Are iCloud saves supported?
Yes. Your Sid Meier's Railroads! saves are automatically backed up to your iCloud account. It is recommended that you wait a few minutes after syncing before attempting to load a cloud save on a different device.
Please note: When not connected to the internet, you may play Sid Meier's Railroads! in offline mode. When you are next online, you may either sync your local save files to the cloud, or overwrite them with your existing cloud saves.
If any local files are deleted while in offline mode, they will be automatically redownloaded from the cloud when next online.
