Dumb nitpicking, sorry: The railroad car was used in 1918 and in 1940. In both cases Germany was unoccupied, in WW1 because the war was fought on French and on Flandern fields, in 1940 because it was the beginning of the war. You're possibly thinking of the German surrender, first in Reims, then a day later again in Berlin.
