Trainz 2010 and Trainz 2012 restyled the "Main Menu" to this list of Maps (routes) format. Different Route classes are color coded in gold, white or green. * Green indicates locally modified or originated -- the latter case for this image. * White indicates the route is missing at least one asset. If the asset is non-critical, the route and Driver sessions on it's virtual tracks may work fine. * Gold means Built-in content that came with the release of the game.
