Key Takeaways The gauge problem: Soviet railways used a 1,520mm gauge; European railways used 1,435mm. German trains couldn't run on Russian tracks without conversion. The conversion bottleneck: Converting track required enormous labor and materials. At peak efficiency, German engineers converted about 30 km of track per day—far slower than the army's advance. The supply gap: The gap between the advancing front and the end of converted rail created a "supply vacuum" that had to be filled by trucks, which consumed their own fuel and wore out on Russian roads. The cumulative failure: By the time the Wehrmacht reached Moscow's suburbs, its supply system was delivering only 10-20% of required tonnage. The army that arrived was too weak to take the city.
