We've recently announced our Content Upgrade Program. We plan on filtering through all of our currently available content to ensure that it is error (and in most cases warning) free in Trainz 2012 SP1. When updated content is released they will get a special TRS2012 download button (it's green, see the image above). The updated content will replace any currently installed content, using the KUID2 system, so no work on your end.
Also during this we have a few new projects we are working on and will be released periodically throughout the summer.
