Once the railways get implemented, possibly a basic train model to drive, I'm certain the railsim fans will notice and begin to explore outerra. As far as I know from that community, they are a dedicated bunch of fanatics when it comes to user-made content creation. I am looking forward to that moment with all patience required. (Since 2008 I hoped to find some kind of route in the availlable sims that covers the european continent. So with that in mind, for me it'll be just a short wait from now.)
To the Outerra team: Compliments and many thanks for the work already done!
