Similar to Streetcar, Tsuro, Tantrix and Spaghetti Junction, this game has players putting square tiles onto the board to form rail lines. The major difference in this game, however, is that players are not striving to make short, direct routes like those sought in Streetcar. Instead, the object of the game is to make the rail lines as long as possible.
Players start with a number of trains ringing the board. Whenever a tile placement connects a train to a station (either on the edge or the center of the board), that train is removed and the player scores one point for each tile that the route crosses, which can cause one tile to score multiple times if the track loops around. However, players score double for city connections, which are the stations in the center of the board.
