BANG! The Great Train RobberyExpansion

From BoardGameGeek:

Expansion for BANG! card game. This expansion is co-designed with Czech and Slovak players and brings new mechanics, new cards to be shuffled with the basic deck, and 8 brand-new characters. The expansion focuses on a track of Railroad cards and a Locomotive card: Each Railroad card is coupled with a Station tile; every time the Sheriff's turn begins, the train moves and the value of the Railroad cards change depending on the Station tiles. Once during their turn, players may pay the cost shown on a Station to take the corresponding Wagon. There are two kinds of Railcars: blue-bordered Railcards stay in play until discarded, and take effect immediately; while green-bordered Railcars stay in play but have no effect until the owner decides to discard them during their turn. If a Railcar is taken, the other Railcars on the train slide up to cover the gap, and a new one is added to the end of the train. As soon as the first Railcar behind the Locomotive goes past the last Station, the Locomotive card's special effect triggers for all players. Then a new track of 5 Station tiles, as well as a new train, is built in the center of the table.
