You can also make a backup of your Local Data Folder.
Open the Launcher > Install tab and copy that Path into Windows Explorer (or Finder for Mac)
To be safe, ensure that the TANE folder and all subfolders are backed up regularly. (using the default path it will look something like; C:\Users\<username>\AppData\Local\N3V Games\TANE
To restore, you can rename the existing folder to TANE-OLD (or delete it if you are really sure you want to), and replace it with the old backed up version.
This process ensures your pathname remains the same and Trainz simply loads the older copy of the data.
