We have added 72 sheets of a Map of German Railways (Eisenbahnkarte Deutschlands) dated 1937 – 1944. The maps (more diagrams), cover Germany, Austria, and some parts of Lithuania Poland and Czechoslovakia. The set is not complet, but we will try to locate and scan missing sheets. As the maps don't come with any grid lines, it will be harder to create proper index sheets, hence they are available, temporarily, as a list.

Additionally, 34 sheets of the British copy of the same map, dated 1944 / 1945 roku (German Railways) have been made available - they cover western Germany up to Berlin and Austria.
 
From a different source altogether (digital library of PAN), we have obtained a general (Map of German railways (Eisenbahnkarte Deutschlands) scale 1:1125,000., related to the above series.

And from the Library of Congress, courtesy of easteurotopo.org, we have received 12 sheets of a Russian "Map of European Russia and Caucasus”, scale 1:680,000, dated approx. 1870.
