While the public travels through "palaces for the people"—lavish stations like Komsomolskaya with its crystal chandeliers and baroque mosaics—the secret scheme (sekretnaja shema) is said to lie even deeper. According to urban legends and unconfirmed reports:
: Even the famous Koltsevaya (Circle) Line has its own myths, with some claiming its circular shape was inspired by a coffee stain left by Stalin on the original blueprints.
Today, the "Secret Scheme" remains a favorite topic for "diggers"—urban explorers who spend their nights searching for the entrance to the world that supposedly lives beneath the one we know.
: Unlike the blue-and-white cars of the Zamoskvoreckaja or Sokolnicheskaja lines, the secret trains are often described as internal combustion railcars or battery-powered "stealth" shuttles that run on tracks without a third rail. Traces of the Secret Map
Though the Russian government has never officially acknowledged Metro-2, curious passengers often point to "clues" in the public system:
: Heavy iron doors at the ends of certain transfer tunnels (like those near Sportivnaya) that supposedly lead to the secret tracks.
: While the deepest public station, Park Pobedy , sits 73 meters down, Metro-2 is rumored to reach depths of 200 meters, carved into the very bedrock of the city.
