The last map in my Germania map series showing the complete German domination of the continent after winning WW2.
The red lines show the Autobahns that were built in order to connect this vast empire. The black rail like lines show the extremely wide gauged railroad (3 meters wide, twice as wide as railroads are today) that were to be constructed as Germany's version of shipping routes on sea. What's the point of having the largest empire in the world if you don't also have the largest trains, right?
The cities (or rather, fortresses) of Nordstern (Trondheim) in Norway, Westhafen (Le Havre), Scherburg (Cherbourg), Brest and Sankt Nazer (Sainte-Nazaire) on the French Atlantic coast and Weißenburg (Belgrade) in Serbia were turned over to the Germans to ensure the safety of the Reich. The final peace treaty with France saw roughly all the territory that once belonged to the HRE be annexed by Germany, while Brittany was made an "independent" state comparable to the pro-Nazi Slovak Republic. Italy recieved Savoy, Nice (the entire departement, not just the old county) the Alps in between them, Corsica and Tunisia.
