18GL is a railroad operations and share trading board game in the 18XX series, published by Deep Thought Games, LLC in 2006. The game was designed by Gary Mroczka and is set in the Great Lakes area, United States. It uses basically the same rules as David G.D. Hecht's 1826 except that there are no destinations, there is only one merger, and instead of TGV trains there are Diesel trains. The map is quite different, and the private companies have the effect of altering how the map develops depending on the combinations of private companies and corporations particular players get.
