In all likelihood. Let me formulate the question somewhat differently. That is how I relate to this. I have nothing to do with any secret metro and can only surmise about it. Lyuba Pronina Much has been said about it.
Muscovites blame occasional street collapses on it.
Diggers of the Underground Planet, headed by Vadim Mikhailov, self-pronounced king of the subterranean world, claim it's a vast network, some of which they have been lucky to see, and say it should be used for the good of the city. Even in Soviet times, when much was closed to the average citizen by the heavy veil of state secrecy, there were rumors of an underground system and tales of the almost palatial beauty of the hidden bunkers. Moscow old-timers speak of Josef Stalin's special metro, which could take him into any part of the city. The rumors stemmed from his ability to appear in different places within very short intervals of time. Residents of Prospekt Vernadskovo have always wondered about the idle plot of land spanning the way to Yugo-Zapadnaya station, an obvious place to be built on which has never been used.
