The railway system has just been built, and it's your job to get the right trains to the right railway stations. There are dangers everywhere. Bandits infest some of the tracks, so beware! The enemies have patrol cars that won't let you past. Some tracks are broken and need to be fixed before your trains can go over them. You'll need to use every last bit of your ingenuity to get these trains home!
