If you originally used the default localdata location, then the location shown in the Trainz Settings will give you are start point for locating your old LocalData as well.
Thanks Zec for this information but it does not make sense to me as I use a Mac, and art does not give me any direction to find my local data
Any chance you can give me directions in Mac speak
God bless you

Just use Spotlight search and look for "assets.tdx" or "content-store-task-list.tdx" to find your user data folder. These files are IN the data folder.
