The Battle of Berlin was a campaign spread over a large area. The city itself was the megapolis of Europe, much bigger than Stalingrad. The HOB rendering was focused on part of the Z defensive zone where some of the best known tactical engagement took place (i.e., Reichstag, Ministry of the Interior/Himmler's House, etc.). From the presence of a large railyard and adjacent train station, this might be an ASL rendering of the brutal fighting to take control of the Anhalter Bahnhof.
