They should be in your CMP under "My Content", and you save them as a CDP, and transfer that CDP you made into 04.
I have a TRS2006 route that I will backdate the config file, and I want an TRS2004 user (or UTC user) to test it to see if it will install in their game.
What is your trainz-build line in a route that you made, so I can backdate my route to your build ?
