Years ago I started thru the academy and finished several lessons. I then proceeded to enjoy Train Simulator for several hours. Now I would like to clear those completes from the academy and start over. Possible? JC
You would need to completely remove your player profile from the files so it will generate a new one iirc.
Uninstall then reinstall TSC. I usually keep my own database of what I have done and not done as the system is not that reliable.
Go to settings. There is a button to reset your progress - it will reset all routes and scenario progress.
