Age of Steam Expansions
These are different map/boards for Age of Steam and many include special rules. All of them can only be played with the basic game of Age of Steam or its successor, Steam. The official expansions from Warfrog are out of print.
However, I have some expansions designed by Ted Alspach and published by Bézier Games.
America/Europe – double-sided mounted board, with maps of the two continents (North America, in case you were wondering): £20.00
