Thank you for playing our game and taking the time to provide feedback. We probably should have added a short tutorial or something to make getting started easier.
As for the map, it is intended to look like this, but we've noticed that Chrome/-ium somehow fails to render the track, unfortunately. About this crash, we would like to look more into it, any chance you could give us some direction on how to reproduce that?
About the trains, we are fairly sure that trains only start moving if commanded to do so. However, we've encountered similar issues, which were generally caused by outdated commands (after editing a train) or accidental edits when switching between trains. Obviously, the user experience is still a bit rough and could use several improvements.
