On the "Novocherkasskaya" morning on March 1, a crowd occurred due to a change in the passage scheme in the underpass.
On February 27, in the St. Petersburg metro, passengers were warned of a change in the passage scheme in the “Novocherkasskaya” submarine transition due to the rapid closure of “Ladoga” for repairs.
In order to distinguish the oncoming passenger tramps, during the “peak” hours of working days (from 8 to 9:30 and from 16:30 to 18:30), you can enter the station from the crossing only when driving clockwise. The through transition between the stairs is blocked. The metro published a passage scheme.

In the lobby and in the transition, demarcation barriers and indicators of the direction of movement were installed. However, as eyewitnesses showed in the video, the passengers in the morning did not follow the instructions of the subway and simply climbed over the railing. On the approaches to the station, lines formed .
The head of the St. Petersburg metro Evgeny Kozin apologized for the formed “chaos”, his words are given by Komsomolskaya Pravda. “People were forced to change the route, jumped through barriers,” he said.
Kozin promised that now in the transition to the "Novocherkasskaya" employees of the metro and the police would be on duty, that "to streamline a stream of passengers." The head of the subway expressed the hope that "in the first couple of weeks, people will get used to and develop the correct entry route to the station."
Ladoga will be closed on March 4. The overhaul of the station is hoped to be completed by February 2024.
