From the Rules Booklet: Horsepower: 5000 is a card game about railroading. Players use three pairs of decks that they can customize to connect places with rights-of-way and track. They use trains, cars and other special cards to compete for the loads the places produce. Play follows the history of railroading through three phases (from the 1830's through the present). At the end of the game, the player whose empire has the most value and cash wins. Deluxe Set 1 contains 310 cards that can be customized into play decks.
