 to 32.
