The Breitspurbahn (German pronunciation: [ˈbʁaɪtʃpuːɐ̯baːn], translation: broad-gauge railway) was a planned 3,000 mm (9 ft 10 1⁄8 in) broad-gauge railway, proposed by Adolf Hitler during the Nazi regime in Germany, supposed to run with double-deck coaches between major cities of Grossdeutschland, Hitler's expanded Germany,[1] and neighbouring states.
