I am not able to find these assets. And I have a bunch more that are faulty and I don't have time to try to fix them all. Well my Alma Valley route was fun while it lasted. That damn bunch of TANE files that I deleted ruined my Trainz experience. Blah.
As HPL says, ensure you have the Additional TANE files installed and also ensure you have patched up to Build 119450. I made that mistake when I reinstalled TRS22+ and everything else a couple of weeks ago. I had a lot of missing and faulty assets. After updating, everything was fine afterwards.
