Moscow metro's Park Pobedy station was still closed Friday morning following a deadly crash earlier this week that killed 23 people.
An underground crossing beneath Kutuzovsky Prospekt at the station was blocked off by police lines, Interfax reported.
Moscow Mayor Sergei Sobyanin earlier promised that service along the Dark Blue Line would be restored on Friday. Test train runs would verify the safety of the tracks before the line reopens for passengers, the report said.
The city has provided free shuttle buses to take passengers along the route of the closed metro section.
Three metro cars skidded off the tracks between the Slavyansky Bulvar and Park Pobedy metro stations on the Dark Blue Line during rush hour on Tuesday morning, claiming the lives of 23 commuters and injuring more than 160 others.
