Missing Scale Test Car Dependencies

I downloaded the scale test cars and all required dependencies from JR, and trainz claims that 3 assets are missing. KUID's 103021:100570, 103021:100569, and 103021:100444:1. I looked them up on trainz kuid search, and I found the download link. I downloaded the .cdp for the dependencies, and installed it. Trainz claims that they are installed, but then if they are, the scale cars would work.

I have this problem too, have you gotten the location of them yet?

Found a bunch of links to the first asset of that list in seconds after entering it into this website:
http://www.trainzkuidindex.com/
Didn't test the others, but would not be surprised if you can find most if not all of them via that website.

I suggest adding that website to your favourites.
