I am also puzzled by the debate about Amerika or Erika. All literature references to this train speaks about 'Amerika'. On the 1st of Febr. 1943 it's codename was changed to 'Brandenburg', I believe. My sources also tell that the commander of this mobile FHQ in 1939, was none less than Erwin Rommel? The train was appearently 'shadowing' Hitler to his various headquarters, i.o.w. - it was mostly parked at or near Rastenburg. The composition of the train that I have closely follows Andre's;
2 locomotives, Befehlswagen,Nachrichtenwagen, Hitlers Wohn-und-Arbeitswagen,Begleitkommandowagen,Speisewagen, 'a few' Gäste-und Schlafwagen, Pressewagen,Gepäckwagen and 2 FLAK-carriages with 20mm guns. Quite a train indeed and I believe Göring and Himmler also had similar 'rolling HQ's'. What a nice idea Andre - to recreate Am-Erika in HO scale!
