I have trainz 2006 sp1. I think I may be able to help. Try putting all the separate files in the cmp and let it do its thing. Edit in explorer and try changing the build number in the config file to the trainz version you are using. Save it and then commit. Before you do any of this, make sure you have all the required dependencies because that is also another problem. If these 2 choices do not work, then you have to do something in the config to fix the problem. Sometimes a train may not work because it is not compatible with the game, error in the config, or error in the texture file. If it works, then there will be some sort of error in 2006 such as a fatal error and it may come up as faulty in the cmp. But if you know how to fix a faulty item, then you are all good to go.
