18FR (1997)

An 18xx game originally designed in 1987 by Michael Liebetanz as 1830: Railways & Robber Barons on a new map, in 1997 Helmut Ohley produced a variant set of rules for 18FR which introduced ports, the special track-tiles, etc. In 2009 J C Lawrence in collaboration with Helmut Ohley updated 18FR, extending and clarifying Helmut's original variant into a more interesting game. Both variants require additional components to 1830: Railways & Robber Barons to play (files are provided to make your own) and assumes familiarity with the 1830: Railways & Robber Barons rules.

Though this uses components of 1830 this is not an expansion, but is a separate standalone game.
