Once you have played a number of custom maps you will likely want to try and make your own. Luckily after the 1.1 patch Fraxis enabled added in-game map editor. This editor is not enabled by default nor is there any option in the game to enable it. Instead you have to edit your settings.ini file. You must add a line to your Settings.ini file found in your user data folder which by default is C:\Documents and Settings\My Documents\My Games\Sid Meier’s Railroads!.  To do this open Settings.ini in notepad and add EditorEnabled = 1 on a new line in the [User Settings] section. Then start th game again and there will be a “Map Editor” option in the main menu. Once you have created your map do not forget to post it in the forum, so that it can be included in the map list. Happy map making!
