Trainz has the ability to create excellent scenery, also it was advertised at one time able to run ships and boats on it, so obviously it depends on how you wish to use Trainz. I used it for canals, horse drawn barges, and sailing ships ( mainly my own content), and docks set in age of decades ago before the age of trains, so scenery can be well away from train tracks if you so wish. So there are no hard and fast rules, simply use it whichever way suits your interests, cab driving, train roof driving or driving barges through canal tunnels (train tunnels plus water).
