No direct transfer to Biblioteka Imeni Lenina originally existed, that was because on the first stage trains went from Sokolniki to Smolenskaya (Kievskaya after 1937) and then onto Park Kultury one after the next. Although transfer corridors were completed soon after, it is unlikely that they were used prior to the opening of the Pokrovskiy radius in 1938 which allowed to separate Arbatskiy from Kirovskiy.
