Is there a way to slow the time down, without messing up the AI? I mean the years sprint by way too quickly and this is currently the main reason I may not buy the game.
Is there a way to make the maps bigger? It takes far too short a time for the trains to move from stop to stop.
Is there a fix for the tunnels and bridges? At the moment, double tunnels look terrible!
Is there a way to stop trains running into each other and make them wait at signals properly?
Thanks in advance for any help!

Edit: I've played the demo extensively, without a single CTD. Should this be the case with the full game (I've noticed several people here having CTD problems)?
