The station was named for the workers of the Komsomol youth league who helped to construct the first Metro line.

Temporary bridges were built over the construction site to avoid disrupting traffic, especially the numerous tram routes in the area.

Heavy rains in the summer of 1934 threatened the construction site several times, and at one point even the Kazansky terminal was in danger of collapsing.

Due to Komsomolskaya's location under a major transit hub, the station was built with an unusual upper gallery above the platform to help handle rush crowds.

The station has tall pillars faced with pinkish limestone and topped with bronze capitals displaying the emblem of the Komsomol league.
