Catastrophic flooding on 23 September 1924 put the Primorsky Rail Terminal out of commission and all passengers were re-routed to the
Finlyandsky Rail Terminal in 1925.
By 1926, the line to Sestroretsk had been laid through Lanskaya station. In 1929, the line was reconstructed. The stations Flyugov post and Serdobolsky stop were no longer required and they were dismantled.
