25 years ago the first version of 1847 had been developed. It based on 1835 and had been designed for 3 players. The game was provided as a game kit for all who are interested. The game kit contained the map, the shares, the train cards and station markers. Everything else had to be taken from a copy of 1835. Over the years new versions had been developed with updated maps and expansions for 4 and 5 players, which eventually were available as RTP versions only.
To celebrate the 25th anniversary 1847 has been redesigned again. The map has increased slightly and there is another railway corporation as new private companies. The Anniversary Edition will contain both, the old “Standard” version as well as the new Anniversary version and tow variants.
