I hope this thread is in the right place I have loaded trainz 2010 and some of the consist shoe up red and these are ones that came with the trainz 2010 also I cant download aircraft as they show up red as well. I have got windows 7 and a 8gb hard drive.
If you mean red text for the asset names, this means that they are faulty or have missing dependencies. There is a thread in the TS2010 forum relating to false positives though that you may want to read.

hard drive.
