While Andy is correct about the local folder, it is located in the User Data folder, and the whole folder is a keeper if you're going to backup or transfer a Trainz 12 installation.

It will be in the Trainz installation folder. The exact location of this depends on whether your version is a Steam version or not.
If you are using Windows Vista or 7, you can right-click the Trainz shortcut and click Open File Location to display the Trainz install folder. (Note that this will not work if it is a version purchased from Steam)
