TRS19 SP3 Release Candidate now available

The trick is to realize that directories and storage of Trainz files is nothing like you are used to with windows.
There is no need to move cdp's around, the game manages all.
Concentrate on developing a new route or running a built in one.

Also there is no need to download all of the files from the Trainz data base, you only require those associated with the built in routes with the exception of those required for any new routs that you create requiring additional cdp's.
Testing build 111956 with Mac OS Monterey public beta 2, no sound at all. Just an FYI as it will be a while yet before Monterey is released. Other games and apps do have sound.
