I have provided links for each Mod, so you can look them over easily. Maps don't need a load order. Just pick a map then start the load order. I like starting from scratch, so these maps don't have Industries, Roads, or Tracks.

This load order has been extensively tested for many hours, and they work as indended. If it doesn't work for you, then it's because your load order is incorrect, or you have a Mod not listed here that is conflicting with another Mod.
