'Each time the model generates a complete track, it checks for track and train collisions, keeping a record of only the ones that don't cause fatalities.

All of this so far has been very boring and diligent, but necessary. I forgive you for wondering when we're gonna make all those sick layouts we saw at the start. We now have everything we need to build a valid Rail Cube track that avoids most lawsuits, and can start optimising for the aforementioned awesomeness.'
