@Railroader1970 - Yes. But I have been reading in various posts that TRS22 does not see/show SOME older content, regardless of trainz version.
Give it a try, see if it works properly for you.
There will be, of course some asset incompatibility, since TRS22 error checking is much more strict than what was used in TRS12.
Likely have alot of texture.text conversions to do, and possibly some missing environmental.bmp file issues. There are other errors that can show up, but I can't think of them atm. Like all of us who have moved TRS12 stuff into TANE TRS2019 and 22, you'll have to go through the process (maybe).
There will also likely be some TRS12 ONLY content you will need to manually cdp over as well.
There is a suite of tools for correcting most of the errors here -
PevSoft Trainz Tools.
There's a lot of info on using them on this forum, so first search this forum for answers, or post a help request topic for each error type you will be fixing.
