"The Allies described the wartime military alliance of Germany, Austria-Hungary, Bulgaria and the Ottoman Empire as the 'Central Powers'. The name referred to the geographical location of the two original members of the alliance, Germany and Austria-Hungary, in central Europe."

"The geographical position of the German and Austro-Hungarian empires also gave the Central Powers at least one very important strategic advantage over the Allies they were fighting. It was much easier for the Germans and Austro-Hungarians to move troops, equipment and supplies from one battle front to another because they could do much of this on their domestic railway networks."
