Actually real life railroads as ingame streets
For easier navigation I added roads (using Minecrafts paths block), which have been extracted from OSM data. I used public railways as reference, because there are just to many real roads in areas like Europa and North America. Here is an image of Berlin (top right), the river Elbe and its surroundings.
